The way your teeth meet when your upper & lower jaw close down is bite. If your teeth don’t fit properly, you could have malocclusion or bad bite which can cause- TMJ Problem (Teeth, gum, muscle of face).
If TMJ problem is left untreated, then it causes some people to clench the jaw & grind their teeth at night. This can cause migraine as well as neck & shoulder pain, even back pain.
If you recognize any of these symptoms or suffer with these on a daily basis, you will need to see a dentist to get it treated or refer you to a specialist.
