Review on 🦷 Colgate Gel-Kam Fluoride Preventive Treatment - Gel Mint Flavor - 4.30 Ounce Tube, 1 Pack by Walter Harmon

I tried this product to desensitize and heal my front teeth which I suspect was mild decay. I used it morning and night for a month. It started working after the first few days and steadily improved until I felt very little sensitivity and no discomfort through the intended cavity. I didn't have any stains either, but I use whitening toothpaste. The only issue I had was that the company had sent me a coupon code to purchase a different product and the code didn't work. I have emailed them and am expecting the issue to be resolved. But the good news about the product is that I wanted to buy it again for my daughter so hopefully the code will work once I give the desired feedback or when they get my email. *I'm adding a fifth star here because customer service was extremely helpful and responsive and resolved my coupon issue immediately. I ended up buying two more of these. Great company, great product.
