Root canal treatment for inflammation can always be done without extracting the tooth. Whether or not the tooth is extracted is determined by whether or not the tooth has any value. If the tooth is a source of infection or is severely loose, extraction is recommended. Root canal treatment for inflammation involves removing the infected nerve and sealing the root canal. After the inflammation in the root canal is completely controlled, the canal is filled and finally restored with a crown. If the tooth has retained value, extraction is not necessary because the retained tooth can continue to perform its function after root canal treatment. If the inflammation still cannot be controlled after root canal treatment or even has expanded, apical surgery or direct extraction can be performed according to the specific situation. At the same time, daily attention should be paid to maintaining oral hygiene, rinse your mouth in time after meals, and brush your teeth regularly every morning and evening. It is recommended that any abnormalities in the teeth should be dealt with in a timely manner in a regular dental hospital to avoid delays.
