My jaw clicks and pops alot too. I know have TMJ. I also catch myself grinding my teeth alot.
The last time I went to the chiropractor I asked him if he could help with this, because it was causing pain in my ears, also they were plugged too.
He gave my whole jaw area a really good rub down, and he checked the joint when I opened my mouth and the closed it. It really is off kilter. After the apt. my jaw was very tender, but it sure did help.
Do you have a good chiropractor or reg. doctor. Maybe if your not having any pain yet, then they could help realign it.
Good luck I now how awful the clicking is, I think mine started after extensive dental work 24 yrs ago. Diana
