SnF2 and NaF
Stannous fluoride is better, as it can make tooth enamel, more resistant towards bacteria.
Generally not. Stannous fluoride definitely does but it's removable and just surface stain.
Sodium Fluoride, the active ingredient in most toothpastes, is only approved by the FDA for cavity prevention. Stannous Fluoride (SnF2) is an antibacterial ingredient that kills plaque bacteria. It helps keep plaque from coming back by inhibiting plaque re-growth. SnF2 also protects against painful sensitivity by blocking exposed dentinal tubules, the source of sensitivity.
Some chemicals added to prevent tooth decay are: sodium fluoride, potassium fluoride, stannous fluoride, sodium fluoride phosphate, etc.
Fluoride is added to drinking water to prevent tooth decay
Fluorides of sodium and potassium, stannous fluoride, etc.
The element fluorine, as stannous fluoride or as sodium fluoride, is added to toothpaste (and some drinking water) to aid in the strengthening of tooth enamel.
Toothpaste contains 20 - 42% water. Around half of the compounds are abrasives like alum1inum hydroxide, calcium carbonate, calcium hydrogen phosphates, silica's, zeolites, and hydroxyapatite. It also contains fluoride in various forms like sodium fluoride.
They have Stannous Fluoride, Sodium Hexametaphosphate. Not all are the same, some may have different contents than some others. Teeth.
Floride is added to toothpaste to strengthen the enamel of the tooth. This helps prevent tooth decay, particularly in children.
It is the element Fluorine. It is added as Fluoride.
