Hi:Unless there is over preparation of the tooth, normally there is no nerve damage. Its best to do a nerve test on the teeth to be prepared for veneers to make sure there is no damage before work is started. Additionally an expert cosmetic dentist will make sure there is no over preparation in order to avoid any nerve exposure or damage.Best,Dr. Maddahi
Veneers, if done carefully, should not cause a tooth to die. Also, a dead tooth only needs a root canal. Dentures are a very big stretch from veneers. Find a dentist who has experience doing veneers and ask to say before and after pictures.
