How Nightguards and Splints Can Ease TMJ Pain


Temporomandibular joint disorder (TMJ) or temporomandibular disorder (TMD) is a condition that affects the jaw joint and surrounding muscles, leading to discomfort and pain. One of the common causes of TMJ pain is teeth clenching and grinding, also known as bruxism. Many individuals unknowingly clench or grind their teeth, especially during sleep, which can exacerbate TMJ symptoms.

Nightguards and splints are dental appliances designed to protect the teeth and alleviate TMJ pain caused by bruxism. In this article, we will explore the use of nightguards and splints and how they can effectively ease TMJ discomfort and promote better oral health.

Understanding Bruxism and its Impact on TMJ:

Bruxism is a habitual parafunctional activity where an individual clenches or grinds their teeth, often unconsciously. It can occur during the day or night, but sleep bruxism is particularly problematic for TMJ health. The excessive force exerted on the teeth and jaw during bruxism can lead to muscle tension, jaw joint irritation, and dental damage, contributing to TMJ pain and discomfort.

The Role of Nightguards and Splints:

Nightguards and splints are customized dental appliances prescribed by dentists to address bruxism and its impact on TMJ health. They serve different functions but share the common goal of protecting teeth and alleviating TMJ discomfort caused by clenching and grinding.

  1. Nightguards: Nightguards, also known as occlusal splints or bite guards, are worn during sleep to create a barrier between the upper and lower teeth. They provide a cushioning effect that absorbs the forces generated during bruxism, reducing the impact on the teeth and TMJ.

Benefits of Nightguards:

  • Protect Teeth: Nightguards prevent tooth wear, chipping, and fractures caused by bruxism, preserving dental health and integrity.
  • Reduce TMJ Strain: By minimizing the impact of teeth clenching and grinding, nightguards help reduce strain on the TMJ and related muscles, leading to decreased TMJ discomfort.
  1. Splints: Splints, also referred to as stabilization splints or TMJ splints, are designed to stabilize the jaw joint and improve its alignment. They are typically used for individuals with more severe TMJ issues or those with a history of jaw joint dysfunction.

Benefits of Splints:

  • TMJ Alignment: Splints are specially designed to encourage proper jaw alignment, reducing joint irritation and promoting optimal TMJ function.
  • Reduce Muscle Tension: By aligning the jaw correctly, splints help relax the muscles around the jaw area, reducing muscle tension and discomfort.

The Customization Process:

Both nightguards and splints are custom-made for each individual to ensure an optimal fit and effectiveness. The process involves:

  1. Consultation: A dentist evaluates the individual’s TMJ health, dental history, and symptoms to determine the appropriate type of appliance needed.
  2. Impression: An impression of the teeth and jaw is taken to create a custom mold for the nightguard or splint.
  3. Fabrication: The nightguard or splint is fabricated in a dental laboratory based on the impression.
  4. Fitting: Once ready, the dentist fits the nightguard or splint to ensure comfort and proper function.


Nightguards and splints are valuable tools for protecting teeth and easing TMJ pain caused by bruxism. By providing a cushioning effect and promoting proper jaw alignment, these dental appliances help reduce the impact of teeth clenching and grinding on the TMJ. If you experience TMJ discomfort or suspect bruxism, consult a dentist experienced in TMJ disorders to discuss the possibility of using nightguards or splints. With their assistance and the use of these custom-made dental appliances, you can enjoy better oral health, reduced TMJ pain, and improved overall well-being.
