What Are Invisalign Attachments and Why Might You Need Them?
Invisalign attachments are small, tooth-coloured shapes bonded to selected teeth to help clear aligners apply force in the direction required for specific tooth movements. Not everyone needs them, and the number and position of attachments depend on how the teeth need to move.
At BestSmile Dental Clinic, our team supports patients through clear aligner assessment, digital planning and ongoing monitoring based on their tooth alignment and bite. When attachments are needed, they become part of a personalised treatment approach rather than something every Invisalign patient automatically receives.
What Are Invisalign Attachments?
Invisalign attachments are small, tooth-coloured shapes bonded to selected teeth. Although patients may sometimes casually refer to them as “buttons”, their role is to provide additional contact points between the teeth and aligners.
The aligners are designed to fit around these attachments. Depending on the required tooth movements, SmartForce™ Attachments may be positioned on certain teeth to help the aligners work as intended.
Why Might You Need Invisalign Attachments?
Attachments can give an aligner additional contact with a tooth when extra support is required for a particular movement.
They may be used to help with:
- Rotating certain teeth.
- Moving selected teeth towards their intended positions.
- Helping an aligner maintain appropriate contact with particular teeth.
- Supporting more controlled tooth movement during treatment.
Whether you need attachments depends on your teeth, bite and the movements required as part of your treatment. This is assessed individually rather than assuming attachments are necessary for every clear aligner patient.
How Do Invisalign Attachments Work With Your Aligners?
Attachments work together with the shape of your aligners to support specific tooth movements. The process generally involves four stages.
- 1
Assessment of Your Teeth and Bite
Treatment starts by assessing your tooth alignment, bite and individual needs to determine whether clear aligners may be suitable and which movements need to be planned.
- 2
Digital Treatment Planning
Digital tools help capture detailed information about your teeth and support three-dimensional treatment planning. At our clinic, iTero scanning and ClinCheck® can help visualise the intended sequence of tooth movements.
You can learn more about clear aligners with iTero digital scanning and how digital impressions can support clear aligner treatment.

Attachment Placement Where Needed
If attachments are part of the treatment plan, small tooth-coloured shapes are bonded to selected teeth. Their shape, size and location can vary depending on the movements they are intended to support.

Your Aligners Fit Around the Attachments
The aligners are designed to interact with these contact points. As you progress through the prescribed aligner sequence, this interaction helps apply forces in the directions established during treatment planning.
What Do Invisalign Attachments Look and Feel Like?
Invisalign attachments are tooth-coloured and relatively discreet, but they are not completely invisible. Their visibility can vary depending on their size, position, tooth colour and location in your smile.
You may also notice the attachments with your tongue, particularly when your aligners are removed.
A few practical things to know include:
- Attachments are bonded directly to selected teeth.
- Your aligners are designed to fit over and around them.
- Their number and position vary between patients.
- They can be professionally removed when they are no longer required.
Invisalign Attachments vs Invisalign Without Attachments
Both approaches can be part of clear aligner treatment. The main difference is whether additional bonded contact points are needed to support the required movements.
| Comparison | With Attachments | Without Attachments |
|---|---|---|
| What is on the teeth? | Small tooth-coloured shapes on selected teeth | No attachments on those teeth |
| Purpose | Provide additional contact points for certain movements | Aligners act directly around the teeth |
| When might this apply? | When additional contact points are useful for planned movements | When the planned movements do not require attachments |
| How is it decided? | Based on assessment and treatment requirements | Based on assessment and treatment requirements |
Treatment without attachments is not automatically better. What matters is choosing an approach that suits the movements required for your teeth and bite.
What Happens to the Attachments During Treatment?
Attachments may remain on selected teeth while you progress through the relevant stages of treatment. Our team monitors your progress during scheduled reviews and determines whether any changes are needed.
Attachment placement → aligner wear → monitoring → adjustments if required → completion → attachment removal → retention

Do Attachments Change How You Care for Your Teeth?
Attachments add small contours to the tooth surface, so maintaining good oral hygiene remains important.
During treatment, practical care may include:
- Brushing carefully around attachments and along the gumline.
- Keeping your teeth and aligners clean according to professional guidance.
- Following instructions when removing and reinserting aligners.
- Attending scheduled reviews so treatment progress can be monitored.
- Contacting our dental team if an attachment becomes loose or comes off rather than attempting to repair it at home.
How Does Our Team Plan Clear Aligner Treatment?
Our approach combines professional assessment with digital planning to understand your treatment needs, determine whether attachments may be useful and guide ongoing monitoring.
Professional assessment → iTero digital scanning → ClinCheck® 3D planning → personalised tooth-movement planning → SmartForce™ Attachments where needed → aligner wear → monitoring → retention
Digital technology supports professional judgement rather than replacing it. If you are considering orthodontic treatment, you can explore our clear aligner treatment in Penang to learn more about the assessment and treatment process.

No. Some patients need attachments on selected teeth, while others may require fewer or none. Their use depends on the tooth movements required.
They are tooth-coloured and designed to be relatively discreet, but they are not necessarily invisible. Visibility varies according to their size, location and the colour and position of the tooth.
Not always. How long they remain on the teeth depends on when they are required during the course of treatment.
Contact our dental team for advice. Avoid trying to repair or rebond the attachment yourself because its position and shape are determined as part of your treatment.
Attachments can be professionally removed once they are no longer needed. Our dental team will determine the appropriate timing based on treatment progress.
