Chemical Agents
The reduction of mouth odor is attained by the use of chemical agents such as lozenges and dentifrices. Mouthwash reduces the bacteria load in the mouth and on the back of the tongue, most commonly mouthwash with chlorhexidine and zinc lactate. People tend to discontinue the long term use of mouthwash with Chlorhexidine because it gives a burning sensation around the mouth due to its antibacterial properties. Avoid mouthwash with alcohol as this can induce dryness and worsen the case. The considerate time to use mouthwash is before you sleep because the residual of the mouth wash will remain longer in the mouth reducing the accumulation of oral malodor bacteria while you sleep.
