Dental Pain, Infection and Tension in the Temporomandibular Joint

You have dealt with intense dental pain (odontalgia), perhaps from a cavity, an extraction or an infection. Your dentist has treated the primary problem, which is essential. However, have you noticed that, even after treatment, your jaw feels stiff, hurts when you chew or you hear clicking when you open your mouth?

At Fisioterapia en Colombia, we understand that acute dental pain is a powerful trigger of tension in the Temporomandibular Joint (TMJ).

When the pain is intense, your body reacts protectively: you tend to chew unevenly, clench your jaw or limit movement to avoid the discomfort. These compensatory patterns and the defensive muscle stiffness cause severe tension and dysfunction in the complex muscles that control the TMJ. The infection goes away, but the tension stays.


Why Does TMJ Dysfunction Persist After Dental Treatment?

Once the dental problem has been resolved, tension and pain in the jaw can continue as an aftereffect. This Craniomandibular Dysfunction (CMD) occurs due to several biomechanical factors:

  1. Persistent Muscle Spasm: Acute pain provokes an involuntary contraction (spasm) of the chewing muscles. Even though the dental cause has been resolved, the spasm can remain active, limiting mouth opening and causing pain referred to the head or the ear.
  2. Compensatory Chewing: By avoiding the painful tooth, you overload the muscles and the joint on the opposite side, creating a muscular and joint imbalance.
  3. Post-Procedure Tension: Long procedures (such as an extraction or a root canal) require keeping the mouth open for a long time, which can overstretch the ligaments and generate residual inflammation in the TMJ.

If after your dental treatment you still feel stiffness, clicking or persistent pain when opening your mouth, physical therapy specialized in the TMJ is the next and indispensable step toward a complete recovery.
