12.3.4 Mouthwashes, Gargles, and Dentifrices


First choice: CHLORHEXIDINE GLUCONATE 0.2% MOUTHWASH
 

Chlorhexidine gluconate (0.2% mouthwash) has a specific effect in inhibiting the formation of plaque on teeth. It may be useful as an adjunct to other oral hygiene measures in cases of oral infection or when patients cannot clean their teeth in the normal way. It may cause temporary brown staining of the teeth. If chlorhexidine mouthwash is irritant it can be diluted up to 50:50 with water.
It should not be used at the same time as nystatin suspension due to incompatibility and loss of antifungal effect, allow minimum of one hour between administrations. 
It may be incompatible with some ingredients in toothpaste, leave at least 30 minutes between using mouthwash and toothpaste.

Hydrogen peroxide (mouthwash) is prepared immediately before use by diluting 15mL of 20-volume (6%) hydrogen peroxide in half a tumblerful of warm water.  It is used as a deodorising and cleansing mouthwash with mildly antibacterial properties.  It effervesces on contact with debris in the mouth, which enhances its mechanical cleansing activity.
