This article aimed to offer a comparative and systematic analysis of the main lasers used in dentistry—diode, erbium, and CO₂—focusing on their clinical indications, benefits, limitations, and implementation obstacles. Through a critical review of literature published between 2020 and 2025, the aim was to provide evidence-based tools for clinical decision-making and promote the rational and safe use of laser technology in modern dental practice. The methodology consisted of a systematic review that included studies selected through academic databases such as PubMed, Scopus, and Google Scholar. Relevant clinical data were extracted, grouped according to laser type, wavelength, clinical applications, observed advantages, and technical limitations. Diode lasers (800–980 nm) were shown to be effective in soft tissue procedures such as gingivectomies and frenectomies, offering good hemostasis and less postoperative pain. Erbium lasers (2780–2940 nm) were ideal for working in hard tissue, with minimal need for anesthesia and greater precision. Meanwhile, the CO₂ laser (10600 nm) was preferred in soft tissue surgery for its clean cut and coagulation capabilities. Finally, significant barriers were identified, such as the high cost of the equipment, the learning curve, and clinical variability, which hampered its widespread adoption.
