We have new patients call us time to time and say “My Tooth Cracked After a Root Canal” If your tooth cracked following a root canal, chances are you were suffering from a condition known as cracked tooth syndrome. Unlike teeth with fractures that are clearly noticeable, the fractures in cracked tooth syndrome are too small for your dentist to spot, even in dental x-rays. The crack may even be present below the gum line. Additionally, teeth that have undergone root canal treatment are weaker than your other teeth, making them more inclined to crack.


The symptoms of cracked tooth syndrome can come and go. You may experience pain or a feeling of pressure when you bite down in certain ways, or when you eat specific foods. If left untreated, the tooth may eventually become loose.

If your tooth has an obvious crack, you will likely be able to see or feel the crack when looking in a mirror or pressing with your tongue. If you can see the crack, it is important that you visit our office as soon as possible in order to prevent further damage and save the tooth.


Cracked tooth syndrome can be difficult to diagnose. We will perform a full examination of the tooth in question. Using a dental explorer, your dentist will carefully feel for cracks and irregularities, especially around the gum line. They may also take additional dental x-rays. A special dye and fiber optic light can also be used to check for tiny cracks in order to better inspect the tooth.

In the case of an obvious crack, we may be able to see it with their eyes, or on your dental x-rays. These cracks are more easily diagnosed and treatment will be fairly straightforward.


If the crack is obvious, we will usually restore the tooth using a dental crown. This will help to protect the tooth from further damage. If the crack is very severe or extensive, a tooth extraction may be necessary. If this occurs, your tooth will be replaced using a dental implant, or a dental bridge or partial denture in order to prevent any gum or bone loss from occurring, as well as to protect the surrounding teeth.
