Someone who is challenged dentally. This would be someone with severely crooked teeth. This could also be someone missing teeth. Rotting teeth also counts. These people usually haven't ever gotten their teeth cleaned.

Dentally retarded

Someone who *knows* they need to go to the dentist but keeps putting it off because they are scared, they don't want to spend the money, or they think the problem will just go away on its own.

Bob: My teeth are killing me.

Steph: Why don't you go see the dentist? You're always complaining about your teeth.

Bob: I don't wanna go.

Steph: Man, you are dentally retarded.
