Since I was a teenager and my whole adult life I've had excellent hygiene with my teeth and everything. I have ocd too.So anyways I don't floss every night but 4 times a week. I been using spin brushes since they came out.I use mouthwash daily. I brush my teeth twice a day and thoroughly.Despite being so clean my molars and wisdom teeth have all rotted FROM THE INSIDE?!?! Dentist all think I have bad teeth hygiene and have said as much. I have no top molars and 2 left on the bottom. My left side lower tooth hurts and needs pulled I can tell it's hollow out.Dors this happen to anyone else. My sister in law has lupus and has the same problem.
