Teeth Grinding and TMJ: More Related Than You Thought

Bruxism, more commonly known as teeth grinding, affects millions of people. One of the most significant negative outcomes of bruxism is temporomandibular joint disorders (TMD), which can result in significant pain and discomfort.

What Is Bruxism?

Bruxism is the medical term for teeth grinding or clenching. It occurs during sleep or while awake (awake bruxism) and can be caused by a range of factors, including stress, anxiety, and sleep disorders. When bruxism goes untreated, it can lead to a range of dental problems, including:

  • Tooth wear
  • Cracks
  • Fractures
  • Gum Disease
  • Jaw Pain
  • Headaches

Symptoms of Bruxism

Symptoms you may experience if you’re suffering from bruxism include:

  • Teeth Grinding or Clenching: One of the most obvious signs of bruxism is grinding or clenching the teeth, which creates a grinding or clicking sound that others can hear.
  • Worn, Damaged, or Sensitive Teeth: Over time, bruxism can wear down the teeth and cause them to become chipped or cracked. Teeth can also become sensitive to hot and cold temperatures.
  • Headaches: Bruxism can cause tension headaches, especially in the temples.
  • Jaw Pain: Constant grinding or clenching of the teeth can cause pain and soreness in the jaw joints, which can radiate to the ears.
  • Earaches: Bruxism can cause earaches, as the constant pressure on the jaw joint can lead to inflammation and ear pain.
  • Facial Pain: Bruxism can cause pain in the face, especially in the cheeks and around the eyes.
  • Sleep Disruption: Bruxism can cause sleep disruptions, as the grinding or clenching of the teeth can wake the person up or disrupt their sleep cycle.

If you’re experiencing any of these symptoms, schedule an appointment with Dr. Goel for an evaluation. We'll help diagnose the cause of your symptoms and recommend the best treatment.

How Bruxism Can Lead to TMJ Disorders

There’s a strong link between bruxism and TMJ disorders. When bruxism occurs frequently and with significant force, it can have several effects on the TMJ, which may ultimately lead to TMJ disorders.

In severe cases, you may develop TMJ disorder from teeth grinding due to:

  • Excessive Pressure: Bruxism often involves forceful grinding and clenching of teeth, which can exert excessive pressure on the temporomandibular joints. Over time, this continuous stress can cause wear and tear on the joint.
  • Muscle Fatigue: The muscles used in bruxism, particularly the masseter and temporalis muscles, can become tired from the constant grinding and clenching. This muscle fatigue can affect the stability and functioning of the TMJ.
  • Inflammation: Repetitive grinding and clenching can lead to inflammation in the TMJ area. Inflammation can cause pain, swelling, and discomfort, making it difficult to open and close the mouth comfortably.
  • Joint Misalignment: Prolonged bruxism can lead to the misalignment of the TMJ. When the joint doesn't function properly, it can result in a range of TMJ disorders.
  • Damage to Teeth: Bruxism can cause significant damage to the teeth, including chipping, cracking, and excessive wear. This dental damage can alter the way the upper and lower teeth come together (occlusion), which can further contribute to TMJ problems.
  • Limited Jaw Movement: As the TMJ deteriorates due to the effects of bruxism, it may result in limited jaw movement. This can lead to difficulty in chewing, speaking, and even breathing in severe cases.

Prevention of Bruxism and TMJ Disorders

Preventing and treating bruxism can help reduce the risk of developing a TMJ disorder. To avoid bruxism and TMJ, make sure to do the following:

  • Wearing a Mouth guard: A mouth guard can help protect teeth from grinding and clenching during sleep.
  • Managing Stress and Anxiety: Stress and anxiety are common triggers for bruxism, so finding ways to manage these emotions can help reduce the possibility of teeth grinding.
  • Getting Enough Sleep: Fatigue and sleep disorders can increase the risk of bruxism, so getting enough rest is important.
  • Avoiding Caffeine and Alcohol: These substances can increase muscle tension and exacerbate bruxism.
  • Practicing Good Dental Hygiene: Regular brushing, flossing, and dental checkups can help prevent dental problems that can lead to bruxism.

Treatment of Bruxism and TMJ Disorders

Treatment for TMD and bruxism varies depending on the cause and severity of your condition. Treatment options may include:

  • Mouth Guards or Splints: A dental mouth guard or splint can be worn at night to protect the teeth from damage caused by grinding or clenching. These can be custom-fitted by a dentist to ensure maximum protection.
  • Stress Management: Since stress and anxiety are common causes of bruxism, stress management techniques such as relaxation exercises, meditation, and counseling can help reduce the frequency and severity of teeth grinding.
  • Lifestyle Changes: Avoiding alcohol and caffeine, as well as establishing a regular sleep pattern, can help reduce the occurrence of bruxism.
  • Medications: Muscle relaxants and anti-anxiety medications may be prescribed to alleviate symptoms of bruxism.
  • Dental Work: If damage has already been done to the teeth, dental work such as bonding, crowns, or bridges may be necessary to restore the teeth to their original shape and size.
  • Behavioral Therapy: In severe cases, Dr. Goel may recommend behavioral therapy to help break the habit of teeth grinding.

Frequently Asked Questions

Are TMJ and bruxism the same?

No, TMJ (temporomandibular joint) disorders and bruxism (teeth grinding) are not the same, but there’s a link between the two. Bruxism is a habit of grinding, clenching, or gnashing the teeth, while TMJ disorders are conditions that affect the jaw joint and muscles that control jaw movement.

What does bruxism look like?

Bruxism can present differently in each individual, but some common signs of bruxism include worn, damaged, or sensitive teeth, headaches, jaw pain, earaches, facial pain, and sleep disruption. Teeth grinding or clenching can also create a grinding or loud clicking sound that others can hear

Can bruxism be cured?

Unfortunately, there’s no definitive cure for bruxism, but there are several treatment options that can help manage the condition. These include wearing a mouth guard or splint, stress management techniques, lifestyle changes, medication, dental work, and behavioral therapy. Visit a dentist to learn more about managing your bruxism.

Can bruxism cause permanent damage?

Additionally, bruxism can cause pain and damage to the jaw joint and muscles, which can lead to long-term jaw pain and dysfunction. Seek treatment for bruxism as soon as possible to prevent permanent damage.
