What is generic sodium fluoride?

US brand name of sodium fluoride and manufacturer

Sodium fluoride is approved by the FDA to help prevent dental cavities in the U.S.

Prescription requirement for sodium fluoride

Sodium fluoride is available as an over-the-counter dental product. It does not require a prescription for use.

Active ingredient of sodium fluoride and mechanism of action

Sodium fluoride is an inorganic compound and the active ingredient in NaFrinse. It works by incorporating fluoride ions into the structure of tooth enamel, which helps to strengthen the teeth and prevent tooth decay. Fluoride also has antibacterial properties that can inhibit the growth of bacteria responsible for dental cavities.

Uses of sodium fluoride

Sodium fluoride (NaF) is used as an oral or topical form for the prevention of dental caries (tooth decay) and the remineralization of tooth enamel. It is commonly used as part of a comprehensive oral hygiene routine to enhance the effects of regular tooth brushing and flossing. Fluoride salts may be added to drinking water to help maintain dental health in the population.

Forms of sodium fluoride

Sodium fluoride is available as an oral rinse and in toothpaste. The specific concentration of sodium fluoride in the product may vary.

Dosage of sodium fluoride

The recommended dosage of sodium fluoride  may vary depending on the concentration of sodium fluoride in the product. It is important to follow the instructions provided on the product label or as directed by your dentist or healthcare professional. Take sodium fluoride 1 hour apart from foods such as dairy products containing calcium, aluminum, or magnesium, as well as certain antacids, laxatives, and vitamins or minerals. These can bind with fluoride, stopping it from being absorbed.

Precautions and warnings for sodium fluoride

  • Sodium fluoride  should be used as directed and not swallowed excessively to avoid the risk of fluorosis
  • It is important to supervise children during the use of sodium fluoride  to ensure proper use and avoid excessive ingestion
  • If you experience any adverse reactions or allergic symptoms while using sodium fluoride , discontinue use and seek medical advice
  • Inform your dentist or healthcare professional about any underlying medical conditions or medications you are taking before using sodium fluoride

Side effects of sodium fluoride

When used as directed, sodium fluoride  is generally well-tolerated. However, excessive ingestion or improper use may lead to adverse effects such as fluorosis, which can cause discoloration or mottling of the teeth. This is more commonly seen in children who swallow large amounts of fluoride-containing products.

Interactions with other drugs

Sodium fluoride  has minimal interactions with other drugs when used as an oral rinse. However, it is important to inform your dentist or healthcare professional about all the medications you are taking to ensure there are no potential interactions.
