you want to replace dentin at a faster rate than it decays?

you have 3 methods artificially, speed up the production of your teeth, change the rate of abrasion or make the tooth harder.

or you could scratch that.

and

make your teeth soft, so they are easier to wear down. then get the teeth to grow faster.

teeth grow from the root up/down.

you cannot make anything adhere to the surface of the tooth, which becomes integral, there is no such thing as re-enameling.
