Denterexic
When someone has white teeth but they think that their teeth are yellow so they obsess over brushing their teeth/whitening them. Similar to anorexia but involving an obsession over teeth rather than weight.

Jim: "Oh, we'll I'm just gonna brush my teeth again later anyway."
Bob: "Wow you actually have a problem. You might even be denterexic."
