How often do you need to see a dentist?
A lot of us think that we should visit the dentist every six months – even if it’s not what we do in practice. Whether those biannual check-ups are really necessary is, however, a matter of debate. In fact, it’s not even clear where the six-month figure initially came from. Some believe it dates back to the 18th Century, long before the advent of randomised controlled trials that could test its benefits.
