A film forming composition for coating teeth which is a mixture of about 0.5% to about 30% by weight of a film forming polymer; about 10% to about 99.5% by weight of solvent; about 0.05% to about 40% by weight of a rheology modifier; about 0.01% to about 5% by weight of a dispersant or plasticizer, if necessary; and optionally up to about 30% by weight of an opacifier or colorant.

Tooth coating composition

A blend of one or more crosslinked polymers or copolymers prepared from an olefinically unsaturated polymerizable carboxylic or anhydride monomer and at least one high molecular weight essentially linear polymer prepared from an olefinically unsaturated polymerizable carboxylic acid monomer. The blend is neutralized to typically a low pH, and generally contains a noncovalent, e.g. ionic, crosslinking agent, and a cure rate modifier. The hydrogel blend is capable of containing a large amount of water, has good tack, good adhesion, and can be utilized as an application vehicle having a backing thereon as well as containing various substances such as personal care compounds, pharmaceuticals, active ingredients, and the like. Conversely, the hydrogel blend can be dried and subsequently wetted without substantial loss of properties.
