Methods are described that provide controlled release of beneficial bacteria to the oral cavity. Such bacteria can subsequently colonize the oral cavity and displace or suppress the growth of pathogenic microorganisms. Described devices include a stabilized preparation of such beneficial bacteria and provide a consumable liquid, wet foam, or gel that includes such bacteria when used.

Dental pastes are provided which include: (i) a compound of Formula (I), (ii) a compound of Formula (II) or a pharmaceutically acceptable salt thereof, and (iii) a dental abrasive.

A tooth whitening kit and method of whitening teeth using the same. The method may include applying a tooth whitening composition directly to surfaces of a user's teeth, exposing the surfaces of the user's teeth to ambient air for a first period of time to form a film of the tooth whitening composition on the surfaces of the user's teeth, applying light to the surfaces of the user's teeth for a second period of time while the film of the tooth whitening composition remains on the surfaces of the user's teeth, ceasing application of the light to the surfaces of the user's teeth and leaving the film of the tooth whitening composition on the surfaces of the user's teeth for a third period of time, and removing the film of the tooth whitening composition from the surfaces of the user's teeth.

A tooth whitening and/or tooth sensitivity strip or film comprising: about 1-20 wt. % hydroxyapatite (HAP). A process for the manufacture of a tooth whitening strip or film, the process comprising at least the steps of: —mixing at least one or a combination of polyvinylpyrrolidone (PVP) polymers wherein the amount of the polyvinylpyrrolidone (PVP) polymers is greater than 75 wt. % of the film or strip; and —an amount at least about 1-20 wt. % hydroxyapatite (HAP); and —at least one or a combination of polycarbophils; —with water to provide an aqueous tooth whitening liquid; —applying the aqueous tooth whitening liquid to a substrate to provide a substrate carrying the aqueous tooth whitening liquid; —drying the aqueous tooth whitening liquid to provide a tooth whitening film on the substrate, said film having a thickness from about 50 pm to about 500 pm.

A cleaning composition for an oral appliance, including (A) and (B). (A) 0.05 mass % or more and 8 mass % or less of an anionic homopolymer or copolymer which has a mass average molecular weight of 2,000 or higher and 500,000 or lower and includes a constituent unit derived from (a1) an anionic monomer having a carboxyl group, a sulfo group, or a phosphoric acid group. (B) one or more surfactants selected from the group consisting of an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant.

An oral composition in the form of a lozenge or lollipop is provided. The composition comprises crosslinked polyvinylpyrrolidine (PVP), xylitol and Matcha green tea. A multi-layer lozenge or lollipop for neutralizing saliva and re-hardening tooth enamel is also provided. The lozenge or lollipop comprises an alkalinizing agent; a re-mineralizing agent comprising Matcha green tea; a base; a plasticizer; and a sugar alcohol, wherein the lozenge or lollipop upon oral administration raises the saliva pH from about 7 to about 10 in about 1 minute. Methods of making and treatment are also provided.
