Jaw & Clenching
Masseter Botox in Waterloo Region
Botox for the muscle at the back of your jaw, whether you want a softer lower face or you are tired of clenching. $9 a unit, placed by a Nurse Practitioner in St. Jacobs.
The masseter is the muscle at the back of your jaw, the one you can feel move when you bite down. Like any muscle, it gets bigger with use, and clenching uses it a lot. A lot of people find out from their dentist, who sees the wear on the teeth before anything shows up in the mirror. Others come to us because their lower face has squared off. The treatment is the same either way, and it is not the same as the Botox you would have in your forehead.
WHAT THE MASSETER DOES
A neuromodulator like Botox, placed into the masseter, relaxes it, so the muscle does less work and gradually reduces in size. The lower face softens and the jawline reads narrower from the front.
Most people feel the muscle start to relax in three to five days, and the full effect is there by about three weeks. Some slimming shows up right away, and it keeps building the longer you maintain it.
IF YOU CLENCH OR GRIND
A lot of people come in for the masseter because they clench. Sometimes a dentist has flagged it, and sometimes they have been waking up with a tight jaw or wearing through a night guard for years.
Relaxing the masseter reduces how hard the muscle can contract, which takes some of the force out of the clench. It does not stop the habit, and it is not a treatment for the jaw joint itself, so if something is going on inside the joint that is a conversation for your dentist or physician first.
WHAT IT COSTS
Masseter Botox at Bonita is $9 a unit, a little under our $9.50 rate for cosmetic areas like the forehead and the 11s.
The masseter takes 15 to 25 units per side. Both sides are treated, so a full treatment is 30 to 50 units.
| Units | Cost | |
|---|---|---|
| Lighter dose, both sides | 30 units | $270 |
| Typical, both sides | 40 units | $360 |
| Stronger dose, both sides | 50 units | $450 |
Your specific dose will depend on how strong the muscle is, which Jessica assesses in person rather than from a photo.
The consultation is $50 and comes off your treatment, same day or when you decide to move forward. If a two week follow-up is needed, they are complimentary apart from any additional units.
-
Masseter Botox lasts longer than cosmetic Botox. Where the forehead and the 11s usually run three to five months, the masseter typically holds for five to six, because the muscle is larger and the dose is higher. Most people end up on two treatments a year rather than three or four.
If you keep it up, each round tends to need a little less than the one before, because the muscle does not fully rebuild between treatments.
-
The injections take a few minutes, two to three small ones on each side, into the thickest part of the muscle. It is a deeper injection than a forehead treatment, so most people feel pressure rather than sting.
You can go back to your day straight after. Chewing can feel tired for the first week or two while the muscle adjusts, particularly with tougher food, and that settles on its own.
We see you again at two weeks if anything needs adjusting, and that visit is complimentary.
WHEN IS IT NOT THE RIGHT TREATMENT?
Masseter Botox does not suit everyone. If the fullness in your lower face comes from fat or skin rather than muscle, relaxing the muscle will not change it, and if your face is already narrow, taking volume out of the lower third can read as hollow rather than defined.
Jessica will tell you at the consultation if she does not think this will be an effective treatment for you.
FREQUENTLY ASKED QUESTIONS

$9 a unit, which is a little under our $9.50 rate for cosmetic areas. The masseter takes 15 to 25 units per side, so a full treatment of both sides is 30 to 50 units, which comes to $270 to $450 depending on how strong the muscle is.
-
At $9 a unit, 20 units is $180. That would usually cover one side, or a lighter dose across both. Most people need 15 to 25 units per side.
-
15 to 25 per side. Stronger, more developed muscles need more. Jessica assesses it by feeling the muscle while you clench, which is why this one needs an in-person consultation rather than an estimate over email.
-
No. OHIP does not cover masseter injections, whether the reason is cosmetic or jaw related.
-
Generally not. Masseter injections for jaw clenching or facial slimming are not an approved indication in Canada, so most extended health plans decline them. Worth checking your own plan before you assume either way.
-
Yes, and it is a common reason people come in. Relaxing the muscle reduces how hard you can clench. It is not a treatment for the jaw joint itself and it does not replace a night guard if your dentist has recommended one, so it works alongside what you are already doing.
-
That risk comes from too much product, or from product placed too low and too far forward, so the muscles that support the lower face are affected as well. Staying in the thickest part of the muscle and dosing conservatively is what prevents it. If you already have significant skin laxity, Jessica will raise it at the consultation rather than afterwards.That risk comes from too much product, or from product placed too low and too far forward, so the muscles that support the lower face are affected as well.

-
Five to six months on average, which is longer than cosmetic Botox in the upper face. Most people come twice a year.
-
The muscle starts relaxing in three to five days and the full effect is there by about three weeks. Some slimming is visible right away, and it keeps building the longer you maintain the treatment.
-
It is a deeper injection than a forehead treatment, so you feel more pressure than sting. Two to three injections per side and it is over in a few minutes.
-
Temporary tenderness or a small bruise where the needle went in. Chewing can feel tired for a week or two, especially with tough or chewy food. Less commonly, asymmetry or an uneven smile if placement is off, which is the reason to care who is injecting you.
-
Your smile should not change, because the muscles that control it are different and sit higher. Chewing power is reduced on purpose, which is the point of the treatment, but not to the extent that normal eating is affected. Tough steak and hard bagels are what people notice in the first couple of weeks.

Jessica Caceres, a Nurse Practitioner and the owner of the clinic, places every injection at Bonita. We are in St. Jacobs, in Waterloo Region, about fifteen minutes from uptown Waterloo and twenty from downtown Kitchener.
Botox for the forehead, the 11s and crow's feet is on the injectables page.
