Smarter people have better teeth
According to this recent study in the journal Intelligence, people with lower cognitive ability tend to have teeth that are missing or are in bad shape because they don't do the things that are necessary to have healthy teeth. This tendency was observed even after being adjusted for age, income, ethnicity, visits to the dentist, and smoking. The finding is consistent with the body of research showing that smarter people are healthier.
