A toothbrush assembly comprising:

• a head component comprising
• a first body member having a first cavity extending within the first body member from a rear end portion of the first body member, and a plurality of holes configured on a front end portion of the first body member, the plurality of holes fluidically coupled to the first cavity, wherein the first cavity includes a first diameter at the rear end portion and a second diameter at the front end portion, where the first diameter is greater than the second diameter and a segment of decreasing diameter where said segment of decreasing diameter starts at the first diameter and decreases to the second diameter, and
• a plurality of bristles configured on the front end portion of the first body, the plurality of bristles surrounding the plurality of holes;
• a handle component detachably attached to the head component, the handle component comprising
• a second body member having a second cavity extending within the second body member from a proximal end portion to a distal end portion of the second body member,
• a rotatable member coupled to the distal end portion of the second body member, and
• a first turning lug coupled to the rotatable member in a manner such that the first turning lug is disposed within the second cavity of the second body member;
• and
• a toothpaste cartridge removably received within the handle component, the toothpaste cartridge comprising
• an enclosure member capable of being received within the second cavity of the second body member, the enclosure member storing toothpaste therein,
• a rod member positioned longitudinally within the enclosure member,
• a second turning lug coupled to an end portion of the rod member and disposed outside the enclosure member, the second turning lug operatively coupled to the first turning lug, and
• a plunger member movably mounted on the rod member,
• wherein the plunger member is adapted to move along the rod member upon rotating the rotatable member for dispensing the toothpaste from the enclosure member to the first cavity of the first body member, thereby receiving the dispensed toothpaste by the plurality of bristles through the plurality of holes.
