Face Concerns

Teeth Grinding and Jaw Tension

Teeth grinding and jaw clenching are more common than many people realise, and the effects go beyond dental wear. Persistent jaw tension can cause headaches, facial pain and disrupted sleep. Botulinum toxin injections offer an effective solution, reducing muscle activity, relieving discomfort and improving the appearance of the lower face.

UNDERSTANDING THE CONCERN

What is Bruxism

Bruxism, the grinding or clenching of teeth, is extremely common, particularly in people under stress, and often occurs during sleep without the individual being aware. Over time it causes significant wear on the teeth, jaw pain, headaches and muscle fatigue, and can widen the lower face by causing the masseter muscles to hypertrophy.

When it is overworked through chronic clenching, it thickens and enlarges, squaring the jawline and sometimes creating discomfort that patients assume is dental or skeletal in origin. Our guide to Masseter Botox explains how the treatment calms that overactivity and what to expect week by week.

Signs your jaw muscle may be overworking

Waking with jaw pain, headaches or facial tension

A jaw that feels tight or tired by the end of the day

Teeth that have become worn, chipped or sensitive over time

A square or wide lower face caused by enlarged jaw muscles

Clenching or grinding that your dentist has flagged

Headaches that seem to originate from the jaw or temples

Discomfort when chewing or opening the mouth wide

Treatments for this concern

Recommended Treatments

Botulinum toxin injected into the masseter muscle is a well-established and effective treatment for bruxism and jaw tension. This is the treatment we use.

Treatment

Masseter Botox

Precise botulinum toxin injections into the masseter muscle reduce involuntary clenching and grinding, relieving associated pain and tension. Results become apparent within two to three weeks and last between four and six months. A secondary benefit is a gradual slimming of the lower face profile as the muscle volume reduces over repeated treatments.
