[ I claim:] [8.]8. A toothbrush system, comprising:a disposable toothbrush, comprising:a housing having a reservoir portion and a head portion extending from said reservoir portion, said reservoir portion having toothpaste therein, said head portion having a plurality of bristles coupled to a bristled portion thereof;said head portion having a tube extending therethrough having an opening in said bristled portion and in communication with said reservoir portion, said toothpaste being forcible through said tube such that a portion of said toothpaste is dispensible onto said bristles;an ejection means for ejecting said toothpaste from said reservoir portion, said ejection means comprising a holed disc nonrotatably positioned in said reservoir portion and engaging said toothpaste, a threaded shaft threadedly engaging said holed disc and extending from a bottom of said reservoir portion towards said head portion, and a turn handle operatively coupled to said threaded shaft, said turn handle rotating said threaded shaft for selectively positioning said holed disc along said threaded shaft;said holed disc engaging an inner surface of said reservoir portion for forming a seal therewith;wherein said holed disc moves towards said head portion when said turn handle is rotated in a first direction with respect to said reservoir portion, said holed disc moving away from said head portion when said turn handle is rotated in a second direction;a first bristle cover removably coupled to said bristled portion; andsaid bristled portion of said housing having a peripheral edge, said first bristle cover having a peripheral groove extending around an outer rim thereof, said peripheral groove being adapted for receiving said peripheral edge of said bristled portion for frictionally holding said first bristle cover on said bristled portion;said reservoir portion having a length of about six and a half inches, said bristled portion having a length of about one inch and a width between about a quarter of an inch and a third of an inch, a distance between said bristled portion being about two inches, said turn handle having an outer diameter about half an inch for aiding in the operation and holding said turn handle; anda refillable toothbrush, comprising:a housing having a reservoir portion, a head portion detachably coupled to said reservoir portion, a bristled portion detachably coupled to said head portion, and a handle portion rotatably coupled to said reservoir portion;said bristled portion having a plurality of bristles coupled thereto, said bristled portion may have a plurality of bulbous protuberances extending for detachably attaching said bristled portion to similarly apertures in said head portion of said housing;said head portion having a tube extending therethrough having an opening in said bristled portion and in communication with said reservoir portion, said toothpaste being forcible through said tube such that a portion of said toothpaste is dispensible onto said bristles;a cartridge having an open top, an open bottom, toothpaste disposed therein, and an abutment disc positioned towards said bottom and engaging said toothpaste, said cartridge being insertable in said reservoir portion such that said open top is positioned towards said tube of said head portion;a generally conical resiliently deformable seal member positioned in said tube and engaging said open top of said cartridge for forming a seal between said open top of said cartridge and said seal member, wherein said seal has a bore therethrough for allowing passage of said toothpaste through said seal;an ejection means for ejecting said toothpaste from said cartridge, said ejection means comprising a plunger slidably positioned in said reservoir portion and engaging said abutment disc of said cartridge, a threaded shaft coupled to said plunger and extending from said reservoir portion into said handle portion through a threaded aperture in said reservoir portion, and a shaft housing fixedly disposed in said handle portion and nonrotatably engaging said threaded shaft, said threaded shaft being slidably positionable along said shaft housing;wherein said threaded shaft has a pair of lateral flanges extending from said threaded shaft, said shaft housing would have channels running along an inner surface of said shaft housing, said lateral flanges would slide along said channels preventing said threaded shaft from rotating with respect to said shaft housing and said handle portion;wherein said threaded shaft moves towards said head portion when said handle portion is rotated in a first direction with respect to said reservoir portion, said threaded shaft moving away from said head portion when said handle portion is rotated in a second direction;a friction ring positioned between said handle portion and said reservoir portion for resisting rotation of said handle portion with respect to said reservoir portion;a second bristle cover removably coupled to said bristled portion; andsaid bristled portion of said housing having a peripheral edge, said second bristle cover having a peripheral groove extending around an outer rim thereof, said peripheral groove being adapted for receiving said peripheral edge of said bristled portion for frictionally holding said second bristle cover on said bristled portion.
