Q. Hi im 19 and just recently i noticed that my front four teeth are transparent and i was wondering what exactly is this? I’ve been reading for quite awhile now about this issue and it seems to be common, but no one gives a straight answer on what it is. I’ve read that it is loss of enamel and need to be looked at cause they are sensitive, or it is not enough calcium. Well my teeth are not sensitive to hot or cold and rarely bother me (other than appearance) and ive been taking calcium pills for some months now and still have seen no signs of change (other than white spots that appear on my teeth but then after a few times of brushing they fade away). I have looked into treatments and toothpaste and have been using toothpaste with liquid calcium (Arm & Hammer Age Defying / Pro Enamel) in it that claims to rebuild enamel, but this is my 3rd tube and again i’ve yet to see change. I did contact my dentist and asked about my problem and when i mentioned it they were hung over on lost enamel, but the more i told them i felt no pain or sensitivity, that i don’t drink soft drinks (have drank only water for about 2 years now), and rarely eat fruit plain or by it’s self, they became confused. Then i asked about the treatments i’d found (ex. synthetic enamel, and liquid calcium) and again there was a silence on the phone and they told me they had never heard of those and said that i should get veneers right away. (i feel they just wanted my money) I was wondering if these treatments work, or if there is another way to fix this problem other than cosmetics? For could it be a mineral / vitamin i am lacking in my diet?
