Can Poor Posture or Screen Time Lead to TMD?
DeForest, WI

Screens are everywhere now—work, social media, endless Zoom calls. Most of us spend hours hunched over, barely noticing how much time we’re glued to a device. But here’s something you might not have thought about: all that screen time, plus lousy posture, can damage your jaw. If you’ve noticed jaw pain, clicking noises, or even headaches, that could all tie back to something called TMD—temporomandibular joint disorder.

How Poor Posture Can Lead to TMD? 

Turns out, bad posture isn’t just a pain in your back. When you slouch, your head juts forward, shifting your neck and jaw out of alignment. That puts extra pressure on the muscles around your jaw joint, and over time, it can cause pain, stiffness, and other symptoms of TMD. Your body tries to compensate, which just builds up more tension through headaches, jaw aches, maybe even ear pain. Studies show that people who slouch a lot are more likely to run into TMD problems.

The Impact of Screen Time on Your Jaw Health

“Tech neck” is real, and it’s more than just a stiff neck. Staring down at a phone or laptop all day can disbalance your jaw, too. The longer you do it, the more those jaw muscles tighten up. Sometimes you’re so focused on the screen, you don’t even notice you’re clenching or grinding your teeth. That only makes things worse for your jaw joint and increases TMD symptoms.

What can you do if you’re dealing with TMD from bad posture or endless screen time? 

You’ve got TMD treatment options:

• Fix your posture. Sit up straight, keep your shoulders back, and line your ears up over your shoulders. It sounds simple, but it really helps.
• Take breaks from your screen. Try the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. It gives your eyes a break and lets your neck and jaw muscles relax.
• Do jaw exercises. Regular stretches and movements can loosen up tense muscles and help your jaw work the way it should.
• See your dentist. If your jaw’s already giving you trouble, your dentist can create a plan just for you—maybe a mouthguard, maybe physical therapy, whatever you need to get back to normal.

If you want to avoid TMD altogether, building a few good habits goes a long way:

• Set up your workspace so your screen is at eye level. That keeps your neck and jaw in a better position.
• Move around. Stretch, walk, or do exercises to improve your posture and relieve tension.
• Be aware of your posture all day, not just when you’re at your desk. Whether you’re sitting, standing, or lying down, try to keep your spine and neck lined up.

If you’re feeling jaw pain or discomfort after hours of screen time or bad posture, don’t just hope it goes away. TMD can be a hassle, but you can manage it with a few changes.
