I am taking 200mg of DOXYCYCLINE HYCLATE for Roasia. To avoid antibiotics EVERYDAY, I will stop taking for a few weeks when my skin is clear. I notice after I have taken it for over a week, that my teeth hurt, specifically where I know I have issues and need dental work. When I stop taking it, the discomfort goes away after a day. Is that common? Could it effect my teeth long term?
