An oral care implement including a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir, in the body, for storing an oral care fluid; and a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first check valve downstream of the reservoir, and a second check valve downstream of the first check valve and upstream of the fluid outlet. One of the first and second check valves comprises a valve seat defining an opening through which the oral care fluid is flowable, a valve member separate from the valve seat and comprising a stopper movable linearly relative to the valve seat, and a resilient element separate from the valve member and biasing the stopper towards the valve seat.
