Extractions are done only as a last resort in the case of severe tooth decay. If a primary molar is removed prematurely, a space maintainer will be placed. Primary teeth are essential in maintaining the natural spacing in your child’s jaw for the permanent teeth. Extractions are needed for grossly decayed teeth, infections, problems with wisdom teeth and orthodontic reasons to help facilitate tooth alignment when crowded teeth are present.
When it is determined that a tooth needs to be removed, the doctor may extract the tooth during a regular checkup or may request another visit for this procedure. The root of each tooth is sheathed within the jawbone in a tooth socket, and the tooth is held in that socket by a ligament. In order to extract a tooth, the dentist must expand the socket and separate the tooth from the ligament holding it in place.
