Abstract: A single-use disposable toothbrush assembly having an integral supply of toothpaste that is discharged into the bristles in response to the toothbrush head being pressed onto the handle of the assembly. The head includes a plurality of bristles and an internal chamber that contains a supply of toothpaste. A shaft portion of the handle is received in the chamber in sliding engagement therewith, so that in response to the handle member being pushed towards the head member an end of the shaft portion moves through the chamber so as to force the toothpaste out through at least one opening and into the bristles. The internal chamber of the head member is charged with a supply of toothpaste before the head is installed on the handle member and the assembly packaged for subsequent use.
