If dental decay or cavities are not treated soon enough, they can penetrate the protective layer of the tooth called the “enamel” and enter into the “pulp” of the tooth where the nerves are located. Since baby teeth (primary teeth) have a relatively large pulp chamber compared to the thickness of the enamel, it is common for cavities to reach the pulp. When this happens, the child will experience a toothache and the tooth may die if not treated soon enough.
During a pulpotomy, a hole is drilled in the tooth’s enamel and the infected pulp is removed. Once removed, a protective cap is placed over the hole to preserve the remaining pulp.
