Having had two teeth extracted a week ago, I can tell you a bit about teethaches.<(JK) These tooths, JK, were soo painful, and sooo far gone, from fine, ( less than a year prior), that they had to get gone. With all the meds, we take for sx from HCV, and for sx of tx, it's a wonder that any of us dry mouthed heppers have any teeth left at all. 'Oasis' Moisturizing spray for your mouth does help alot, to prevent such rapid decline of otherwise healthy teeth.
