Dental Did You Know: What's in your Toothpaste Part 2

Surfactants (detergents) such as sodium lauryl sulfate, ammonium lauryl sulfate and lauryl sarcosinate are used to produce a foam that helps clean teeth. The first two have significant antibacterial properties but can irritate oral tissues. To minimize this, lauryl sarcosinate is used in part or in whole as a replacement.
