The Mystery Behind Bruxism and TMD

Do you wake up with a sore jaw or experiencing clicking sounds when you chew? You might be dealing with two common yet perplexing oral health issues: bruxism and temporomandibular joint disorders (TMD). Bruxism, often called teeth grinding or clenching, is a habit that affects people of all ages. At the same time, Temporomandibular joint disorders (TMD) affect the temporomandibular joint, which connects your jaw to your skull. TMD can cause pain and dysfunction in the jaw joint and surrounding muscles, leading to jaw pain, clicking or popping sounds when chewing, difficulty opening or closing the mouth, and headaches. TMD can result from various factors, including teeth grinding (bruxism), jaw injuries, arthritis, and stress.

But are these two conditions linked? Let’s dive into the research to uncover the truth.

What Does the Science Say?

Recent studies have sought to unravel the connection between bruxism and TMD, shedding light on how these seemingly unrelated issues might be intertwined. A systematic review and analysis published in the journal Evidence-Based Dentistry explored the available evidence, examining data from numerous studies to determine if there’s a significant relationship between bruxism and TMD.

What Did the Study Reveal?

After combing through a plethora of research articles, the analysis identified a compelling link between bruxism and TMD. The results showed that individuals with bruxism were significantly more likely to develop TMD compared to those without the habit. The presence of bruxism increased the odds of experiencing TMD symptoms by more than double.

How Does Bruxism Contribute to TMD?

But why does bruxism seem to pave the way for TMD? While the exact mechanisms remain a topic of ongoing research, experts suggest that repetitive teeth grinding and clenching may place undue stress on the temporomandibular joint and surrounding structures. Over time, this strain could lead to inflammation, muscle tension, and other issues characteristic of TMD.

Practical Implications: What Does This Mean for You?

If you’re someone who grinds their teeth or experiences jaw pain, this research might offer valuable insights into your oral health. Recognizing the connection between bruxism and TMD can empower you to take proactive steps to protect your smile and alleviate discomfort. From practicing stress-reduction techniques to seeking professional guidance from a dentist, there are various strategies you can explore to manage bruxism and minimize its impact on your jaw joint.

How Is Bruxism Treated?

Bruxism can be treated through various approaches, depending on the underlying cause and severity of the condition. Here are some standard treatment options:

  1. Mouthguards or Night Guards: These custom-fitted dental appliances are worn over the teeth during sleep to protect them from grinding and clenching.
  2. Stress Management: Since stress and anxiety can exacerbate bruxism, stress-reduction techniques such as relaxation exercises, counseling, or mindfulness meditation may be helpful.
  3. Dental Correction: In some cases, dental issues such as misaligned teeth or bite problems can contribute to bruxism. Dental treatments like orthodontics or dental restorations may be recommended to address these issues.
  4. Medications: Muscle relaxants or anti-anxiety medications prescribed by a healthcare professional may help relax the jaw muscles and alleviate grinding.
  5. Behavioral Therapy: Cognitive-behavioral therapy (CBT) or biofeedback therapy can effectively identify and modify the behaviors associated with bruxism.
  6. Lifestyle Changes: Avoiding stimulating substances like caffeine and alcohol, practicing good sleep hygiene, and implementing relaxation techniques before bedtime can help reduce bruxism episodes.

It’s essential to consult with Dr. Marielaina Perrone or healthcare provider to determine the most appropriate treatment plan based on individual needs and circumstances.


In the realm of oral health, the relationship between bruxism and TMD continues to intrigue researchers and clinicians alike. While we’ve made significant strides in understanding this connection, there’s still much to learn about how these conditions intersect and influence one another. By staying informed and proactive about your oral health, you can confidently navigate the complexities of bruxism and TMD, ensuring a brighter, more comfortable smile for years to come.
