It seems that my enamel was brushed off from several teeth because I was unwittingly using, not my usual extra soft brush, but a soft one. At any rate, one dentist said it's ok to leave these teeth as they are, with the dentine exposed. Another one said I need crowns for all of them - I wonder if veneers could be indicated instead, if at all necessary. Could bacteria be getting into the teeth slowly so that I will eventually have pain? Could these teeth already be infected even though they don't hurt yet? By the way, I only eat complex, not refined carbohydrates or any sugar whatsoever. Any information about this will be greatly appreciated.
