The treatment options for a bacterial oral infection differ depending upon the severity of the situation. If the infection is caught early - gingivitis - a thorough cleaning may help resolve the problem. If the infection has progressed to periodontitis then the first step is often a deep cleaning called scaling and root plan followed by a re-evaluation a few weeks later to assess the healing and future treatment needs. In either case, professional care must be augmented by good daily home care for the best results otherwise the condition is likely to return. In addition to tooth brushing, interdental cleaning is critical. There are many products that can accomplish this - including string floss, interdental brushes, wood or plastic toothpicks, and a water flosser. String floss requires a high level of competency for effectiveness so for many people, other products are a better choice. Of these products, the water flosser has been shown to reduce the type of bacteria associated with oral infections (gingivitis, periodontitis).
