Surry Hills Invisalign Guide: Buttons, Attachments & Filing Explained
Quick Answer: What Are Invisalign Buttons, Attachments, and Filing For
Invisalign buttons (attachments) are small, tooth-coloured resin bumps bonded to certain teeth so your aligners have something to grip onto for precise movements like rotating or tipping. Filing (IPR) gently creates tiny amounts of space between crowded teeth using digital-guided, painless polishing. Not every patient needs either; your dentist adds them only where they'll meaningfully improve your results.
What is the purpose of the button on Invisalign?
These aren’t just dental bling. Though some people lovingly call them little diamantes, they’re actually made from a tooth-coloured resin (same stuff we use for fillings).
We glue them onto specific teeth to act like handles. Why?
Because your teeth are smooth. And so are your aligners. So if you try to push smooth plastic onto smooth enamel, there’s a lot of slippage and not a lot of grippage (and the movements we can do are very limited).
The purpose of the buttons on Invisalign is to act like handles, giving your aligners something to grip onto so they can apply pressure in the right direction.
These attachments come in all shapes and sizes and help us:
Rotate stubborn teeth
Nudge some teeth up (intrusion) or down (extrusion)
Apply sideway force like torque or tip
Keep your aligners seated properly
They’re painless to place, totally temporary, and polished off at the end. Like they were never there.
Is Filing (IPR) Necessary to Create Space Between My Teeth?
Filing is kind of like flossing… with sandpaper.
We do this when your teeth are a bit too crowded — think: not enough real estate, so we have to find or create space. Traditionally, we would pull teeth out, but thanks to digital technology, we can more precisely calculate how much space is needed, and where we can ‘gain’ that space from; we rarely have to pull teeth out nowadays. Instead, we gently polish 0.1–0.25mm between select teeth to create space.
If you’ve ever filed your nails, it feels kinda like that. No nerve endings in enamel = no pain. Just a weird noise and a weird feeling.
We do this conservatively and only when needed. But it makes a massive difference in how well your teeth can move into alignment, without extracting anything.

Frequently Asked Questions
Do Invisalign buttons hurt to remove?
No, removing Invisalign buttons (attachments) is quick and painless. Your dentist gently polishes the tooth-coloured resin off at the end of treatment, leaving no mark or damage to your enamel; it's like they were never there.
Will people notice my Invisalign attachments or buttons?
Not usually; attachments are made from tooth-coloured resin and designed to blend in with your natural teeth. They're small and subtle enough that most people don't notice them in everyday conversation, though they may be slightly visible up close.
Does IPR (interproximal reduction) weaken or damage my teeth?
No, IPR is a conservative procedure that removes a tiny amount of enamel (0.1–0.25mm) between select teeth, well within safe limits. Since enamel has no nerve endings, the process is painless, and it's carefully calculated using digital technology to avoid weakening your teeth or their long-term health.
How many teeth typically need buttons or attachments?
This varies from patient to patient depending on which movements your treatment plan requires, such as rotating, tipping, or extruding specific teeth. Some patients need attachments on just a few teeth, while others need more; your dentist will map this out as part of your personalised Invisalign plan.
Can I remove Invisalign attachments myself?
No, attachments should only be removed by your dentist using a special polishing tool designed for the tooth-coloured resin. Trying to remove them yourself could damage your tooth enamel. If an attachment feels loose or falls off between visits, contact your dentist rather than removing others yourself.
Does every Invisalign patient need attachments or filing?
No, not every patient needs attachments or IPR; it depends on the specific movements and spacing your teeth require. Your dentist will only add these where they make a meaningful difference to your results, and many straightforward cases don't need either.
