“How long do porcelain veneers last?”

many , many years with not much care.

They don’t have a particular life span. It usually depends on how well the veneers were prepared, the lab that was used, the type of porcelain, and the patient. Veneers are made very thin so most labs will advise that the life span for porcelain is 5 years. However, I have see 20-30 year old veneers in patients mouths. It’s important to understand veneers are like having thin glass over your teeth, if you are grinder, clencher or use your front teeth to open packages, bite your nails, chew ice etc. you will probably fracture or break your veneers and require a new one. Also understand that it is extremely hard to match shades of 1 veneer. So sometimes I change additional veneers to get the color to match.
