How to talk to patients about fluoride
Talking to patients isn’t always simple, particularly with a touchy, emotional subject like fluoride. But there’s a lot of confusing scientific jargon and convincing misinformation out there and it’s up to you and your team to help debunk the myths and reframe the conversation. If your patient expresses concerns or has questions about fluoride, the first and most important thing to do is
listen. While it can be easy to brush off concerns because of your own background, taking the time to acknowledge and understand your patient’s point of view can help lay the groundwork for a productive conversation rather than a debate. From there, asking what exactly they’ve heard and from what source can help guide you to the proper response.
What exactly is fluoride and what does it do?
Many patients are suspicious of fluoride because it sounds like a chemical, which can have negative connotations. While it may seem basic to a dental professional, addressing these misconceptions immediately can help patients see fluoride for what it actually is: a naturally occurring, beneficial mineral. Should a patient ask about fluoride, here are some basic facts to cover:
- Fluoride exists naturally in plants, air, water and the earth’s crust, as well as much of what we eat and drink daily.1
- It’s the only mineral scientifically and clinically proven to prevent cavities and is recognized as beneficial by the FDA, ADA, EPA and CDC among other agencies.2,3,4
- It works by holding onto calcium and phosphate (the building blocks of teeth) in the mouth, which increases the remineralization, or reinforcement, of weak enamel. It also replaces the normal, weaker enamel structure (hydroxyapatite) with a more decay-resistant version (fluorapatite).
- Because of its benefits, public drinking water has been fortified with fluoride for over 70 years – and has been shown to provide 20 percent more protection against tooth decay than brushing alone.1,3,5 The reason for this supplementation is similar to why we add Vitamin D to milk, or folic acid to breads and cereals – to help improve our health.
Fear of toxicity
Some of the main concerns patients have about fluoride are around toxicity.
These are completely valid concerns. The reality is that while fluoride at low levels is proven to promote healthy teeth, it’s also true that high concentrations of fluoride can be dangerous.
4 Rather than gloss over the facts, recognizing what too much fluoride can do – and how much is too much – can go a long way in improving patient acceptance and trust. Too much fluoride can cause dental fluorosis (streaks or spots on teeth that are purely cosmetic), or skeletal fluorosis (a very rare bone disease).
4,6,7,8 However, the amount of fluoride one would have to consume for either of these outcomes is
extreme, such as eating entire tubes of toothpaste or drinking multiple gallons of water daily.
6,8 When it comes to the fluoride added to water and how much is recommended for brushing teeth or used in clinical treatments, it’s all carefully measured to specific levels that prevent tooth decay (all of which are well below risk level). You can help patients think of it like the dosages on their medication or adding salt to a meal. You wouldn’t down an entire bottle of aspirin or dump a whole salt shaker over your dinner and expect no ill effects afterward – but use the right amount and you’ll see the benefits.
