What is the concentration of Chlorhexidine mouth wash commonly used in practice?

Chlorhexidine mouthwash is commonly used in dental practice primarily for its antimicrobial properties, particularly in the management of gingivitis and other oral infections. The most widely used concentration of Chlorhexidine for therapeutic purposes is 0.12%. This concentration strikes an effective balance between antibacterial efficacy and safety for short-term use in the oral cavity, minimizing potential side effects such as staining of teeth and alteration of taste perception.

Lower concentrations, like 0.02%, may not provide sufficient antibacterial action for therapeutic goals, especially in managing more severe inflammatory conditions. Conversely, higher concentrations such as 0.5% and 1% may pose a higher risk of adverse effects without providing significant additional benefits. Thus, the selection of 0.12% as a standard concentration in clinical settings is based on extensive research demonstrating its effectiveness and safety for common dental applications.
