How to Exercise Your Jaw (Without Making It Worse)
Healthy’s Summary
Yes, jaw exercises are a thing. Whether you’re trying to define your jawline, reduce tension from clenching, or help with TMJ symptoms, moving your jaw on purpose (and in the right way) can actually help.
But—and this is key—it’s not about chewing gum for hours or buying some sketchy resistance gadget you saw online. Real jaw exercises can improve strength, mobility, and even help release tension if done properly. That said, the jaw is a sensitive joint, and overdoing it (or doing it wrong) can make things worse.
How you should approach jaw exercises depends on your goals—cosmetic, functional, or therapeutic. Your habits, tension levels, and even how you sleep can all play a role.
So… Why Exercise Your Jaw in the First Place?
Most people don’t think about their jaw until something feels off. But your jaw does a lot of heavy lifting—chewing, speaking, facial expression, and more. When muscles in this area are either too tight or too weak, you may start to notice discomfort, clicking, clenching, or even pain radiating into the head and neck.
Reasons people start jaw exercises:
- To reduce tension from clenching or grinding (bruxism)
- To manage symptoms of TMJ disorders (jaw pain, stiffness, clicking)
- To strengthen after an injury or surgery
- To improve jawline definition (though results may vary)
- To ease discomfort related to poor posture or stress
Jaw exercises can help improve muscle balance and coordination—but the goal isn’t to bulk up your jaw like a bicep. It’s to gently strengthen and stabilize without causing strain.
A Few Safe Ways to Exercise Your Jaw
Here’s where we introduce gentle, controlled movement. No fancy tools or high-rep sets required—just a quiet moment and some body awareness.
1. Jaw Opening and Closing (With Control)
Sit upright. Gently lower your jaw as if yawning, then slowly close it. Keep it straight—no shifting side to side. Do this 5–10 times, slowly.
Why it helps: Trains smooth motion and stretches tight muscles.
2. Resisted Jaw Opening
Place your thumb under your chin. Try to open your jaw slowly while applying light pressure with your thumb. Hold for 3–5 seconds, then relax. Repeat a few times.
Why it helps: Builds strength in weak or underused jaw muscles.

3. Side-to-Side Motion
Gently slide your jaw to the right, then back to center, then to the left. Only go as far as is comfortable.
Why it helps: Improves range of motion and coordination.
4. Tongue-to-Roof Press
Rest the tip of your tongue on the roof of your mouth (just behind the front teeth). Slowly open and close your jaw while keeping your tongue in place.
Why it helps: Engages deeper stabilizing muscles and improves alignment.

What About for Jawline Definition?
This part gets a lot of buzz—especially on social media. But here’s the real talk: jaw exercises can help improve muscle tone, but they won’t burn fat specifically from your jaw or give you a chiseled look overnight.
If your goal is jawline definition:
- General body fat percentage plays a bigger role
- Posture affects how your jawline looks
- Facial muscle toning can offer subtle improvements
That said, regular gentle exercises may improve symmetry and reduce puffiness caused by tension. Just don’t expect dramatic sculpting from chewing on silicone devices or “mewing” 12 hours a day.
When to Be Cautious (or Stop)
Jaw pain isn’t something to push through. If you’re already dealing with TMJ issues or frequent headaches, talk to a provider or physical therapist before starting new exercises.
Stop if you feel:
- Pain during or after the exercises
- Increased clicking or locking of the jaw
- Dizziness, ear pain, or headaches
These could be signs of joint irritation or imbalance—and continuing might make things worse. Less is often more when it comes to jaw health.
The Takeaway
Exercising your jaw can be helpful—but it’s all about balance. Whether you’re trying to ease TMJ symptoms, reduce tension, or subtly tone the area, slow and gentle movements are your best bet. Don’t fall for gimmicks or overdo it. With the right approach, you can support a healthier, more relaxed jaw without causing new problems.
