Q. I have just had my braces taken off and now only have a retainer to wear at night. I hadn’t noticed before but the enamel on my front two teeth and a few of the bottom front teeth seems to have been worn away at the tips. Is there any way to build it back? Also, some of my teeth have wavy lines at the bottom instead of a straight edge. Why could this be? Is there any way of fixing this? In addition to this, one of my canine teeth is particularly large and more jagged than the rest of my teeth. Can this be re-shaped or filed down? Thanks.
