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.

- (i) delivering a first liquid composition to a receptacle, the first liquid composition comprising from about 0.1 to about 10% by weight of zinc salt and from about 0.1% to about 10% by weight of peroxygen compound in a pharmaceutically acceptable carrier;
- (ii) delivering a second liquid composition to the receptacle, the second liquid composition comprising from about 1 to about 80% by weight of a bicarbonate salt in a pharmaceutically acceptable carrier;
- (iii) transferring from the receptacle into the mouth a combination of the first and second liquid compositions within five minutes of their delivery to the receptacle;
- and
- (iv) agitating the combination of first and second liquid compositions within the mouth against the gingival and periodontal tissues.
