What Is Fluoride?

Before answering your question: What does fluoride do in toothpaste? You need to know what fluoride is in the first place.

Fluoride is a naturally occurring mineral found in the Earth, particularly in soil and rocks. But it can also be found in small amounts in plants, the air, and water sources, like the ocean.

And of course, as you already know: It’s a common ingredient in dental care products, like toothpaste and mouthwash.

Even though it’s a “natural” ingredient, it doesn’t mean it isn’t toxic.


What Does Fluoride Do in Toothpaste?

Not many people wonder: “what does fluoride do in toothpaste?” while brushing their pearly whites. But we know you’re not like most people, so here’s your answer:

Your toothpaste contains fluoride because this ingredient improves your dental health. Not only does fluoride protect teeth against decay but it also helps repair tooth damage. And it makes this possible by promoting remineralization and protecting teeth against the opposite process: demineralization.

Don’t worry, we’ll explain how those processes work:

When you eat carbs and sugar, the bacteria in dental plaque produce acids that break down the hard outer layer of your teeth. This process is called demineralization and it’s the first sign of tooth decay.

The fluoride acts as a remineralization agent to speed up the growth of the new surface (which is acid resistant) to help repair tooth damage.

What Are The Benefits Of Fluoride?

Fluoride isn't all bad. Whilst a lot of people might want to avoid fluoride, it still certainly has a lot of benefits when used in your toothpaste and within the dental industry.


  • It strengthens the outer layer of your teeth (known as the enamel)
  • It can prevent the growth of harmful oral bacteria
  • It reverses early signs of tooth decay
  • It help to prevent cavities

Why Avoid Fluoride in Toothpaste?

If fluoride has so many benefits for your dental hygiene, you might be wondering: Why avoid fluoride in a toothpaste then?

Some people avoid fluoride in toothpaste because ingesting this mineral in large quantities can lead to dental fluorosis. This condition produces white lines or spots on the surface of your teeth. That said, this only happens if your teeth are still forming under your gums.

Yes, toothpaste is not meant to be ingested, but young children don’t know this! That’s why it’s recommended to supervise children while they brush their teeth.

There’s also another side effect of ingesting fluoride: Skeletal fluorosis.

Drinking water with high levels of fluoride or swallowing toothpaste over many years can lead to skeletal fluorosis. Common symptoms of this condition include joint pain and stiffness. But that’s not all, ligaments may calcify in severe cases, which cause pain and trouble moving!

Should You Use Fluoride-free Toothpaste?

Fluoride is the most effective ingredient to protect your teeth from cavities. And as long as you spit it out after brushing your teeth, it’s a safe option to keep your pearly whites healthy. But that’s a personal choice that has a lot to do with your age, fluoride needs, and preferences. So, here are some considerations you should keep in mind when choosing the right toothpaste for you and your family:


Fluoride And Children

Fluorosis usually affects children who are still in the teeth forming years. For young children, fluoride-free toothpaste would be a practical option to prevent them from swallowing fluoride. But if you prefer toothpaste with fluoride, check these recommendations:


  • Supervise children’s use of toothpaste to make sure they spit it out.
  • Children under the age of three shouldn’t use more toothpaste than a grain of rice. Also, their toothpaste should have a fluoride level of 1,000 parts per million (ppm).
  • Anyone ages 3 and older should use a pea-sized amount of toothpaste. Plus, their toothpaste should have a fluoride level of 1,350-1,500 ppm.

Fluoride And Adults

Fluoride-free toothpaste would be a good option for you if you’re allergic to fluoride. And if you’re unsure about using fluoride, you could ask your dentist what ingredients would be appropriate for your oral hygiene and preferences.

The good news is, you have options! Whatever you decide to go with, you will always be able to find toothpaste both with and without fluoride. Brushd, for example, has toothpaste tablets with and without fluoride, so you can pick up the one that works best in your routine, and they are great for travel.

And whilst we're on the subject, natural toothpaste these days is not only available with and without fluoride but also in tablets as well. A lot of choices - I know! So now you know what fluoride does in toothpaste, you can get back to figuring out whether you want toothpaste tablets or normal, natural toothpaste :)
