Why Chlorhexidine is used in tootpast and mouthwashes?

Basicaly chlorhexidine is an

antibacterial used as a disinfectant and other applications. It is

also used in disinfectants (disinfection of the skin and hands).

Chlorhexidine is often used as an active ingredient in mouthwash

designed to reduce dental plaque and oral bacteria.

Chlorhexidine lasts longer in the

mouth than other mouthwashes, which is partly why it is to be

preferred over other treatments for gums. So that is the reason for

chlorhexidine to be used in tootpast and mouthwash.
