An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

Provided are aqueous soluble tin phosphate complexes formed from a mixture comprising tin (II) fluoride and a pyrophosphate salt and oral care compositions comprising the complexes and uses thereof.

The invention relates to oral care compositions comprising a first stannous ion source, a second stannous ion source, wherein the second stannous ion comprises stannous pyrophosphate, and a source of zinc selected from zinc oxide, zinc citrate, zinc lactate, and combinations thereof, and a humectant system comprising glycerin and sorbitol, and a thickening system, as well as to methods of using and making these compositions.

An oral care implement having a head and a handle. A plurality of tooth cleaning elements extend from an exposed front surface of the head. The handle has an open thumb gripping passageway extending between an exposed first surface of the handle and an exposed second surface of the handle opposite the exposed first surface. The handle also has a plurality of slots defining open slot passageways from the exposed first surface of the handle to the exposed second surface of the handle. The open thumb gripping passageway may be defined by a ring component that is fitted into an aperture in a body component. The open thumb gripping passageway may be a void space in the handle. The open slot passageways may be elongated along the handle and may serve to reduce a total amount of virgin material needed to manufacture the oral care implement.

Disclosed herein are skin care compositions, comprising vitamin E (e.g., alpha-tocopherol), a thiourea derivative of histidine (e.g., ergothioneine), a vitamin B3 compound (e.g., niacinamide) and/or a pyrrolidone carboxylic acid and/or a salt thereof (e.g., sodium PCA) as well as to methods of using these compositions.

A tooth whitening apparatus which includes a container having a cavity containing a tooth whitening composition and an applicator assembly which includes a cap, a rod member coupled to the cap and protruding from a bottom end of the cap and having a longitudinal axis, an outer surface, and a distal portion, and an applicator tip coupled to the distal portion of the rod member. The applicator assembly is alterable between: (1) an attached state whereby the cavity of the container is sealed; and (2) a detached state whereby the applicator assembly is separated from the container to apply the tooth whitening composition onto a user's teeth. The outer surface of the rod member includes at least one vent groove that is elongated in a direction of the longitudinal axis to reduce a pressure in the cavity of the container when altering the applicator assembly into the attached state.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.

An oral treatment device that emits electromagnetic radiation onto surfaces of a user's teeth. The oral treatment device may include an intraoral mouthpiece and a handle extending therefrom, the handle containing the control circuitry required for operation of the device. The mouthpiece may include a lamp support structure, a lamp, a lens plate, and a guard component. The lamp may include an electromagnetic radiation source that includes a flexible sheet and a plurality of illumination elements located thereon. The illumination elements may be light emitting diodes printed with an electrically conductive. Additional electronic components such as a processor and a power source may also be included in the device.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a housing including a first housing portion having an inner surface that defines a first cavity and a second housing portion having an inner surface that defines a second cavity. The tracking attachment may also include a tracking unit configured to facilitate tracking at least one of a position, orientation, or movement of the oral care implement to which it is attached. A first portion of the handle may be positioned within the first cavity and a second portion of the handle may be positioned within the second cavity.
