If you’re at an unusually high risk of developing a cavity, your dentist may recommend having a fluoride treatment performed at the end of your next preventive dentistry visit. Of course, before you agree to this simple procedure, you should make sure that you have an accurate idea of what fluoride is and what it does for your teeth. Below is a closer examination of the link between fluoride and your dental health.

What is Fluoride?

Fluoride is a naturally occurring mineral that can be found in water as well as many different kinds of food. Research has found that exposure to fluoride can strengthen tooth enamel and lower the chances of cavities occurring. For this reason, fluoride is found in all toothpastes with the ADA Seal of Acceptance, and many communities add it to their water supply.

How Exactly Does Fluoride Benefit the Teeth?

As a consequence of daily exposure to the acids produced by oral bacteria, the enamel that protects your teeth regularly loses some of its minerals, which can cause it to weaken over time. Weaker enamel tends to be more susceptible to decay and physical damage.

Fortunately, fluoride can aid with remineralization, which is when the enamel regains the minerals it lost. This can strengthen your teeth and make them more resistant to cavities. In some cases, remineralization can even help reverse the earliest signs of tooth decay.

How Can You Be Sure That You’re Getting Enough Fluoride?

Once you understand the important role that fluoride plays in maintaining a healthy smile, you may be wondering how you can ensure that you’re getting enough of it. For most people, it’s as simple as brushing at least two times a day with fluoride-based toothpaste and drinking water that has been fluoridated. But if you aren’t getting enough fluoride in your everyday life, your dentist may recommend a fluoride treatment.

During a fluoride treatment, a highly concentrated fluoride gel or varnish is placed on your teeth. The process is completely painless and usually only takes a matter of minutes. In order to give your teeth a chance to absorb the fluoride, you will be told not to brush for at least four to six hours.

When it comes to maintaining a healthy smile, the importance of fluoride cannot be overstated. Take the time to review your everyday routine and make sure that you’re getting the fluoride that you need to keep your smile safe from decay.
