How Poor Posture Can Play a Role in TMJ Disorder
August 3, 2026

If you’re currently suffering from persistent discomfort in your jaw, your posture may be partially to blame. Jaw pain is often the result of a TMJ disorder, which is an issue with the temporomandibular joints (TMJs) that allow you to move your lower jaw. A TMJ disorder can have multiple contributing factors, and poor posture is often on that list. Here’s a closer look at how the way you hold yourself can affect your jaw.
The Link Between Poor Posture and TMJ Disorder
When you look at your phone or work on your computer, you may have a tendency to slouch or stick your head further forward than you normally would. This can change the position of your jaw, which can increase the amount of pressure on your TMJs. When the jaw joints are exposed to too much stress, it can lead to a TMJ disorder. Not only can this condition cause persistent jaw pain, but it can also result in other symptoms such as headaches, neck pain, earaches, and periodic locking of the jaw joints.
Changing Your Posture to Protect Your Jaw Joints
If your posture really is contributing to your TMJ disorder, you’ll want to take steps to correct it as soon as possible. Whenever you sit down, try to resist the urge to lean forward; you should keep your back pressed against your chair. If you often find yourself slouching in order to get a closer look at your computer, it may help to raise the screen to eye level.
It’s worth bearing in mind that sitting down for long periods of time can cause you to clench your jaw or tense your neck; both of these factors can make your TMJ disorder worse. As such, it’s a good idea to stand up every hour. Spending just a few minutes on your feet can have a positive impact on your jaw joints.
On that note, it’s important to be aware of your posture while you’re standing or walking. Try to carry yourself as though you have something balanced on your head; this can help you avoid slouching.
In summary, your posture can have a significant impact on your jaw joints. As such, making a few changes to the way you stand or sit can be an important step for getting your TMJ disorder under control. Of course, you should also make a point of reaching out to your dentist so that they can properly diagnose the problem and create a treatment plan to help you achieve lasting relief.
