  • Publication number: 20220409352
    Abstract: An oral treatment device for dispensing an oral treatment composition onto a user's teeth. The oral treatment device may include a storage and delivery component and an applicator component. The storage and delivery component may include a body having a reservoir, a frangible capsule containing the oral treatment composition located in the reservoir, and a delivery member. The applicator component may include a pad portion formed of a liquid absorbing material. The applicator component may be alterable between an attached state whereby the delivery member is fluidly coupled to the pad portion and a detached state whereby the applicator component is detached from the storage and delivery component and can be placed into contact with the user's teeth. The frangible capsule may be in a sealed state until broken by a user at which point the oral treatment composition may flow into the pad portion of the applicator component.
