Fluoride stands as the most effective tool for preventing tooth decay. This essential mineral occurs naturally in almost all foods and water sources, and its benefits have been recognized for more than 50 years by health experts and professional organizations alike.
How Fluoride Protects Your Teeth
Topical fluoride works by strengthening teeth after they have erupted. It penetrates the outer layer of tooth enamel, making teeth more resistant to cavities. Topical fluoride is commonly found in dental products like toothpaste, mouth rinses, and gels. Dentists and dental hygienists typically recommend professional fluoride applications for children twice a year during routine check-ups.
Systemic fluoride helps protect both teeth that have already emerged and those developing beneath the gums. We receive systemic fluoride from a variety of foods and most community water supplies. It also comes in supplement form—such as drops or tablets—available by prescription from your dentist or physician. Drops are generally recommended for infants, while tablets are suitable for children and teens. It’s important to monitor how much fluoride a child consumes; excessive intake during tooth development can lead to fluorosis, a condition marked by white spots on the teeth.
While most people get some fluoride from food and water, the amount may not be sufficient to fully guard against decay. Your dental professional may suggest additional home or in-office fluoride treatments for reasons such as:
- Deep pits and grooves on chewing surfaces
- Exposed and sensitive tooth roots
- Poor or inconsistent oral hygiene
- Frequent consumption of sugary or starchy foods
- Low fluoride exposure
- Reduced saliva flow due to medications, medical treatments, or certain health conditions
- A recent history of cavities
It’s important to remember that fluoride alone cannot prevent tooth decay. Be sure to brush at least twice a day, floss regularly, eat a balanced diet, limit sugary snacks, and maintain regular dental visits for optimal oral health.
