I visit the dentist every five months for teeth cleaning and that's all that's necessary to be done. I have all my teeth except the widoom teeth were pulled 25 years ago, because the dentist felt, they were useless and could cause problems later. Every time I go, they are pestering me about X-rays. I think it is a money maker for them and I really can't afford them. Nothing was ever found during these sessions. My question is: do I still need them at my age (72) or should I just say: " I am done with that?"
