If the infection involves tissue in both the tooth crown and the tooth root, a pulpectomy may be the best option. In a pulpectomy, the entire pulp material is removed from both the crown and the roots. After numbing your child’s tooth, the dentist will remove the pulp and nerve tissue from the crown and from the canals of the roots. Then, the pulp chamber and root canals will be thoroughly cleaned and disinfected. Next, the dentist will fill the tooth and tooth roots with a dental cement, and finish with a stainless steel crown.
