Routine dental cleaning is a preventive measure to ensure you have healthy oral conditions. During routine cleanings, plaque and tartar are removed from above your gum lines. However, chances are there that some plaque might get accumulated below your gums and form the building ground for bacteria. It can give rise to periodontal diseases, which, in turn, can affect your overall dental conditions. Periodontal maintenance cleanings, also known as deep cleaning, clean below your gums and eradicates all bacteria building plaque and tartar.
