Is there a way to rebuild the enamel on your teeth?

Question

my boyfriend said that he heard something about when your teeth get so thin, that you could rebuild your enamel. now, as far as i know, you can't rebuild the enamel on your teeth. so what's up with that?

Answer 1

some mouth wash and toothpaste claim to do this, but I highly doubt it works.  

Answer 2

Best answered by a dentist of course.  The answer is once it's totally gone you're pretty much screwed.

You probably will be buying caps, or false teeth.

Answer 3

brush

Answer 4

I heard of some mouth wash and toothpaste that can help rebuild the enamel on your teeth.

Who knows if it works though
