If you lose your tooth enamel on permanent teeth, is the enamel permanently gone? Does it come back? How ifso?

Hello...The answer is :No" the enamel doesn't grow back. Once it's gone....it's gone..Your dentist can have Porcelain Veneers created to fit over the front of the tooth or Porcelain Crowns that cover the entire tooth ...In any event the Crown or Veneers can not only help keep your teeth they can give you that popular Hollywood smile. Good luck and I wish you well.
