Yes it could. You might be clenching your teeth too without realizing it, or even doing it in your sleep. A lot of people have a class B bite on their teeth, meaning that it is slightly crooked, so you will be able to be more tense on one side than on the other. It could You might want to look at being adjusted by a chiropractor. Warm compresses to loosen the muscles will help.

Since you have no pain, it doesn't indicate that it is TMD necessarily, but we do have a forum on that too if you want to post there.

thank you so much for your response! I was thinking that it could be a wisdom tooth growing in or something but I have no pain and my jaw isn't swollen so I have everyone confused, including myself.

I am going to head to the doctor's office later today though cuz it seems to be worse today.

I'm thinking I might have a class B bite cuz sometimes I have to adjust my jaw after yawning really wide or something. And it's the right side that i have to adjust, which is the problem side at the moment.

Should I see a dentist?

Some dental work might fix it, braces, a splint, or chiropractic... most people have this problem, it's just more or less bothersome. I have it too, but it gets worse when I'm in stressful situations and set or clench my jaw, it clicks when I eat really chewy food, like a crusty bread or tootsie roll. It doesn't bother me too much unless someone hits it or I aggravate it of course.

You might be on the path to having a bad problem or it could just stay the way it is forever, or it might go away. I found chiropractic to be the best solution for me because I have get adjustments for my back as it is and we'd just handle that while I was there. He used a mechanical activator method, which is really gentle and effective.

My symptoms come and go. Sometimes one of my kids who I'll have on my lap struggles and hits it and throws it off so that it's painful. Sometimes I forget I have it but then there was once I aggravated it so badly that I couldn't open or shut my mouth for a few days and had to get the chiropractor to fix it in a few sessions (never try to bit the ear off a frozen chocolate bunny lol.)

I think you would really benefit from posting in the TMJ (TMD forum). There are a lot of knowledgeable people there with the same issues and can probably give you more tips than I can.

The strangest thing just happened..

My lockjaw is gone! However, the right side "pops" and i have to set it back to align it. I'm still going to the doctors though.

I've had the alignment issue for years but never bothered me. The right side would just "pop" out of place and I'd "pop" it back in. I never experience any pain.

I noticed that if I pop it back into place and try to open and close my mouth i feel the tense "lock jaw" feeling again or it'll just pop back out. But if I do an "under bite" with my jaw it'll "pop" and the tense lock jaw feeling goes away.

I will check out the TMJ/TMD forum.. thank you SO MUCH for your help, I really appreciate it

No problem... the incidence of increased stressed probably just took the problem to a peak to make it more noticeable. I'm glad I could help you out
