How Does a Dentist Adhere Invisalign Buttons to Teeth?

Similar to bonding brackets for wire ortho or bonding in fillings, the buttons are done in the same fashion.  Resin used for fillings are used as buttons and are tooth colored.  When removed, the teeth get polished and cleaned, so if any staining happens it is minimal.  The same risk exists for the brackets for traditional ortho, but the buttons are easier to clean.

I personally have not witnessed any staining.

Invisalign attatchments are totally tooth colored and made out of the same material used in white fillings.  They are placed on the outside of the tooth and do not dmage the tooth at all .  When completed with the Invisalign treatment, they are simply removed by gently shaving them off and polishing the tooth.  The staining risk is no different then when placing a white filling which is minimal with current composite (white) filling materials.  The danger with staining the tooth from traditional brackets comes from the difficulty cleaning around them for the patient whereas with Invisalin the trays are removed daily for easy cleaning.

The buttons are bonded very similar to the way fillings are placed or brackets are bonded on your teeth.  An acid etch is applies to your teeth, followed by a bonding agent and then a composite resin is used for the buttons.  To remove them they are simply buffed off and polished.  If they do stain they can easily be smoothed to remove any of the staining.
