The unique nature of laser light and a specific and fundamental relationship between light wavelength and absorption by an 'illuminated' target tissue, led to an expansion of its use in medicine and dentistry. Despite the fact that in 1960, Theodore Maiman was assign for the invention of the first working laser, the possibilities for laser use in dentistry did not occur until 1989. The acceptance of lasers as possible alternatives to traditional methods in dentistry was one of the events that created great interest in the last decades. As, laser light is a unique non-ionizing form of electromagnetic radiation it can be employed as a controlled source for tissue stimulation, cutting or ablation, depending on specific parameters of wavelength, power and target tissue. With respect to the monochromatic nature of laser light, a number of emission wavelengths have been developed that, for the purposes of current clinical dentistry, span the visible to the far infrared portions of the electromagnetic spectrum, approximately 400-10,600 nm. Laser technology for hard tissue application and soft tissue surgery is at a high state of improvement, having had several decades of development, up to the present time, and further refinementcan occur.At low doses, laser application stimulates proliferation, while at high doses it is suppressive. It affects fibroblast maturation and locomotion, and this in turn may contribute to the higher tensile strengths reported for healed wounds.The scope of laser-based photochemical reactions offers great expectation for additional applications, particularly for targeting specific cells, pathogens, or molecules. A future growth in this area is expected to be a combination of diagnostic and therapeutic laser techniques. Looking forward in to the future, it is expected that specific laser technologies will become essential components of contemporary dental practice over the next decade. Kay words:laser light, dental laser, laser for hard tissue,laser for soft tissue
