When used for surgical and dental procedures, the laser acts as a cutting instrument or a vaporizer of tissue that it comes in contact with. When used in teeth-whitening procedures, the laser acts as a heat source and enhances the effect of tooth-bleaching agents.

Laser Dental Therapy Extremely focused light beams that can be used to alter or remove tissues in small amounts. Dentists use lasers in many different procedures inside of the mouth. Lasers can be used to remove overgrown tissues, whiten teeth, or reshape the gums.
Laser Treatment is Safe/Unsafe? Compared to the traditional dental drill, lasers: May cause less pain in some instances, so reduces the need for anesthesia. May reduce anxiety in patients uncomfortable with the use of the dental drill. Minimize bleeding and swelling during soft tissue treatments.
Types Hard tissue laser: Hard tissue lasers can cut through tooth structure. These lasers are most often used to prep or shape teeth for composite bonding, to repair dental fillings that have worn down, and to remove some tooth structure. Soft tissue laser: Soft tissue lasers seal nerve endings and blood vessels while they penetrate the tissue. For this reason, many experience almost no pain after laser treatment. The lasers also promote faster healing of the tissue. These lasers are used to treat periodontitis, including killing bacteria and activating tissue regrowth.
Hard Tissue Procedures: Cavity detection Tooth preparations and dental fillings Treating tooth sensitivity. Soft Tissue Procedures: Treating a “gummy smile” Crown lengthening Treating tongue frenulum attachment Removing soft tissue folds.
Benefits Treatment done using soft tissue dental lasers may not involve stiches. Some procedures do not need anesthesia. Reduces gum bleeding during laser dentistry as compared to others. Bacterial infections are reduced also minimizes the surrounding tissue damage. Tissues can be regenerated and wounds heals faster.
Disadvantages Hard lasers can sometimes injure tooth pulp. Certain procedures can’t be done with laser treatment, depending on the preexisting surrounding tissue or components involving the tooth or gums. There is a risk of gum injury. Lasers can’t be used on teeth that already have certain types of filling, such as metal amalgam.
