Can Weight Lifting Cause TMJ? Yes, and Here’s Why

What Is TMJ Disorder?

TMJ disorder, or temporomandibular joint dysfunction, refers to problems with the hinge connecting your jaw to your skull. This joint allows for movements such as speaking, chewing, and yawning. When this area becomes strained or damaged, it can lead to pain, limited mobility, and discomfort.

Does Weight Lifting Cause TMJ?

The answer lies in how you approach your workouts. While lifting weights is a great way to build strength, improper techniques or tension during exercise can strain your jaw muscles, leading to TMJ symptoms. Here’s how:

Clenching Your Jaw While Lifting

It’s common to grit your teeth when lifting heavy weights, especially during exercises like deadlifts or squats. However, this can strain the jaw muscles, contributing to TMJ pain.

Improper Form and Posture

Poor posture and improper form don’t just affect your back—they can also strain your jaw. Lifting without proper alignment can overwork muscles in your neck and jaw, impacting the temporomandibular joint.

The Impact of Lifting Above Your Shoulders

Exercises such as shoulder presses require engaging multiple muscle groups, including the neck. This can pull on neck and jaw muscles, worsening TMJ symptoms for those already affected.

Preventing TMJ Disorder From Weightlifting

Prevention is key when it comes to protecting your jaw during weightlifting. Here are some tips:

• Mind Your Jaw Position: Instead of clenching your teeth, keep your mouth slightly open or relaxed to reduce pressure on the jaw muscles.
• Focus on Proper Form: Good form minimizes strain on your jaw and neck. Work with a trainer if needed to ensure you’re lifting correctly.
• Wear a Mouthguard: Wearing a custom-fitted mouthguard can cushion your jaw and prevent clenching. Consult a dentist to ensure it won’t shift pressure onto your jaw.
• Warm Up and Stretch: Stretching neck and jaw muscles before and after training can reduce tension.
• Speak With Your Doctor: If you already have TMJ disorder, consult your doctor before starting a new workout routine to prevent aggravating your jaw.

Weight Lifting and TMJ Symptoms: What to Watch Out For

• Jaw pain or discomfort
• Clicking or popping sounds in the jaw
• Jaw stiffness or difficulty opening your mouth
• Neck or shoulder pain linked to jaw tension
• Headaches or facial pain after intense workouts

Long-Term Impact of Weightlifting on TMJ

If TMJ symptoms from weightlifting aren’t managed, they can worsen over time. Chronic clenching, poor posture, and strain from improper lifting may cause ongoing pain or limited jaw mobility. In some cases, individuals develop bruxism (teeth grinding), further aggravating the jaw.

Conclusion

Weightlifting itself may not directly cause TMJ, but poor habits—like jaw clenching or poor posture—can strain your temporomandibular joint. By staying aware of jaw tension and maintaining good form, you can enjoy weightlifting without risking TMJ issues.
