The harmless and infection-free low-level laser(LLL) is highly capable of suppressing inflammatory process, reducing pain, and promoting wound healing. Thus, LLL is widely utilized in several different treatments in clinical practice. Researchers have studied the effects of LLL, and found that this method can accelerate alveolar bone remodeling and increase the rate of tooth movement in animals. Several clinical trials have also enhanced the effi
