Abstract: A personal care implement, such as an oral care implement, that includes a body containing a supply of a fluid. A flow barrier is positioned with a first surface adjacent to the supply of fluid and a second surface opposite the first surface. The flow barrier allows flow of the fluid through the flow barrier for application to a biological surface when the flow barrier is compressed and prevents or inhibits flow of another fluid that is in contact with the second surface of the flow barrier through the flow barrier in a static state. In certain embodiments, the fluid in the supply may have a first viscosity and a first surface tension and the another fluid may have a second viscosity and a second surface tension such that one of the first and second viscosities and one of the first and second surface tensions are different from each other.

Abstract: An oral care implement with fluid dispensing system includes a head, handle, and intermediate neck. The head comprises plural tooth cleaning elements. A reservoir containing oral care fluid is fluidly coupled to an elastomeric valve nested between a pair of longitudinally spaced protective lamellas on the head. A depressible actuator button operates to dispense the oral care fluid from the reservoir through the valve to the tooth cleaning elements. The protective lamellas formed of elastomeric material are foldable to alternating cover the valve to prevent ingress of external fluids in the oral cavity of the user into the valve to minimize fouling of the fluid dispensing system. Laterally open areas between the lamella allow the oral care fluid to migrate outwards to the tooth cleaning elements. To control the dosage of oral care fluid dispensed, a modular system comprising interchangeable spacer inserts is usable to change and customize the dosage.

Abstract: A tooth sensitivity treatment device and an applicator tip thereof. The tooth sensitivity treatment device may be configured to dispense a sensitivity formulation onto a user's teeth. The tooth sensitivity treatment device may further be configured to massage the sensitivity formulation onto the user's teeth after dispensing. The applicator may have a bottom end, a top end, and a longitudinal axis extending therebetween. The applicator may include an application portion that is not intersected by the longitudinal axis. The application portion may have an outer surface that is oriented at an oblique angle relative to the longitudinal axis. The applicator may include a resilient material component and a rigid material component that are integrally coupled together. The resilient material component may form the entirety of the application portion to increase flexibility while massaging the sensitivity formulation onto the user's teeth.

Abstract: An oral treatment device and a method of using the same. The oral treatment device includes an intraoral mouthpiece configured for placement into a mouth of a user. The intraoral mouthpiece includes an arcuate wall having a front surface and a bite platform extending from the front surface. Furthermore, there is an alignment feature located on the bite platform to facilitate consistent positioning of the intraoral mouthpiece within the user's mouth in a repeatable manner. The alignment feature may have a top surface that is inclined upwardly moving in a direction away from the front surface of the arcuate wall. The intraoral mouthpiece may also include a color measurement sensor for obtaining a color measurement of a tooth of the user.

Abstract: A personal care system or fluid supply system with components specifically designed and arranged to speed up the process of initially priming an applicator of the personal care system with a fluid. The personal care system may include a personal care implement having an applicator and a fluid supply system disposed within the personal care implement. The fluid supply system may include multiple reservoirs, both filled with a fluid, and one of which has an absorbent member disposed therein. A first capillary member may extend from one of the reservoirs to the applicator and a second capillary member may extend from the reservoir with the absorbent member therein to the applicator. The fluid may travel faster along the second capillary member to speed up the priming process.

Abstract: An oral care device may include: a body including a head; a plurality of teeth cleaning elements extending from the head; a first electrode on the head; a second electrode on the head and spaced apart from the first electrode, wherein at least one of the first and second electrodes is a sacrificial electrode; a power source; and a controller configured to operably couple the power source to the first and second electrodes to create an electric potential between the first and second electrodes so that ions are released from the sacrificial electrode during a brushing session; wherein the controller is configured to change a magnitude of the electric potential the brushing session ends.

Abstract: 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.

Abstract: An oral cavity treatment device which may include a mouthpiece and a power cord which extends from the mouthpiece to a plug. The power cord may be coupled to an electronic device, such as a phone or computer, to provide power to the oral cavity treatment device. The mouthpiece may include a lamp having light emitters on a flexible sheet and a lens member covering the lamp. The light emitters may be provided in staggered rows to ensure adequate tooth coverage during use. The lens may include bite protrusions positioned on opposing ends of the lens. The lens may be incredibly flexible to accommodate any mouth shape. There may be a control unit with a power button and processor located at a position along the power cord that is closer to the plug than to the mouthpiece for enhanced comfort.

Abstract: A method of whitening teeth that decreases the amount of time that the whitening composition is in contact with the teeth. Specifically, by pretreating the whitening composition with light before contacting the teeth with the whitening composition, the amount of time that the whitening composition needs to be in contact with the teeth can be reduced. In one aspect, the method may include dispensing a tooth whitening composition from a reservoir device into a channel of a mouth tray; activating an electromagnetic radiation source to emit light onto the tooth whitening composition in the channel of the mouth tray for a first period of time to pretreat the tooth whitening composition; and inserting the mouth tray into the oral cavity of the user so that the user's teeth are in contact with the tooth whitening composition in the channel for a second period of time to whiten the teeth.
