How to Repair Tooth Veneers

Updated February 21, 2017

Tooth veneers (almost always porcelain) are used by dentists to cover discoloured or chipped front teeth. Sometimes the dentist will use veneers on several teeth to close small gaps and spaces because using veneers is less expensive than using crowns. To place the veneer, the dentist shaves the front surface of the tooth and glues the veneer on in a way similar to the way you would glue on a false fingernail. Repairs involving veneers usually involve a small fracture in the veneer or regluing the veneer to the tooth. You can repair the veneer yourself with porcelain etch and silane, available from your dentist, a dental lab or an online lab.

Pour distilled water into a small bowl, and place the veneer in the bowl. Use your fingers to gently clean and pull the remaining glue off the veneer. Be careful not to tear the veneer if it has a fracture in it.

Lay out a clean towel to work on, and set the veneer on the towel.

Brush porcelain etch onto the inside surface of the veneer with the small brush included with the etch. Brush up and down across the entire veneer to create a rough surface, which is what will allow the porcelain silane adhesive to adhere better. Allow the etch to dry for 10 minutes.

Brush porcelain silane onto the inside surface of the veneer with the brush included with the silane. Brush in a side-to-side motion across the entire veneer.

Place the veneer back on your tooth carefully, easing it slightly under your gum. If the veneer is factured, squeeze the two sides together after the veneer is on your tooth to close the fracture.

Hold the veneer on the tooth with your fingers for a minimum of three minutes. Wait four hours before eating to ensure the veneer has bonded securely to the tooth.


You can purchase veneer bonding kits from some dental labs that include the porcelain etch together with the porcelain silane and directions on how to use each.
