Once a root canal treatment is performed, the recipient must have a crown placed over the tooth to protect it. The cost of the treatment and the crown may be expensive. However, replacing an extracted tooth with a fixed bridge, a removable partial...
denture, or an implant to maintain the space and restore the chewing function is typically even more expensive.
During the time when antibiotics are being used, care should be taken to avoid using the tooth to chew food. The tooth has been structurally weakened and may break, or there is a possibility of the interior of the tooth becoming reinfected.
If the tooth feels sensitive following the procedure, a standard over-the-counter pain medication such as ibuprofen or naproxen may be taken. This sensitivity will fade after a few days. In most cases the patient can resume regular activity the following day.

This narrated animation shows how root canal surgery can save a natural tooth from destruction from advanced tooth decay. A cut away view of the tooth is shown along with the steps required to replace the diseased core of the tooth. In this version of a root canal, an artifical crown is placed, commonly referred to as a dental cap.
During a root canal, the diseased pulp of a tooth (A), is removed (B). The remaining empty tooth is filled and sealed with a filling or crown. (Illustration by GGS Inc.)

Other Information
In the situation that a tooth is considered so threatened (because of decay, cracking, etc.) that future infection is considered likely or inevitable, a pulpectomy, removal of the pulp tissue, is advisable to prevent such infection. Usually, some inflammation and/or infection is already present within or below the tooth. To cure the infection and save the tooth, the dentist drills into the pulp chamber and removes the infected pulp by scraping it out of the root canals. Once this is done, the dentist fills the cavity with an inert material and seals up the opening. This procedure is known as root canal therapy. If enough of the tooth has been damaged, or removed as a result of the treatment, a crown may be required.
