It is possible to extract the tooth without root canal treatment, but if the tooth can be preserved as much as possible, root canal treatment can be chosen for pulpitis and apical periodontitis. If the affected tooth has too many defects, more serious loosening, large cracks in the tooth, etc., it is impossible to retain the affected tooth, and the tooth needs to be extracted in time. In this case, the tooth can be extracted directly without the need for root canal treatment. However, if there is a chance to keep the tooth, try to treat it as much as possible, such as endodontitis and periapical periodontitis should choose root canal treatment. This is because tooth extraction can lead to tooth loss and affect chewing function. It is important to note that brushing and rinsing are prohibited within 24 hours after tooth extraction, so as not to wash or brush away the blood clots from the wound, which can lead to wound infection and the formation of dry socket. It is also important to note that you can eat only after two hours of tooth extraction, but you cannot use the affected side to chew food. It is recommended that patients with dental problems can consult a doctor for diagnosis and wait for the doctor to determine whether the tooth is extracted or not before proceeding to deal with it, so as not to cause serious consequences.
