ABSTRACT:
A two component dental composition is disclosed which eliminates or substantially reduces the discomfort and pain associated with dentinal hypersensitivity which composition comprises a first dentifrice component having a neutral pH in the range of about 6.5 to 7.5 buffered with a phosphate salt, a second dentifrice component having an alkaline pH in the range of 6.5 to 7.5 and at least one of the components containing a potassium ion releasable compound and a fluoride ion releasable salt, the first and second components being maintained separate from each other until dispensed and combined for application to teeth requiring relief from dentine hypersensitivity, whereby heightened desensitization is experienced by the user.
