How does sodium monofluorophosphate prevent cavities?
Sodium monofluorophosphate releases fluoride ions that are absorbed by tooth enamel. This process, called remineralization, strengthens the enamel and makes it more resistant to the acids produced by plaque bacteria, thus preventing cavities.
Is sodium monofluorophosphate safe for children?
Yes, it is safe for children when used as directed in toothpaste. However, children should be supervised to ensure they do not swallow large amounts, as excessive fluoride intake during tooth development can lead to fluorosis.
