How does dental laser work?

A dental laser is a device that emits very powerful, concentrated and monochromatic light, that is, of a single color (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 energy).

In what context is the soft tissue laser used?

  • The laser can be used for several procedures:
  • Gingivectomy (removing part of the gum for aesthetic reasons, hyperplasia or as part of periodontal treatment);
  • Gingivoplasty (reshaping the outline of the gums);
  • Operculectomy (removing part of the gum that covers an erupting tooth);
  • Frenectomy (surgical excision of a frenulum or membranous muscle attachment such as the lingual frenulum (net under the tongue) and labial frenulum (net located between the inside of the lip and the gum). This procedure can improve speech and eating habits in babies, children and adults;
  • Treatment of lesions due to herpes and aphthous ulcer;
  • The removal of benign lesions on the lip, tongue, oral mucosa or the palate area (eg: a fibroid or papilloma);
