What is Fluoride?

“Fluor,” found in toothpaste and other dental care products, refers to fluoride (fluor does not occur in its pure form but in various minerals and chemical compounds). Fluoride has proven to be extremely important for good dental health and has become an integral and natural part of modern dental care. The use of fluoride is largely credited for the significant reduction in cavity problems in modern society.

How Does Fluoride Work on Teeth?

Fluoride is an effective tool for preventing cavities. Through fluoride-containing products, it gets stored in the enamel and strengthens it against attacks from bacteria. This helps prevent the development of early cavities and protects against the formation of new ones.

Who Needs Fluoride?

In principle, everyone benefits from fluoride, but most people can achieve adequate protection by brushing their teeth twice a day with fluoride toothpaste. However, if you struggle with high cavity activity or dry mouth, additional supplementation may be necessary. This is something you can discuss with your dentist or dental hygienist.

Which flour is best?

There are many products that contain fluoride. For most people, brushing twice a day with fluoride toothpaste is sufficient, as mentioned earlier. If you plan to use other fluoride products in addition, be sure to read the packaging and follow the dosing instructions provided—or as agreed upon with your dental hygienist.

Fluoride Mouthwash:

A quick and effective option that offers extra protection. There is a wide variation in the amount of fluoride in different mouthwashes, so it’s essential to find one that best meets your needs. Your dental hygienist can help you with this. Mouthwash is typically used in the evening to allow the fluoride layer to remain on the teeth throughout the night. If you use mouthwash in the morning, it’s recommended to wait at least an hour before eating or drinking.

Fluoride Tablets:

These are a good option for children who cannot rinse without swallowing the mouthwash. For optimal effect, the tablet should be sucked rather than chewed. If you’re unsure whether your child needs to use fluoride tablets, consult your dental hygienist or dentist. Adults can also use fluoride tablets, which come in various fluoride contents and flavors.

Chewing Gum or Lozenges with Fluoride:

These can be suitable for dry mouth patients who are particularly susceptible to cavities. They can be a nice way to provide extra protection for your teeth throughout the day.

Toothpaste with Extra Fluoride Content:

If you have dry mouth, reduced ability to brush effectively, or other conditions affecting your oral health, you can find both prescription and over-the-counter toothpastes at the pharmacy that contain higher levels of fluoride than those available in stores. It’s a good idea to discuss this with your dental hygienist or dentist if you continue to experience oral health issues.

Fluoride Gel:

For some, there may also be a need for a fluoride gel that is applied in a custom-made tray fitted over the teeth. This is prescription-only, and the tray is made by the dentist.

Fluoride can strengthen tooth enamel and protect the nerves within the teeth from temperature changes and other influences. Other causes of tooth sensitivity may include damage such as cracks in the tooth, acid erosion, and cavities, which fluoride can also help prevent. If damage has already occurred, we recommend scheduling an appointment with your dentist to evaluate any necessary treatment options. Ask your dental hygienist about which toothpastes are recommended and may be effective against tooth sensitivity.

How Often Should You Use Fluoride Supplements?

For most people, brushing with fluoride toothpaste twice a day is sufficient, while others may require additional fluoride supplements. This need is highly individual and something you should discuss with your dentist.

Is Fluoride Dangerous?

Fluoride can be a beneficial addition to good oral health but should always be taken in recommended doses. The “fluoride” found in toothpaste and other oral health products is actually fluoride (fluorine does not occur in its pure form, but in several minerals and chemical compounds). These products contain very little fluoride, and according to scientific consensus, there is nothing to fear when brushing your teeth, unless you swallow very large amounts of toothpaste.

Fluoride for Children and Pregnant Women

For children, it is particularly important to adhere to the recommended dosages of fluoride. Fluoride supplements for children are tailored to their needs, but they should be stored out of reach of children. Excessive fluoride use before the enamel is formed, typically around the ages of 5-6, can negatively affect enamel development and, in rare cases, lead to dental fluorosis. Dental fluorosis appears as white or brown spots on the enamel. This is not a widespread issue in Norway, as drinking water contains very little fluoride, and the products sold here are adapted to Norwegian conditions.

During pregnancy, some individuals experience morning sickness and may vomit for a period of time. For most, this is a short-term issue, but for some, it can last for significant portions of the pregnancy. This can lead to increased exposure of the teeth to acid damage, raising the need for fluoride supplements. Feel free to consult your dentist or dental hygienist about this.
