How TMJ Affects Oral Health and How to Manage It

How TMJ Affects Oral Health and How to Manage It

The temporomandibular joint plays a crucial role in our daily lives by facilitating actions such as talking, chewing, and even yawning. However, many individuals are unaware of temporomandibular joint dysfunction (TMJ) disorder and its impact on oral health. 

This article will explore TMJ disorders, their effects on oral health, and various TMJ treatment options and preventive measures to manage and mitigate TMJ-related issues.

Understanding TMJ Disorders

The temporomandibular joint, often referred to as TMJ, is the hinge that connects your jaw to your skull. It allows you to move your jaw in various directions, enabling speaking, chewing, and swallowing activities. A TMJ disorder can affect the jaw joint and the muscles that control its movement.

Common symptoms of TMJ disorders include pain and discomfort in the jaw area, difficulty opening and closing the mouth, clicking or popping sounds during jaw movements, and even headaches or earaches. These symptoms can significantly impact your oral health in the following ways:

Tooth Wear

When your jaw is misaligned, it can result in uneven pressure on your teeth during activities like chewing. Over time, this imbalance can cause excessive tooth wear and damage, compromising oral health. Addressing the misalignment is crucial to preventing these issues and maintaining healthy teeth.

Gum Problems

TMJ disorders often lead to irregularities in your bite, affecting how your upper and lower teeth come together. This misalignment can contribute to gum issues and tooth mobility, increasing the risk of problems like gum disease and tooth instability, emphasizing the importance of managing TMJ disorders for oral health.


TMJ disorders often contribute to bruxism, where individuals involuntarily grind or clench their teeth, particularly during sleep. This habit can result in tooth damage, including chipping and excessive wear, and is a common source of jaw pain and discomfort for those with TMJ issues.

Difficulty Chewing and Swallowing

The pain and discomfort linked with TMJ disorders can hinder the normal chewing and swallowing process, which may lead to avoiding certain foods or opting for softer options. In turn, it impacts nutrition and dietary choices, potentially causing deficiencies or imbalances in one’s diet.

Speech Impairment

TMJ disorders may disrupt speech by altering jaw and tongue positioning. These changes can make it challenging to articulate specific words and sounds clearly, affecting one’s communication ability.

What Causes TMJ

Several factors cause TMJ disorders, such as physical trauma to the jaw or related muscles (e.g., a strong impact or whiplash). Other causes include:

  • Teeth grinding and clenching that puts much pressure on the joint
  • Arthritis
  • Movement of the soft disc between the joint’s ball and socket
  • Muscle tension due to stress

Treatments for TMJ

Thankfully, various treatments are available to manage TMJ disorders, from home management techniques to medical interventions. The choice of treatment will depend on the severity of your condition and its underlying causes. Here are some common practices on how to treat TMJ:

Home Management

For mild cases of TMJ disorders, you can start with self-care measures like applying ice packs, gentle jaw exercises, and avoiding hard, chewy foods.

Physical Therapy

A physical therapist can treat TMJ with exercises and techniques to improve jaw mobility and reduce pain.

Complementary and Alternative Medicine

Relieve TMJ-related pain with alternative therapy

Some individuals find relief through complementary therapies like acupuncture, massage, or chiropractic adjustments.

Behavioural Therapy

Cognitive-behavioural therapy (CBT) can be beneficial for managing the stress and anxiety often associated with TMJ disorders, which can exacerbate symptoms.


Healthcare professionals may prescribe pain relievers, muscle relaxants, and anti-inflammatory drugs to manage the pain and inflammation linked to TMJ disorders. These can help reduce discomfort and improve jaw joint function, relieving individuals with TMJ-related issues.

Intraoral Appliances

Dentists can provide customized oral appliances, such as splints or night guards, to reduce clenching and grinding of teeth and jaw clicking, relieving pressure on the jaw joint.

Orthodontic Treatment

In cases where misaligned teeth or bite issues contribute to TMJ disorders, orthodontic treatments like braces or aligners may be recommended.


In some situations, injections of Botox or corticosteroids into the jaw muscles can temporarily relieve TMJ pain and discomfort.


Surgical intervention typically serves as a last resort when other treatments prove ineffective. Procedures can range from arthrocentesis, which involves flushing out the joint, to open-joint surgery for more severe cases.

Tips for Preventing TMJ Disorders

Prevention is always better than cure. While some factors leading to TMJ disorders may not be avoidable, staying away from things that make TMJ worse and adopting healthy habits can help reduce your risk and mitigate the severity of symptoms. Here are some practical tips for preventing TMJ disorders:

Practice Good Oral Hygiene

Practice regular brushing, flossing, and dental check-ups

Regular brushing, flossing, and dental check-ups can help maintain oral health and reduce the risk of issues that may lead to TMJ disorders.

Avoid Hard or Chewy Foods

Consuming hard-to-chew foods, such as tough meats or hard candies, can place undue stress on the jaw joint. Opting for softer food options minimizes the strain on the TMJ, reducing the risk of discomfort and potential worsening of TMJ issues.

Take Breaks While Chewing

Don’t rush through meals. Take time to chew your food slowly and thoroughly, reducing the strain on your jaw.

Practice Good Posture

Practicing good posture is essential for reducing muscle tension in the neck and shoulders, which can influence TMJ health. Maintaining proper alignment reduces the risk of stress on the jaw joint, thus lowering the likelihood of developing TMJ disorders and associated symptoms.

Use a Mouthguard

If you grind your teeth at night, a custom-made mouth guard can protect your teeth and jaw from bruxism.

Manage Stress

Stress is a significant contributor to TMJ disorders. Use stress-reduction techniques such as yoga, meditation, or deep breathing exercises.

Treat Misaligned Teeth or Bite Issues

If you notice irregularities in your bite or the alignment of your teeth, consult a dentist or orthodontist to address these issues before they lead to TMJ problems.

TMJ disorders can significantly impact oral health, causing pain, discomfort, and other related problems. It’s essential to be aware of TMJ disorders’ symptoms and effects and seek treatment when necessary. The broad array of treatment choices, spanning self-care practices to medical interventions, provides optimism for individuals enduring TMJ disorders. Moreover, fostering good oral hygiene, embracing healthful dietary practices, and effectively coping with stress can be instrumental in preventing the development of these conditions in the first place.
