Root canal therapy involves the removal of the pulp of a tooth. This procedure is necessary when the pulp, which contains nerves and blood vessels, becomes infected or inflamed, often due to deep decay or trauma to the tooth. During root canal therapy, the dentist drills into the tooth to access the pulp chamber and root canals, removes the infected or necrotic pulp tissue, cleans and disinfects the interior of the tooth, and finally seals it to prevent future infection.

Dental cleaning typically refers to the process of professionally cleaning the surfaces of the teeth to remove plaque and tartar but does not involve any surgical or invasive procedures. Dental crown placement is a restorative procedure where a crown is placed over a tooth that has been extensively damaged but does not involve the removal of pulp. Tooth extraction, on the other hand, refers to the complete removal of a tooth from its socket in the bone, which may sometimes be performed in conjunction with root canal therapy if the tooth is beyond saving. However, tooth extraction does not specifically involve the removal of the pulp since the tooth is completely removed instead.
