Is There Any New Treatments for Enamel Peeling off of Teeth?

Unfortunately we do not have any methods of stimulating new growth of enamel when it is worn off.  You can try and repair the damage by having your dentist use some bonding. 

Unfortunately enamel does not regrow, It is important that you go to a good hygienist, some hygienist especially in high volume dental clinic do not do the cleaning appropriately and can cause you to lose enamel, I am not saying this is the case but just keep this in mind.
