Conversation

I just found out I have an underbite after my dental check-up.

Really? I didn't know that was a thing!

Yeah, it means my lower teeth stick out more than my upper ones.

That sounds uncomfortable; are you going to get it fixed?

Root Explanation

Underbite → It is formed from "under" (from Old English "under", meaning beneath or below) and "bite" (from Old English "bītan", meaning to cut or grip with the teeth). The word "underbite" refers to a dental condition where the lower teeth protrude beyond the upper teeth, hence the lower (under) bite.

Memory Tip

Think of something that is 'beneath' ('under') the upper teeth when you bite — that's what an underbite means.
