The Role of Fluoride in Preventing Tooth Decay: What You Should Know By Dr. Andrew Kelly
Tooth decay is one of the most common dental problems worldwide. A key component in the fight against tooth decay is fluoride, which can strengthen teeth and prevent cavities. For Dr. Andrew Kelly, knowing how fluoride works and how to use it effectively is important for maintaining healthy teeth.
How Fluoride Works
Fluoride works by enhancing the remineralization process, which is essential for maintaining strong teeth. When teeth are exposed to acids produced by bacteria in the mouth, the enamel, or the outer layer of the teeth, begins to lose minerals like calcium and phosphate.
This process is known as demineralization and is the first step toward tooth decay. Fluoride helps to reverse this damage by attracting these minerals back to the enamel, thus strengthening it and making it more resistant to acid attacks.
Other than that, fluoride also inhibits the growth of harmful bacteria in the mouth. Dr. Andrew Kelly states that by disrupting the bacteria’s ability to produce acids, fluoride reduces the risk of cavities forming in the first place.
Sources of Fluoride
Fluoride is found in various sources, making it accessible for people to use it in their dental care. One common source is fluoridated drinking water, which is available in many communities around the world. The addition of fluoride has been hailed as one of the most effective public health measures for preventing tooth decay.
Fluoride can also be found in many dental products, including toothpaste, mouth rinses, and professional treatments provided by dentists. Fluoride toothpaste is particularly effective because it provides a consistent source of fluoride to the teeth during daily brushing. For people at higher risk of tooth decay, dentists may recommend fluoride treatments or gels to provide more protection.
Safe Use of Fluoride
Lastly, excessive fluoride intake can lead to dental fluorosis, which causes discoloration of the teeth. To prevent this, use the correct amount of fluoride toothpaste—a pea-sized amount for children and a slightly larger amount for adults. For Dr. Andrew Kelly, parents should supervise their children’s brushing to ensure they do not swallow toothpaste.
