Why does my jaw feel so sharp and pointy concentrated mostly on two points mid body of the jaw after a punch to the jaw like 5 months ago? will it be permanent? can anything be done? i am getting a dentist night guard soon. i feel a lot of discomfort?

Jaw fracture: You may have a broken jaw. X-ray may show it. After 5 months it may already be healed.

Broken jaw?: Ask your Dentist for the name of a good Oral Surgeon in your area. Review of x-rays or preferably a CBCT would reveal the presence of a (by now) healed fracture.

See prior answers.: Did you have any medical evaluation at the time? The area should be evaluated by dental personnel...I would suggest an oral/maxillofacial surgeon. There is probably some interruption of the integrity of the jaw bone (mandible) due to trauma. More diagnostic study is required.
