An oral care system includes a toothbrush and a dispenser detachably coupled to the toothbrush. The dispenser includes a chamber containing an oral care material. A compression device assembly includes an actuator operably coupled to a compression device movably mounted inside the dispenser. In one embodiment, the actuator may be a ratcheting rocker switch that alternatingly engages gear racks formed on the dispenser housing. Actuating the rocker switch imparts pivotable and indexed linear motion to the switch. This in turn axially translates the compression device in a first longitudinal direction thereby compressing and extruding the oral care material from the dispenser. The corresponding indexed movement of the compression device dispenses predetermined doses of the oral care material providing precise control over the amount of oral care material dispensed.
