The fluoride that is typically used in your water and toothpaste is a contaminated chemical byproduct that comes from the phosphate fertilizer manufacturing process. This toothpaste is fluoride free and Infused with oils that strengthen your immunity! 30% of which comes from oral health and cold and flu season is upon us! I have many clients who used Tom's toothpaste and switched to this as soon as they tried it! I won't use anything else. My teeth feel cleaner and I feel good about what's in it.
