Periodontitis is, along with caries, the most frequent infective disease today. Periodontitis causes bone resorption which surrounds the tooth causing it to lose support. Periodontitis therapy consists of removing the causative agent, i.e. specific bacteria from the surface of the tooth above and under the gum levels. These bacteria are protected within soft and firm tooth deposits, i.e. within the plaque and tartar and therefore need to be removed.

Supragingival deposits are usually removed with an ultrasound apparatus whose vibrations remove calculus without any pain. Subgingival deposits are removed by curettage using special instruments to grate the surface of the tooth. After the curettage, we polish the surface of the tooth to prevent subsequent deposits. During this therapy the patient’s cooperation and oral hygiene are essential.
