What Is Bruxism?

Bruxism is the medical term for teeth grinding or clenching, which often occurs during sleep. If you wake up with sore jaw muscles or notice that your teeth are becoming worn down, you may be experiencing bruxism. This condition can be a result of stress, anxiety, misaligned teeth, or certain medications. 

Teeth grinding can have several negative effects on your oral health. It can lead to tooth sensitivity, tooth fractures, and even tooth loss if left untreated. Additionally, bruxism can cause headaches, earaches, and facial pain. It's important to address this issue to prevent further damage to your teeth and overall well-being.1

What Are The Main Causes Of Bruxism?

The exact causes of bruxism can vary from person to person, and it is often a combination of factors that contribute to the condition. Here are some of the main causes of bruxism:

Stress and Anxiety

Emotional stress and anxiety are common triggers for teeth grinding. The subconscious act of clenching or grinding the teeth during times of heightened stress can provide a temporary relief of tension, leading to a habit that persists even when the stressor is gone.2

Misaligned Teeth

Malocclusion, or misaligned teeth, can contribute to bruxism. When teeth do not fit together properly, it can cause an imbalance in the jaw muscles, leading to grinding or clenching as the body tries to find an optimal position for the bite.

Sleep Disorders

Bruxism has been associated with certain sleep disorders, such as sleep apnea and snoring. The interruption in normal sleep patterns can lead to teeth grinding as a way for the body to open the airway or breathe more effectively.

Medications And Substances

Some medications, such as certain antidepressants or other psychiatric medications, have been linked to bruxism as a side effect. Additionally, the use of substances like caffeine, tobacco, or alcohol can increase the likelihood of teeth grinding.

Age And Genetics

Bruxism can occur at any age, but it is more common in certain age groups, such as children and young adults. There may also be a genetic component to bruxism, with a family history of the condition increasing the likelihood of developing it.

What Are The Symptoms Of Bruxism?

If you suspect you may have bruxism, it's important to be aware of the common symptoms associated with this condition. Here are some signs that may indicate the presence of teeth grinding:

  • Grinding Or Clenching Noises: If you sleep with a partner, they may notice grinding or clenching noises coming from your mouth during the night.
  • Worn Enamel: Over time, the consistent grinding and clenching of teeth can lead to worn-down enamel. Your dentist may notice signs of enamel erosion during a routine dental examination.
  • Tooth Sensitivity: Exposed dentin resulting from worn enamel can cause tooth sensitivity to hot or cold foods and beverages.
  • Jaw Pain Or Soreness: Bruxism can cause pain and soreness in the jaw joint or muscles, especially upon waking up in the morning.
  • Headaches: Teeth grinding can lead to frequent headaches, especially in the temples or the area surrounding the temples.
  • Facial Pain: The excessive muscle activity associated with bruxism can result in facial pain or discomfort. This can manifest as pain in the cheeks, ears, or even around the eyes.
  • Tight Or Tired Jaw Muscles: If you notice your jaw muscles feeling tight, fatigued, or achy, it may be a sign of bruxism.
  • Indentations On The Tongue: Persistent grinding and clenching of teeth can cause indentations or impressions on the sides of the tongue.

What Are The Treatments For Teeth Grinding?

Treating bruxism, or teeth grinding, involves a variety of approaches depending on the severity and underlying causes. Here’s a comprehensive look at the common treatments for bruxism:

Dental Guards or Splints

These are often the first line of treatment. Custom-made by dentists, these mouth guards or splints are worn at night to protect the teeth from grinding and clenching. They help distribute the pressure, prevent tooth wear, and reduce jaw strain.

Stress Management and Relaxation Techniques

Since stress is a major contributor to bruxism, techniques such as meditation, yoga, and deep breathing can be beneficial. Professional counseling or stress management courses may also be recommended.

Physical Therapy

This involves exercises to improve jaw movement and relieve tightness in the muscles. Physical therapists can also teach techniques to relax the jaw.


In some cases, medications may be prescribed. These can include muscle relaxants before bedtime for a short period, or in certain instances, antidepressants or anti-anxiety medications if bruxism is related to anxiety or depression.

Dental Correction

If bruxism has led to significant tooth damage or if misaligned teeth are contributing to the problem, dental procedures like reshaping the chewing surfaces of your teeth or orthodontic treatment may be necessary.

Behavioral Therapies and Habit Reversal Techniques

Cognitive behavioral therapy (CBT) can be effective in changing the behaviors associated with bruxism. Habit-reversal techniques and learning proper mouth and jaw position can also be helpful.

Lifestyle Changes

Reducing caffeine and alcohol intake, which can aggravate bruxism, is often advised. Additionally, becoming more conscious of clenching and consciously relaxing the jaw throughout the day can help.

Jaw Exercises

Gentle stretching and massage can help to relieve muscle tightness and pain. A dentist or physical therapist can provide specific exercises.

Botox Injections

In some severe cases where traditional treatments don’t provide relief, Botox injections into the jaw muscles have been used as an alternative treatment.

What Are The Benefits Of A Teeth Grinding Treatment?

Seeking treatment for bruxism can provide several benefits for your overall oral health and well-being. Here are some of the key advantages of addressing bruxism:

Protecting Tooth Structure

By managing bruxism, you can prevent further damage to your teeth. Treating the condition can help preserve the integrity of your tooth structure, preventing enamel erosion, fractures, and other dental issues that can result from teeth grinding.3


Protecting Tooth Structure


Alleviating Discomfort

Bruxism can cause jaw pain, headaches, and facial discomfort. Treating the underlying condition can help alleviate these symptoms, improving your overall quality of life. By reducing muscle tension and relaxing the jaw, you can experience relief from the discomfort caused by teeth grinding.

Preventing Tooth Sensitivity

Excessive grinding can lead to tooth sensitivity, as the protective enamel wears away, exposing the sensitive dentin layer. By managing bruxism, you can prevent or minimize tooth sensitivity, allowing you to enjoy hot or cold foods and beverages without discomfort.

Preserving Dental Restorations

If you have dental restorations such as fillings, crowns, or veneers, bruxism can increase the risk of damage to these restorations. Treating bruxism can help protect your investment in dental work, prolonging the lifespan of your restorations and reducing the need for potential repairs or replacements.

Improving Sleep Quality

Bruxism is often associated with sleep disturbances and disorders. By addressing the underlying cause of teeth grinding, such as stress or misaligned teeth, you can improve your sleep quality. Better sleep can lead to increased energy levels, improved mood, and enhanced overall well-being.

How Can Bruxism Be Diagnosed?

If you suspect that you may be grinding your teeth, it's important to consult with a dental professional for a proper diagnosis. A dentist or dental hygienist will be able to assess your oral health and determine if you have bruxism. Here are some common methods used to diagnose bruxism:

  • Clinical Examination: During a dental examination, your dentist will carefully examine your teeth, checking for any signs of wear or damage that may indicate teeth grinding. They will also evaluate the alignment of your teeth and jaw, looking for any occlusal or bite issues that may contribute to bruxism.
  • Patient History: Your dentist will ask you about your symptoms and any related factors, such as stress levels, medications, or sleep disturbances. Providing thorough information about your dental habits and lifestyle can help your dentist make an accurate diagnosis.
  • Dental X-Rays: In some cases, your dentist may require dental X-rays to evaluate the extent of any tooth damage and assess the health of the underlying structures, such as the jawbone and temporomandibular joint.
  • Sleep Study: If your dentist suspects that your bruxism is related to a sleep disorder, they may recommend a sleep study or refer you to a sleep specialist. A sleep study can monitor your sleep patterns and help identify any underlying sleep disturbances that may contribute to teeth grinding.

How Does Teeth Grinding Affect Dental Health?

Bruxism can have a significant impact on your dental health. The constant grinding and clenching of teeth can lead to various dental problems, including:

Worn Enamel

The force exerted during teeth grinding can wear down the protective enamel layer of your teeth. As enamel wears away, the underlying dentin becomes more exposed, increasing the risk of tooth sensitivity, cavities, and other dental issues.

Tooth Fractures

Frequent grinding and clenching can put excessive pressure on your teeth, increasing the likelihood of fractures or cracks. These fractures can range from minor chips to more severe damage, potentially requiring dental restorations like fillings or crowns.

Gum Recession

The constant pressure from grinding can lead to gum recession, where the gum tissue pulls away from the teeth. Receding gums expose more of the tooth's surface, making it susceptible to decay and sensitivity.

Temporomandibular Joint (TMJ) Disorders

Bruxism can strain the jaw joint, leading to TMJ disorders. Symptoms may include jaw pain, clicking or popping sounds, difficulty opening or closing the mouth, and even lockjaw. Managing bruxism can help alleviate TMJ-related discomfort.

Headaches And Facial Pain

The excessive muscle activity associated with teeth grinding can lead to headaches, earaches, and facial pain. This discomfort can extend to the head and neck muscles, causing tension and discomfort throughout the day.

Final Thoughts

Bruxism is more than just teeth grinding; it's a condition that requires attention and care to ensure the overall health of your teeth and the effectiveness of your dental treatments, including at-home teeth whitening. With the right knowledge and tools, you can manage bruxism and maintain that bright, confident smile. Remember, a white smile isn't just about aesthetics—it's also a sign of strong dental health.
