What is the Name of the Glue Used on Porcelain Veneers That Have Stayed On?

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.
