Crest® Oral-B® recently introduced the Clinical Pro-Health™ System for Gingivitis, clinically tested to virtually eliminate gingivitis. The System includes Crest Pro-Health Clinical Gum Protection toothpaste, with newly balanced stabilized stannous fluoride chemistry that provides an increase in antibacterial power, resulting in our highest level of protection against plaque bacteria that cause gingivitis and helps reverse it after 4 weeks of regular use. The Clinical Pro-Health System for Gingivitis helps break the cycle of gingival inflammation and gingival bleeding for improved oral health in patients with mild to moderate, persistent gingivitis.
