Tooth whitening device

Oral care implement

An oral care refill head and an oral care kit comprising the same. The oral care refill head may include a sleeve portion, a head portion, and an elastomeric prophy cup. The sleeve portion may have an inner surface that defines an internal cavity for receiving a portion of a stem of an oral care implement handle therein so that the oral care refill head can be repetitively attached to and detached from the oral care implement handle. The elastomeric prophy cup may comprise an outer surface that forms at least a portion of a peripheral side surface of the head portion. The elastomeric prophy cup may be formed by injection molding an elastomeric material onto a support portion of the head portion. The oral care refill head may be packaged together with a store of an anti-sensitivity oral care material to form a kit.

Oral care device

Oral cavity treatment device

A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.

Brush with fluid delivery

Electric toothbrush handle

An oral care implement handle or a refill head therefor. The refill head may include a sleeve portion extending from a proximal end to a distal end, the sleeve portion having an inner surface that defines an internal cavity. The internal cavity may extend along a sleeve axis from an open bottom end at the proximal end of the sleeve portion to a closed top end, the internal cavity being configured to receive an attachment portion of a stem of an oral care implement handle. The internal cavity may have a proximal section adjacent the open bottom end and a distal section adjacent the closed top end. The distal section of the internal cavity may include a central portion located on the sleeve axis and at least one slot portion radially extending from the central portion.

Oral care implement and handle and refill head thereof

Electric toothbrush

An oral care implement including a handle and a replacement head that is detachably coupled to the handle. The oral care implement may include a handle having a longitudinal axis that includes a gripping portion and a stem extending from the gripping portion. The gripping portion may have a shoulder that circumferentially surrounds the stem and an annular rib protruding from the shoulder. The replacement head may have a sleeve portion terminating in a proximal edge that is formed from a resilient material. The replacement head may be detachably coupled to the handle so that the annular rib of the shoulder and the proximal edge of the sleeve portion that is formed of elastomeric material are in contact with one another.
