Well, yesterday I had a dentist appointment and things are not looking good with my mouth...  I have been very good about brushing and flossing since a few years ago when I had to have some extensive dental work done and I have been going to the dentist regularly - at least twice a year.  Well, yesterday the dentist found 5 cavities on my teeth and he said that I had more plaque build-up than he has ever seen on my teeth...  He kept making comments on how damaging to the mouth a lot of these cancer drugs are.  This is making me question even more if I want to stay on the Avastin or not...  I have to go back in to get the cavities drilled out and filled and the dentist is putting me on a prescription fluoride toothpaste.  He said that if that doesn't work at keeping the cavities at bay then we may have to switch to me sleeping with fluoride trays on my teeth at night.  He said that he has several other patients who have had dental problems while undergoing cancer treatments and a couple of them he has had to switch to the fluoride trays.  Definitely more to think about now...
