Masseter muscle pain can feel like a dull ache in your jaw, a tightness when opening your jaw, or cause headaches you can’t shake. If you’re someone who grinds their teeth at night or clenches during the day (especially when stressed), you might not even realise how much pressure your jaw is under, until it starts to manifest as pain.
At Define Laser, we often help patients who are looking for relief from jaw tension and facial discomfort or wanting to change the appearance of a broad lower face caused by enlarged masseter muscles. While this can be uncomfortable, there are medical treatment options available to help relax these muscles, depending on your individual needs and clinical history.
Understanding masseter muscle pain and its symptoms
The masseters are located on either side of your jaw and play a major role in chewing and biting. When they become overactive, either from frequent teeth grinding (bruxism) or habitual jaw clenching, they can become enlarged, tight, and sore.
The symptoms of masseter muscle pain often include:
- Jaw or temple pain (especially on waking)
- Clicking or stiffness in the jaw joint
- Chronic tension headaches or migraines
- Tooth wear or enamel damage
- A square or heavy appearance in the lower face
Many people don’t connect their headaches or facial tension to their jaw muscles, which is why masseter muscle pain can go undiagnosed for months or even years.
How to relax masseter muscles
One approach used by qualified medical professionals to address this issue involves the targeted relaxation of the masseter muscles using prescription-only muscle relaxants. These are administered via a small injection into the masseter area, with the goal of reducing excessive muscle activity while preserving function.
This treatment must be prescribed and administered by a qualified healthcare practitioner, like Define Laser’s Dr Lindsay Watson. It is not suitable for everyone and should only be considered following a personalised consultation.
How does relaxing the masseter muscle ease pain?
The active compound used is designed to temporarily block signals between the nerves and muscles, reducing contraction strength in the masseter without fully deactivating the muscle. This often results in:
- Relief from clenching and tension
- A reduction in morning jaw soreness or stiffness
- Cosmetic changes, including a slimmer or more contoured jawline (in some cases)
Will treatment affect normal jaw function?
This is one of the most common concerns people have about masseter muscle treatment, and it’s completely understandable. When administered properly by an experienced practitioner, you should maintain your ability to chew, smile, and speak normally. The goal is to reduce excessive muscle tension and pain, not to compromise your jaw’s essential functions.
In some cases of TMJ (temporomandibular joint) pain, jaw movement can improve because the tension and pain of opening the mouth is eased. However, outcomes can vary, and side effects (such as mild jaw weakness or tenderness) can occur. That’s why it’s essential to choose a provider who has extensive experience in this area.
How long does it take to feel jaw tension pain relief?
If you decide to pursue professional treatment for your masseter muscle pain, you may begin to feel a reduction in tension after 7 to 14 days, with full effects noticeable by around 3 to 4 weeks.
Results typically last several months, depending on individual response, muscle strength, and lifestyle factors like stress or nighttime grinding.
Can relaxing masseter muscles improve your jawline?
Yes, for some patients, relaxing the masseter muscles results in a softer or more tapered facial contour. While this is not the primary reason most people seek treatment, it is a recognised cosmetic outcome and can be discussed during your consultation.
For those seeking cosmetic refinement, visible changes to the jawline may occur over time as jaw muscles subtly decreases in size.
