Aside: I was surprised to read "dental caries" in the list of things detectable through similar methods in the court filing screenshot in this post. Is that about a device that could optically detect caries from tooth surfaces through similar principles?
If you've ever put a bright light up to your teeth in a mirror, it's pretty incredibly how translucent dental enamel actually is, and the level of internal detail you can see just by eye.
That’s how dentists check for issues as well: they very briefly shine a light through your teeth and capture a picture the resulting shadow.
"Light"?
Most light won't make electrons frolic in your body.
Also a nice way to realize how cracked your teeth might be.
Startup opportunity for a light based 3rd tooth scanner?
Check if glidewell has a patent on it first. They have the smallest intra-oral scanner I've seen, and I saw it 12 years ago. It's like a cigar. I may be wrong and they didn't make the scanner.
