Definitely get that checked out, to eliminate medical causes. Dental things cause a lot of misery. I have decent dental insurance, but it still doesn't pay for things like implants or very much for crowns, etc. Thankfully, I haven't had much dental work in my life. But, my jaw/bite/TMJ has not been the same since I had a bike crash in Spain last year. I didn't get injured, but what started as a massive headache, settled in my teeth, and then became a weird clicking. My dentist told me a crash couldn't cause this, but I don't believe him. No pain now, just a weird bite and clicking.
Are you getting ready for another hurricane?
