I said I would let you know how my dentist visit went...so here it is. I had my teeth "cleaned" and checked. There was nothing, NOTHING on my teeth to clean! My hygienist asked me if I was having any problems, and I told her an honest no, and she asked if I had been using my appliance. I told her no.... I didn't need to. (I got it for sensitivity) She said so you don't like it ? I said no, I just haven't had a problem with my teeth being sensitive since I discovered oil pulling. What is that she said? Never heard of it. So, of course, I told her, and she was very interested in looking it up. She said my mouth looked great, and she went straight to the computer behind the receptionists desk as I walked out the door... presumably to look it up!!
