What is Fluoride for?

Fluoride is a form of the chemical element fluorine. In dentistry, fluoride is used to prevent and treat tooth decay. It protects the teeth from decay by binding with dissolved minerals and repairs the damaged tooth.

In Hong Kong and many cities, a small amount of fluoride is added to the water supply to prevent tooth decay in the community. Most kinds of toothpaste and mouthwashes include fluoride as one of the active ingredients. Typically, toothpaste has a minimal fluoride concentration of 1000 ppm.

How to use it?

Fluoride is available as toothpaste and mouthwash for the prevention of tooth decay. It is recommended to brush teeth twice daily with fluoride toothpaste.

Mouthwash is recommended for adults and children over 8 years old who have tooth decay. Mouthwash should be used every day at different times to brushing to avoid washing the fluoride from your toothpaste off your teeth. Rinse your mouth with 20ml of mouthwash for 30 seconds and spit out the mouthwash.

For those with insufficient intake of fluoride, the doctor may prescribe chewable fluoride tablets. Chew the tablet thoroughly and swallow, usually once daily or as directed.

What are the side effects of Fluoride?

Common side effects of Fluoride include teeth discoloration, hypersensitivity and rash.

Who should not take Fluoride?

– People allergic to Fluoride and any components of the formulation.

Pharmacist Tips:

– Spit out the mouthwash and avoid swallowing it because mouthwash contains ingredients that can be harmful if consumed in large quantities. It is, however, safe if you accidentally swallow small amounts.
– Avoid using mouthwash right after brushing teeth, since this may wash away the fluoride from your toothpaste.

Common dosing schedule:
Brush your teeth once in the morning and once at night.

This schedule is for reference only, adjustments may be made according to individual needs.

Some common medications Fluoride may interact with:
Fluoride has no known interactions with common medications.
