Facial slimming & teeth grinding
CONCERNS
An enlarged jaw muscle can create a squarer, wider jawline and for many people, it comes hand in hand with teeth grinding, jaw clenching and tension. If you're noticing jaw tightness, wear on your teeth, or a heavier-looking lower face, it's worth understanding what's going on and what options may help.

What causes an enlarged jaw and teeth grinding?
Jaw enlargement and grinding usually develop from a combination of factors:
Overactive masseter:
The chewing muscle enlarges with repeated use.
Bruxism:
Grinding or clenching, often during sleep.
Stress and anxiety:
A major trigger for clenching, day and night.
Genetics:
Facial structure and muscle size are largely inherited.
Chewing habits:
Frequent gum chewing or hard foods build the muscle.
Jaw and bite issues:
Misalignment can drive clenching and tension.
Understanding the masseter and bruxism
The masseter is the main chewing muscle, running from the cheekbone to the angle of the jaw. Like any muscle, it grows with use - so people who grind or clench, chew gum constantly, or simply have a naturally strong bite can develop a visibly larger masseter over time. This shows as a squarer, wider or heavier-looking lower face, and is often more pronounced on one side.
Bruxism - grinding or clenching the teeth is extremely common and often happens during sleep, so many people don't know they do it until a dentist notices tooth wear or a partner hears it at night. Stress is the most common trigger. Over time it can cause jaw pain, morning headaches, worn or cracked teeth, and tension through the face and neck.
Because grinding is a dental and medical issue as well as a cosmetic one, we'll often recommend you also see your dentist, who can assess your teeth and bite and may suggest a night splint. Our approach can work alongside dental care where appropriate.
Areas we can help with
square or wide jawline
A heavier, squarer or wider lower face.
A square jawline is usually caused by an enlarged masseter muscle rather than the bone itself. Because the masseter sits right at the angle of the jaw, when it grows it widens the lower face, sometimes more on one side than the other. It's most noticeable when clenching, and often develops gradually in people who grind or clench.
jaw clenching & tension
Tightness, soreness or fatigue through the jaw.
Daytime clenching is often unconscious - many people notice their jaw is tight during concentration, stress or exercise. Over time it can leave the jaw sore or fatigued, contribute to tension headaches, and enlarge the masseter. Becoming aware of the habit is often the first step.
teeth grinding (bruxism)
Grinding or clenching, often during sleep.
Bruxism is involuntary grinding or clenching, most often during sleep, and is strongly linked to stress. Common signs include worn or sensitive teeth, jaw soreness on waking, morning headaches, and a partner hearing the grinding at night. It's very common and often goes unnoticed until a dentist picks it up.
facial slimming & contour
Concerns about the shape or balance of the lower face.
For some people the concern is less about grinding and more about facial proportion - a lower face that looks heavier or wider than they'd like. Whether this is muscle, bone structure or a combination is assessed at consultation, as the approach differs depending on the cause.
What to expect at your consultation
A jaw consultation begins with understanding what's driving your concern, whether it's muscle size, grinding, clenching, or a combination. Your nurse will take a full medical history, including any jaw pain, headaches, dental history and stress factors, and assess the masseter muscle at rest and when clenching.
We'll talk through what's contributing, whether a dental review would be worthwhile alongside anything we offer, and what's realistically achievable for you. From there, we'll create a personalised plan tailored to you.

+
Often, yes. Because both concerns commonly relate to the same muscle, they're usually assessed together at your consultation, and one plan may address both.
How do I know if I grind my teeth?

Many people don't, because it happens during sleep. Common signs include a sore or tight jaw on waking, morning headaches, worn or sensitive teeth, or a partner hearing it at night. A dentist can often confirm it from tooth wear.
Should I see a dentist about teeth grinding?
+
Yes, bruxism is a dental issue as well as a cosmetic one. A dentist can assess your teeth and bite and may recommend a night splint. Our approach can work alongside dental care where appropriate.

+
Your nurse will talk you through exactly what's involved and what to expect during your consultation.
How long do results last?
+
This varies from person to person and is discussed at your consultation.
