Feb: Fluoride Facts: What it is and why it's important

Dental health is crucial, and most of us have heard from a young age about the importance of brushing and flossing. However, one equally important element of oral hygiene is a little less known: fluoride. Fluoride is a mineral found in water. You may have had your dentist ask you about your source of water before, and this element is the precise reason for that. Tap water is the best source of natural fluoride.                                                     

Tooth decay happens when plaque builds up on teeth, breaks down sugars in our food and breaks through the enamel. If tooth decay is not stopped or treated, it leads to cavities. Fluoride works against tooth decay in two ways. First, it builds up teeth when it is ingested. And second, it protects teeth when plaque attacks the surface of the tooth (KidsHealth,org). According to a 2012 report by the Centers for Disease Control and Prevention, 60 percent of the U.S. population receives fluoridated water through their taps at home. Some communities have naturally occurring fluoride, and others add it at their water processing plants. If you have any questions regarding your community, ask your dentist.

Kids rarely have trouble reaching the proper level of fluoride, but occasionally a doctor or dentist might prescribe fluoride drops or supplementation. As soon as a child’s teeth come in, the parent or caregiver should start brushing the teeth with a small amount of fluoride toothpaste. For young kids, the amount should be a smear the size of a grain of rice. After age 3, the amount of toothpaste can increase to the size of a pea. Teeth should be brushed twice daily and, after the age of 6, the child may start using fluoride mouth rinse (ADA.org).

Because some fluoride is good, a lot of fluoride must be even better, right? Actually, this is not the case. Too much fluoride can lead to discoloring of the teeth, and the mineral is potentially hazardous in high doses (WebMD.com). Reaching toxic levels is very difficult, and while it is possible, it is unlikely. Always discuss any questions or concerns with your doctor or dentist.
