Thank you for the reply. Dental care is a big deal even before starting Radiation. At the University Dental clinic I went to, they fitted me with upper and lower teeth guards to use daily with Fluoride gel after radiation treatment. Because of the significant oral pain and sensitivity, I didn't try the Fluoride get and guard until months after radiation. Then the prescription was way too strong that caused burning. After several tries of different potency, I found that berry flavored Colgate Gel Kam o.4% worked the best. However, it is mildly irritating, so I apply it with a soft tooth brush before bed at night. I lost one lower molar over the course of a year, slowly loosening then just falling out. It was not recommended to pull the molar in the highest radiated section of the jaw due to concern for microvascular trauma, infection, and finally osteonecrosis. Unfortunately, the molar in front of that tooth also became loose, resulting in periodontal abscess. The molar was a root canal and never became as sensitive with chewing as did the first molar. The approach was to shave off the top part of the molar to expose the biforcation of the root, fill the roots in with amalgam, This allows better cleaning at the site of the biforcation. The roots will eventually fall out. I have used Chlorhexadine mouth rinse periodically for gum inflammation around the loose molars, but it burns due to the alcohol content. I simply syringe a small amount around the gum of the loose tooth. I don't tolerate most tooth pastes with mint flavor, so I use children's berry flavored toothpaste. I brush and floss twice a day and use the water pick after each time I eat 3 times per day. I don't tolerate most mouth rinses b/c of the peppermint and use Biotene rinse highly diluted. (a few squirts in a cup of water). It gives temporary dry mouth comfort. I found a non-flavored mouth rinse called KloSYS at Walmart that is not irritating but doesn't offer lubrication. This will likely be a lifetime regimen.
