Root canal treatment takes about half a month, with a total of three sessions, each about a week apart. The first treatment is to seal the root canal with a deactivating agent to kill the pulp by dehydration; the second treatment is to prepare the root canal to remove the necrotic pulp completely and clean the root canal thoroughly with a large amount of solution to prepare the root canal in a standard form for the next root canal filling; the third treatment is the root canal filling treatment, which is to test the tip with dental cement to see if the cement matches the root canal form and reaches the apical area. The third treatment is the root canal filling treatment, in which a test tip is made with a dental cement to see if it matches the shape of the root canal and the extent of the area where it reaches the root tip, followed by the filling with a hot cement to completely seal the root canal to avoid any subsequent bacterial attack, which is all the steps of the root canal treatment.
