Laser dentistry can also be applied in oral cavity surgery and treatment of gum disease using the yttrium aluminium garnet (Nd:YAG) laser. For a carbon dioxide laser, it works best when used for biopsies, the removal of tumors of the mouth, and in frenectomy or the surgical removal of the fold of tissue under the tongue.
