New Study Confirms That Veneers Last a Long time
Boutique Dentistry for Nashville, Tennessee
Cosmetic dentistry is a significant investment, and if you’re going to make that investment, you want to know that it’s worth it. One concern many people have about tooth veneers is how long they are going to last. While veneers can make your smile beautiful, they might not be worth the investment if they aren’t going to last very long. Partly, the concern arises from veneers being called “porcelain veneers,” which can make them seem fragile. Although the name is partly historical, the idea persists, so it’s worth taking time to go over the results of clinical studies showing just how long-lasting veneers are. A study recently published in the Journal of Prosthetic Dentistry shows that veneers can be very long-lasting, with high survival rates through the 14 years of the study.
A Small Long-Term Study
In this study, researchers looked back at over 100 veneers that had been placed at a single practice between 7 and 14 years before. These veneers are not technically porcelain–they are high-leucite ceramic, a type of material that was in very common use in the early 21st century.
Initially, the researchers tried to recruit 60 patients who had veneers placed at least seven years before. Patients were offered free treatment in exchange for their participation in the study, but only 26 responded that they wanted to participate.
These participants were invited into the office and their veneers were examined and graded, using an aesthetic scale common in dentistry, dividing veneers into alfa, bravo, charlie, and delta classes.
Of the total of 114 veneers, 109 were clinically acceptable, an overall survival rate of 96%. From the failure times, researchers calculated a 7-year survival rate of 98% and a 14-year survival rate of 88%. Of the five that had failed, four had fractured, and one was replaced with a dental crown to help support a removable partial denture. Although all the failures were in the upper (maxillary) arch, the failure rate was statistically indistinguishable for the two arches. Three of the fractures occurred in the same person, and the authors attributed this to bruxism and other parafunctions that can damage veneers.
Of the surviving veneers, most were rated Alfa overall, but there were some problems with the veneers. The biggest problem was margin integrity, where 65% of veneers were rated bravo, partly because the explorer caught at the edge and partly because of slight marginal discoloration.
Several of the veneers that were considered successful had minor chips, and some developed craze lines (small vertical cracks, which can also appear in tooth enamel).
Long-Lasting Cosmetic Dentistry
If you’re interested in transforming your smile, veneers are a great choice. They can look natural, preserve much of your natural tooth enamel, and can give dramatic transformation. Plus, as this study shows, they can last a long time, especially if you are not a bruxer and avoid parafunctions like chewing on nonfoods like fingernails or pen caps.
You can also extend the life of your veneers by working with a skilled cosmetic dentist like Dr. Kent E. White in Nashville. He has the training and experience necessary to properly place veneers as well as manage bite issues. The use of newer materials can also lead to longer-lasting veneers.
