A dental curettage is a dental procedure to clean the dental pockets by removing chronically inflamed granulation tissue, dislodged calculus and tartar deposits from the root surfaces (under the gum). Bacterial colonies in calculus and tartar deposits might cause inflammation, infection, and bad odors. And that removal of the damaged tissue shall promote healing as well as the development of healthy tissue and reduction in periodontal pocket depth.

Curettage does not eliminate the causes of inflammation (e.g. bacterial plaque, calculus) so it should always be preceded by scaling and root planing. It is performed under local anesthetic to make the patient more comfortable, and the mouth is frequently flushed with a sterile solution to sweep out the debris.

Different types of dental curretages:

  • Closed curettage – A simple procedure during which the dentist or the dental hygienist cleans the surrounding tissue with special instruments.
  • Open curettage – The gum tissue is reflected away from the teeth to facilitate access for the removal of inflamed tissue surrounding the tooth and removal of tartar deposits on the root surface. Irregularities in the bone, caused by the progression of the periodontal disease, are corrected and finally the gums are repositioned back against the teeth.

What patients should know :

  • This treatment may require more than one visit
  • After this treatment you might need to be careful when cleaning the teeth above the gum-line, as the root planing should cause the gum pocket to shrink
  • This treatment is generally repeated on a regular basis.
  • Maintenance therapy might be recommended, periodically (3-4 times a year) for cleaning and periodontal assessment.

Although this treatment can help one to keep his/her mouth clean and healthy, one should not solely rely on this treatment alone. Maintaining a healthy mouth should be a daily core at home.
