A 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 xanthan gum is the major thickening agent and glycerin, sorbitol or mixtures thereof is the humectant, and the second component is a semi-solid, extrudable dentifrice composition containing a calcium ion releasable compound and an abrasive in an aqueous vehicle containing xanthan gum as the major thickener and glycerin, sorbitol or mixtures thereof as the humectant. The first and second dentifrice compounds are maintained separate from the other until mixed for application to teeth.
