Relieve jaw pain, protect your teeth, and reduce clenching — with precise muscle relaxing injections at Fluid Medical.
Treatment for the masseter muscles is a safe and effective treatment for people who experience teeth grinding (bruxism), jaw clenching, or tension-related jaw pain. The masseters are large chewing muscles on either side of the jaw. When they are overactive — often due to stress, sleep bruxism, or habitual clenching — they can cause tooth wear, jaw pain, headaches, and even a widened, square jawline.
By injecting small amounts directly into the masseter muscles, we temporarily relax their activity. This reduces the force of clenching and grinding, helping to relieve pain, protect the teeth, and decrease muscle bulk over time, which can create a slimmer, more tapered jawline.
Effects appear within 1–2 weeks, lasting about 3–4 months. With repeated treatments, the masseters often continue to shrink slightly, and symptoms of clenching and grinding tend to become milder.
Teeth grinding and jaw clenching — collectively known as bruxism — affect far more people than realise it. Often occurring during sleep, bruxism can cause significant dental damage, chronic jaw pain, and persistent headaches over time. At Fluid Medical, we offer a clinically effective, non-surgical injectable treatment that directly targets the muscles responsible — providing lasting functional relief and, as a secondary benefit, a slimmer and more refined jawline.
Bruxism is driven by overactivity of the masseter muscles — the large, powerful chewing muscles located on either side of the jaw. When these muscles are chronically overactive — whether from stress, anxiety, sleep-related habits, or habitual daytime clenching — they contract with far greater force and frequency than the jaw needs for normal function.
Over time, this persistent overactivity causes:
Small, precise amounts of purified protein are injected directly into the masseter muscles on each side of the jaw, temporarily reducing their contractile activity. With reduced muscle force, the intensity of grinding and clenching decreases significantly — relieving the pressure on the teeth, jaw joint, and surrounding tissues.
Functional improvement is typically the first change patients notice — reduced jaw tension, less morning soreness, and fewer tension headaches — followed by a gradual reduction in masseter bulk over the weeks that follow as the muscle is used less forcefully.
One of the notable secondary effects of masseter treatment is aesthetic. As the masseter muscle reduces in bulk with repeated treatment, the lower face gradually slims and tapers — softening a wide or square jawline and creating a more defined facial contour.
For patients whose primary concern is bruxism, this aesthetic benefit is a welcome addition. For patients seeking jawline slimming, the functional relief from reduced clenching is equally valuable. Many patients come for one benefit and appreciate both.
Effects begin to develop within one to two weeks as the masseter muscles relax. Results typically last three to four months, after which muscle activity gradually returns and a repeat treatment is needed to maintain the effect.
With consistent treatment over time, the masseter muscles often continue to reduce progressively in size — meaning both the functional relief and the aesthetic slimming compound with each session. Many patients find that symptoms of grinding and clenching become milder with each treatment cycle.
A two-week review is offered following treatment to assess the result and make any refinements if needed.
Masseter treatment for bruxism is suitable for patients who:
A full clinical and facial assessment is conducted before treatment to confirm masseter overactivity and guide precise, symmetrical dosing for your individual jaw anatomy.
The masseter is a powerful, dense muscle requiring careful assessment of size, activity, and symmetry before treatment. At Fluid Medical, all injections are administered by qualified doctors with detailed anatomical knowledge — ensuring accurate placement, symmetrical results, and appropriate dosing for both functional relief and aesthetic refinement.
Treatment is never one-size-fits-all. Your jaw anatomy, symptom severity, and goals determine the entire approach.
