A method and a device are described for producing the whitening of live teeth with pathological and normal colorations, destined to whitening any tooth with normal color and furthermore eliminating the pathological coloration produced by aetiologies of different origin. The whitening of the teeth (6) is effected applying different chemical products to the dental enamel, covering the teeth to be treated with a metallic plate containing an absorbent material with a chemical whitening product which acts in the presence of heat and provokes the reaction of said product which will act on all sides of the dental drown, producing whitening of the teeth. The device is constituted, in essence, by a whitening device, comprised by a thermic heating unit, whether or not controlled by microprocessor, heating elements, temperature, time and alarm sensors and controls.

A method for whitening a live tooth or for simultaneously whitening a plurality of live teeth, said tooth or teeth containing colorants which impart to the tooth or teeth a color or colors, said tooth or teeth having enamel and enamel tubules, said tubules containing water or water vapor, said method comprising acid engraving the enamel to open the enamel tubules and extracting the water or water vapor from the tubules, covering the tooth or teeth with a metallic plate having an absorbent material containing a chemical whitening agent so that the tooth or teeth is covered by the plate with the absorbent material in contact with the tooth or teeth, said whitening agent being effective to react with and destroy the colorants when activated, heating the plate to cause the whitening agent to be heated to a temperature sufficient to activate it, and causing said absorbent material to be pressed against the tooth or teeth so as to cause the activated whitening agent to be released into the tubules and to diffuse through the tubules to the enamel-dentine junction of the tooth or teeth whereby to react with and destroy the colorants and thereby to whiten the tooth or teeth.
