Our diet is nothing like what our teeth evolved for. For example for most people, cutting down the amount of sugars (down to levels similar to our prehistoric ancestors) they consume can go a long way in protecting dental health (and general health for that matter)

Teeth are amazing. One of the areas where human crystal formation happens. Our modern diets are horrible for teeth.

Evolution expects us to grind away about a millimeter of our teeth while we are young by eating rougher things to make way for wisdom teeth, for example.

For healthy teeth, you should be very hydrated. If your mouth isn’t watering, you might not be hydrated enough.

Well, teeth perform perhaps the most difficult task of the entire body. Take entirely external substances of all kinds of textures and densities and contaminants, crush all that to tiny particles, try not to get worn down too far in the process...

People in the past had better teeth than us, it's the sugar these days that cause so many dental problems. If you ate like those in the past, you similarly will have good teeth.

Spines seem to be similar in that regard. Huge "fuckup" (bound to fail badly) in many ways, but freed hands.

Feels like engineering: It's all trade-offs.

Sharks really got the good teeth genes.
