Q. Hi I am quite upset about recent findings from 2 different dentists that I have severe acid erosion and bruxism. 2 years ago I had no problems at all, although my diet/drinking habits have not changed. There are no problems with my gums or x-rays and I have never had a filling so now I am gutted about this. What I’d like to know is that I have been told different things by different dentists about the effects of swimming on teeth. I swim 3 times a week for 1 1/2 hours a time. This has been a new thing over the last 2 years. Could this be the problem and how can I check the PH levels of my local pool? My current dentist is insisting that I grind my teeth but I do not believe this to be true but at one time I was on a high dose of Citalopram and have read that this can cause grinding and I think it did in my case. I was on this for about 3-4 years. I am also a vegetarian and have been told this is the problem!!!??? so confused. What can I do and can I prevent further damage. I cannot stop swimming as this is now for me a form of anti-depressant. I am miserable. Thanks for you help.
