Inside of every baby (deciduous) and permanent adult tooth is a central chamber that contains connective tissue, a nerve supply, and blood vessels. Collectively these core tissues, known as the dental pulp, help the tooth to grow and mature before it emerges into the mouth. Once your tooth is in place, the dental pulp provides nourishment, keeps the tooth vital, and alerts you of problems. Unfortunately, cavities and dental trauma can damage the dental pulp inside of a tooth. When one of these factors has involved the dental pulp of a primary or deciduous tooth and there is no evidence of an infection at the root of the tooth, a procedure known as a pulpotomy may be performed. The purpose of a pulpotomy on a “baby” tooth is to maintain it until its permanent successor tooth erupts. This is because deciduous teeth that are lost prematurely can result in space loss for the permanent tooth and other consequences. During a pulpotomy procedure, the exposed or affected pulp tissue within the crown of the deciduous tooth (the visible portion of the tooth) is carefully removed and a special medication to disinfect the area and calm the remaining nerve tissue is placed. Once the procedure is complete, the baby tooth is then restored. Depending on the amount of tooth structure remaining and how much time is left before the baby tooth is to fall out, the type of restoration is selected. Typically, the most effective restoration to seal the tooth and restore function, is a stainless steel crown.
