A microbial analysis (also called an oral bacteria or biofilm analysis) is actually a fast, simple and completely painless test to analyze the bacteria in the mouth and test for infection. This can identify gum-disease-causing bacteria and help the dentist and dental hygienist decide on the best treatments for eliminating them.
To do this, a dentist or hygienist swabs your teeth and tongue and sends these samples to a laboratory. These are examined for bacteria that cause oral infection. The lab sends a report to the dentist who uses this information to determine whether treatment is necessary, and if so, what type of treatment would work best.
A microbial analysis can help to prevent gum disease, treat gum disease and prevent it from recurring. Ask your doctor, dentist or dental hygienist whether you're at risk for gum disease and whether you should be tested.
