Jaw & Muscle · Stouffville, ON

Unclench your jaw. Protect your teeth.

Grinding, clenching and TMJ pain come from one overworked muscle. Relaxing the masseter with precise Botox eases the pain, spares your teeth, and can soften a bulky jawline at the same time.

The short answer

Jaw clenching, teeth grinding and TMJ pain respond very well to masseter Botox (relaxing the jaw muscle so it can’t clench as hard. It relieves pain, protects the teeth, and can slim a bulky jaw. Here, injectables are genuinely the right tool), and we say so because they actually treat the muscle causing it.

Understanding the condition

What are TMJ & bruxism?

Bruxism is the habit of clenching or grinding the teeth, often unconsciously, and often at night. Over time it overworks the masseter, the powerful muscle at the angle of the jaw. That can lead to TMJ disorder: jaw pain and stiffness, tension headaches, worn or cracked teeth, and a squarer, bulkier lower face.

It’s frequently driven by stress and shows up as morning jaw soreness, headaches at the temples, or a dentist pointing out tooth wear. Because the root of the pain is muscle overactivity, calming that muscle is one of the most effective ways to break the cycle.

Step one

Signs it's your jaw muscle

TMJ and bruxism show up in more ways than just a sore jaw. If several of these sound familiar, masseter treatment is worth discussing at a consultation.

Our approach

How Seamless Health treats TMJ & grinding

This is a case where an injectable is genuinely the right treatment, so it leads. But it works best as part of a bigger picture, alongside your dentist and a look at the stress driving it.

Best for · pain, grinding & bulk

Masseter Botox

A precise dose of Botox into the masseter muscle partially relaxes it, so it can't clench or grind with full force. Pain and headaches ease, the teeth are protected, and a bulky jaw gradually softens. Delivered by our medical injectors.

Alongside · protects the result

Dental coordination

Botox reduces the force of grinding, but a custom night guard protects the teeth while the muscle settles. We coordinate with, or refer you to, your dentist so both sides of the problem are covered.

The root cause · every plan

Trigger & stress review

Clenching is often stress-driven. Part of a lasting result is recognising your triggers and habits, so the muscle stays calmer between treatments rather than fighting the Botox.

Bonus · for the right patient

Jawline slimming

For those with a heavy masseter from years of clenching, treatment doubles as subtle lower-face slimming, a genuine aesthetic benefit that comes from treating the medical problem, not a separate procedure.

The honest part

Botox helps the muscle, not the habit

Masseter Botox is highly effective, but it isn’t a cure for grinding itself. It reduces the force and the damage while the underlying drivers (stress, bite, sleep) are addressed. We’ll always treat it as one part of a plan with your dentist, not a standalone fix, and results are temporary, so it’s repeated a few times a year.

Common Questions

TMJ & grinding, answered

The questions patients, and search engines, ask most.

Botox is injected into the masseter, the large muscle that clenches the jaw. It partially relaxes the muscle so it can’t clench or grind as forcefully, which relieves jaw pain and tension headaches, reduces tooth wear, and can slim a bulky jawline. It treats the muscle overactivity, not the habit itself.

Masseter Botox typically lasts about 3 to 4 months, with effects starting within 1 to 2 weeks. Most people repeat treatment a few times a year, and the muscle often becomes less overactive over time with consistent treatment.

No. Botox reduces the force of clenching and grinding, but it works best alongside dental care such as a custom night guard. We treat the muscle and coordinate with, or refer you to, your dentist rather than replace them.

For people with a bulky, over-developed masseter from years of clenching, Botox gradually softens and slims the lower face. A welcome side effect for many. The change is subtle and reversible, since the muscle returns to normal if treatment stops.

It’s quick and well tolerated. The masseter is treated with a few small injections on each side; most people describe only a brief pinch, and there’s minimal downtime afterward.
