Failed Veneers


Veneers can fail due to many things. But the good thing is most times these veneers can be fixed. Some veneers appear and feel too thick. This is because the dentist did not remove enough tooth structure or the lab made the veneers too large (over bulked). This happens a lot with a few brands of veneers claiming you can have very minimal or no prep at all done. However, they are often too thick and fall off due to poor quality bond to the existing tooth. Some veneers appear to long, forming “bunny teeth” or “piano keys”. Sometimes veneers will have no shine or lack luster, this means the dentist or lab did not properly finish the veneers before they placed them.


A lot of patients come to our office with veneers that are constantly falling off. This is not normal; it could be that your bite is off or that the veneers were not properly bonded to the teeth. This does not necessarily mean your dentist used a poor quality bonding agent. Bonding tooth to porcelain is a very delicate procedure that could be tainted by saliva, blood, or water. And if not dried properly before insertion, this could happen. Unsightly dark marks around the margins of veneers could mean decay is multiplying rapidly underneath these restorations. This could also be because of a poor bond with open areas where decay can seep in.


Also, color error is a big red flag that your veneers could have been done much better. With all the advances in dental technology, you should be unable to detect the difference in the color of a veneer and a natural tooth. If you are having sensitivity in your veneers this could be a sign that the veneer did not adhere properly to the tooth, allowing for air and debris to work its way inside. You should feel no sensitivity, and the veneer should look flawless and flush against the tooth structure. Always ask to see before and after photos of the cases your dentist has completed. If you are unhappy with the results or your dentist cannot come up with any photos, you may want to reconsider the procedure being done there. 


Some dentists might not have gone to special training courses for the correct placement of veneers. Just because a dentist is licensed does not mean they know how to correctly fabricate veneers and bond them to teeth. One of the most important things in dentistry is to constantly attend continuing education seminars. New and better products and techniques are always arising, and by always learning about them Dr. Koeppel is able to fix poor quality dentistry and give his patients world class care.
