Soft Tissue Laser
The first laser specifically designed for dentistry was marketed in 1989. Since then, many dentists have integrated this technology into their practice, but clinics that offer dental laser treatments still represent a minority. However, the benefits for the patient are numerous.

How does dental laser work?
Dental laser is a device that emits very powerful, concentrated and monochromatic light, i.e. of a single colour (corresponding to a specific wavelength). Depending on the device used, the wavelengths of this light range from visible to infrared (invisible light).
The laser produces waves of photons (particles of light energy) and the absorption of this energy at a target tissue produces a thermal reaction that causes intracellular and intercellular changes.
Depending on the parameters of the instrument used and the optical properties of the tissue on which the laser is directed, a temperature increase occurs which leads to different results. For example, a temperature of 50ºC has the effect of neutralizing several bacteria. At 60ºC, the inflamed tissue present in periodontal disease can be removed. At this same temperature, hemostasis (stopping bleeding) can also be accomplished. Soft tissue incision and excision procedures, on the other hand, are performed at a temperature of 100ºC. In this case, it is the vaporization of water within and between the cells that allows the removal or removal of biological tissue.
When is soft tissue laser used?
The laser is used in several procedures:
The laser is also very useful: To obtain rapid coagulation following tooth extraction (stopping bleeding and sterilizing the alveolus), which limits the risk of alveolitis, hemorrhage and infectious spread;
In the treatment of periodontal disease: used as a complement to curettage-surfacing, it improves the effectiveness of the curettage-surfacing and reduces the presence of bacteria including a.actynomycetemcomitans, a bacterium involved in systemic diseases such as multiple sclerosis and coronary heart disease.
