What Is Teeth Grinding (Bruxism)?

Teeth grinding, also known as bruxism, often occurs unconsciously—especially during sleep. If you frequently wake up with jaw pain, headaches, or facial discomfort, it may be a sign that you grind your teeth at night.

Over time, bruxism can lead to:

• Tooth sensitivity and pain
• Worn-down or fractured teeth
• Loose teeth
• Damage to gums and supporting bone
• Temporomandibular joint (TMJ) disorders

How Do You Know If You Grind Your Teeth?

Many people are unaware of the habit until:

• A partner notices grinding sounds during sleep
• A dentist identifies signs of tooth wear or enamel damage

Common Signs and Symptoms

• Jaw pain or tightness
• Morning headaches
• Facial or neck pain
• Tooth wear or chipping
• Increased tooth sensitivity

A dentist can evaluate these symptoms and confirm whether bruxism is the underlying cause.

How Is Teeth Grinding Treated?

Treatment depends on the underlying cause and severity of the condition. Your dentist will perform a thorough examination and discuss possible contributing factors.

Common Treatment Options

• Night Guard (Occlusal Splint): A custom-made appliance worn during sleep to protect teeth from grinding forces. While effective in preventing damage, it does not eliminate the habit itself.
• Stress Management: Stress is one of the most common triggers of bruxism. Techniques such as relaxation exercises, reading, music, or warm baths can help reduce muscle tension. Applying a warm compress to the jaw may also relieve discomfort.
• Bite Adjustment and Dental Correction: If uneven bite or misalignment is contributing to grinding, treatments such as:
  • Tooth reshaping
  • Restorations (fillings, crowns)
  • Orthodontic treatment (including clear aligners) may be recommended to restore proper function

Key Takeaway

Teeth grinding is more than just a habit—it can gradually damage your teeth and affect your overall oral health. Early diagnosis and proper management can:

• Prevent long-term damage
• Relieve pain and discomfort
• Protect your smile

Expert Insight by Dr. Pitchaya Vadhanakrai

Untreated bruxism places continuous force on the teeth, leading to worn, shortened, or fractured teeth and frequent failure of fillings. Prevention is key—wearing a custom night guard and avoiding hard foods can help protect long-term oral health.
