Just wondering how often posters on here get their teeth x- rayed. My dentist, who is fairly young, insists I get them every year. (Actually wants them every 6 months) I Googled , and it looks like I could get by with every 36 months based on my history- no cavities for 17 years now, no other problems or complaints. Full disclosure, my dental insurance pays for one set/ year, and I’m not overly concerned about the radiation. But if I don’t really need them, why risk the exposure?
