Will my tooth be sensitive after a root canal?

Although the nerve and the blood supply have been removed from your tooth during the rooth canal, the tissues surrounding the tooth, like the periodontal ligaments, may have some residual inflammation. This inflammation can make the tooth sensitive to chewing/pressure even after you have removed the nerve during the root canal.

Most teeth that have undergone a root canal will not be sensitive at all. This is because all the nerve and pulp has been cleaned out from the inside. But on the outside, some of the tissues and nerves around the tooth may have been irritated, inflamed, and possibly even infected during the procedure. This is why antibiotics are usually given before root canals and other dental procedures. Even after the inflammation goes away, these surrounding tissues and nerves may be sensitive to pressure and touch. You will have some sort of feeling of the tooth, but abnormal sensitivity should not return.
