When you say you can't regrow enamel but can remineralize, I'm confused because they sound like the same processes.
Speaking of orthodontics, my hygenist told me a small yellow-ish spot on one of my teeth is the dentin showing through where a bracket for braces was affixed and wore down the enamel.
So, is there hope for remineralization of that area or does that come under the heading of growing back enamel?
