At Park Blvd Dentistry, we believe prevention is the foundation of lifelong oral health. That’s why we include fluoride treatments for free as part of every routine exam and cleaning — a benefit that sets us apart from many other practices. Recent headlines have once again brought fluoride into the national conversation; now with debates over water fluoridation policies and its role in public health. It’s a good time to revisit what we actually know about fluoride and why it matters
What is Fluoride and How Does It Work?
Fluoride is a naturally occurring mineral that strengthens tooth enamel and makes it more resistant to acid attacks from plaque bacteria and dietary sugars. It also promotes remineralization, allowing early decay to be reversed before it becomes a cavity.
This discovery was made in part thanks to a curious early 20th-century observation: in some U.S. towns children developed mottled, chalky white teeth (now known as dental fluorosis) but had remarkably low rates of tooth decay.⁵
Public health officials and scientists, including Dr. H. Trendley Dean of the U.S. Public Health Service, investigated and found that high naturally occurring fluoride levels in drinking water were responsible. This led to one of the most successful public health initiatives of the 20th century: adjusting fluoride levels in community water supplies to an optimal range — high enough to prevent cavities but low enough to avoid fluorosis.⁶
Today, the recommended level for community water fluoridation in the U.S. is 0.7 parts per million (ppm).⁷
Why Topical Fluoride Treatments Matter
Even patients with excellent brushing habits and diets can benefit from professional fluoride application. Topical fluoride is especially important if you:
- Have a history of cavities
- Experience dry mouth (xerostomia)
- Wear braces or orthodontic appliances
- Have exposed root surfaces
- Drink primarily bottled or filtered water (which may lack adequate fluoride)
In-office fluoride treatments use a concentrated varnish applied directly to the teeth. It’s quick, painless, and highly effective — with studies showing a 25% or greater reduction in caries when fluoride varnish is used regularly.³
What about Fluoride Safety?
Professional fluoride treatments are safe for both children and adults. The small amount used in the office is carefully measured and controlled. While there’s sometimes confusion about fluoride and toxicity, the levels used in dental settings are well within safe margins and are endorsed by public health authorities worldwide, including the CDC, ADA, and WHO.⁴
Our Philosophy: Prevention Shouldn’t Cost Extra
Many offices charge additional fees for fluoride application — particularly for adults — but we don’t. At Park Blvd Dentistry, we’re committed to providing comprehensive preventive care without upselling, because we believe that protecting your teeth today avoids more extensive (and expensive) treatments tomorrow.
