Invisalign attachments: what those tooth-colored bumps are
Invisalign attachments are small composite bumps bonded to your teeth to help your aligners grip and move them. They're a planned part of treatment and will be removed when you're done.

What are Invisalign attachments?
Invisalign attachments are small bumps made of tooth-colored composite material that your orthodontist bonds directly to specific teeth. They look a bit like tiny handles and sit on the front surface of your teeth.
They’re not a sign of a problem or a mistake. Instead, they’re a planned part of your treatment. Your orthodontist chooses which teeth need attachments based on the movements required to straighten your smile.
Why does your treatment need them?
Your Invisalign aligner is smooth plastic. Without something for it to grip, the aligner can slide around or not apply force where it’s needed. Attachments give the aligner anchor points so it can pull, rotate, or tip each tooth with the right amount of pressure in the right direction.
Different teeth may need attachments of different shapes or sizes, depending on how much movement is planned. Your orthodontist designs this as part of your overall treatment plan.
How are attachments placed?
Attachment placement happens during a visit to your orthodontist. The tooth surface is lightly cleaned and prepared, then the composite material is bonded on using a tooth-colored resin and a special light. The process is quick and painless — you won’t feel anything beyond the pressure of the instruments.
Day-to-day care and what to avoid
Your attachments are durable, but they’re still composite material bonded to your tooth. A few habits can help them last:
Avoid chewing on hard or sticky foods. Ice, hard candy, and sticky caramel can stress the attachment and cause it to chip or pop off. This is especially important while wearing your aligner, which already puts gentle pressure on the tooth.
Be gentle when removing your aligner. Use your fingers to pop the aligner from a corner of your mouth rather than biting or using fingernails at an attachment. Rough removal can dislodge a weakened attachment.
Keep up with your oral hygiene. Brush gently around attachments and floss normally. Food and plaque can accumulate around them if you’re not careful, so regular cleaning helps protect both your teeth and the attachments.
What if an attachment breaks or comes off?
If you notice an attachment is cracked, missing, or loose, contact your orthodontist right away. A missing attachment means that tooth won’t receive the pressure it’s supposed to, which can throw off your treatment timeline. Your orthodontist can usually re-bond it quickly, or they may recommend other adjustments to keep your treatment on track.
If you’re worried about damaging an attachment, that’s worth discussing with your orthodontist — they can give you specific dos and don’ts based on your individual treatment.
What happens when treatment is done?
When you’ve reached your orthodontist’s goals and you’re done wearing aligners, the attachments are removed. Your orthodontist will gently clean off the composite material and polish your tooth back to its natural shine. There’s no lasting mark or damage — your tooth returns to its original surface.

Frequently asked questions
Are attachments a sign something went wrong with my treatment?
No. Attachments are a normal, planned part of many Invisalign cases. Your orthodontist places them at the start of treatment so your aligners have something to grip and apply force to specific teeth. They're temporary and will be removed when treatment is complete.
What should I do if an attachment comes off?
Contact your orthodontist as soon as possible. A missing attachment can slow your progress because that tooth won't receive the right pressure from the aligner. Your orthodontist can re-bond it or advise you on next steps.
Will attachments damage my teeth?
No. Attachments are bonded to the outer surface of your tooth and are removed after treatment without lasting damage. Your orthodontist will clean and polish the area where the attachment was.
