John,
There are different types of jaw pain. The type that feels like a vice, squeezing your jaw, may be cardiac related. Others may have to do with an infection or osteonecrosis of the jawbone. Best to have it checked out.

I wear dentures.hematologist doesn't think there will be a problem. I hope he is right.

I get some TMJ a few times, never lasts too long, right side and I did go to dentist before diagnosis for my jaw TMJ, gave me a steroid and a month later when I finally got in with oncology I was diagnosed. I think it’s one of my symptoms or when my body has extra inflammation.

I’ve had recurring jaw pain on the right side, and I don’t know what is causing it either

Do you get Xgeva injections? Prolonged use of Xgeva can cause issues with the jaw/teeth. I would talk with your hematologist/oncologist and your dentist also. I was fortunate that my dentist was aware of MM and possible issues with the mouth.
