How Grinding Damages Your Teeth

Teeth Grinding
Published By Dr. Rachel Hall at 5 December, 2023

Teeth grinding damages your teeth in many ways and can lead to chipped, worn, cracked and fractured teeth, failing dentistry, gum issues, bone loss, TMJ pain and arthritis of the jaw joints as well as headaches, facial pain, neck issues and poor sleep quality.

Teeth Grinding aka Bruxism

Bruxism (BRUK-siz-um) is a condition in which you grind, gnash or clench your teeth. If you have bruxism, you may unconsciously clench your teeth when you’re awake (awake bruxism) or clench or grind them during sleep (sleep bruxism).

Bruxism – Teeth Clenching and Grinding

Sleep bruxism is considered a sleep-related movement disorder. People who clench or grind their teeth (brux) during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (sleep apnoea).

Mild bruxism may not require treatment. However, in some people, bruxism can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems.

Because you may have sleep bruxism and be unaware of it until complications develop, it’s important to know the signs and symptoms of bruxism and to seek regular dental care.

Signs and Symptoms of Grinding Teeth

Signs and symptoms of bruxism may include:

  • Teeth grinding or clenching, which may be loud enough to wake up your sleep partner
  • Teeth that are flattened, fractured, chipped or loose
  • Worn tooth enamel, exposing deeper layers of your tooth
  • Increased tooth pain or sensitivity
  • Tired or tight jaw muscles, or a locked jaw that won’t open or close completely
  • Jaw, neck or face pain or soreness
  • Pain that feels like an earache, though it’s actually not a problem with your ear
  • Dull headache starting in the temples
  • Damage from chewing on the inside of your cheek
  • Sleep disruption

When To See A Dentist About Bruxism

See your dentist or doctor if you have any of the symptoms listed above or have other concerns about your teeth or jaw.

What Causes Teeth Grinding and Bruxism

Doctors don’t completely understand what causes bruxism, but it may be due to a combination of physical, psychological and genetic factors.

  • Awake bruxism may be due to emotions such as anxiety, stress, anger, frustration or tension. Or it may be a coping strategy or a habit during deep concentration.
  • Sleep bruxism may be a sleep-related chewing activity associated with poor breathing and micro wake-ups called arousals during sleep.

Risk Factors For Teeth Grinding

These factors increase your risk of bruxism:

  • Stress. Increased anxiety or stress can lead to teeth grinding. So can anger and frustration.
  • Personality type. Having a personality type that’s aggressive, competitive or hyperactive can increase your risk of bruxism.
  • Medications and other substances. Bruxism may be an uncommon side effect of some psychiatric medications, such as certain antidepressants. Smoking tobacco, drinking caffeinated beverages or alcohol, or using recreational drugs may increase the risk of bruxism.
  • Family members with bruxism. Sleep bruxism tends to occur in families. If you have bruxism, other members of your family also may have bruxism or a history of it.
  • Other disorders. Bruxism can be associated with some mental health and medical disorders, such as Parkinson’s disease, dementia, gastroesophageal reflux disorder (GERD), epilepsy, night terrors, sleep-related disorders such as sleep apnoea, and attention-deficit/hyperactivity disorder (ADHD).

Teeth Grinding Damages Your Teeth

Bruxism doesn’t always cause serious complications but it can be a symptom of sleep apnoea so it should always be carefully screened.

Severe bruxism may lead to:

  • Damage to your teeth, fillings and restorations, crowns or the jaw bone that supports the teeth
  • Cracked teeth, fractured teeth and split teeth
  • Tension-type headaches
  • Severe facial or jaw pain
  • Disorders that occur in the temporomandibular joints (TMJs), located just in front of your ears, which may sound like clicking when you open and close your mouth

Treatment for Teeth Grinding

The treatments for teeth grinding include:

  • dental nightguards or appliances
  • physiotherapy
  • stress management
  • sleep studies and CPAP is sleep apnoea is present
  • muscle relaxants
  • breathing exercises and mouth taping
  • supplements including magnesium, B vitamins and vitamin D
  • bite corrections
