What concentration of chlorhexidine is typically used in mouth rinses?

Chlorhexidine is widely used in dental practices, particularly in the form of mouth rinses, for its antiseptic properties that help reduce plaque and gingivitis. The most commonly used concentration in mouth rinses is 0.2%. This concentration provides an effective balance between antimicrobial action and safety for daily use, allowing patients to benefit from the rinse without experiencing significant side effects. Higher concentrations, such as 1.0% or above, may lead to increased staining of teeth and altered taste sensation, making them less suitable for routine oral hygiene. Therefore, a concentration of 0.2% is favored in mouth rinses for its efficacy and tolerability among patients.
