Not able to eat due to the inability to open my mouth all the way. how to fix the tmj problem?

Several ways.: Limited mouth opening may be caused by a displaced TMJ disc. The best way to determine this would be with a TMJ mri. If the disc is completely displaced, which is common with limited opening, then TMJ arthroscopy has the highest success rate. This is where a tiny scope is inserted into the joint under anesthesia and scar tissue can be released and full range of motion restored with relief of pain.

Many ways: There are many causes and many solutions to TMJ disorders. I would get in to a dentist that deals with tmd soon if i were in your position.

Ibuprofen to start: You have some sort of a closed lock of your tmj. This is a significant sign of a major jaw dysfunction. Only eat a soft diet, take anti-inflammatory medications, try a cold pack to the affected jaw area. You need to make an appointment with a TMJ type dentist right away on monday as this can get worse or pain can intensify a lot.

See your dentist: Your dentist will determine the cause of limited opening. It can be due to muscle spasms of jaws or TMJ issues. X-rays will be taken. Depending on the problem, your limited opening can be treated.

See TMJ Dentist: When you can't open well, this can have a serious effect on your overall nutrition. You need to see a TMJ dentist right away. In some circumstances, you may also need the assistance of an oral surgeon. You may need "manipulation under anesthesia" to help get the disc back in the right place. In conjunction with that, you need follow up with the TMJ dentist to put your bite back in the right place.

Closed lock: You apparently have closed lock of the jaw joint/joints- limited opening. I would see a tmj/tmd specialist asap.
