Periodontal disorders such as disorders associated with a dental implant are treated. An average power for a laser is selected via a user interface on a tablet, along with a set of permissible laser parameters provided in response to the selected average power. A gingival trough or flap is created around the implant with the laser. Infected tissue is selectively ablated or denatured via photothermolysis, and a pocket is lased around the affected implant. Marginal tissues are compressed against the implant.

A dental procedure performed on target tissue without anesthetic or anesthesia including preconditioning the target tissue using a laser device constructed to produce light in a wavelength range of 2750 nm to 11500 nm, to provide an energy fluence in a range of 50 J/cm.sup.2 to 100 J/cm.sup.2, and to operate in a free running pulsed mode providing 60 m bursts at a frequency of at least 50 Hz. Preconditioning includes selecting a combination of average optical output power and preconditioning time to administer low level laser therapy. The laser device is adjusted to deliver light through the light guide of the laser device at the selected average optical output power. Light delivered through the light guide of the adjusted laser device is directed toward the target tissue for the selected preconditioning time providing analgesia to the target tissue. Oral tissue is removed from the preconditioned target tissue during analgesia.
