What would make someone not a candidate for veneers?

Hello there,I have used veneers to transform the size, shade and shape of patient's smiles for over a decade. Despite your past, they may be a great option for you.  Veneers are not recommended for any of the following: poor oral hygiene, insufficent tooth structure or missing or broken teeth.  I would recommend consulting a cosmetic dentist to determine your options. Always look at before and after photos when selecting your dentist. They will give you an idea about what you can expect. Good luck and I hope this helps.

If your teeth are moderately - severely crowded or misaligned or if there is poor remaining tooth structure, veneers would not be possible.

As long as the the tooth is stable you should be a fine candidate. If your teeth are too broken down for veneers you may need a crown instead.
