Teeth Grinding: Causes, Symptoms, and Treatments

Teeth grinding, also known as bruxism, is a condition where the individual unconsciously grinds, clenches, or gnashes their teeth. This condition can happen during the day or, more commonly, during sleep. It can cause problems such as tooth damage, headaches, and jaw pain. This article will examine bruxism’s causes, symptoms, and treatments.

Causes of Teeth Grinding

There are several theories as to what causes teeth grinding. One of the most widely accepted theories is that bruxism is the body’s response to stress or anxiety. Other potential causes include:

  • Abnormal bite
  • Missing or crooked teeth
  • Sleep disorders
  • Medications
  • Substance abuse (e.g., caffeine, tobacco, alcohol)

While the exact cause of bruxism varies from person to person, it is clear that it can cause significant damage to both the teeth and the jaw joint.

Symptoms of Teeth Grinding

Teeth grinding can cause several noticeable symptoms, such as:

  • A headache or earache
  • Sensitive teeth
  • A sore jaw or facial muscles
  • Chipped, cracked, or loose teeth
  • Difficulty sleeping

If you experience these symptoms, it’s important to talk to a dentist or doctor immediately.

Treatments for Teeth Grinding

The treatment will depend on the severity of your condition. For those with mild bruxism, the dentist may recommend wearing a mouthguard at night to protect the teeth. The mouthguard may also help to reduce any discomfort or headaches that may come with it.

The dentist may recommend more extensive treatment for those with more severe bruxism. This may include:

  • Correcting any dental issues, such as misaligned teeth or a bad bite.
  • Taking muscle relaxants or anti-anxiety medications.
  • Receiving botox injections.
  • Behavior modification techniques such as stress reduction or relaxation techniques.

Sometimes, a combination of treatments may be necessary to manage bruxism effectively.


Teeth grinding can cause significant damage to your teeth and jaw. If you experience any symptoms of bruxism, it’s important to talk to a dentist or doctor who can provide an accurate diagnosis and recommend the right course of treatment. Getting prompt attention for this condition can protect your teeth and ensure oral health.
