Sodium Fluoride

Sodium Fluoride

Sodium fluoride is a chemical compound with the formula NaF. It is an inorganic salt, typically appearing as a white crystalline powder or colorless crystals. It is commonly used in various applications, including dental products, water fluoridation, and certain industrial processes.


Sodium fluoride is primarily used in dentistry to prevent dental cavities and strengthen tooth enamel. It is often added to toothpaste, mouthwash, and professional dental treatments.


The dosage of sodium fluoride varies depending on the specific product and intended use. It is important to follow the instructions provided by a healthcare professional or as indicated on the product label.


Sodium fluoride should be used with caution or avoided in individuals with known hypersensitivity or allergy to fluoride. Patients with certain medical conditions, such as renal impairment, may also require special consideration.

Special Precautions

Special precautions should be taken when administering sodium fluoride to young children to prevent excessive ingestion, which can lead to dental fluorosis or other adverse effects. Careful monitoring of fluoride intake is recommended, especially in communities with water fluoridation programs.

Side Effects

Common side effects of sodium fluoride include gastrointestinal disturbances such as nausea, vomiting, and abdominal pain. Long-term excessive intake of fluoride may lead to dental or skeletal fluorosis, characterized by mottling of teeth or bone abnormalities.

Drug Interactions

Sodium fluoride may interact with certain medications, such as tetracycline antibiotics, reducing their absorption. It is important to consult with a healthcare professional before using sodium fluoride concurrently with other medications.
