Colgate Gel-Kam Preventative Treatment Gel is a great solution for anyone suffering with sensitive teeth. This brush-on gel contains 0.4 percent stannous fluoride, which both prevents and relieves hypersensitivity in teeth. Not only does stannous fluoride strengthen and fortify tooth enamel, it also occludes dentinal tubules. It sounds complicated, but all it really means is that you’ll be able to consume hot and cold food and drinks without wincing in pain. Colgate Gel-Kam can be used in conjunction with a low-abrasion toothpaste twice a day to further protect against sensitivity and decay. Consult your dentist for the best combination of treatments for your unique teeth. And look for Gel-Kam in both Fruit and Berry and Mint flavors from The Online Drugstore.
