Abstract
A composition and method is disclosed for fluoridating teeth using a two component dentifrice system in which the first component is stable, semi-solid, extrudable dentifrice composition containing a fluoride ion releasable hydrolyzable complex fluoride compound such as sodium fluorosilicate, in an aqueous vehicle in which a carrageenan gum having major kappa and lambda forms as the primary thickening agent and the abrasive is a silica providing an acid pH when slurried with water, and the second component is a semi-solid, extrudable dentifrice composition containing a calcium ion releasable compound and the abrasive and carrageenan gum in an aqueous vehicle. The first and second dentifrice compounds are maintained separate from the other until mixed for application to teeth.
