How Phone Use, Posture, and Screen Time Can Affect Jaw Pain and Teeth

Are you a young professional or student at UNC in Greeley who spends hours hunched over your laptop or scrolling through your phone? Maybe you’ve noticed an increase in jaw pain, headaches, or even tooth sensitivity, but you don't realize that the two are linked.

This connection between screen time and dental problems is more significant than most realize and is becoming more prevalent with today’s tech-heavy lifestyles.

The Posture-Jaw Connection

Craning your neck forward to look at a screen creates a position often called "tech neck,” according to an article published by The National Institutes of Health. This forward head posture changes jaw alignment and places extra stress on the temporomandibular joint (TMJ) that connects your jaw to your skull. Over time, this misalignment can cause jaw pain, clicking, difficulty opening your mouth fully, and even chronic headaches.

Poor posture also encourages jaw clenching. When you hold your head in this forward position, your body compensates, tensing muscles throughout your neck and jaw, leading to unconscious clenching or grinding. You might not even realize you're doing it until you experience persistent pain.

Screen Time and Teeth Grinding

Extended screen time, especially before bed, can contribute to teeth grinding and clenching, called bruxism. The intense stress and concentration involved when you’re working, gaming, or scrolling endlessly can trigger the habit, which often continues during sleep. Over time, bruxism wears down tooth enamel, causes chips or cracks, and worsens jaw pain.

What You Can Do

Position your screens at eye level, take frequent breaks to stretch, and practice good posture throughout the day. If you experience jaw pain or notice signs of teeth grinding, like flattened teeth or morning headaches, schedule a visit with a dentist in Greeley, CO.

At Norco Family Dentistry, Dr. BJ Stewart and Dr. Shawn Buffington can evaluate your symptoms and recommend solutions like custom nightguards to protect your teeth from grinding damage. Addressing these issues early can help prevent worsening dental problems and help you maintain a comfortable, healthy smile.
