睡覺時有磨牙!?拆解磨牙的原因、影響和改善方法。

 Many people unconsciously clench their teeth and grind them while sleeping, causing significant distress. This not only affects those nearby but can also lead to tooth damage and pain in facial muscles or the jaw. So why do people grind their teeth at night? What are the effects? Are there any solutions?

Why do people grind their teeth while sleeping?

The medical community has not yet fully pinpointed the exact causes of bruxism, but several common factors can trigger it, including psychological issues, physical conditions, and lifestyle habits.

  1. Psychological Issues: Bruxism is often related to stress and anxiety. When individuals face stress in their daily lives, they may unconsciously grind their teeth during sleep as a way to release emotions. Studies have shown that people with higher levels of psychological stress are more prone to grinding their teeth.
  2. Sleep Apnea: Grinding teeth during sleep can actually be a transitional phase from deep sleep to light sleep. Research indicates that bruxism may serve as a self-protective behavior; when breathing becomes difficult or stops during sleep, the brain sends signals to grind the teeth, thereby opening the airways and restoring breathing.
  3. Medication Effects: Certain medications, such as selective serotonin reuptake inhibitors used for depression, may also have side effects that lead to teeth grinding at night.
  4. Dental Issues in Children: Children can also experience bruxism. During their teething phase, issues like misaligned teeth or improper bites can increase the likelihood of grinding.

What effects does teeth grinding have?

  1. Tooth Damage: Long-term grinding can wear down the enamel on the teeth, exposing the underlying dentin and pulp. This can lead to sensitivity or pain when consuming hot or cold foods and beverages. If the grinding is severe, the teeth may become increasingly fragile and more likely to fracture. Additionally, prolonged grinding can damage the surrounding structures that support the teeth, such as the alveolar bone, ultimately leading to tooth looseness.
  2. Temporomandibular Joint (TMJ) Issues: Continuous grinding may result in overuse of the chewing muscles and those near the TMJ, causing cartilage damage and muscle fatigue, which can lead to jaw pain and clicking sounds when opening the mouth.

How to improve bruxism?

To address bruxism, it’s essential to first understand its causes and then target them accordingly. If grinding is related to emotional stress, finding suitable stress relief methods and maintaining a positive mindset is crucial. If the cause is sleep apnea, seeking treatment from a relevant physician is necessary.

Understanding the root causes of bruxism is undoubtedly the most important step in treatment. However, regardless of the cause, it’s advisable to wear a mouthguard during sleep, which can effectively reduce the damage caused by grinding. This mouthguard should be assessed and custom-made by a dentist based on the patient’s specific dental condition. Therefore, if you have a grinding habit, it’s essential not only to treat the underlying causes but also to consult a dentist for advice and possibly get a custom-made mouthguard.
