Veneer Debonding or Chipping: Response, Redo, and Warranty

Why debonding or chipping happens

Given how veneers are bonded and the material used, strong impact, biting hard foods, or teeth grinding can cause a veneer to come off or chip. Occasionally, factors related to the bonding process or tooth surface condition can also play a role. Causes vary case by case and can only be confirmed through a dental exam.

What to do immediately

• Keep the detached or broken piece and bring it to your appointment
• Contact the treating clinic, or a nearby dentist, as soon as possible
• Avoid biting on the affected area and avoid very hot or cold foods to reduce irritation
• Mention any pain, bleeding, or sharp edges when you report the issue

What not to do

• Don't try to reattach it yourself with super glue or similar adhesives
• Don't try to file down a sharp edge yourself with tools
• Don't delay a visit just because it looks okay — appearance and actual tooth condition can differ

What to check in a warranty policy

If you were given a warranty policy before treatment, it's worth checking the coverage period, what situations are included (e.g. debonding during normal use vs. external impact), how redo costs are handled, and whether it only applies at the original clinic. Warranty terms vary by clinic, and this page does not state specific terms or amounts.

The redo process

01

Assessment

The dentist examines the affected area and surrounding teeth and gums.

02

Cause review

Possible causes such as impact, habits, or bonding condition are reviewed together.

03

Rescan or reuse existing data

A new scan may be taken, or existing design data referenced, to plan a new shell.

04

Fabrication and rebonding

The lab fabricates a new shell, which the clinic then bonds in place.
