Why does SmartMouth Rinse come in a two bottle system?
Extensive time was devoted to properly formulate SmartMouth Rinse. Each bottle contains one of the major active ingredients. Keeping the active ingredients separate until just prior to use provides maximum protection against bad breath each time they are used. That is part of the SmartMouth Rinse patent and that is why SmartMouth Rinse can stop bad breath for 12 hours.
