Claim 14:
15. A dental procedure for desensitizing target tissue in a client's mouth comprising an abfraction or a cervical lesion of a tooth without using anesthetic, anesthesia, or a chemical desensitizing agent, said procedure comprising the steps of:
selecting a laser device including at least one laser selected from a group of lasers consisting of an Er:YAG solid-state laser, an Er,Cr:YSGG solid-state laser, and a CO2 gas laser and a handpiece including a tip from which light produced by the laser is emitted, the fiber tip having a diameter in a range of 500 μm to 800 μm, said handpiece having a nozzle from which a spray comprising water and air is dispensed for cooling the target tissue in the client's mouth while light emitted by the fiber tip of the handpiece is directed toward the target tissue in the client's mouth, and said laser device including a flow control for varying a rate at which water is dispensed from the nozzle and a rate at which air is dispensed from the nozzle;
adjusting the flow control to dispense a spray comprising water at an initial water flow rate and air at an initial air flow rate;
while the flow control is adjusted to dispense the spray comprising water at the initial water flow rate and air at the initial air flow rate initial rate, directing light emitted from the fiber tip of the handpiece toward the target tissue in the client's mouth for a first period; and
after the first period, adjusting the flow control to decrease the water flow rate and the air flow rate while continuing to direct light emitted from the fiber tip of the handpiece toward the target tissue in the client's mouth for a second period.
