There are installed a camera, display and a control panel respectively in central, upper and lower part of the said control box. Said toothpaste rack with several toothpaste drums fixed thereon is located to the right side of the control box. Said toothpaste drums include housings, and in the middle of the inner wall of the housings are mounted fixing brackets. On the fixing brackets are installed toothpaste extrusion pumps, above them are toothpaste entrances, and below them toothpaste exits. Below the fixing brackets are installed toothbrush hangers, and on the bottom of inner cavity of the toothbrush hangers squeezing buttons are fixed. The present invention analyzes the teeth images, estimates teeth conditions, and subsequently obtains an appropriate tooth care plan with the processor. ## Claims ### Claim 1 A method for automatically dispensing toothpaste for proper tooth care, comprising the steps of: providing a toothpaste rack upon which a plurality of toothpaste drums, respectively containing different types of toothpaste, are mounted; providing a plurality of toothbrush hangers mounted upon said toothpaste rack for respectively mounting a plurality of toothbrushes; providing a plurality of dispensing devices respectively operatively associated with said plurality of toothpaste drums for dispensing toothpaste from a particular one of said plurality of toothpaste drums onto a particular one of said toothbrushes when a particular one of said plurality of dispensing devices is actuated; providing a camera for capturing an image of a person's teeth; providing a processor having a database within which are stored different images of the person's teeth showing previous conditions of the person's teeth as previously captured by said camera; using said camera to capture a current image of the person's teeth so as to show a current condition of the person's teeth; using said processor to compare said current image of the person's teeth, as captured by said camera, with said different images of the person's teeth which are stored within said database and which show said previous conditions of the person's teeth; and using said processor to send a signal to a particular one of said plurality of dispensing devices for dispensing a particular one of said plurality of different types of toothpaste onto a particular one of said plurality of toothbrushes, depending upon said current image captured by said camera showing said current condition of the person's teeth, when compared to said different images of the person's teeth previously stored within said database and showing said previous conditions of the person's teeth, such that said particular one of said plurality of different types of toothpaste, as dispensed onto said particular one of said plurality of toothbrushes, can be used by the user in order to properly address said current condition of the person's teeth. ### Claim 2 (depends on 1) The method for automatically dispensing toothpaste for proper tooth care as set forth in claim 1, further comprising the steps of: providing a control box for housing said processor; and installing a storage battery within a bottom portion of said control box. ### Claim 3 (depends on 1) The method for automatically dispensing toothpaste for proper tooth care as set forth in claim 1, further comprising the step of: providing a plurality of indicator lights respectively associated with said plurality of toothbrushes for indicating which particular toothbrush is to be used by the person in order to properly brush the person's teeth. ### Claim 4 (depends on 1) The method for automatically dispensing toothpaste for proper tooth care as set forth in claim 1, further comprising the step of: providing a plurality of ultraviolet lamps operatively associated with said plurality of toothbrush hangers in order to maintain said plurality of toothbrush hangers clean. ### Claim 5 (depends on 2) The method for automatically dispensing toothpaste for proper tooth care as set forth in claim 2, further comprising the step of: providing a display panel mounted within said control box for displaying said image of said teeth captured by said camera. ### Claim 6 (depends on 1) The method for automatically dispensing toothpaste for proper tooth care as set forth in claim 1, further comprising the step of: providing a plurality of transparent vinyl covers are disposed around toothpaste outlets of said plurality of dispensing devices. ### Claim 7 (depends on 1) The method for automatically dispensing toothpaste for proper tooth care as set forth in claim 1, further comprising the step of: providing a plurality of suction cups mounted upon a rear side of said rack so as to permit said automatic toothpaste dispensing device to be mounted upon a wall.
