A comprehensive oral hygiene device preferably having a multi-headed oral care brush disposed at one end of an elongated handle and a manufacturing process therefor. The oral care brush of the present invention has at least one head and preferably two heads which are disposed in angular, generally opposing coactive relationship to each other. Each of the opposing heads is integrally formed on an independently manufactured flexible arm and each arm is subsequently attached to the elongated handle. The attachment of the arms to the handle involves a secondary process called overmolding. Overmolding in this case involves the placement of the arms in a secondary mold in operative position against the end of the handle. Then, a soft, preferably rubber-like material is injected into the secondary mold and surrounds elongated portions of the arms and the handle. When cured and removed from the secondary mold, the rubber-like material secures the arms in operative position against the handle. The flexibility of the brush arms may be enhanced by the rubber-like material which allows some outward flexure of the arms. A preferred two-headed brush arrangement in which the two heads are disposed in opposing relationship to each other then provides for unobstructed movement of the brush heads down onto the gum tissue. A third head or other number of heads may also be incorporated hereon. A toothbrush may also be disposed on the opposite end of the handle. The overmolding of the brush arms with the elongated handle preferably provides a distension on the handle and improves grip. It also reduces debris collection areas and thereby avoid bacterial growth and odor.
