The periodontal disease (PD) is described as a set of inflammatory and infectious process that attacks periodontal tissue of multifactorial etiology, localized and considered by the World Health Organization (WHO) as one of the two main disease in odontology. Unchained and perpetuated for Gram negative anaerobic bacteria, whose anti-septic and antibiotic resistance demand new methods for clinical treatment (scaling and root planing). In this approach, the use of natural products could be promising. The aim of this work was a literature review about the use of natural products in the chemical control of the growth of subgingival dental biofilm. The work showed that antimicrobial natural agents can be useful as adjunct to mechanical therapy and deserve a special attention, since Brazil hold a rich biodiversity and because scientific works indicate an antimicrobial activity in vitro in assays using natural products. Thus, methods of treatment of periodontal diseases, efficient and accessible to Brazilian population could change the actual scenery of odontology in Brazil.
