Are TMJ Disorders (TMD) Genetic?

You have two hinge-like joints on your face, one on each side of your jaw. These joints let you open and close your mouth! Many issues with these joints – which are called temporomandibular joints – are classified as temporomandibular disorders or TMD. Millions of people develop TMD, but is it genetic?

TMD May Have a Genetic Link

TMD is a puzzling condition. TMJ disorders (TMDs) do have a genetic component—but that’s not the whole story. While genetics can play a role, factors like jaw injuries, stress, and certain habits often contribute to TMD, too. Studies suggest there may be a genetic association, and many people who have close relatives with TMJ disorders end up developing TMD, too. You can’t control your genetic risk factor, but you can protect your joints by wearing a mouthguard while playing sports, wearing a nightguard if you grind your teeth, avoiding excessive gum chewing, and making sure you don’t clench your jaw during the day.

TMD: Common Symptoms

Not all jaw pain is TMJ-related, but it’s a good reason to schedule an appointment with a dentist. Along with jaw discomfort or stiffness, TMD can significantly impact your life by affecting your ability to chew, speak, or even yawn comfortably. Other common symptoms include:

• Pain or tenderness in the jaw joint and chewing muscles
• Clicking or popping sounds when opening or closing your mouth
• Facial, neck, or ear aches that can worsen over time
• Locking of the jaw, making it tough to open or close your mouth fully
• Lockjaw

TMJ Pain Can Be Managed

There are many treatments for TMJ pain. Some are expensive, such as surgery, but many people manage their pain with custom mouthguards, simple stretches, hot and cold compresses, and reduced stress. Custom-made mouthguards, which are available at Blue Valley Smiles, are another great tool. Made to perfectly fit your mouth, they relieve pressure on your jaw and prevent you from grinding your teeth. Sometimes if jaw pain is related to teeth misalignment, orthodontic treatment with Invisalign may provide relief.

TL;DR

Are TMJ disorders genetic, or can they develop over time?

TMJ disorders can have a genetic link, but other factors like stress, injuries, and teeth grinding also play a role. Even if you inherit a higher risk, you might never develop symptoms unless habits or lifestyle factors trigger them.

If my parent has it, will I definitely get it?

Not necessarily. A family history raises your risk, but it doesn’t mean you’ll have TMJ symptoms for sure. Staying mindful of habits like clenching your jaw or grinding your teeth may help you avoid issues.

What can I do if I have a genetic tendency for TMJ problems?

Consistent self-care can lower your chances of developing painful symptoms. Practice stress relief, avoid excessive chewing or gum, get regular dental checkups, and address any grinding or clenching to help protect your jaw joints.

Are there inherited conditions that raise the risk of TMJ disorders?

Yes. Conditions like rheumatoid arthritis or certain connective tissue disorders can run in families and increase the chance of TMJ issues. Even then, not everyone with these conditions will develop TMJ pain.
