Q. Hi. I am thirty years old. I have been grinding my teeth in my sleep for most of my adult life. I now wear a gum guard to prevent any further damage. The only trouble is my two front top teeth look more like fangs now and are really thin at the ends. these two teeth are also over crowded and turn into each other. I would love veneers but I am worried about damaging them because of my habbit. Please help. Thanks.,
