My new veneers are falling off! In 3 months, 3 out of 6 have fallen off. (Photo)

Hello Cali Girl,Sorry to hear this is happening, but there could be one of three possible senerioes:1)  The dentist could have done everything completely right, but the glue or cement used could be faulty.  This is rare, but it can happen.  The dentist may want to consider using a different glue or cement.2)  The dentist may need to adjust the prep to make it more able to hold the veneer more securely.3)  The veneer itself may need to be adjusted to prevent improper contact with other teeth that may be causing the veneer to become dislodged.  Good luck and I hope this info helps you.

Several reasons why a veneer can fall off:1. The bite--- you have a very "tight" bite, or grind your teeth, producing a large amount of force that exceeds the bonding to the ceramic. The opposing (lower) teeth can be adjusted, or orthodontic treatment can be initiated.2. The amount of tooth structure left--- There appears to be ALOT of room between your tooth preparation and the incisal edge of your teeth, meaning a lot of unsupported porcelain that needs to be bonded. Think of it as a teeter-totter: Too much on one side causes imbalance. If there is too much unsupported porcelain, a 360 degree veneer (Known as a crown) can be made to better bond to the tooth.  3. Bonding technique--- The clue is in the glue!!! Was proper curing time allowed during cementation? Cord placed around the gum to isolate the tooth from the gingival fluid/saliva/blood?? Was the veneer etched? Steamed? SIlanated? and bonded properly?4. The veneer itself does not fit--- laboratory error (too much die spacer, poor impression, technician error), can lead to a misfit of the veneer clinically. Was the veneer tried in? If so, how was the veneer and the tooth cleaned off prior to cementation? Multiple attempts at cementation can ruin the micro surface.As with all information on the internet, check with your local dentist prior to selecting any Treatment....Hope that helps!

Thanks for posting the pictures. There are several things that can cause veneers to fall out. One question I have is it always the same veneer? If it is the same veneer there may be an issue with the way your teeth are fitting together. If you are hitting on this tooth too heavily the veneer can pop off. Additionally, there seems to be very little tooth left on which to bond the veneer. This could be the problem. If multiple teeth have popped off it may still be a bite issue, but another option is the bonding protocol. If the bonding technique is sloppy the veneers have a greater chance of coming off. Lastly, the teeth may be over prepared, leaving little or no enamel to bond to. Changing the veneers into crowns of the same material may give you more stability. From looking at your picture it is difficult to determine what exactly the problem is. I hope this information helps.
