June 15, 2023 · Ashely Notarmaso

What is a TENS unit, and how does it work for TMJ relief?

A TENS unit, or Transcutaneous Electrical Nerve Stimulation unit, is a portable electronic device that delivers low-voltage electrical currents to the body through electrode pads placed on the skin. It is commonly used for pain management, including TMJ (Temporomandibular Joint) relief.

Here’s how a TENS unit works for TMJ pain:

1. Electrode Placement: The electrode pads of the TENS unit are strategically placed on or around the jaw area, specifically targeting the TMJ region. The pads are typically positioned near the jaw joint or the areas where pain is felt.
2. Electrical Stimulation: Once the electrode pads are in place, the TENS unit generates electrical pulses or waves. These pulses are delivered through the electrode pads and penetrate the skin to reach the underlying nerves and muscles of the jaw joint.
3. Pain Gate Theory: The electrical stimulation provided by the TENS unit operates on the principle of the “Pain Gate Theory.” According to this theory, the transmission of pain signals to the brain can be interfered with or blocked by the introduction of non-painful stimuli. The electrical pulses from the TENS unit act as these non-painful stimuli, effectively closing the “pain gate” and reducing the perception of pain in the TMJ area.
4. Endorphin Release: The electrical stimulation also encourages the release of endorphins, which are natural pain-relieving chemicals produced by the body. Endorphins help to alleviate pain and promote a sense of relaxation and well-being. This can contribute to reducing TMJ pain and muscle tension associated with the condition.
5. Muscle Relaxation: TMJ pain is often related to muscle tension and spasms in the jaw area. The electrical currents emitted by the TENS unit can stimulate the muscles, promoting relaxation and reducing muscle spasms. By easing muscle tension, the TENS unit helps to relieve TMJ discomfort.

It’s important to note that while TENS units can be effective for many individuals in managing TMJ pain, results may vary. It is advisable to consult with a healthcare professional, such as a dentist or physical therapist, who can provide guidance on using a TENS unit for TMJ relief and ensure proper electrode placement and settings for your specific needs.
