Clearing up root canal infection

After the diseased pulp is removed, the pulp chamber and root canals are flushed and cleaned. The root canals may be reshaped and made larger so it's easier to get into them for filling. The root canals are cleaned of all infection and dried before they are permanently filled. Medicine sometimes is put into the pulp chamber and root canals to clear any infection. If the infection has spread beyond the tooth, you may need a prescription for antibiotics.

After the root canal, you may have a short-term filling called a temporary filling. This is placed in the crown to protect the tooth and keep out food bits and saliva. Avoid biting or chewing on the tooth until it's been permanently treated and restored.
