To promote healing of the chronic inflammation and pain caused by long-term dental imbalances, part of the TruDenta therapy system uses low-level cold laser therapy. The painless treatment is shown to decrease pain, accelerate healing of muscle and joint tissue, as well as improve range of motion. Microcurrent therapy applies a painless low-level electrical current to areas of pain or sensitivity, which reduces the spasms of inflamed muscles, stimulates the nerves, and reduces lactic acid build up. Microcurrent therapy is used in conjunction with the low-level laser . It is particularly effective in restoring normal range of motion to patients whose dental imbalances include restricted jaw movement.
