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

There are several good veneer glues but other issues may be involved
There are several reasons why this may be happening. The bite, the amount of enamel left on your teeth, the glue (bonding cement), the bonding technique of the doctor, etc.....
So if your bite has been checked and you wear a night guard then we can probably discard this. I'm going to assume you have a full complement of teeth in the back molars and are not putting added pressure to the fronts.
The are two cements I use with good success: 1) Variolink II by Ivoclar and 2) Rely-X Veneer cement by 3M. I know Kerr has good dental products so I'm not sure it is the company (I guess you could have a bad batch of cement or could be expired).
If your teeth do not have an adequate amount of good enamel to bond to, then you may be better off with full crowns. Venees get their bond strength from enamel.
Good bonding technique is crucial. You can do a whole day lecture on this. But basically, you must follow all the steps with no shorcuts and you must keep the veneer and tooth isolated and free of saliva or water contamination during the process.
Also, the lab has to use the correct porcelain and prepare it properly to bond it. It must be etched with hydrofluoric acid and the doctor has to silane it. Some doctors choose to etch it at the office.
Veneers popping off
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 veneer
2. If you wear your nightguard you still may be clenching or grinding during the day. The bite (occlusion) must be evaluated and addressed properly
3. 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.

Really has nothing to do with the glue. Sounds like a bond failure

In a recent study veneers had a 99% 10 year success rate when the preparation is totally in enamel and the veneer is bonded to enamel. The success rate drops dramatically when the preparation is extended into dentin. It is my opinion that dentin bonding does not work over the long term. I have seen thousands of situations where it breaks down over time. If your preparations are into dentin, then the best solution is probably to replace the veneers and do "360 veneers" extending all of the way around the back. No bonding adhesive will work if the biomechanical principals are flawed.
the first thing i do is look at the veneer that is off. Is the residual bonding agent on the veneer? Is is on the tooth? This will usually give you insight where the problem lies. the cement on the veneer means the tooth was not adequately prepared and the amount of dentin was too great, the moisture content was not ideal, or the bonding agent was applied incorrectly to the tooth. If the "glue" is on the tooth then the porcelain was not etched enough or too much, the surface did not get the right amount of silane to chemically activate the porcelain for get a good chemical bond to the resin. Light could be an issue if the veneers are too thick (which yo0u should have probably gotten a 3/4 crown prep design or crown prep for better retention) it does not polymerize the resin completely so a dual cure cement is needed. Their are many issues to consider and most of the companies make really good resin bonding agents so to blame a "glue" is an inadequate excuse in my opinion
Veneers coming off
When veneers come off it is generally due to the way they are bonded, what is left of the tooth beneath, or the way your teeth fit together. The brand of cement is not usually a factor. The cementation process is very specific and if there is a problem, this can happen, but I'm willing to bet it has more to do with the bite than the cement. A second opinion may be a good idea.
Veneers popping off 1 by 1, what is causing this
Sorry to hear about the issues that you are having. There are several reasons why this may be happening. First you said that they have checked your bite,if your bite is off it can cause this problem, you said it is not we can eliminate that. Another is the amount of enamel left on your teeth, the bonding system used, and the bonding technique of the doctor. I have not heard about the kerr product used. If it continues I would seek a second opinion.
