Previous Next 4 of 7 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 enlarged to allow better access for filling. Before permanently filling the root canals, they are cleaned of all infection and dried. Medication is sometimes put into the pulp chamber and root canals to clear any infection. If infection has spread beyond the tooth, you may need a prescription for antibiotics. After root canal therapy, a temporary filling is placed in the crown to protect the tooth and keep out debris and saliva. Avoid biting or chewing on the tooth until it's been permanently treated and restored.
