There can be more than one reason why an individual requires a dental extraction. It can be tooth decay, dental trauma or periodontal disease that causes immense pain. In some cases, a damaged tooth may also have to be removed. Dentists, generally, offer two types of dental extractions. These include simple and surgical. In the simple extraction process, a set of easily accessible dental tools are used to remove the tooth. The dentist uses local anaesthesia for extraction purposes.
