That is difficult is to say. It depends greatly on the individual; more specifically how good their oral care is, if they are a grinder/clencher, and what condition their tooth was in when placed. I highlighted the last one because the research is very clear that if the veneer can stay only in enamel, the outer layer of tooth structure, it will hold up EXTREMELY well. The less enamel there is left after preparing for the veneer, the worse the prognosis is. This is why if there is not a lot of enamel left, I still call the procedure a “veneer” but will wrap it around the back and do a 3/4 crown or some variance of that.
The meta-analysis has the 5 and 10 year survival rate at about 95% on IDEAL
situations. Here is the conclusion of that study (Watt 2013)
“When bonded to enamel substrate, feldspathic porcelain veneers have a very high 10-year survival rate that may approach 95%. Clinical heterogeneity is associated with differences in reported
survival rates. Use of clinically relevant survival definitions and careful reporting of tooth characteristics, censorship, clustering, and precise results in future research would improve meta-analytic estimates and aid treatment decisions.”
Gurel 2013 Influence of enamel preservation on failure rates of porcelain laminate veneers
shows that veneers bonded to ONLY dentin and teeth with preparation margins in dentin are approximately 10 times
more likely to fail than veneers bonded to enamel. Also coronal crown lengthening increased the risk of veneer failure by 2.3 times
The reality is the majority of esthetic restorative cases I do that get veneers already have some fillings or are in a position that they are not totally in enamel. To prep only in enamel is basically the dream veneer case, which rarely exists on older people wanting a smile makeover.
So, how long do dental veneers last? It depends! On you and your habits, your tooth condition, and how good your dentist is.
