What is Bruxism?

Bruxism is defined as the habit of clenching, grinding, and gnashing the teeth, typically during sleep. People who grind their teeth are referred to as “bruxers,” and most don’t realize they have the disorder.

“About half of adults in the U.S. grind their teeth. Although, only 20 percent of them are considered ‘bruxers,’ which means they grind their teeth enough to destroy tooth enamel.”’

Men and women over 25 years of age grind their teeth more often than children. Since a child’s jaw and teeth grow quickly, teeth grinding typically isn’t a damaging habit. This is because children who develop minor bruxism usually outgrow it before pain and damage occur. For adults, the problem can be more severe and typically requires treatment.

Untreated bruxism can lead to:


Doctors and dentists are not quite sure what causes bruxism. Although, teeth grinding may be related to psychological, physical, and hereditary factors such as stress, respiratory infections, allergies, earaches, and certain medications.

Teeth grinding typically occurs while sleeping. Although, people can also do so while they are awake. There are two types of bruxism, including:

  1. Sleep Bruxism teeth grinding and clenching associated with arousals during sleep.
  2. Awake Bruxism teeth grinding and clenching associated with stress, anxiety, anger, or tension.

Risk Factors

Some people are more prone to developing bruxism than others. The most common factors that increase the risk of teeth grinding include:

Anxiety and Stress — high stress or anxiety levels can lead to increased teeth grinding when awake.

Medications — certain medications, such as antidepressants, can increase teeth grinding.

Alcohol — drinking alcohol excessively doubles a person’s chance of developing bruxism.

Smoking — smokers are twice as likely to develop bruxism since nicotine releases dopamine.

Caffeinated Beverages — excessive caffeine consumption speeds up the heart rate and releases dopamine, which may be linked to excessive teeth grinding.

Drugsstimulants, such as cocaine, ecstasy, and amphetamines, can cause severe awake and sleep bruxism.

Hereditary — sleep bruxism tends to occur in families.

Disorders — dementia, Parkinson’s disease, night terrors, sleep apnea, and attention-deficit/hyperactivity disorder (ADHD) are commonly linked to bruxism.

Age — bruxism becomes more common as people age. Some children may develop the condition, but it is less common than adults.

Common Symptoms

Common indicators of bruxism include:

  • Teeth grinding and clenching.
  • Frequent headaches that start in the temples.
  • Frequent earaches.
  • Lockjaw, which is when the mouth cannot open or close completely.
  • Clicking or popping sounds in the jaw when chewing.
  • Loss of tooth enamel due to excessive grinding.
  • Flattened or worn out teeth.
  • Damage to dental fillings.
  • Fractured, loose, or chipped teeth.
  • Tooth sensitivity and pain due to worn down enamel.
  • Soreness in the jaw, face, and neck.
  • Damage on the inside of the cheeks due to chewing them.
  • Tongue indentations.

Treatment Options for Bruxism

Treatment may include:

Mouthguards and Splints

Mouthguards and splints are both considered occlusal appliances because they help with teeth positioning and jaw alignment, especially while sleeping. They are made of hard acrylic because heavy bruxers will grind right through soft ones. The devices are also custom-made for every patient and are used to protect teeth from grinding, clenching, and gnashing. In addition, mouthguards also relieve jaw pain and discomfort.

Dental Corrections

Receiving regular dental exams (at least twice a year) can help catch damage caused by bruxism. If a patient’s teeth are cracked, missing, or misaligned, restorative treatment is necessary. For example, dentures or dental crowns may be recommended by a dentist depending on the severity of bruxism damage.


Medications are a very effective treatment option for bruxism. For example, common medications include muscle relaxants, botox injections, anti-anxiety medications, or antidepressants.

Stress and Anxiety Treatment

If the cause of bruxism is from stress, anxiety, or other psychological conditions, a doctor may recommend cognitive behavioral therapy (CBT). Behavior therapy and/or biofeedback treatment may also be necessary.
