An automatic toothpaste dispensing toothbrush is provided including a toothpaste containment portion. Such toothpaste containment portion is constructed from a resilient collapsible elastomeric material and has a compartment for housing a tube of toothpaste. A toothbrush portion has an outboard extent with a plurality of bristles mounted thereon and extending downwardly therefrom. The toothbrush portion further has an inboard extent and a toothpaste conduit. Associated with the conduit is a first opening formed a bottom face of the outboard extent and a second opening formed in a rear face of the inboard extent. An interior surface of the second opening has a plurality of threaded grooves formed therein for releasably coupling with a toothpaste tube. As such, the tube of toothpaste may be screwably coupled to the toothbrush portion and further situated within the compartment of the toothpaste containment portion and the toothpaste containment portion and toothbrush portion coupled. A valve assembly includes a vertical linear bore formed in the top face of the inboard extent of the toothbrush portion. A post with an aperture formed therein is slidably situated within the bore of the valve assembly. A spring situated within the bore below the post. During use, the valve assembly has a raised unbiased orientation with the aperture of the post misaligned with the conduit to preclude the flow of toothpaste therethrough and a lowered biased orientation with the aperture of the post aligned with the conduit to allow the flow of toothpaste therethrough upon the squeezing the toothpaste containment portion.
