I had intense jaw pain after some dental surgery last year. Still have it. Two things happened. the surgery activated a viral infection. HSV-1 which apparently lives dormant in the nervs in your jaw, the trigeminal nerve. Also having my mouth open that long and so awkward, I burst the disc that is in the jaw joint. I had an MRI and it was plain as day how damaged the joint was. So now I wear a special splint at night to keep from clenching and I use msucle relaxers to calm the jaw muscles and I use ice and heat to try to treat it

The ear pain sounds very similar to what I experienced.

Ask your doc to send you to a TMD (temporal joint derangement) specialist.

KNow that with the right treatment it does heal
