Can a Veneer fall off and then not be able to put back on?

This can happen after a number of years, but is extremely rare.  The bonding techniques and agents used today allow for an extremely high bond strength of the porcelain to enamel.  Be sure to choose a dentist very experienced in treating veneer cases and you should finish with a case that is both gorgeous and durable.  Good luck.  

Hello there,I would highly recommend that you find an excellent cosmetic dentist that can place your veneers and also offer you a warranty.  I usually offer a 10 year warranty for patients like you.  It is very rare that a veneer will fall off and when it does, there is usually a good reason for it.  Find a doctor that has plenty of real before and after pictures of patients' teeth that show exactly what the dentist is capable of.  Good luck and I hope this info helps you.

Hi! In short, yes it is possible to recement veneers.  If you have the whole piece and it can be seated back on the tooth without any interference, veneers can be recemented.  If you start to see several veneers falling out, that may raise a concern and would probably be worried that more will continue to come off.  This usually will happen if there was contamination of the cement during cementation, insufficient conditioning of the veneers and/ or tooth, as well as not curing the cement long enough.  If you do get a veneer to fall out, I would suggest going to your previous dentist who placed the veneers to make sure the same cement is used as using a different cement may affect the overall color of the veneer.  Remember, veneers are very thin shells of porcelain so cement will impact the final color of veneers.  If the veneer happens to fracture, there is a chance that you may be able to recement, depending how the veneer is fractured, otherwise you will need to make a new one.
