Bacterial Testing

In severe cases of periodontal disease, when patients are affected by advanced premature bone loss, bacterial testing is performed to identify the most effective antibiotic(s) against your specific periodontal disease causing bacteria. The antibiotic of choice is used two to three times per year. Although oral antibiotics are not a cure for your periodontal disease, their use is an essential tool in helping to control your infection. Bacterial testing is usually completed during the first root planing appointment.


Sterile paper points are placed into five of the most severely pocketed areas. The points remain in the pocket for approximately fifteen seconds to absorb bacteria from the site. The points are placed into a sterile tube with growth medium, and sent overnight to the University of Southern California Department of Oral Microbiology. There the bacteria from the pockets are isolated, and then their susceptibility to four antibiotics tested.
