Eli5: Why do animals don’t have to brush their teeth ?
In: 1
1. Lack of sugar and acids in the diet compared to what most people eat
2. They DO get some “brushing” action from eating plant material. Almost everything eats at least some plants.
3. You’re probably underestimating how many animals do end up with dental problems, and then they just starve and die. All the animals you see with good teeth is survivorship bias. The ones with tooth rot died so you’re not seeing them to notice it.
