| Summary: | Orthodontics is constantly seeking innovation towards mechanical efficiency and better oral-related quality of life during treatment. This narrative review aims to discuss novel scientific reports about light therapies and how they can optimize different stages of orthodontic intervention: before, during, and after treatment. Recurrent conditions that can be treated with laser devices are the removal of carious tissue, dentin hypersensitivity, and temporomandibular disorders. Evidence reveals that laser procedures accelerate health recovery, enabling individuals to initiate orthodontic treatment. Along orthodontic procedure, photobiomodulation therapy, is indicated for analgesia after appliance activations, repair of traumatic ulcers, and acceleration of tooth movement. Moreover, antimicrobial photodynamic therapy is well-indicated for effective decontamination of oral infections such as herpetic lesions and peri-implantitis. Finally, high-intensity lasers are good allies in removing brackets and reconditioning red esthetics. There are many benefits to the use of light sources in the orthodontic routine: simplicity of technique, ease of handling devices, minimal invasiveness, and patient comfort during procedures. It is essential that professionals develop a critical overview of technological advances, offering safe and evidence-based therapies. Recent advances indicate that laser therapies improve patient experiences during orthodontic treatment and minimize the side effects of clinical interventions.
