Later stages of decay may lead to the need for a tooth extraction. It is also possible that a baby tooth or wisdom tooth may need to be removed to ensure room for other teeth in the mouth. Unlike a root canal, an extraction procedure aims to remove the tooth in its entirety. This is done by expanding the tooth socket and the separating the tooth from the ligament that keeps it in place. Extractions are often a last resort as teeth do not grow back. During this procedure, the doctor will make sure you are sedated and do not feel any pain. Any gaps left by the extraction may need to be replaced by an implant to ensure the proper placement of the teeth is not disturbed. However, this will be something your dentist will address with you based on your own needs.
