If your child’s primary tooth has extensive decay, or has been damaged by trauma, action may be needed to restore the integrity of the tooth and prevent infection from spreading to surrounding teeth. After a set of X-rays are taken, your dentist will be able to assess the extent of the infection and may recommend a pulpotomy.
If the decay or trauma is close to or involves the nerve (or pulp) of the tooth, a pulpotomy may be recommended. When a cavity gets really deep, close to the pulp of a tooth, or even into the pulp, the pulpal tissue becomes irritated and inflamed. A pulpotomy is when the inflamed pulp chamber, usually on a baby molar, is removed. The dentist will remove all the infected tissue in the pulp of the crown only, leaving the living tooth root intact. After a pulpotomy on a baby molar, the empty space will be filled with MTA (a bioactive material that seals the chamber and promotes healing) and a stainless steel crown will be placed to restore the tooth.
