Abstract
A method for minimizing damage to gingival and periodontal tissue is provided through steps that include delivering a first composition containing a zinc salt to a receptacle, delivering a second composition containing a bicarbonate salt to the same receptacle, and transferring within five minutes of delivery to the receptacle the combination into the mouth onto the gingival and periodontal tissues. Where the compositions are semi-solid such as in a toothpaste and/or gel, the receptacle is ordinarily a toothbrush. Liquid compositions such as mouthrinses may employ an expectorant cup as a receptacle.
