UNDERBITE
An underbite is when you close your mouth and your lower front teeth are in front of your upper teeth. In many cases, this is actually a problem with your lower jaw being too far forward.
An underbite can make it hard to chew properly and speak clearly, and it might cause your teeth to wear down more quickly.
