Did you know that the history behind seeing the dentist twice a year comes from military history? That’s right – over 50 years ago, the teeth of the soldiers entering the armed forces were so bad, that dentists created the rule of thumb of twice a year dental care to improve dental health for all Americans. And to this day, this generality applies – to keep your smile up-to-par, you should visit your dentist in Nashville at least every six months. While some patients may need checkups and cleanings more often, the team at Green Hills explains why you should come in for an exam regularly.
