Articular disc: The cracking or clicking noise that you hear when opening and/or closing your mouth is the mandibular condyle riding over the articular disc or meniscus which is out of its proper position in the glenoid fossa.
Dr. Daniel Sampson
Oral and Maxillofacial Surgery 26 years experience
Disc in the joint: There is a small disc of cartilage in the temporandibular joint that can crack or pop if it gets out of place. It rarely causes problems, but if you also have pain or limited motion, you should see your dentist.

Diskor arthritis: Starts with jaw disk out of position. Sometimes due to disk perforation with degenerative arthritis of jaw joint. Best option to sort out problem is oral surgeon.

Are jaw manipulations effective at treating tmj?

Maybe: Only way to know is to try it. But don't give up after only one treatment. And i would also get more than one opinion before jumping into jaw manipulation. I am not a fan of scraping bone against bone before other options are tried.
A 50-year-old member asked:

I chew gum a lot at work. Is it true that your jaw gets bigger when you chew gum?

No: The jaw is a bone, and like other bones it stops growing once a person reaches adulthood. The jaw should not get bigger regardless of what one chews.

Why does my jaw keep cracking?

Dr. Patrick Melder
ENT and Head and Neck Surgery 27 years experience
TMJ: This could be an issue with the temporomandibular joint (tmj). If you just hear a sound while chewing... That is the movement of the condyle of the jaw bone in the joint space. A popping sensation could be a problem with the joint cavity. A pain when chewing or talking could be inflammation of the joint space.
Dr. Kenneth Zipkin
Dentistry 48 years experience
popping or cracking usually is the result of a mismatch of movement of the lower jaw and it's protective capsule( stops bone on bone touching). This can happen because the muscles that move both are not coordinating well. See a DDS who treats TMJ

Cracking noises correlate with degenerative change in the joint due to arthritic change which happens when the TM joint is in a loaded posture.

A 41-year-old member asked:

I have swollen lymph node under my left jaw area. This has been off and on for about 8 months. Any recommendations?

Maybe not a node: It may be a swollen salivary gland and not a lymph node. In any event, you need to have a doctor examine it.
A 35-year-old member asked:

I have a lump near the lower part of my jaw, what is it possible that it is?

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph for anything bad like bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.
