Understanding Masseter Hypertrophy, Jaw Clenching & Facial Slimming
Maybe you wake up with a tired, achy jaw, your dentist has mentioned wear on your teeth, or you've noticed your face looks wider and more square at the angle of the jaw than it used to. These often go together, and they all trace back to one hardworking muscle.
The masseter is the chewing muscle at the corner of your jaw. Regular clenching or grinding, often during sleep or stress, can make it bigger, widening the lower face. The same habit can also cause jaw pain, tooth wear and headaches. Relaxing the muscle can slim the jawline and ease that tension, and we'll also look at the bigger picture, including your teeth, jaw joint and sleep, so you get relief that lasts. If your jaw shape comes mostly from bone, we'll talk about what will help most.
Causes and Contributing Factors
The masseter can enlarge in response to repeated, forceful use, most commonly habitual clenching or grinding of the teeth (bruxism), which may occur during the day or in sleep. Chewing habits, stress, sleep patterns, and, in some people, an inherited tendency toward a stronger or more prominent jaw muscle may all contribute. A naturally wider or more square lower face can also come from the shape of the jawbone itself. Bruxism is associated with factors such as stress and certain sleep and medication patterns, but the relationship is complex and not fully accounted for by any single cause.
Signs and Symptoms
Assessment
At Anti-Aging Medical & Laser Clinic, injectable treatments are performed by our experienced physicians. Our cosmetic consultants may help with your initial assessment and planning, while the treating physician reviews your suitability, confirms the medical plan and performs your treatment. We'll ask about clenching or grinding, jaw pain, headaches, sleep, stress and any dental concerns, and feel the muscle while you clench to check its size and firmness. We also look at whether the width of your lower face comes mainly from muscle, bone or the tissue over it, and if there's dental wear or joint trouble, we may suggest working with your dentist too. Your plan centres on what matters most to you, comfort or contour, along with your timing and budget.
Cosmetic consultations are complimentary.
Treatment Options
These are some of the options connected to this concern. The appropriate plan depends on assessment, suitability, and your goals.
Your plan depends on whether you're after symptom relief, a slimmer jawline, or both. For clenching and grinding, looking after stress and sleep helps, and your dentist may suggest a custom night guard. Our experienced physicians use Wrinkle Softening & Neuromodulators, placing a neuromodulator (botulinum toxin type A) into the masseter to calm its activity. Over time, this can reduce muscle bulk, soften the width of the lower face and ease clenching. Emface, which includes a dedicated protocol for jaw (TMJ) discomfort, is a needle-free option performed by our senior laser technicians under the medical direction of Dr. Gidon Frame.
Muscle-relaxing treatment is well suited to jaw width that comes mainly from the masseter. How long each option lasts is explained on its treatment and technology pages.

Medical Assessment
Medical or dental assessment is important if you have persistent or worsening jaw pain, difficulty or pain opening or closing the mouth, locking or clicking of the jaw joint, significant tooth wear or breakage, facial swelling, or a lump that is enlarging, one-sided, hard or otherwise changing. New, severe or unexplained facial or jaw symptoms should be checked promptly by a doctor or dentist.
Frequently Asked Questions
When the masseter is the main reason for a wider lower face, neuromodulator injections that calm the muscle can gradually reduce its bulk and soften the jawline, and they may also ease clenching. Individual results vary. We'll check whether your jaw width is mainly muscle and talk you through what to expect.
A wider or more square lower face can come from the chewing muscle, the shape of the jawbone or the tissue over it, and it's often simply a natural variation in facial shape. Knowing which one applies to you guides the right approach. We'll work that out together at your consultation.
It may help when headaches are clearly linked to clenching and muscle tension. Headaches have many possible causes, so persistent or severe headaches deserve their own assessment. We can help work out the likely source and plan from there.
