Pocket irrigation can assist in treating the progression of periodontal disease. It aims to clean plaque from between the teeth (interdental) and under the gum line (subgingival) areas of the mouth in order to prevent the colonization of harmful oral bacteria. Pocket irrigation is also used to deliver antibacterial agents to the subgingival areas. It can be beneficial for interdental cleaning, the prevention of halitosis (bad breath), and subgingival cleaning. This helps keep the gum pockets cleaner and shallower, helping the gum tissue remain healthy. Pocket irrigation is generally performed in combination with other dental treatments, such as professional dental cleaning or pocket reduction surgery.
