Is Fluoride Safe?
A naturally occurring mineral, fluoride can strengthen tooth enamel to help prevent tooth decay. Those who are worried about the potential risks will be happy to learn that there are alternatives that can help fight cavities.

These days, one of the most highly debated topics is fluoride. But, just like everything out there, the internet and neighborhood groups can often be full of misinformation. As a dentist, I want my patients to be informed about the benefits of fluoride and it’s alternatives so they can make well-educated choices about using it – because although it is the gold standard, it’s not the only thing out there to strengthen and protect teeth! As a parent, I want the same thing! Whether you’re a crunchy-granola mom or a tiger mom or a soccer mom, we all want to keep our kids healthy and ensuring they have cavity-free teeth should be no different.
Fluoride
Fluoride is a mineral naturally found in the water, foods, and even the soil. When applied to the surface of teeth, it helps to harden tooth enamel and reduce the risk of decay. It can even re-mineralize teeth and reverse the early stages of a cavity! The regulation and addition of fluoride to therapeutic levels in city water supplies and toothpastes is largely considered one of the most successful public health initiatives in the United States.
However, too much fluoride - just like anything else - can be harmful. It can lead to brown spots on teeth, cause joint problems, and has even been linked to neurological and stomach issues. But don't worry - we all have the ability to choose when and how we use fluoride, so that we can take advantage of its decay-fighting abilities and minimize our chances of overuse.
Probably the most accessible way to get fluoride is by drinking and cooking with tap water. If you’re unsure if your city has fluoridated water, you can check online at: http://nccd.cdc.gov/doh_mwf.
The second easiest way to maintain regular fluoride use is through toothpastes and mouthwashes. There are even prescription strength fluoride toothpastes for patients who are at high risk for tooth decay or have increased tooth sensitivity not well managed with over the counter products.
For the kids and adults who don’t have access to fluoridated water or who avoid it’s daily use, or are simply high risk for cavities, professional application of fluoride at the doctor or dentist can be done once or twice a year!
Alternatives: Casein Protein and Hydroxyapatite Toothpaste
If you're looking for fluoride alternatives, there are actually products on the market that have been shown to have the same benefits! Casein proteins form a protective layer on the enamel of your teeth to prevent decalcification and strengthen them. When the tooth enamel is strong, it's hard for cavities to form! Casein is naturally found in milk and dairy products, but can also be found in MI Paste – a gel that can be used for brushing or applied directly to the teeth. MI Paste and MI Paste ONE Kids can be found online or purchased directly from your dentist!
Another alternative is hydroxyapatite toothpaste. This is one of the newest cavity-fighting products to enter the market. Hydroxyapatite is actually what the majority of your tooth is made of, so nano- and micro-hydroxyapatite products are non-toxic and biocompatible! Over-the-counter hydroxyapatite toothpastes include Boka, Risewell, and CariFree. Even better, they all have a line specifically for children!
There you have it - whether you choose to use fluoride or an alternative, the most important thing is to keep those teeth healthy and cavity-free.
