Does a Night Guard Really Help with TMJ?

Editor’s Note: This article was originally published on March 9, 2024, and has been updated in August 2025 to include the latest research and recommendations on TMJ disorder and night guard use.

Yes — a custom night guard can help relieve many TMJ (temporomandibular joint) symptoms by reducing jaw strain, protecting teeth from grinding, and promoting better alignment while you sleep. Although night guards don’t cure TMJ disorder, they are one of the most common first-line treatments recommended by dentists for jaw pain, clenching, and related discomfort.

In this guide, we’ll explain how night guards work for TMJ pain, who they help most, and when additional treatment may be needed.

Understanding TMJ Disorder

The temporomandibular joint (TMJ) connects your jawbone to your skull, allowing you to chew, speak, and yawn. TMJ disorder (TMD) occurs when this joint or the surrounding muscles become strained, often leading to jaw pain, stiffness, headaches, or clicking noises. Causes vary and can include arthritis, jaw injuries, or chronic teeth grinding (bruxism). Since bruxism is one of the most common triggers, night guards are frequently recommended as a first step in managing TMJ-related pain.

According to the Mayo Clinic, TMJ disorders can be caused by factors like arthritis, jaw injuries, or chronic teeth grinding (bruxism).

How Night Guards Help Manage TMJ Pain

Night guards, also called TMJ night guards, occlusal splints, or bite guards, can play an important role in managing TMJ disorder. These dental appliances fit over your teeth and are usually worn at night while you sleep. Their main job is to act as a barrier between your upper and lower teeth, preventing grinding and clenching.

By reducing teeth grinding and clenching, night guards ease the strain on your TMJ and jaw muscles. This can help relieve pain and discomfort caused by TMJ disorder.

They also protect your teeth from damage like wear, fractures, or enamel erosion caused by grinding. Although they don’t cure TMJ disorder, night guards are an effective way to manage symptoms and protect your smile.

Are night guards effective for all types of TMJ disorders?

Night guards can be effective for various types of TMJ disorders, but their efficacy may vary depending on the specific condition and underlying causes. Night guards are typically recommended for TMJ disorders characterized by teeth grinding (bruxism) or jaw clenching during sleep, as these behaviors can exacerbate TMJ symptoms.

However, for individuals with structural issues in the temporomandibular joint or severe cases of TMJ disorder, night guards alone may not be sufficient for symptom management. In such cases, a comprehensive treatment approach that may include night guards along with other interventions, such as physical therapy, stress management techniques, or medication, may be necessary. It’s important for individuals experiencing TMJ symptoms to consult with a dental professional or healthcare provider for a proper diagnosis and personalized treatment plan tailored to their specific needs.

How do I know if I need a custom-fitted night guard or if an over-the-counter option will suffice?

Custom vs OTC Night Guards for TMJ

Not all night guards are created equal. Here’s how over-the-counter (OTC) options stack up against custom-fit guards:

💡 Key takeaway: OTC guards may help in mild cases, but for lasting TMJ relief, a custom guard is the safest and most effective option. Sentinel delivers dentist-quality guards directly to your door — at a fraction of the cost.

Can wearing a night guard worsen my TMJ symptoms in the long run?

While night guards are generally considered a safe and effective treatment for TMJ disorder, there is a potential risk that wearing a night guard could worsen TMJ symptoms in some cases. This is more likely to occur if the night guard is not properly fitted or if it alters the alignment of the jaw or teeth in a way that exacerbates TMJ-related issues. For example, if the night guard is too bulky or thick, it may interfere with the natural position of the jaw and exacerbate muscle tension or discomfort over time.

Additionally, prolonged use of a night guard without addressing underlying causes of TMJ disorder, such as stress, teeth misalignment, or poor posture, may only provide temporary relief of symptoms without addressing the root cause. In such cases, TMJ symptoms may persist or worsen over time despite wearing a night guard.

It’s important to consult with a dental professional or healthcare provider if you experience any new or worsening symptoms while wearing a night guard. They can assess the fit and effectiveness of the night guard and provide recommendations for adjustments or alternative treatments if necessary. In some cases, a custom-fitted night guard or complementary therapies such as physical therapy or stress management techniques may be more appropriate for managing TMJ symptoms effectively in the long run.

Are There Risks or Side Effects of Wearing a Night Guard?

Night guards are generally safe, but some people may experience:

• Jaw soreness during the first few nights as your muscles adjust.

• Minor tooth shifting if the guard doesn’t fit properly.

• Gum irritation from a bulky or ill-fitting guard.

• Excess saliva at first, which usually subsides as you adapt.

💡 These risks are rare with custom-fit guards. Most issues come from OTC boil-and-bite versions that don’t provide even bite distribution or lasting comfort.

What Does the Research Say About Night Guards for TMJ?

Many studies have explored how effective night guards are for managing TMJ disorder, and overall, the results are encouraging.

✔️ Key findings include:
A systematic review published in the Saudi Dental Journal found that night guards can significantly reduce pain and improve jaw function for people with TMJ disorder.

Research shows that by preventing teeth grinding and reducing pressure on the jaw joint, night guards help relieve common TMJ symptoms like:

• Jaw pain

• Muscle tension

• Difficulty opening or closing the mouth

However, it’s important to note that some studies have limitations, such as:

• Small sample sizes

• Short follow-up periods

These factors can affect how widely the results apply. Despite this, the overall evidence supports night guards as an effective treatment option for many people with TMJ disorder.

Additionally, dental professionals agree that while night guards don’t cure TMJ, they play a valuable role in a comprehensive treatment plan, especially when combined with other therapies like physical therapy, stress management, or dental adjustments.

✔️ Key takeaway:
Scientific studies and expert opinions support using night guards to reduce TMJ pain and protect your jaw health, especially when fitted properly and used alongside other recommended treatments.

Benefits of Using Night Guards for TMJ

Wearing a night guard offers several important benefits for people with TMJ disorder.

✅ 1. Reduces pain and discomfort
Night guards cushion the impact of teeth grinding and clenching, easing strain on the jaw joint and surrounding muscles. This helps relieve common TMJ symptoms like jaw pain, stiffness, and tension.

✅ 2. Protects your teeth
By preventing grinding damage, night guards help preserve your teeth and reduce the risk of:

• Tooth wear

• Chips or fractures

• Enamel erosion

✅ 3. Improves sleep quality
Less jaw pain and tension mean fewer sleep disruptions, allowing you to wake up feeling more rested.

✅ 4. Promotes jaw muscle relaxation
Night guards help keep your jaw in a relaxed position, reducing tightness and discomfort overnight.

✔️ Key takeaway:
Using a night guard for TMJ not only reduces pain but also protects your teeth, improves sleep, and enhances your overall quality of life.

Night guards provide a cushioning effect that absorbs the forces generated by teeth grinding and clenching, thereby minimizing strain on the temporomandibular joint and surrounding muscles. 

Will wearing a night guard eliminate the need for other treatments, such as physical therapy or medication, for TMJ disorder?

While wearing a night guard can be an effective treatment for managing TMJ disorder, it may not eliminate the need for other treatments such as physical therapy or medication in all cases. The effectiveness of night guards varies depending on the severity and underlying causes of TMJ disorder, as well as individual factors such as lifestyle and overall health.

For some individuals, wearing a night guard alone may provide sufficient relief from TMJ symptoms, especially if the primary cause is teeth grinding or clenching. However, for others, a multifaceted approach that combines various treatments may be necessary to achieve optimal results.

Physical therapy techniques, such as jaw exercises, stretches, and manual therapy, can help improve jaw mobility, reduce muscle tension, and alleviate pain associated with TMJ disorder. Additionally, stress management techniques, relaxation therapies, and lifestyle modifications may play a crucial role in reducing stress and tension in the jaw muscles, thereby complementing the effects of a night guard.

In some cases, medication such as muscle relaxants, pain relievers, or anti-inflammatory drugs may be prescribed to manage TMJ-related pain and inflammation. These medications can provide temporary relief from symptoms but are typically used in conjunction with other treatments rather than as standalone therapies.

Ultimately, the most effective treatment approach for TMJ disorder will vary depending on individual circumstances. It’s essential to work with a healthcare provider or dental professional to develop a comprehensive treatment plan tailored to your specific needs, which may include a combination of treatments such as wearing a night guard, physical therapy, medication, and lifestyle modifications to effectively manage TMJ symptoms and improve overall quality of life.

Alternative Treatments for TMJ

While night guards can significantly reduce TMJ pain, many people find the best results by combining them with other approaches. Common complementary treatments include:

• Physical therapy – gentle jaw exercises and stretches improve mobility and reduce tension.

• Stress management – techniques like mindfulness, yoga, or therapy help lower jaw clenching.

• Lifestyle adjustments – avoiding hard foods, improving posture, and practicing relaxation.

• Medical treatments – in severe cases, injections or other dental interventions may be recommended.

Together with a properly fitted night guard, these strategies can provide more comprehensive and lasting relief from TMJ symptoms.

Practical Tips for Night Guard Users

To get the most out of your night guard:

• Clean daily with a soft toothbrush and non-abrasive toothpaste.

• Store properly in a clean, dry container to prevent bacteria growth.

• Check regularly for cracks or changes in fit.

• Adjust gradually to wearing it by increasing usage time each night.

• Follow up with your dentist to ensure your guard fits well and your TMJ symptoms are managed effectively.

Taking care of your night guard ensures comfort, durability, and the best results for your TMJ relief.

Conclusion

Night guards are an effective tool for managing TMJ symptoms like jaw pain and teeth grinding. While they don’t cure TMJ disorder, they help protect your teeth and reduce strain on your jaw joints and muscles.

Research and dental experts support night guards as part of a comprehensive TMJ treatment plan. However, they’re not suitable for everyone. Always consult your dentist to find the best solution for your needs.

With proper care and by combining your night guard with other therapies, you can achieve lasting relief and improve your overall quality of life.
