Tension in the jaw, especially from overactive masseter muscles, is more common than many realise. Whether it shows up as clenching, headaches, or facial tightness, the underlying issue often involves these powerful chewing muscles working harder than they need to.

Why Masseters Become Overactive

The masseter muscles are located at the sides of the jaw and play a crucial role in chewing and speaking. When they become overactive, it is usually due to:

Bruxism: Involuntary teeth grinding, often during sleep
Jaw clenching: A subconscious response to stress or concentration
Chronic tension: Linked to posture, sleep quality, and lifestyle factors

Over time, these habits can cause discomfort, facial tension, and in some cases, enlargement of the masseter muscles.

Two Common Treatment Pathways

Depending on the severity and cause of symptoms, different treatments may be appropriate. Two options frequently considered in clinical settings are:

1. Night Splints

Custom-fitted dental splints are designed to be worn during sleep. These can help protect teeth from grinding and may reduce muscle overuse by creating a physical barrier. For many people, this option forms part of a broader management plan that includes stress management, physiotherapy, or changes in posture and sleep habits.

Night splints are non-invasive and reversible, and they are often recommended as a first-line strategy for those with bruxism or mild muscle tension.

2. Injectable Muscle Relaxants for the Masseter

When symptoms persist or are more severe, muscle-relaxant injections may be considered. These are used to temporarily reduce the strength of muscle contractions, which can provide relief from clenching, jaw tension, and associated discomfort.

This treatment is sometimes recommended where splints have not provided sufficient relief or where muscle bulk is contributing to functional or aesthetic concerns. While not suitable for everyone, it may offer a non-surgical alternative for managing chronic muscle overactivity.

As with all medical procedures, there are potential side effects and not all patients will respond the same way. A consultation with a qualified medical practitioner is essential to determine whether this is a suitable option.
