Abstract
An oral care implement having a visual indicator of depletion. In one aspect, the oral care implement comprises a body having a reservoir containing a composition including an oral care fluid and an indicator fluid, the oral care fluid being a different color than the indicator fluid and immiscible with respect to the indicator fluid; a delivery member formed of a capillary material; and the oral care fluid and the indicator fluid arranged within the reservoir so that upon the oral care fluid within the reservoir being substantially depleted, the indicator fluid is delivered to a visible portion of the delivery member by capillary action.
