Do dentists need bacterial test answers to treat gingivitis?

Gingivitis: Usually no testing is needed. Current bacteria tests (culture) are unable to detect many of the bacteria involved in gingivitis. Visual diagnosis by an experienced provider is all that's needed.

Not Necessarily: But every practitioner will do what s/he thinks is best for your wellbeing. Start with a thorough professional cleaning and see how your gingiva responds. Don't forget good home care.
