Sometimes, bonding also is used to protect a portion of the tooth's root that has been exposed when gums recede.
Your dentist will then apply the resin in layers. Each layer will be completely hardened (cured) by an ultraviolet light or laser before the next one is applied. Different colors also can be layered to more closely match your natural tooth shade.
Once the bonding material is hard, your dentist will further trim and shape it. Then he or she will polish it to match the sheen of the rest of the tooth.
The procedure usually takes about 30 minutes to an hour. If you're having more than one tooth done, you may need a longer appointment or several visits.
At any time, call your dentist if the bonding chips or if pieces fall out.
