If you have been diagnosed with an infected tooth, you may need root canal therapy. If you have had an infected tooth, you will have constant pain, sensitivity to hot or cold foods, and swelling of the gums. In addition, the infection can spread to the jawbone, destroying the nerves and making your tooth useless. Root canal therapy can save your tooth from extraction. Here are some of the common reasons why you may need this procedure.

You may have experienced pain or sensitivity during the procedure. This is normal and can be managed with an over-the-counter pain reliever. After the procedure, you will be restricted to a soft diet and avoid eating hard or crunchy foods. Your dentist will likely place a crown to protect the tooth and keep it looking great. If you don't have a crown, you should try to chew with the opposite side of your mouth for several days.
