Pulpectomy

A pulpectomy is a dental procedure that removes all pulp tissue from the crown and root canals of a tooth to treat infection and preserve the tooth.

Understanding 

Pulpectomy

A pulpectomy is a dental procedure used to treat severe infection or inflammation of the pulp inside a tooth. The pulp is the soft tissue that contains nerves and blood vessels within the tooth. When decay or injury spreads throughout the pulp chamber and root canals, the infected tissue must be removed to stop the infection.

During a pulpectomy, the dentist removes all pulp tissue from both the crown and the root canals of the tooth. The canals are then cleaned, disinfected, and filled with a special material designed to seal the space and help prevent reinfection. This procedure is most commonly performed on primary (baby) teeth to maintain the tooth in the mouth until it naturally falls out and is replaced by a permanent tooth.

Clinical Significance

Pulpectomy removes infected pulp tissue from the entire tooth and helps preserve the tooth structure. It prevents further spread of infection and maintains the function and spacing of the tooth.

How it Works

The dentist numbs the tooth and removes decayed tooth structure to access the pulp chamber. All pulp tissue from the crown and root canals is removed. The canals are cleaned and filled with a resorbable material, and the tooth is restored, often with a pediatric crown, to protect it.

Benefits

Removes infection from the tooth, preserves the natural primary tooth, maintains chewing function, supports proper spacing for permanent teeth, helps avoid early tooth extraction.

Risks or Considerations

Pulpectomy is used when infection has spread throughout the pulp tissue. If the tooth is severely damaged or the infection affects surrounding bone, extraction may be recommended instead. The treated tooth requires monitoring during routine dental visits.

Recovery & Aftercare

Recovery after pulpectomy is typically quick. Some children may experience mild tenderness or sensitivity for a short period. Aftercare includes maintaining good oral hygiene, avoiding hard foods temporarily, and attending follow up dental visits to monitor healing and tooth function.

Frequently Asked Questions

Q

What is the difference between a pulpotomy and a pulpectomy?

A pulpotomy removes only the infected pulp from the crown portion of the tooth while leaving the pulp inside the roots intact. A pulpectomy removes all pulp tissue from both the crown and the root canals of the tooth. Pulpectomy is used when infection has spread deeper into the roots, while pulpotomy is used when the infection is limited to the upper portion of the pulp.

Q

Is a pulpectomy the same as a root canal?

A pulpectomy is similar to a root canal procedure because both involve removing pulp tissue from inside the tooth and sealing the root canals. However, pulpectomy is most often performed on primary teeth in children and typically uses materials designed to dissolve as the tooth naturally falls out. Root canal treatment is more commonly performed on permanent teeth in adults.

Q

Does a pulpectomy hurt?

A pulpectomy is usually performed with local anesthesia to numb the tooth and surrounding tissues. This helps ensure that the procedure is comfortable. Children may feel pressure or vibration during treatment, but pain is generally minimized. Mild soreness after the procedure may occur for a short time but often improves quickly.

Q

Why is a crown placed after a pulpectomy?

After pulp therapy, the treated tooth may be weaker because part of the internal structure has been removed. A dental crown, often a stainless steel crown in children, is commonly placed to protect the tooth and restore its shape and function. The crown helps ensure the tooth remains stable until it naturally falls out.

Q

Is pulpectomy covered by dental insurance?

Many dental insurance plans provide coverage for pulpectomy procedures when they are necessary to treat infection in primary teeth. Coverage levels vary depending on the insurance policy and whether the procedure is classified as basic or major treatment. Reviewing your insurance benefits or speaking with your provider can help clarify expected coverage and costs.
