I'm looking for an expression to mean "crooked teeth", like those that need a dental bridge. A person who has all teeth, no cavity, but the teeth are just misaligned.
Could anybody please tell me other expressions than "crooked" and "misaligned"?

A friend of mine suggested "summer teeth", but this site says it means "missing teeth either by extraction or rotten from poor hygiene". So I guess it's not correct when the person has all teeth.

Any help appreciated? (I won't use it as a derogatory remark. I just want to describe that there are many such people in Japan, where the situation is different from the US and having croocked teeth doesn't mean they are poor or anything here. And I don't want to repeat "crooked" "misaligned" many times in my explanation, so I need to increase my vocabulary.)
