A brush head (25, Fig. 3), on the tip of a toothbrush sector (49, Fig.3), with bristle implants surrounding an orifice (26, Fig. 2) from where it is linked by an underlying tube (28, Fig. 2) to an accordion dentifrice cartridge (38, Fig. 2) via a mid-joint (39, Fig. 5). A needed amount of toothpaste can be infused onto the bristles bundles (22, Fig. 2) via the underlying tube by pushing the accordion bottom (40, Fig. 2). The brush head sector (49, Fig. 3) can be disposed at mid-joint (39, Fig. 5). Refill of toothpaste can be accomplished from a household tube by screwing on a suitable adapter (93, 94, Fig.7A and Fig. 7B). Additional designs: a switchable disposable brush-head plate (20, Fig. 9A) and a non- switchable brush-head plate (20A, Fig. 13B), mounting on a receptor (30, Fig. 10B), (30A, Fig. 13A) with an orifice (32, Fig. 12C), which links to an underlying tube (28, Fig. 10C), joining at one end with a male screw joint (48A, Fig. 10C) and a mid- joint (39, Fig. 5) on a handle, which houses an accordion cartridge (38, Fig. 6) for toothpaste. A motion of pushing forward or backward on the brush-head plate of a switchable brush- head plate will cause the brush-head orifice and the receptor orifice vertically connected or disconnected, thus opening and closing the thoroughfare of conveyance of dentifrice from the accordion dentifrice cartridge (38, Fig. 2) to the brush-head via an underlying tube (28, Fig. 2). All types of brush heads as well as a comb-brush head (102, Fig. 13E) are all interchangeable and disposable by screwing on and off at mid-joint (39, Fig. 5) or screw-joint (42, Fig. 11). Replenishment can be fulfilled by attaching an adapter to any domestic tube onto the mid-joint (39, Fig. 3) or the female screw joint (42, Fig. 11 ) into the cartridge (38, Fig. 11) or by replacing a new cartridge. Refill at the non-switchable is via the rear inlet (82, Fig. 13C)
