Why Wear a Mouthguard at Night

why wear a mouthguard at night

Wearing a mouthguard at night can provide numerous benefits for your oral health and overall well-being. Whether you grind your teeth or suffer from sleep apnea, a mouthguard can help alleviate these issues and protect your teeth. In this article, we will explore the various reasons why wearing a mouthguard at night is essential.

Prevents Teeth Grinding

Teeth grinding, also known as bruxism, is a common problem that can lead to tooth damage, jaw pain, and headaches. Wearing a mouthguard at night creates a protective barrier between your upper and lower teeth, preventing them from grinding against each other. This can help reduce the risk of tooth fractures, enamel wear, and jaw joint problems.

Additionally, a mouthguard can help relax the jaw muscles, reducing tension and discomfort associated with teeth grinding. It can also help alleviate the symptoms of temporomandibular joint disorder (TMJ), a condition often caused by bruxism.

Reduces the Risk of Jaw Disorders

Wearing a mouthguard can significantly reduce the risk of developing jaw disorders, such as TMJ. By providing a cushioning effect, the mouthguard absorbs the impact of teeth grinding and clenching, minimizing the strain on the jaw joint. This can help prevent joint inflammation, pain, and limited jaw movement.

Alleviates Sleep Apnea Symptoms

For individuals with sleep apnea, a mouthguard can be a game-changer. Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep. A specially designed mouthguard, known as a mandibular advancement device (MAD), can help keep the airway open by repositioning the jaw and tongue. This allows for improved airflow and reduces the frequency and severity of sleep apnea episodes.

Protects Against Sports Injuries

A mouthguard is not only beneficial for nighttime use but also for sports activities. Engaging in contact sports without proper mouth protection can result in dental injuries, such as chipped or knocked-out teeth. Wearing a mouthguard during sports can help cushion the impact and protect your teeth, lips, and tongue from injury.

Prevents Snoring

Snoring can disrupt your sleep and that of your partner. A mouthguard designed to address snoring can help open the airway and reduce the vibration of soft tissues in the throat, which is often the cause of snoring. By keeping the airway unobstructed, a mouthguard can promote better airflow and minimize snoring.

Improves Sleep Quality

Wearing a mouthguard can improve your overall sleep quality. By reducing teeth grinding, snoring, and sleep apnea episodes, a mouthguard can help you achieve a more restful and uninterrupted sleep. Better sleep quality leads to improved energy levels, concentration, and overall well-being.

Preserves Dental Work

If you have dental restorations such as crowns, bridges, or veneers, wearing a mouthguard can help protect them. Teeth grinding can put excessive pressure on these dental prosthetics, leading to their damage or premature failure. A mouthguard acts as a barrier, preventing direct contact between the teeth and the restorations, thus preserving their longevity.


Wearing a mouthguard at night offers numerous benefits for your oral health and overall sleep quality. It can prevent teeth grinding, reduce the risk of jaw disorders, alleviate sleep apnea symptoms, protect against sports injuries, prevent snoring, improve sleep quality, and preserve dental work. If you experience any of these issues, consult with your dentist to determine the most suitable mouthguard for your needs and enjoy the benefits of a restful night’s sleep.
