I have had 6 veneers put on and 1 by 1 they are popping off!!! My bite has been checked and rechecked. Also, I wear a night guard EVERY night. My dentist, who is as frustrated as I am, used Kerr glue brand, but I was wondering if there is a better success rate with a different brand. Please help me,,,,,It's embarrassing losing a veneer in public. Thanks!
Answer
Veneers coming off or popping off is due to lack of enamel on your teeth. Veneers are not cemented but needs to be bonded, the porcelain crowns can be cemented but not veneers. If you do not have enough enamel and the veneer is only on dentin, the popping off veneers are common, in which you need to have porcelain crowns.

I have heard of this type of thing happening before and 9 times out of 10, it is the glue. Most dentists use a different glue for all porcelain/emax/zirconia veneers, but what I find is that the same glue that the same cement that your dentist has used for years on gold crowns, will work perfectly on porcelain and zirconia veneers. I recommend that he try one of his other glues. I hope this helps.Follow me if you have more questions.Sarah Thompson, DMD

The "glue" I use is Insure by Cosmedent. I rarely have veneers come off. I have had patients that I have placed veneers 15 to 20 years without a problem. It is not the veneer but the doctor who places them that is the weakest part of the process. If the doctor is not trained properly or does not take the time to learn how to prepare and place veneers, they will usually not last as long as with a doctor who has the training and experience.

There is not 1 simple answer to this question and many variables need to be addressed.1. The amount of enamel that remains on your tooth after porcelain veneer preparation. Only a skilled cosmetic dentist can answer and address this. Sometimes when all other factors are addressed, it may be necessary to do a conservative porcelain crown instead of a veneer2. If you wear your nightguard you still may be clenching or grinding during the day. The bite (occlusion) must be evaluated and addressed properly3. When the veneers come off and are rebonded, it is often difficult to completely remove all the old adhesive from the inside of the veneer and the tooth. This must be done to insure proper rebonding. As well as chemically treat the inside of the veneer again with a porcelain etchant, and etch and prime the remaining tooth structure with the proper solutions.Steven M. Goldy, DDS
Answer
This could be a number of things. Kerr is a reputable company. Honestly, most bonded adhesive cements are pretty comparable, so it's probably not the cement. Could be a bond failure with the first layer of adhesive called the "bonding agent." This basically turns something organic (like a tooth) into a hybridized system that can be bonded to (cement). The bonding process - before the cement - is the most technique-sensitive portion.
