A hazed toothpaste which can effect dental remineralization and reduce caries formation. The toothpaste contains a binary fluorine-providing system which provides about 750-1225 ppm fluoride from sodium monofluorophosphate and about 50-1000 ppm fluorine from sodium fluoride and a synthetic precipitated siliceous polishing agent. The toothpaste is stabilized against gassing in an unlined aluminium tube by the presence of a dicalcium phosphate which exerts a hazing effect on the toothpaste. Dicalcium phosphate also reduces color fading when a water-soluble dye is present. Additional haze to permit opacification of the toothpaste may be introduced by the presence of an opacifying agent, such as titanium dioxide.

Hazed toothpaste

A dental cream composition containing a binary fluorine providing system which provides about 1000-1670 ppm (0.1-0.16% by weight) fluorine from sodium monofluorophosphate and sodium fluoride wherein sodium fluoride provides about 30-35% by weight of the fluorine in amount of about 300-580 ppm (0.02-0.058% by weight). The dental cream contains a vehicle for the binary fluorine-providing system and about 20-75% by weight of a dentally acceptable water-insoluble polishing agent consisting essentially of dicalcium phosphate intimately dispersed in the vehicle and in direct contact with the binary fluorine-providing system. The dental cream is effective in retaining soluble fluorine and soluble fluoride, in effecting reduction of enamel solubility and in remineralization of dental enamel.

Dental cream composition

An opacified dental cream which effects dental remineralization and reduces caries formation. The opacified dental cream contains a binary fluorine providing system which provides fluorine from sodium monofluorophosphate and from sodium fluoride, a synthetic precipitated silica containing up to about 1% by weight of alumina polishing agent and an opacifying agent.

Aqueous toothpaste containing abrasive particles of Bayer process alkaline alpha-alumina trihydrate which has been milled in the presence of a surface-modifying agent. Carboxylic acids containing a polar and a non-polar group and hydrophilic pyrogenic silica are surface-modifying agents. The toothpaste may be packaged in unlined aluminum tubes.

Dentifrices

Toothpaste containing abrasive particles of milled alpha-alumina trihydrate, alkali metal monofluorophosphate and alkali metal fluoride, the total fluoride corresponding to about 500 to 1000 ppm F, which toothpaste is compatible with an unlined aluminum container and is effective to reduce enamel solubility.

Dentifrices containing alpha-alumina trihydrate

A periodontal dental composition is disclosed comprising folic acid and a polishing agent which is principally dicalcium phosphate.

Periodontal dental composition

A periodontal dental preparation is disclosed comprising folic acid, a dentally acceptable water-insoluble polishing agent which reduces the soluble folic acid present in the preparation and a fluorine-containing agent which increases retention of soluble folic acid in said preparation, the fluorine-containing agent comprising an alkali metal fluoride, and alkali metal monofluorophosphate, or a mixture thereof.

Periodontal dental preparation

Toothpaste composition having desirable compatibility with an unlimited aluminum container, which toothpaste contains a polishing material comprising hydrate of alumina and an anionic phosphate mono- or di-ester.

Toothpaste compositions

Dentifrices containing milled alpha-alumina trihydrate which has been surface-treated with a higher fatty acid.

Toothpaste containing milled alpha-alumina trihydrate

An oral preparation comprising a dentally acceptable oral vehicle and dispersed therein a cationic antibacterial agent in amount of about 0.01-5% by weight based on the cationic portion thereof and about 0.05-5% by weight of an anionic phosphate ester surface active agent comprising a mixture of monoester of the formula ##STR1## wherein R is an alkyl group of 10-20 carbon atoms, n an integer from 1-6 and M is selected from the group consisting of hydrogen, alkali metal and ammonium, said oral preparation having a pH of at least 6.
