Abstract
The present invention relates to a composition, for inhibiting dental erosion, and the use thereof. The composition comprises an aqueous solution of hydrofluoric acid, in which the concentration of hydrofluoric acid is 0.05%-2.00% and the pH is between 2.5 and 4.5.
Claims11
A composition with active agent for inhibiting dental erosion, the composition consisting essentially of hydrogen fluoride, and at least one of a humectant, a binder a thickening agent, an abrasive agent, a surfactant and a flavoring agent, wherein the hydrogen fluoride is the only fluoride present and is present in an aqueous solution at a concentration of 0.1-1% (w/v), the pH of the aqueous solution being between 2.5 and 4.5, and wherein the active agent is un-dissociated hydrogen fluoride.
A dentifrice with active agent for inhibiting dental erosion of teeth caused by organic acids, the dentifrice consisting essentially of a liquid phase that is 10-99% by weight of water and humectants, and hydrogen fluoride as the only fluoride present, wherein the hydrogen fluoride present at a concentration of 0.1-1% (w/v), wherein the pH of the dentifrice is between 2.8 and 4.5, and wherein the active agent is un-dissociated hydrogen fluoride.
A gel composition with active agent for inhibiting dental erosion, the gel composition consisting essentially of (a) 1-2% of a thickening agent;
- (b) optionally one or more of a sweetening agent and a flavoring agent;
- and (c) hydrogen fluoride as the only fluoride present at a concentration of 0.1-1% (w/v), wherein the pH of the aqueous solution is between 2.5 and 4.5, and wherein the active agent is un-dissociated hydrogen fluoride.
