Why are my porcelain veneers cracking?

Thursday, December 11th, 2008

How long should porcelain veneers last? Is there any type of warranty? What are reasons they would crack and what can you do if they are cracking independently but all with in one year’s time?

If you can give me any answers or a clue on what I can do I would greatly appreciate it.

Thank you,

Sherri,
There is no set lifespan on porcelain veneers. They should last for a number of years. Some last as long as twenty years. But dentists typically don’t put a warranty on them because so much depends on how well you take care of them.

If you have a number of them that are cracking within a year’s time, I would suspect that they weren’t bonded properly. Since porcelain veneers are fairly thin, they are also fairly fragile. They get their strength from bonding to the tooth. When properly bonded, they are quite strong and will resist all normal forces that occur in the mouth.

If you are having them crack within a year of putting them on, it would be reasonable for the dentist to replace the cracked veneers for no charge. This isn’t normal wear and tear–this is a flaw in the bonding process.
