Dental lasers were first introduced in the 1960s, but they were used mostly experimentally, until the 1990s when dentists started using lasers to treat different dental problems. The treatments provided by a dental laser are alternative treatments and the laser can be used in almost all of the fields in dentistry. The word LASER stands for ‘Light Amplification by the Stimulated Emission of Radiation’ and there are many different types of dental lasers on the market at the moment. In the last couple of decades, the studies and clinical trials about lasers in dentistry have grown immensely. It is considered that dental lasers provide a treatment that is much more comfortable for patients, less painful, more efficient, the recovery time is shortened, and the whole procedure is much faster.
