What are common symptoms of tmj? Can it cause ear/sinus stuffiness?

Symptoms of TMJ. Tmj symptoms vary for everyone but there are some common issues but a differential diagnosis is needed to eliminate other diagnoses. Tmj is very complex and proper diagnosis and treatment plan is very important. Some symptoms can be pain on chewing, opening, headaches, sore neck, breaking of teeth, ringing ears, and sore muscles. Go to a dentist for proper diagnosis.
Several Signs. Soreness and pain of the jaw muscles, pain around or in the ear, inability to open the jaws widely without pain are some symptoms of tmj. It may feel like ear stuffiness and is sometimes confused with sinus problems. An infected/abscessed tooth can give similar symptoms. See a dentist for evaluate, diagnosis and treatment options.
Many. Pain and tenderness of your jaw; aching pain in and around your ear; difficulty chewing or discomfort while chewing; aching facial pain; locking of the joint making it difficult to open and close your mouth; headaches; uncomfortable bite; and finally, uneven bite because one or more teeth make premature contact.
TMJ Dysfunction. Ear and sinus stuffiness is only one of many signs and symptoms of TMJ dysfunction. Among others are, headaches, facial pain, popping/clicking in the joint, joint pain, limited mouth opening, neck pain, shoulder pain, visual disturbances, dizziness and jaw locking open/closed. The symptoms can have a wide range. All symptoms must be considered and examined to make sure of the proper diagnosis.
Yes. Jaw pain, especially at area of the joint; popping/clicking of jaw; ear pain, or sounds of cracking in the ears: ringing/popping sounds in the ears (tinnitus) or a sense of fullness in the ears: headaches; blurred vision: tight, stiff, or sore jaw or neck muscles: facial pain, cheek pain, or chin numbness or tingling: shoulder pain; locking or dislocation of the jaw (usually after widely yawning).
Pain and dysfunction. If the tmj/tmd issues last for awhile, some symptoms can affect the ear (s) in many ways. You may develop ringing in the ears; earaches, popping-grating-clicking that is heard constantly in the ears; roaring muffled sounds; hearing loss; on and on. It is better to see an ENT first if you have ear symptoms to rule out it being the ears as the source of the problem.
