How does sodium fluoride work?
Fluoride acts directly on erupted teeth. It makes the tooth surface more resistant to mineral loss and supports remineralisation of early damage in enamel and exposed dentine. Systemic exposure should be minimal when the toothpaste is spat out rather than swallowed.
How to take sodium fluoride
Use only as a toothpaste and follow the product label or dental professional's instructions.
Use it in place of ordinary toothpaste when instructed.
Brush carefully across all tooth surfaces, including the gum line and exposed roots.
Spit out after brushing; do not swallow.
Do not rinse immediately, because this removes fluoride remaining on the teeth.
sodium fluoride side effects
Get urgent medical advice
- Rare hypersensitivity reactions; obtain urgent help if accompanied by facial or throat swelling, breathing difficulty, collapse or widespread severe symptoms.
- Swallowing a large amount may cause nausea, vomiting or diarrhoea; severe poisoning can cause muscle spasms, seizures or cardiovascular problems.
sodium fluoride in pregnancy
The selected product information states that it can be used during pregnancy. It is intended to act locally and should be spat out; discuss substantial or repeated accidental swallowing with a healthcare professional.
sodium fluoride while breastfeeding
The selected product information states that it can be used while breastfeeding. Use it only in the mouth, spit it out and keep the tube away from young children.
sodium fluoride interactions
Formal interaction studies have not been performed. Total fluoride exposure and the timing of other dental products are the main practical considerations.
Fluoride mouthwashes
Using mouthwash immediately after brushing removes concentrated fluoride from the teeth; use it at another time if recommended.
Other fluoride-containing products
Consider all fluoride sources where swallowing is possible, because repeated excessive ingestion increases toxicity risk.
