Routine dental X-rays are not backed by evidence

Current final year dental student pitching in here. While dentists of the past may push for unnecessary annual radiographs, the curriculum in dental school has changed to favour evidence-based dentistry. Annual bitewings are only indicated if you're a high caries risk, and, as the article mentions, 2-3 years if you're low caries risk. So your younger/newer dentist will be following much better protocols (and hopefully not scamming you)!

Slightly worrying that evidence-based dentistry wasn't the default position (though not surprising). I'm always kind of amazed that when I look up the robust evidence for even things as common as flossing, the evidence just...doesn't seem to be there. Let alone all the myriad of dental products from various mouth washes, tooth pastes, brushes and water picks.

How we've ended up regulating medicine to the nth degree, but when it's teeth we're like "oh well, lol", continues to mystify me.

Not directly related to the topic at hand, but it amazes me how Dutch healthcare insurance does not cover dental care by default, and you have to get an extra package for that. As if dental health is not part of my regular health? Why are teeth treated differently from the rest of the body?

Here’s a good answer that tracks with what my parents, who are dentists, told me: https://www.reddit.com/r/explainlikeimfive/s/H4MsnWKatM

> For the longest time, surgeons, dentists and optometrists weren't part of the medical profession. You'd have a barber who could give you a shave or pull your teeth, or a butcher who could cut up a hog, or cut off your gangrenous leg. Optometrists were craftsmen who made the spectacles in their shop. Doctors were University educated in Latin and Greek to read ancient medical texts and despised the uncouth yokels.

> Surgeons muscled their way into the medical profession, originally with the help of the Royal Navy, who only had space for one or two people in charge of both cutting off legs and looking after crew health on their ships.

> Dentists and optometrists never did, so they started their own universities, certification boards, etc. By the time they became respectable enough for people to try to merge them with the medical establishment, in the 1920s, they had no desire to give up their independence.

> The first insurance policies were private contracts with groups of doctors and the system developed from there.

Details vary from country to country of course, but the gist of it generally holds true.

Note that "optometrist" is distinct from "ophthalmologist", which is the actual eye doctor. The optometrist job is only about fitting glasses and contacts for near/farsightedness, while ophthalmologists can treat all manners of eye diseases.

And the final form of dentists, oral-maxillofacial surgeons are an all in one and have to study general medicine, surgery and dentistry.
