Many fitness trends promise to tone or reshape parts of your body, and in some cases, this works. Muscles in the arms, chest, stomach, or glutes can be sculpted with targeted exercises because these areas have large muscles capable of building definition. However, other areas, like the jawline, don’t respond the same way. Despite claims from products like the JawlineMe Fitness Ball, there’s little evidence that exercising your jaw can improve its definition—and excessive use of these devices may even damage your jaw joints.
What Really Shapes Your Jawline
Most of your jawline’s structure comes from bone, specifically the mandible, which connects to your skull in front of the ears. While several muscles attach to and move the jaw, most are located in the cheeks and neck—not along the edge of the jaw itself.
Smaller muscles along the jaw mostly help move the lips and skin. Exercising your jaw with a resistance device primarily works the larger cheek muscles, not the ones that define your jawline. To target the minor muscles, you’d need to make exaggerated facial expressions, not push or pull your jaw against resistance.
Why Jawlines Become Less Defined
Jawline definition depends on three key factors: development, weight, and teeth.
- Jaw development: Many people never fully develop their jaw structure, often due to a lack of chewing hard foods during childhood. Modern processed diets require less jaw activity, which can result in smaller jawbones. This is one reason why many people need wisdom teeth removed—they simply don’t have enough space.
- Body weight and fat distribution: Extra weight stored in the cheeks and neck can obscure your jawline. While overall weight loss can reduce facial fat, targeted jaw exercises won’t selectively burn fat in this area.
- Tooth wear and facial proportions: Your teeth help support the overlying soft tissue. Over time, worn teeth can cause the jaw to shift slightly upward and backward, making the jawline appear less defined. Cheek fat pads and gravity can further reduce jaw definition.
The Risks of Jaw Exercisers
Using jaw exercise devices may seem harmless, but they can strain your temporomandibular joints (TMJ). These complex joints are designed to provide mobility and strength, but they are vulnerable to repetitive high-stress activity. Overuse of a jaw exerciser or frequent chewing of non-food objects can contribute to TMJ disorders, causing pain, clicking, and jaw dysfunction.
A Safe, Effective Alternative: Nonsurgical Facial Rejuvenation
While exercises won’t reshape your jawline, a neuromuscular dental approach can help. By assessing the relationship between your jaw, teeth, and facial soft tissues, we can restore proper jaw alignment and improve your facial contours.
When this evaluation is done with a focus on aesthetic rejuvenation, it’s often referred to as a nonsurgical facelift.
This treatment can:
- Restore youthful jaw position
- Rebuild worn-down teeth to support facial structure
- Improve jawline definition
- Enhance your smile and overall facial appearance
