Number one goal is to always preserve your child’s natural teeth, but sometimes one can become so damaged or infected that the best solution is to simply extract it. 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. Some extractions are needed for orthodontic reasons to help facilitate tooth alignment when crowded teeth are present. Primary teeth are essential in maintaining the correct spacing in your child’s jaw for the permanent teeth.
