The toothbrush assembly of claim 14, wherein said lid for closing the open side of the cover is secured to the cover by a snap-fit connection, so as to secure the lid to the cover. 18. The toothbrush assembly of claim 1, further comprising a source of bactericidal radiation in the cover arranged to irradiate the bristles. 19. In combination, the toothbrush assembly of claim 18 and a docking station comprising a power supply for said source of bactericidal radiation and connection means for energizing said source of bactericidal radiation when said toothbrush assembly is returned to said docking station. 20. The toothbrush assembly of claim 1, further comprising an ultrasonic vibratory source disposed in the body of the toothbrush. 21. The toothbrush assembly of claim 20, further comprising batteries for powering said ultrasonic vibratory source. 22. In combination, the toothbrush assembly of claim 21 and a docking station comprising battery charging circuitry and connection means for charging said batteries when said toothbrush assembly is returned to said docking station. 23. The toothbrush assembly of claim 1, wherein said cover comprises a back wall and a continuous side wall joined to the periphery of said back wall, said side wall including opposed sides and opposed ends, and wherein at least the sides of the cover are porous. 24. The toothbrush assembly of claim 1, wherein the body of the toothbrush, the elongated connector, and the bristle cover are molded of one or more plastic materials. 25. The toothbrush assembly of claim 24, wherein said plastic materials are selected from the group consisting of low or high density polyethylene (PE), low or high density polypropylene (PP), and polyvinylchloride (PVC). 26. The toothbrush assembly of claim 1, further comprising means for retaining the cover over the bristle head. 27. The toothbrush assembly of claim 26, wherein said means for retaining the cover over the bristle head comprises a C-shaped clip secured to the elongated connector and adapted to grip the body of the toothbrush and secure the cover over the bristles. 28. The toothbrush assembly of claim 1 wherein the cover includes a drain hole. 29. The toothbrush assembly of claim 1, wherein said lid of the storage compartment is pivotably coupled to the elongated toothbrush body and fits essentially completely flush with a surface of the toothbrush when the lid is closed. 30. The toothbrush of claim 29, wherein protrusions on one of the lid and body of the toothbrush cooperate with recesses formed on the other of the lid and body of the toothbrush so as secure the lid in the closed position, closing the storage compartment. 31. The toothbrush of claim 29, wherein the pivotable coupling between the lid and body of the toothbrush is formed by a hinge. 32. The toothbrush of claim 1, wherein a drainage opening is provided in the storage compartment. 33. The toothbrush assembly of claim 1, wherein said cover and elongated connector are molded as an integral member. 34. A method of protecting bristles of a toothbrush, comprising the steps of: a. providing a toothbrush assembly, comprising: an elongated toothbrush body having a bristle head at one end and a handle at a second end, the handle comprising a storage compartment, the storage compartment comprising a lid, wherein the lid is operably coupled to the storage compartment so as to allow the storage compartment to be opened and closed as desired;a cover comprising an open side enabling the cover to be placed over the bristle head;an elongated connector comprising a first end pivotably coupled to the toothbrush body between the bristle head and the storage compartment and a second end operably coupled to the cover, whereby the cover is movable between a first position wherein the open side of the cover faces the bristle head and the cover is disposed over the bristles to protect them when not in use and a second position wherein the cover is protected within the storage compartment by closing of the lid when the brush is in use;means for selectively retaining the cover in the first or second position;b. when it is desired to employ the brush, removing the cover from the bristle head, pivoting the elongated connector such that the bristle head is disposed in the storage compartment, and closing the lid of the storage compartment; andc. when employment of the brush is complete, opening the lid of the storage compartment, removing the cover from the storage compartment, pivoting the elongated connector so that the open face of the cover is over the bristle head, and securing the cover over the bristle head. 35.
