What is one of the primary uses of chlorhexidine in dental practice?

Chlorhexidine is a powerful antiseptic that is widely used in dental practice primarily for its ability to reduce plaque formation. It works by disrupting the cell membranes of bacteria, which helps inhibit their growth and reproduction in the oral cavity. This makes chlorhexidine particularly effective in managing and preventing periodontal disease, where plaque accumulation is a central issue. The use of chlorhexidine as a mouth rinse or in dental treatments allows for a significant reduction in the bacterial load, leading to healthier gums and a lower risk of cavities. This characteristic set it apart as a preventive measure, especially in patients who may be at higher risk for dental plaque accumulation, such as those with braces or other dental appliances.
