Hi Db7,
due to chemo and rads 3 years ago, i am now experiencing numerous dental issues. On 12/3 I am having my upper teeth replaced with some brand new ones. The bottoms will have to wait till early next year which will need to include 20 ore and 20 post hyperbaric chamber sessions. I have a broken tooth on the bottom that sometimes my tongue rubs on. after a day or two of irritation it would get swollen and become worse. I remembered back to my days of wearing braces and bought some orthodontics wax at the drugstore and molded it around the tooth till the swelling subsided. Works great. Maybe it's worth a try and see what happens.
