Clear Aligner (Invisalign)

Invisalign Clear Aligners in Rangsit, Pathum Thani

Invisalign is an orthodontic treatment that uses a planned series of removable, transparent aligners to move teeth gradually.

Each aligner is made to fit the patient’s teeth at a particular stage of treatment. As the patient progresses through the prescribed series, the aligners apply controlled forces intended to move selected teeth toward the positions planned by the treating dentist or orthodontist.

Clear aligners can be a discreet alternative to conventional braces, but they are not automatically the best choice for every patient. Suitability depends on the type and complexity of the bite problem, tooth position, gum and bone health, age, lifestyle and the patient’s ability to wear the aligners consistently.

A clinical examination, dental records and appropriate imaging are required before an individual treatment plan can be confirmed.

What Is Invisalign?

Invisalign is a brand of clear aligner system used for orthodontic treatment.

Instead of brackets and wires being fixed to the teeth, the treatment uses a sequence of removable aligners. Each set is designed to produce a planned amount of tooth movement before the patient changes to the next set according to the treatment schedule.

The aligners are made from transparent material and fit closely over the teeth. However, they should be described as discreet rather than completely invisible. Depending on the treatment plan, tooth-coloured attachments, buttons or orthodontic elastics may also be required.

The aligners can normally be removed for eating, drinking beverages other than plain water, brushing and flossing. They must then be placed back over clean teeth and worn for the number of hours prescribed by the treating dentist.

What Dental Problems May Invisalign Address?

Clear aligners may be used to treat a range of tooth-alignment and bite problems, including selected cases of:

Crowded teeth
Gaps between teeth
Teeth that have shifted after previous orthodontic treatment
Rotated teeth
Protruding teeth
Deep bite
Open bite
Crossbite
Increased overjet
Mild or moderate bite irregularities
More complex orthodontic problems when suitable auxiliaries are included

The ability to treat a particular condition cannot be determined from the appearance of the front teeth alone.

The dentist must assess the relationship between the upper and lower teeth, the position of the roots, the supporting bone, jaw growth where relevant and the way the teeth function during biting and chewing.

Some complex movements may require attachments, elastics, additional aligners, tooth reshaping, extraction or another orthodontic method.

Who May Be Suitable for Invisalign?

Invisalign may be considered for adults and teenagers who:

Want a more discreet orthodontic appliance
Are willing to wear aligners for the prescribed number of hours
Can remove and replace the aligners responsibly
Are able to maintain good oral hygiene
Can attend scheduled progress appointments
Have healthy or appropriately treated teeth and gums
Understand that aligners may still require attachments or elastics
Are willing to wear retainers after active treatment

Clear aligners can be particularly convenient for patients who prefer to remove their appliance for meals or important activities.

However, removability is only an advantage when the aligners are returned to the mouth promptly. Leaving them out for extended periods may reduce tracking and delay treatment.

Who May Need Additional Assessment?

Further evaluation or preliminary treatment may be needed for patients with:

Untreated tooth decay
Active gum disease
Significant gum recession
Loose teeth
Poor oral hygiene
Missing teeth
Dental implants or extensive bridgework
Impacted teeth
Severe crowding
Significant jaw discrepancy
Teeth with short or compromised roots
Temporomandibular joint symptoms
A history of orthodontic relapse
Difficulty committing to the required wear schedule

Patients with swollen or bleeding gums may need gum treatment before orthodontic treatment begins.

Existing crowns, veneers, implants and fillings do not always prevent Invisalign treatment, but they can affect attachment placement, movement planning and the overall treatment strategy.

Invisalign Is Not Just a Cosmetic Treatment

Many patients first consider clear aligners because they want straighter-looking teeth. Orthodontic planning must also consider function and oral health.

The treatment plan should evaluate:

How the upper and lower teeth meet
The amount of space available
The position and inclination of the teeth
Root position
Gum and bone support
Jaw relationship
Lip and facial profile
Previous dental treatment
Long-term stability

Moving only the most visible front teeth without assessing the complete bite may create an unstable or unsuitable result.

For this reason, Invisalign treatment should begin with a professional examination and continue with clinical monitoring rather than relying only on a remote scan or computer-generated preview.

Invisalign Attachments, Buttons and Elastics

Some Invisalign treatment plans use more than the clear aligners alone.

Attachments

Attachments are small shapes made from tooth-coloured dental material and bonded temporarily to selected teeth.

They give the aligners additional grip and may help produce movements such as:

Rotation
Root control
Extrusion
Intrusion
Moving teeth bodily rather than only tipping them

Attachments may make the aligners slightly more noticeable, especially at close range. The number, size and position depend on the movement required.

Buttons and elastics

Buttons or small hooks may be used with orthodontic elastics to help correct the relationship between the upper and lower teeth.

Elastics must be worn according to the prescribed schedule. Inconsistent use can affect the progress of treatment.

Interproximal reduction

Interproximal reduction, sometimes called IPR, involves carefully removing a very small and planned amount of enamel between selected teeth to create space.

It is not necessary for every patient. The amount and location must be determined from the orthodontic plan.

Tooth extraction

Some orthodontic cases require tooth extraction to create space or improve the bite and facial balance.

Not every crowded case needs teeth removed. The decision depends on the severity of crowding, tooth position, facial profile, jaw relationship and treatment objectives.

Invisalign Treatment Process at SWC Dental

1. Orthodontic consultation

The first appointment includes a discussion of the patient’s concerns, treatment goals, dental history and previous orthodontic treatment.

The dentist examines:

Tooth alignment
Bite relationship
Gum condition
Existing restorations
Missing or impacted teeth
Jaw movement
Facial and smile proportions
Oral hygiene

The dentist will also discuss whether Invisalign, conventional braces or another approach may be more appropriate.

2. Dental health assessment

Active dental and gum problems should normally be managed before orthodontic movement begins.

The patient may require:

Teeth cleaning
Treatment for gum inflammation
Replacement or repair of leaking fillings
Treatment of active tooth decay
Assessment of painful or infected teeth
Evaluation of impacted wisdom teeth

Starting aligner treatment with untreated dental disease can make cleaning and ongoing care more difficult.

3. Photographs, scans and imaging

Orthodontic records may include:

Facial photographs
Intraoral photographs
A digital scan of the teeth
Bite records
Panoramic X-ray
Cephalometric X-ray
Additional imaging when clinically indicated

The type of imaging depends on the patient’s age, condition and treatment complexity. Advanced imaging is not required for every Invisalign patient.

Information about available imaging can be found on the 3D Digital X-ray Center page.

4. Digital treatment planning

The records are used to create a digital representation of the teeth and a proposed sequence of movements.

The dentist reviews and adjusts the proposed plan according to the clinical diagnosis.

A digital simulation is a treatment-planning and communication tool. It illustrates the intended direction of treatment but should not be presented as a guarantee that the biological response or final result will match the animation exactly.

5. Review of the proposed treatment

Before treatment begins, the dentist discusses:

Main orthodontic problems
Treatment goals
Expected limitations
Estimated treatment duration
Possible attachments
Possible elastics
Possible IPR
Whether extraction may be considered
Number and frequency of appointments
Retainer requirements
Estimated treatment fee

Treatment duration and the number of aligners can change according to how the teeth respond and how consistently the aligners are worn.

6. Aligner delivery

At the delivery appointment, the dentist checks the fit of the first aligners.

When required, attachments or buttons are bonded to the teeth. The patient is shown how to:

Insert and remove the aligners
Clean the aligners
Check that they are fully seated
Use aligner-seating aids if prescribed
Store aligners safely
Follow the change schedule

7. Progress appointments

Regular reviews allow the dentist to assess whether the teeth are following the planned sequence.

The dentist may check:

Aligner fit
Attachment condition
Tooth movement
Bite changes
Gum health
Oral hygiene
Patient wear routine

Do not move to the next set earlier than prescribed unless instructed by the treating dentist.

8. Additional aligners or refinement

Some patients require another digital scan and an additional series of aligners after the first series.

This is commonly called refinement. It may be used when selected teeth need further movement or when the bite needs additional adjustment.

A refinement should not automatically be considered a treatment failure. Biological tooth movement does not always occur exactly as predicted, and additional stages may form part of the individual plan.

9. Retainers

After active tooth movement is completed, retainers are required to help maintain the new positions.

Teeth can shift after any form of orthodontic treatment, including Invisalign and fixed braces.

The type of retainer and wear schedule depend on the patient’s bite, treatment history and risk of relapse. Retainer use is a long-term part of orthodontic care rather than an optional final accessory.

How Many Hours a Day Should Invisalign Be Worn?

Many Invisalign plans require the aligners to be worn for approximately 20–22 hours per day, but patients should follow the schedule prescribed for their individual treatment.

Aligners are normally removed for:

Meals
Snacks
Drinks other than plain water
Brushing
Flossing
Cleaning the aligners

Frequently leaving the aligners out for long periods may result in:

Poor aligner fit
Teeth not tracking as planned
A need to wear a set for longer
Additional appointments
Additional aligners
Extended overall treatment

The success of removable aligner treatment depends substantially on patient cooperation.

How Often Are Invisalign Aligners Changed?

A patient may be instructed to change to a new set according to a weekly or another individually prescribed schedule.

The appropriate interval depends on:

The planned movement
Aligner fit
Patient age
Biological response
Wear time
Treatment stage
Complexity of the case

The aligners should not be changed faster simply to shorten treatment. Moving to a new set before the previous movement has occurred can cause poor tracking.

How Long Does Invisalign Treatment Take?

There is no single treatment duration that applies to every patient.

Treatment time depends on:

Severity of crowding or spacing
Complexity of the bite
Number and type of tooth movements
Need for extraction
Use of elastics
Growth and jaw relationship
Patient cooperation
Aligner wear time
Missed appointments
Lost or damaged aligners
Need for refinement
Individual biological response

A relatively limited alignment problem may require fewer stages than comprehensive bite correction. An individual estimate can only be provided after examination and treatment planning.

The estimated timeline may be revised during treatment if the teeth do not move as expected.

Does Invisalign Hurt?

Patients may experience pressure, tightness or mild soreness when beginning a new aligner.

This sensation is related to the force being applied to the teeth and often reduces as the patient adapts. The intensity varies between individuals and between different stages of treatment.

Other temporary concerns may include:

Tender teeth
Irritation of the tongue or cheek
Difficulty removing a new aligner
Increased saliva
Temporary changes in speech
Sensitivity after IPR
Discomfort from elastics

Clear aligners should not be promoted as painless. Contact the clinic if there is severe pain, a sharp or damaged edge, significant gum irritation, swelling or an aligner that no longer fits properly.

Eating and Drinking with Invisalign

Aligners should normally be removed before eating.

Plain water may usually be consumed while the aligners are in place, but follow the treating dentist’s instructions.

Remove the aligners for:

Coffee
Tea
Soft drinks
Juice
Alcoholic drinks
Milk
Sweetened beverages
Hot beverages

Drinking coloured or sugary beverages with aligners in place may increase staining and expose the teeth to sugar or acid for an extended period.

Hot water and hot drinks may also distort the aligner material.

After eating:

Clean the mouth appropriately.
Clean or rinse the aligners as advised.
Reinsert them promptly.
Store them in their case whenever they are outside the mouth.

Avoid wrapping aligners in tissue, as they can easily be thrown away accidentally.

Cleaning Invisalign Aligners

Clean the aligners according to the instructions provided by the dental team.

General care may include:

Rinsing them after removal
Cleaning them gently with an appropriate soft brush
Using the recommended cleaning product
Rinsing away all cleaning residue
Keeping the storage case clean
Avoiding hot water
Avoiding abrasive toothpaste unless specifically recommended
Keeping aligners away from pets

Do not use bleach, household cleaning products or strongly coloured mouthwash to clean the aligners.

Cloudiness or odour may develop if plaque and food residue remain on the appliance.

Oral Hygiene During Invisalign Treatment

Because the aligners fit closely over the teeth, food debris and plaque should be removed before reinserting them.

Patients should:

Brush at least twice daily
Clean between the teeth
Clean the tongue
Attend dental check-ups
Attend professional cleaning when recommended
Reduce frequent sugary snacks and drinks
Report bleeding gums or tooth sensitivity
Avoid placing aligners over teeth that have not been cleaned after meals whenever practical

Removable aligners can make brushing and flossing more convenient than fixed appliances, but they do not prevent cavities or gum disease.

Good oral hygiene remains essential throughout treatment.

What Happens If an Aligner Is Lost or Damaged?

Contact the clinic rather than deciding independently which set to wear.

Depending on the treatment stage, the dentist may advise the patient to:

Continue wearing the current set
Return temporarily to the previous set
Move to the next set
Attend the clinic
Order a replacement
Receive a new scan

Do not continue wearing an aligner that is cracked, severely distorted or causing injury without contacting the clinic.

Keeping the previous set in its labelled package may be useful until the dentist confirms that it can be discarded.

What If the Aligner Does Not Fit?

An aligner that does not fit fully over one or more teeth may indicate that the teeth are not tracking as planned.

Possible reasons include:

Insufficient wear time
Changing sets too early
A lost attachment
An aligner that is not fully seated
A distorted aligner
Tooth movement differing from the simulation

Do not force a severely ill-fitting aligner into place.

Contact SWC Dental for advice. The dentist may recommend extended wear, seating exercises, attachment repair, a progress check or a new scan.

Invisalign vs Conventional Braces

Topic	Invisalign clear aligners	Conventional braces
Appearance	Transparent and generally discreet, although attachments or elastics may be visible	Brackets and wires are visible; ceramic options may be less noticeable
Appliance	Removable	Fixed to the teeth
Eating	Removed for eating, with fewer appliance-related food restrictions	Some hard or sticky foods may need to be avoided
Oral hygiene	Appliance can be removed for brushing and flossing	Cleaning around brackets and wires requires additional care
Cooperation	Requires consistent daily wear and responsible handling	Does not depend on remembering to reinsert the main appliance
Complex movements	Can treat many cases, sometimes with attachments, elastics or additional stages	May offer different mechanical control for selected movements and complex cases
Breakage	No broken brackets, but aligners can be lost, cracked or distorted	Brackets and wires may break or cause irritation
Comfort	No brackets or main archwire, but pressure and edge irritation can still occur	Initial soreness and irritation from brackets or wires may occur
Appointments	Monitoring is still required	Regular adjustment and monitoring are required
Treatment time	Depends on complexity, response and wear time	Depends on complexity, response and appliance mechanics
Cost	Depends on the individual plan and aligner package	Depends on the appliance, complexity and treatment duration

Neither option is universally better.

Invisalign may be preferable for a patient who values removability and discretion and can follow a strict wear routine.

Conventional braces may be more suitable where fixed appliance control is preferred, patient cooperation is uncertain or the orthodontic problem requires a different mechanical approach.

The appropriate choice should be based on diagnosis rather than appearance alone.

Invisalign and Digital Treatment Simulation

Digital planning allows the dentist to review a proposed sequence of tooth movements and communicate treatment goals to the patient.

The simulation can help explain:

Which teeth are planned to move
Where space may be created
Where attachments may be placed
How the bite may change
The proposed treatment stages

However, a simulation represents a planned outcome rather than a guaranteed prediction.

Teeth move through biological tissues, and actual movement may differ according to bone, roots, gum health, appliance fit and patient wear. Clinical monitoring and possible plan adjustments remain necessary.

Will Invisalign Change My Face or Jawline?

Orthodontic treatment can alter tooth position, lip support and the way the upper and lower teeth meet.

The visible effect depends on:

The original tooth position
The amount of crowding
Whether teeth are expanded, retracted or extracted
Jaw relationship
Growth in younger patients
Facial soft tissues
Treatment objectives

Invisalign should not be presented as a guaranteed method of creating a particular face shape or jawline.

Patients with a significant skeletal jaw discrepancy may need a different treatment plan. In selected cases, orthodontics may be coordinated with jaw surgery.

Can Invisalign Close Every Gap?

Clear aligners may close many types of spaces, but the cause of the gap must be assessed.

A space may be related to:

Tooth size
Missing teeth
Gum attachment
Tongue habits
Tooth inclination
Jaw size
Previous tooth movement
Gum and bone loss

Closing a gap without addressing the cause may increase the risk of reopening.

Some patients may need a combination of orthodontic movement and restorative treatment such as dental veneers or crowns to improve tooth proportions.

Can Invisalign Be Used with Missing Teeth or Dental Implants?

Invisalign may be possible when one or more teeth are missing, but the treatment must be planned around the intended replacement.

Orthodontic treatment may be used to:

Create suitable space for a dental implant
Close selected spaces
Upright teeth next to a missing-tooth area
Improve space for a dental bridge
Coordinate the bite before restorative treatment

A dental implant does not move like a natural tooth because it is integrated with the bone. Its position must therefore be considered carefully during planning.

In many cases, orthodontic movement is completed before the final implant restoration is placed.

Invisalign for Teenagers

Invisalign may be suitable for selected teenagers when:

Enough permanent teeth have erupted
The bite problem can be treated appropriately with aligners
The patient can manage the appliance responsibly
Oral hygiene is adequate
Parents and the patient understand the wear requirements
Growth and developing teeth have been evaluated

Treatment success depends on the teenager wearing the aligners as directed and keeping track of each set.

Clear aligners are not automatically easier than braces. They exchange fixed-appliance maintenance for the responsibility of consistent daily wear.

Invisalign for Adults

Adults may consider Invisalign for:

Crowding that was never previously treated
Teeth that shifted after braces
Gaps
Bite correction
Alignment before veneers, crowns or implants
A more discreet orthodontic option

Age alone does not prevent orthodontic tooth movement.

Adult planning may require additional attention to:

Gum health
Bone support
Missing teeth
Existing crowns or implants
Tooth wear
Previous root canal treatment
Temporomandibular joint symptoms

A coordinated treatment plan may be needed when orthodontics is combined with restorative or periodontal care.

Invisalign After Previous Braces

Teeth may shift after previous orthodontic treatment, particularly when retainers are not worn as advised.

Clear aligners may be used in selected relapse cases to realign the teeth. The dentist must still assess the complete bite rather than simply reproducing the appearance at the end of the previous treatment.

After realignment, a new retention plan will be required.

Frequently Asked Questions About Invisalign

Is Invisalign completely invisible?

No orthodontic appliance is completely invisible. Invisalign aligners are transparent and generally discreet, but they may be visible at close range. Tooth-coloured attachments, buttons or elastics can make the appliance more noticeable.

Can Invisalign treat severe crowding?

Clear aligners can be used for many levels of crowding, but suitability depends on the bite, available space, root position and treatment mechanics. Some cases require IPR, expansion, extraction, attachments, elastics or another orthodontic approach.

Do I need to wear Invisalign while sleeping?

Yes. Aligners are normally worn during both the day and night and removed mainly for eating, drinking beverages other than plain water and oral hygiene.

Can I drink coffee while wearing Invisalign?

It is generally advisable to remove the aligners before drinking coffee. Coffee can stain the appliance, and hot drinks may distort the material. Clean the teeth appropriately before reinserting the aligners.

Can I smoke or vape with Invisalign?

Smoking or vaping while wearing aligners may stain the appliance and affect oral health. Patients should discuss tobacco and nicotine use honestly with the dentist as part of treatment planning.

Do Invisalign attachments damage the teeth?

Attachments are bonded to the tooth surface and removed after they are no longer required. As with other bonded dental materials, careful placement, oral hygiene and professional removal are important. The individual condition of the enamel should be assessed before treatment.

Will I need teeth removed for Invisalign?

Not every Invisalign patient needs an extraction. The decision depends on crowding, facial profile, tooth position, bite and treatment goals. Other space-creation methods may be considered when appropriate.

Is Invisalign faster than braces?

Not necessarily. Treatment time depends on the orthodontic problem, planned movements, biological response and patient cooperation. Clear aligners should not be promoted as universally faster than braces.

Can I switch from braces to Invisalign?

It may be possible in selected cases, but changing appliances requires a new assessment and treatment plan. The dentist must evaluate the progress already achieved, remaining movements, bite and expected benefits of changing.

What happens after the last Invisalign aligner?

The dentist checks the tooth positions and bite. Additional aligners may be required if further movement is needed. When active treatment is complete, retainers are provided or planned to help reduce relapse.

How much does Invisalign cost?

The fee depends on treatment complexity, number of aligners, expected duration, diagnostic records and whether additional stages are required. An individual quotation can be provided after examination and treatment planning.

How often do I need to visit the clinic?

The review schedule varies according to treatment stage, aligner delivery system, oral health and progress. Even when several aligners are provided at once, professional monitoring remains necessary.

Invisalign^® clear aligners are custom-made for you.

The aligners are virtually invisible and fit snugly over your teeth. Each aligner shifts your teeth slightly, moving them horizontally and vertically and even rotating them when needed.

Your aligners are engineered to use the right amount of force in the right place at the right time. When you change to the next set of aligners (typically every week) your teeth gradually move into position, following a custom treatment plan mapped out by your doctor.

How to live with clear aligner

Keep eating all your favorite foods.
Stay active in all the sports and activities you love.
Keep brushing and flossing just as you normally do, with no brackets or wires to get in the way.
You’ll experience fewer emergency visits, without the hassle of brackets and wires breaking.
Your Invisalign clear aligners are virtually invisible, so people may not even notice you’re wearing them.

Wearing your aligners

You’ll be ready for anything, from movie night to coffee with friends. Just take your aligners out to eat and drink, then brush your teeth before putting them back in.
Wear your Invisalign clear aligners 20 to 22 hours a day for best results.
Parents, your teen’s aligners will have blue compliance indicators to assure you they’re wearing them enough.
