Had a molar extracted. 2+ months ago. Went back for checkup 1 week later. Teeth lined up. Healed normal. And then out of nowhere- 5 weeks later - my jaw retracted.severly. My chin and neck align.  Now have overbite significantly. And my bite is off alignment. And if I relax - my tongue hangs out through my teeth. Its scary because it happened so quickly. Ive been a TMJ clenched for years. But this is crazy weird.
Hi. Thanks for the query. The symptoms of sudden retraction of the jaw with increase overbite and also loss of alignment of teeth is pointing towards jaw dislocation. You should consult an Oral Surgeon and get evaluated so that a thorough clinical examination should be done followed by a panoramic x-ray to rule out the exact condition of the jaw joints. Once the exact status is ruled out and if the jaw is dislocated then it can be reduced into its appropriate position either by manual reduction or surgery. For now avoid straining the jaw too much to try to bring it to normal position and take a soft diet. The Doctor can also advise you mouth guards in case if you have teeth clenching habit. Physiotherapy and stress relaxation techniques shall also be advised. Hope this helps. Regards.
