Gel-Kam Gel is a 0.4% stable stannous fluoride gel that has been shown to be an effective decay-preventive home-use gel that can be of significant value when used as directed in a conscientiously applied program of oral hygiene and regular professional care. With regular use it also has been shown to relieve sensitivity in otherwise normal teeth. However, clinical effectiveness against plaque, gingivitis, or other periodontal indications has not been proven.
