Bacterial plaque produces irritants, which cause gingivitis and periodontitis, ultimately leading to loss of teeth. Chemical control of plaque is achieved effectively with Hexidine. As an antimicrobial, Hexidine prevents secondary infections arising out of poor oral hygiene. It is particularly useful in plaque control for: Bed-ridden patients following surgery or in the ICU. Respiratory tract infections such as pharyngitis, tonsillitis, post-tonsillectomy surgery, preventing complications of pregnancy gingivitis and bacterial endocarditis. Preventing dental caries.
