The Connection Between Wisdom Teeth and TMJ

The Connection Between Wisdom Teeth and TMJ

The temporomandibular joint (TMJ) is a complex hinge joint connecting the lower jaw (mandible) to the skull. It facilitates essential functions such as speaking, chewing, and swallowing. TMJ pain is a common condition that affects a significant portion of the population, causing discomfort and functional impairment. Wisdom teeth, or third molars, typically erupt during late adolescence or early adulthood and have been implicated in various dental issues. We aim to examine whether there is a link between the presence, eruption, or extraction of wisdom teeth and TMJ pain.

The relationship between wisdom teeth and TMJ issues primarily stems from the limited space in the human jaw. Here’s how they are connected:

  1. Impacted Wisdom Teeth:
    • Wisdom teeth often don’t have enough space to emerge correctly. When they do not fully erupt through the gum line, they are termed “impacted.”
    • Impacted wisdom teeth can push against neighboring teeth, causing crowding and misalignment.
    • As these teeth struggle to erupt, they may exert pressure on the TMJ, potentially leading to TMJ discomfort and pain.
  2. Malocclusion:
    • When wisdom teeth erupt improperly or cause crowding, they can affect the alignment of your bite (malocclusion).
    • Malocclusion can lead to an uneven distribution of force on the teeth, causing stress on the TMJ and leading to TMJ disorders.
  3. Inflammation and Infection:
    • Impacted wisdom teeth can create pockets where food particles and bacteria can accumulate, increasing the risk of infection and inflammation in the surrounding gum tissue.
    • Inflammation in the jaw area can exacerbate TMJ problems, leading to pain and discomfort.
  4. Muscle Tension:
    • Discomfort and pain associated with wisdom teeth can lead to increased muscle tension in the jaw, potentially contributing to TMJ disorders.

Managing Wisdom Teeth and TMJ Issues

If you suspect a connection between your wisdom teeth and TMJ discomfort, it’s crucial to consult with a dentist or oral surgeon for a thorough evaluation. Here are some management options:

  1. Removal of Wisdom Teeth:
    • If your wisdom teeth are causing issues, your dentist or oral surgeon may recommend their removal.
    • Removal can prevent further crowding, misalignment, and potential TMJ problems.
  2. TMJ Treatment:
    • Depending on the severity of your TMJ issues, various treatment options are available, including physical therapy, jaw exercises, medications, and in some cases, surgery.
  3. Regular Dental Checkups:
    • Regular dental checkups allow your dentist to monitor the development of your wisdom teeth and address any issues promptly.

Anatomy and Function of the Temporomandibular Joint

The temporomandibular joint (TMJ) is a bilateral synovial joint located in front of the ear, connecting the mandible to the temporal bone of the skull. It is a unique joint with both hinge and sliding movements, allowing for the opening, closing, and lateral movements of the jaw. The TMJ is composed of various components, including the articular disc, condyle, fossa, and ligaments. Understanding the anatomy and function of the TMJ is crucial to comprehend the potential impact of wisdom teeth on TMJ pain.

Wisdom Teeth Development and Eruption:

Wisdom teeth, also known as third molars, typically develop during adolescence and may erupt between the ages of 17 and 25. However, the eruption process can vary widely among individuals. Factors such as genetics, space availability, and local anatomical conditions can influence the eruption pattern of wisdom teeth. In some cases, wisdom teeth may fail to fully emerge or become impacted, leading to various dental problems.

  • Wisdom Teeth and TMJ Pain: Etiology and Correlation: The relationship between wisdom teeth and TMJ pain remains a subject of debate. Several potential etiological factors have been proposed to explain the association between the two:
  • Impaction: Impacted wisdom teeth, which fail to fully erupt, can create pressure and crowding in the dental arch. This may result in altered occlusion, muscular imbalances, and possible TMJ pain.
  • Infection and Inflammation: Impacted wisdom teeth can be more susceptible to infection and inflammation, leading to pain and swelling in the surrounding tissues. Inflammatory processes near the TMJ may contribute to TMJ pain.
  • Malocclusion: The presence of wisdom teeth can sometimes cause changes in occlusion, leading to an imbalance in the bite. Malocclusion can strain the TMJ and its associated structures, potentially resulting in TMJ pain.
  • Occlusal Changes: Wisdom teeth eruption or extraction can alter the occlusal relationship between the upper and lower teeth. Significant occlusal changes may affect the TMJ, potentially leading to pain and dysfunction.

While these factors suggest a possible correlation between wisdom teeth and TMJ pain, it is important to note that not all individuals with wisdom teeth experience TMJ pain, and not all cases of TMJ pain can be attributed to wisdom teeth.


The connection between wisdom teeth and TMJ problems is primarily related to the limited space in the jaw and the potential for impacted or improperly erupted wisdom teeth to create dental issues. If you experience any discomfort, pain, or suspect a relationship between your wisdom teeth and TMJ, it’s essential to seek professional dental care.
