With an inadequate oral hygiene, the residue and the colony of bacteria colonizing the areas hard to clean will turn into plaques, leading to gum inflammation, or bleeding, swollen gums and periodontal diseases. Dental residues, plaque and bacteria penetrate deep, causing the bone to decay. In the absence of an intervention, the tooth will loosen and fall out. To stop this damaging process, the gums around the tooth, the bone and its surface under the gum shall be cleaned off. This intervention is called a curette. Depending on the severity and depth of the disease, a closed or an open curette shall be made.
