Toothpaste: Triclosan

 

Triclosan is an anti-bacterial agent that has shown effectiveness against plaque, gum disease, and bad breath.

Plaque is a sticky biofilm made by bacteria.  Triclosan helps kill these little bugs.

Gum disease (Gingivitis and/or Periodontitis) is caused by another type of bacteria.  Triclosan can help kill this kind too.

Bad breath (malodor) is also caused by bacteria, and yep.  Triclosan can help.

Some controversy exist about the safety of Triclosan.  Colgate Total still uses a Triclosan formulation.  Crest sold in the United States does not, although a Canadian formula of theirs does.
