Sodium fluoride, toothpaste ingredient

The most recognized toothpaste ingredient is probably the class of compounds known as fluorides. Stannous fluoride was the first to be used in toothpaste because, unlike sodium fluoride, it did not lose its effectiveness when combined with the abrasive most common at the time, calcium phosphate. Later, sodium mono-fluorophosphate came into popular use because it too could be used with the common abrasives.

Fluorine is a yellowish gas and is the most reactive halogen. Its most recognized use is as sodium fluoride (NaF), which is used for tooth decay prevention in toothpastes and municipal water supplies. Chlorine is a yellow-green gas, is extremely poisonous, and has a stifling, pungent odor—the odor of common household bleach. While it is indeed useful as a bleach, the primary ingredient in household bleach is sodium hypochlorite (NaClO), an important compound of chlorine. 

Tin (Sn) Tin is a silvery white metal. Solder is an alloy of tin and lead and is used in electrical connections. Stannous fluoride (SnF2) was once a common ingredient in toothpaste, but has largely been replaced by sodium monofluo-rophosphate.
