When considering getting the best mouthguard for jaw clenching, there are various important factors to look into. Nevertheless, the ideal mouthguards depend on the underlying cause and severity of the clenching, as some people have minor, moderate, or even severe clenching issues.

This article will help you to get the best mouthguards you can use for jaw clenching by exploring:

  • What jaw clenching is and how mouthguards can help alleviate the condition;
  • Top mouthguards used for jaw clenching;
  • How to choose the best mouthguard for jaw clenching;
  • Other ways you can manage jaw clenching.

Understanding Jaw Clenching

According to the American Academy of Oral Medicine, jaw clenching, also known as bruxism, refers to the strong and sustained contraction of the jaw muscles, causing the upper and lower teeth to come tightly together. This condition often involves a static and compressive force exerted by the jaw muscles, which results in constant pressure on the teeth.

Although jaw clenching is often used interchangeably with teeth grinding, they have some distinct differences.

Teeth grinding, which is also a form of bruxism, specifically refers to the act of forcefully rubbing or grinding teeth together. This movement mainly happens in a back-and-forth or side-to-side motion. Teeth grinding can occur during the day or, more commonly, during sleep.

From the above descriptions, you can see the distinct differences between jaw clenching and teeth grinding. In jaw clenching, the contractions from the jaw muscles force the upper and lower teeth to come together tightly. However, no grinding happens.

Although these two conditions can affect one simultaneously, jaw clenching is static, while teeth grinding involves movement. Nevertheless, these problems can be resolved using a good NTI night guard.

Factors Contributing to Jaw Clenching

There are numerous factors that may lead to jaw clenching, including:

  • Stress and anxiety: Psychological factors like stress and anxiety can trigger jaw clenching, as it can be a subconscious response to such psychological stressors.
  • Bite irregularities: An abnormal bite can cause the jaw to exert excessive pressure, leading to jaw clenching.
  • Sleep disorders: Sleep disorders like sleep apnea might increase the chances of developing jaw clenching.
  • Jaw injury: People that have experienced Jaw and muscle sprain/ strain (JAMSS) are at a high risk of developing jaw tension and clenching.
  • TMJ disorders: There is a strong connection between TMJ disorders and jaw clenching.

Symptoms of Jaw Clenching

Jaw clenching occurs when the upper and lower jaws come close together, exerting lots of pressure. In most cases, the most distinct symptom of jaw clenching is feeling pain. However, not all jaw clenching conditions cause pain to the individuals.

So, how else can you know that you have jaw clenching issues?

Here are some other symptoms to watch out for:

  • Teeth grinding or clenching sounds: Such sounds may be audible during sleep and may be noticed by someone else.
  • Tooth damage: Excessive jaw clenching has significant effects on your teeth, leading to wear and tear, chipping, and even causing fractures.
  • Morning jaw stiffness: Some individuals may experience stiffness within the jaw joints upon waking up. This might be a symptom of jaw clenching.
  • Facial fatigue: Continuous muscle contractions that lead to jaw clenching may lead to one getting a fatigued or tired-looking face.
  • Tooth sensitivity: Due to jaw clenching, grinding your teeth may lead to tooth sensitivity, especially to hot or cold stimuli.

It would be prudent to note that you don’t have to experience all these symptoms to know whether you have jaw clenching. If you get any of the symptoms above, it is recommended to consult with a dental professional for an accurate diagnosis.

Mouth Guards and Jaw Clenching: Exploring the Benefits

Mouthguards act as the first line of defense against jaw clenching. They offer a simple, non-invasive solution, helping the affected individuals alleviate the symptoms of jaw clenching.

Here are some of the ways having a mouthguard for jaw clenching can help:

  • Cushioning and protection: Mouthguards act as a barrier between the upper and lower sets of teeth. They prevent the teeth from grinding or clenching, and by cushioning the individual from such impacts, they help to prevent and reduce tooth damage.
  • Muscular relaxation: Mouthguards may also provide a stable and more comfortable position for the jaw to rest on, promoting muscular relaxation.
  • Temporomandibular Joint (TMJ) support: Mouthguards can provide support to the TMJ, which connects the jawbone to the skull. By creating a balanced and aligned bite, TMJ mouthguards reduce the strain on the TMJ, potentially alleviating TMJ disorders and associated pain.
  • Sleep quality improvement: Wearing a mouthguard can significantly improve sleep quality, especially for people that experience jaw clenching when they sleep. This can also be helpful to your partner, whose sleep cycle is not disturbed by the noises generated by teeth grinding.

Factors to Consider When Choosing Mouth Guards for Jaw Clenching

There are numerous types of mouthguards, all differing in their fit, style, and pricing, among other factors. By understanding these considerations, you can narrow down your list and find the most comfortable and effective mouthguard to help with jaw clenching issues.

Here are the top factors to consider when choosing a mouthguard for jaw clenching issues:


A good mouthguard should have a perfect fit in your mouth. It shouldn’t be too thick or bulky to create discomfort or too loose, making it difficult to keep in place.

Custom-fit models are ideal, as they ensure the mouthguard stays in place without causing any discomfort to you.


While most top-quality mouthguards are made of durable materials, others use cheaper plastic, which may not be long-lasting. Moreover, you should also consider going for products made of safe components and ensure they are BPA-free and latex-free.


Although comfort may be subjective, it is important to go for a product with the user in mind. Depending on your level of jaw clenching, you might get soft, moderately hard, or hard mouthguards. Moreover, to boost your comfort, you may have to consider a night guard with braces, especially if you are on orthodontic treatment.

Nevertheless, ensure they are multi-layered (with a soft interior and a hard exterior) to perfectly balance comfort and durability.

Ease of maintenance

Consider mouthguards that are easy to clean, use, and maintain. Consider any specific instructions for care and storage options provided by the brand. A mouthguard that is easy to clean and use ensures high hygiene standards and a prolonged lifespan.


Consider your budget before settling on a mouthguard brand. However, you should also consider other related factors, like the severity of your condition and customization requirements. People with severe jaw clenching may need to replace the mouthguards more often as they are prone to wear and tear. Moreover, custom-made mouthguards cost more than standard boil-and-bite models.

Additional Strategies for Managing Jaw Clenching

In addition to using mouthguards for jaw clenching, there are various strategies you can incorporate into your routine for improved effectiveness. These strategies address the underlying causes of jaw clenching, such as stress and anxiety.

Here are some additional techniques to consider:

  • Stress management: Since stress is a common trigger for jaw clenching, adopting stress management techniques, such as deep breathing exercises, meditation, and yoga, can be beneficial.
  • Jaw muscle relaxation exercises: Practicing jaw muscle relaxation exercises can help alleviate tension in the jaw. Simple techniques like gently massaging the jaw muscles with your fingertips, applying warm compresses to the jaw area, and performing gentle jaw stretches can help significantly.
  • Avoiding trigger foods and drinks: Did you know that certain foods and drinks, such as caffeine, alcohol, and hard or chewy foods, can exacerbate jaw clenching? Limiting or avoiding these triggers can reduce the frequency and intensity of jaw clenching.
  • Cognitive-Behavioral Therapy (CBT): CBT is a form of therapy in that a qualified therapist can guide you in identifying and modifying thought patterns and behaviors. It can help manage jaw clenching by addressing underlying psychological factors.

It is important to note that while mouthguards can help alleviate jaw clenching symptoms, they do not treat the condition. It is essential to consult with a healthcare professional for an accurate diagnosis and a treatment plan that works on the root factors causing the problem.
