Jaw clenching and teeth grinding (known medically as bruxism) is one of those things that a surprising number of people don't even realise they have. You might wake up with a sore jaw, a dull headache, or tension in your neck and shoulders. Your dentist might have mentioned your teeth are showing signs of wear. Or maybe you've caught yourself clenching during a stressful meeting without even realising it.
It's also one of the most common reasons people reach out to Contour Aesthetics, particularly when symptoms begin affecting day-to-day comfort
Common signs you might be clenching or grinding:
* Waking up with a sore, tight jaw
* Worn or sensitive teeth
* Dull morning headaches
* Neck, shoulder or temple tension
* Clicking or popping in your jaw joint
* Ear ache with no infection
If a few of these ring a bell, it's worth having a conversation. A consultation with a qualified health practitioner can help determine appropriate management options. Book here
Q U E S T I O N 01
So what exactly is bruxism, and how common is it really?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
Bruxism is basically the medical term for grinding or clenching your teeth, and it's far more common than people think. Research suggests it affects around one in five adults, although honestly I'd say the number is probably higher because so many people have no idea they're doing it. A lot of grinding happens at night during sleep, so you might only notice the knock-on effects: the jaw pain, the headaches, the tired-looking muscles.
There's also daytime clenching, which tends to be stress-driven. You might clench when you're concentrating hard, stuck in traffic, or in a tense work situation. Most people don't notice until they've been doing it for a while and their jaw starts aching, or their dentist flags it.
Q U E S T I O N 02
What management options may help with jaw clenching?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
Great question, and you're right that dentistry is often the first port of call. This is usually in the form of a night guard or splint. Those absolutely have a role, especially in protecting your teeth. But they don't actually address the muscle activity causing the problem. That's where an individual assessment is necessary.
The masseter is the main muscle responsible for chewing and clenching. It sits on the side of your jaw, just in front of your ears. Certain clinician-led approaches may help reduce excessive muscle activity where clinically appropriate. You can still chew, talk, and laugh. All of that is completely unaffected. But for some patients, the unconscious, forceful clenching and grinding is reduced.
It's not an either/or situation:
'Think of it like this: a night guard protects your teeth from the grinding. Clinical treatments may help address the muscle activity contributing to the symptoms. Both have a role.'
Q U E S T I O N 03
What does the treatment actually involve? Is it scary? Does it hurt?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
Hand on heart it's one of the more straightforward treatments I do. If treatment is appropriate, the process, risks and aftercare are all explained in person. The whole thing takes about ten minutes once we're ready to go.
Pain-wise, most people describe it as a small pinch (nothing close to what they were expecting). The masseter is a reasonably accessible muscle so there's no deep or uncomfortable poking around. Some people are a bit apprehensive beforehand, but they're almost always surprised by how quick and simple it is.
No anaesthetic is needed, there's no downtime, and you can drive yourself home and get on with your day immediately. I usually suggest avoiding anything really chewy for the rest of that day, like dense bread, tough meat, that sort of thing. Just to let the muscle settle.
Q U E S T I O N 04
When will I notice a difference? And how long does it last?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
Most people start noticing less jaw tension and tightness within the first week. The full effect builds over two to four weeks as the muscle gradually relaxes and settles. For people with significant morning headaches or jaw pain, that relief often kicks in faster than they expect.
Treatments can lasts three to six months, depending on the individual. A few things influence this: how active the muscle was to begin with, the dose used, and your own metabolism. People who come back for repeat treatments often get longer-lasting results over time, because the muscle progressively reduces in its activity and size between treatments.
The first time is often the shortest-lasting, which is completely normal. Once your body and the treatment find their rhythm, results tend to extend. Most of my regular jaw clenching patients come in every four to six months and many report that managing jaw tension can improve day to day comfort.
Q U E S T I O N 05
Will it affect my ability to chew or eat normally? That's my biggest worry.
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
This is genuinely the question I get asked most, and the answer is: no, not when it's done well. The masseter is a powerful muscle, and the amounts we use are specifically dosed to reduce the excessive, forceful clenching activity. The intention is not to weaken the muscle to the point where normal function is affected.
You'll still be able to eat, chew, speak, yawn, and smile completely normally. In practice, most people notice they can chew more comfortably after treatment, because the muscle is no longer constantly fatigued and overworked.
That said, this is exactly why the skill and experience of your practitioner matters enormously. The dose, the technique, and the placement all play a role. I always start conservatively, assess at four weeks, and adjust from there.
Q U E S T I O N 06
Can jaw muscle activity affect facial shape?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
It's true. When the masseter has been chronically overworked through clenching, it often becomes enlarged, which can make the lower face look wider, squarer, or heavier than it naturally would. However, as the muscle relaxes, facial changes vary significantly between individuals and should not be assumed.
For most people who come to me for jaw clenching relief, any aesthetic considerations will need to be discussed carefully during consultation. But it's worth knowing about (especially if you've noticed your jaw has become more pronounced over the years). Chronic bruxism is often the culprit.
Whether it's a good or bad thing depends entirely on your starting point. If you already have a naturally slim face, I'd adjust the approach accordingly. That's part of why a proper consultation is so important.
Q U E S T I O N 07
Is it safe? Are there any side effects I should know about?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
As with any clinical procedure, risks and side effects exist, and suitability varies between individuals. Research into masseter muscle treatment for jaw clenching is genuinely promising. Most studies show reductions in clenching activity, jaw pain, and bite force. That said, the evidence is still developing and researchers themselves note that larger, more standardised studies are needed. Individual responses vary, although some patients report meaningful improvement in symptoms.
Some mild tenderness or bruising at the injection site is possible. Occasionally people notice some temporary jaw fatigue or a mild ache in the first day or two as the muscle adjusts. This settles on its own.
Serious complications are rare when the treatment is performed correctly. The main risks come from incorrect placement or dosing, which is why choosing a practitioner who genuinely understands facial anatomy matters.
If you have any neuromuscular conditions or take certain medications, we'll discuss that at your complementary consultation before proceeding.
Q U E S T I O N 08
I'm stressed, and I think that's causing my clenching. Will this fix the problem or just mask it?
MEGAN DEANS: Registered Cosmetic Nurse, Contour Aesthetics
Honest answer: It doesn't address the root cause if stress is driving your clenching. If you're going through a difficult time, working on that through whatever means works for you. Exercise, therapy, sleep, and reducing workload is absolutely part of the picture.
But what the treatment does very effectively is interrupt the physical cycle of muscle overuse. Even when stress continues, the muscle can't contract with the same force. The damage to your teeth is reduced, the jaw pain and headaches are reduced, and many patients actually feel less stressed because they're not waking up exhausted with a sore face every day.
It's not one or the other. Think of it as managing the physical consequences while you address the underlying cause.
Q U E S T I O N 09
Do I need a referral? Or do I just book in with you directly?
MEGAN DEANS — Registered Cosmetic Nurse, Contour Aesthetics
No referral needed. You can book a free consultation directly through our website. At the consultation, we'll chat through your symptoms, go over your health history, discuss what treatment would look like for you specifically, and I'll answer any questions you have. There's absolutely no obligation to proceed on the day.
If your dentist has flagged bruxism and you'd like to share any notes with me, that's always helpful context, but it's not a requirement. Everything gets assessed fresh at consultation.
I do recommend that people with suspected bruxism also maintain their dental care alongside any treatment with me. We're approaching the problem from different angles and both have a role to play.
