摘要： This invention relates to a device for whitening teeth, comprising a dispenser (11, 311) equipped with a zone to be gripped (13) by the user and a nozzle (14, 314) for ejecting a flow of whitening product, characterised in that it comprises a tank (16, 316) of at least part of the whitening product, fixed to said dispenser (11, 311) in such a way as to move together with said dispenser during the movements of the hand of the user, and a pressure energy source (219, 319) of the type which can be used until finished (219, 319), designed to allow the whitening product to come out. The above-mentioned device comprises both a tank (16) for at least part of the whitening product in solid or semi-solid form, and a tank (17) of a product in liquid form and means designed to mix said products in powder form and in liquid form before they come out of said nozzle (14). The above-mentioned device also comprising a duct (18) leading to said nozzle (14) and operatively connected to said pressurised energy source (219) from which, on command, a flow of gas extends; operatively connected in an intermediate position of a first stretch (18A) of said duct (18) there being said tank (16) of at least part of the whitening product, therefore the passage of the flow of gas through said intermediate position of said first stretch (18A) of duct (18) causing the suction and intake into the duct of said at least part of the whitening product by Venturi effect; operatively connected in an intermediate position of a second stretch (18B) of said duct (18) there being said tank (17) of product in liquid form, therefore the passage of the flow of gas through said intermediate position of said second stretch (18B) of duct (18) causing the suction and intake into the duct (18) of said product in liquid form by Venturi effect; said at least part of the whitening product and said product in liquid form mixing before coming out of the nozzle (14).
