Temporomandibular joint disorder (TMJ) is a condition that affects the jaw joint and muscles surrounding it. It can cause pain, discomfort, and difficulty in jaw movement. One potential solution to alleviate TMJ symptoms is the use of a mouthguard. In this article, we will explore the effectiveness of mouthguards in managing TMJ from various perspectives.

1. Alignment and Stability

Mouthguards can help with TMJ by promoting proper alignment and stability of the jaw. They provide a cushioning effect that reduces pressure on the joint, allowing the jaw to rest in a more relaxed position. This can help alleviate pain and prevent further damage to the joint.

Mouthguards can also help stabilize the jaw by providing a barrier between the upper and lower teeth. This prevents excessive grinding or clenching, which are common habits associated with TMJ. By reducing these habits, mouthguards can help minimize strain on the joint and muscles.

2. Muscle Relaxation

Mouthguards can aid in muscle relaxation, particularly for individuals who clench their teeth during sleep. They create a physical barrier that prevents the upper and lower teeth from coming into direct contact, reducing muscle tension. This relaxation can alleviate TMJ symptoms such as jaw pain and headaches.

Additionally, some mouthguards are designed with special features such as heat or cold therapy. These features can further promote muscle relaxation by applying gentle heat or cold to the jaw area, soothing the muscles and reducing inflammation.

3. Protection against Bruxism

Bruxism, or teeth grinding, is a common symptom of TMJ. Mouthguards can act as a protective barrier between the teeth, preventing excessive wear and damage caused by grinding. By cushioning the impact of grinding, mouthguards can help reduce the risk of tooth fractures and other dental complications associated with TMJ.

4. Stress Reduction

Stress is a known trigger for TMJ symptoms. Mouthguards can help manage TMJ by reducing stress and anxiety levels. The act of wearing a mouthguard can serve as a reminder to relax the jaw and avoid clenching or grinding. This conscious effort to relax can help break the cycle of stress-induced TMJ symptoms.

Furthermore, some mouthguards are designed with additional features such as aromatherapy or relaxation techniques. These features can help create a calming effect, reducing stress and promoting overall well-being.

5. Improved Sleep Quality

TMJ can significantly impact sleep quality due to pain and discomfort. Mouthguards can improve sleep quality by reducing TMJ symptoms during sleep. By providing a cushioning effect and preventing teeth grinding, mouthguards can alleviate pain and promote better sleep.

Improved sleep quality can have a positive impact on overall health and well-being. It can also help reduce daytime fatigue and enhance cognitive function.

6. Customization and Fit

Mouthguards can be customized to fit an individual’s specific jaw structure and bite. This ensures optimal comfort and effectiveness in managing TMJ. Customized mouthguards are typically made by dental professionals and provide a better fit compared to over-the-counter options.

A well-fitted mouthguard will stay in place during sleep and allow for natural jaw movement. It should not cause discomfort or interfere with breathing. The customization process may involve taking impressions of the teeth and jaw to create a personalized mouthguard that suits the individual’s needs.


Mouthguards can be a valuable tool in managing TMJ symptoms. They provide alignment, stability, muscle relaxation, protection against bruxism, stress reduction, improved sleep quality, and customization for optimal fit. However, it is important to consult with a dental professional to determine the most suitable mouthguard for individual needs. Mouthguards should be used in conjunction with other TMJ management strategies, such as jaw exercises and stress reduction techniques, for comprehensive care.
