  • The abcess under the crowned tooth develops because of various reasons like developing some gum disease or when the gap develops between the tooth and the crown. If proper hygeine is not maintained and the gum infection is there ,it can cause the abcessed tooth. some time the abcess is formed if the wearing off of the crown takes place and the hole develops which causes the seepage and hence the infection of the tooth. You have to visit the dentist who will do the clinical examination and take the X-ray to find out the cause of the infection. If the tooth can be saved and the prognosis is good then the dentist will remove the crown and do the re root canal treatment of the tooth.
