I agree with Wesley. I've never had a problem and I get mine down every six months. Infection in one's gums is not to be messed with as it gets into the blood stream very easily and can get into one's heart if their heart health is in any way dicey. In that case one takes pre-meds of antibiotics before a visit to the hygienist and dentist. Whatever you do, I wouldn't go back to the same dentist or hygienist!
