Fluoride toothpaste is a common oral health product that contains fluoride, a mineral that is naturally found in soil and rocks and has benefits for protecting tooth health. The amount of fluoride in toothpaste is generally safe if used as directed, but too much fluoride can pose risks to health. Most individuals experience no negative effects of fluoride when they consume it in the small amounts found in dental products and drinking water. However, if swallowed in large quantities, fluoride can cause dental fluorosis, which is a condition that interferes with the development of tooth enamel and can result in white streaks on the teeth. Other potential side effects of excessive fluoride consumption include stomach upset, nausea, vomiting, and diarrhea. Fluoride-free toothpaste is a relatively new option that uses natural ingredients to clean teeth, but it is not capable of strengthening the teeth and inhibiting bacterial growth the way toothpastes containing fluoride are. When choosing a fluoride toothpaste, it is recommended to look for the American Dental Association’s seal of approval, which indicates that the toothpaste contains fluoride, has active ingredients to improve dental health, and does not have sugar in the flavoring agents. If you experience any side effects from using fluoride toothpaste, such as mouth or gum irritation, stained or pitted teeth, or an allergic reaction, you should contact your dentist or pharmacist promptly.
