Is teeth clenching bad?

Yes: If not treated clinching will ultimately manifest itself in damaging either the teeth or the muscles of the jaw. See your dentist and get a night guard along with some exercises to take some of the stress out of those mucsles which should help decrease the clinching.

Yes: Even when we clench we are grinding a bit, not a lot of motion but our teeth have mountains and valleys normally, not flats, so biting still grinds the teeth a bit. Clinching can cause your to damage fillings as well. Likely you are grinding at night on top of that and may need an occlusal guard. Talk to you dentist about your options.

Yes: Clenching and/or grinding of the teeth can cause excessive wear of the teeth, pain in the muscles that function to open and close the lower jaw, and micro trauma to the temporomandibular joints with the increased loading.

Yes: Usually. Many people clench without problems. But your teeth can become sensitive, fracture, break or undergo excessive wear. You can develop jaw muscle pain, head and neck pain, and injury to your jaw joint (TMJ). Ask your dentist for guidance.
