Even if your teeth look clean, is it necessary to have your bite checked at the dentist?

I think I've developed a habit of chewing on only one side lately, but since my teeth don't actually hurt, I'm just watching it.

I heard at the dentist that even without pain, long-standing habits can cause excessive force to be applied to certain teeth, so it's bothering me for no reason.

I'm not sure if it's right to mention even this much during the checkup.
