Portland is one of the few major (sort of) cities in the US that does not flouridate its water. When I moved here and went to my first Portland dentist, she looked at my X rays and immediately said "I can tell you're not from here". She told me the difference between the teeth of people who grew up in Portland, without fluoridated water, and people who grew up elsewhere, with fluoridated water, is very obvious to her. No, the Portland natives don't have better teeth.
