Why is Fluoride Good for the Teeth?
You may have heard dentists talking about topical fluoride and how good it is for the teeth. In fact, most toothpaste brands on the market today contain fluoride, and most people get their fluoride this way. Why is fluoride essential to your oral health? Here are some of the top reasons why you need fluoride for your teeth.
It prevents tooth decay
The mouth is full of bacteria that live on the teeth, gums, tongue, and other places in the mouth. Some of these bacteria are good. However, others are harmful and play a role in the tooth decay process. Harmful bacteria use sugars in food to make acids which erode the teeth and result in tooth decay. Fluoride in toothpaste reduces the ability of these bacteria to produce acids. It also makes the enamel resistant to acid attacks, hence preventing tooth decay.
It prevents formation of plaque
Plaque is a sticky, colorless film of bacteria that forms on the teeth due to poor oral hygiene. When you intake sugary foods and drinks, the bacteria within the plaque convert the sugars into acid. This acid dissolves minerals in the enamel such as calcium and phosphate in a process referred to as demineralization. Demineralization weakens the enamel and creates weak spots around the teeth, which could result in cavities. Fluoride helps remove plaque, and together with the minerals found in the saliva, restores minerals in the enamel. The process is referred to as remineralization.
It strengthens teeth in children
Tooth decay and cavities in infants and children can be attributed to the lack of fluoride in drinking water, food, and supplements, or in toothpaste. Exposure to fluoride is essential to children, especially during the development of permanent teeth. Fluoride is incorporated into the permanent teeth during development, protecting them from bacteria that cause tooth decay and cavity.
Most infants and children tend to swallow most of the toothpaste when brushing. High concentrations of fluoride in toothpaste can cause enamel fluorosis, a condition that's characterized by discoloration of the teeth due to excessive intake of fluoride. To prevent enamel fluorosis, small amounts of toothpaste should be used by infants each time. Also, supervision is necessary to discourage swallowing of toothpaste.
It treats certain health conditions
Certain oral health conditions can be addressed through increased exposure to fluoride. Such conditions include dry mouth conditions, gum disease, and frequent cavities and tooth decay. Your dentist can recommend additional topical fluoride from toothpaste, mouthwashes and rinses under these health conditions.
Fluoride plays a vital role in your oral health. By knowing its importance, you can include it in your daily oral hygiene routine for healthier and stronger teeth.
