What causes root canal infection

An infection in the root can start many different ways. Usually, though it is due to deep decay in a tooth. The decay has gotten to the nerve and caused the infection.

But sometimes, nerves just go bad and get infected. It is unusual to be given antibiotics at the end of an RCT because there should be no further infection present.

How to treat a root canal infection? Are there hidden dangers to getting a root canal? Still, they can happen. Root canal infections are very rare.

After the initial root canal, the pain should subside after a few days. If it continues past day four or five, it could be a sign that the infection is still present. Likewise, if the tooth is feeling better, but then suddenly starts to feel worse, there is a good chance that bacteria has won again.

This patient presented with this infected root canal draining pus out to the gums, as shown in the featured picture above. There was some discomfort but no significant pain. A great example is my husband Manuel. He lived with an infected root canal for over years.

A root canal is a dental procedure performed to help save a natural tooth that has become diseased or infected. During this procedure, the pulp of the tooth, which contains nerves and blood vessels, is removed. The inside of the tooth is cleaned and sealed. The root tip may be sensitive and as a result become susceptible to the formation of an infection from another source within your mouth.

Some infections, which could be caused by an abscess, form before the root canal is performe while others experience an infection after the root canal procedure has been completed. During root canal treatment, your dentist cleans up the canals making use of special instruments called files. Irritated or infected tissue is removed. An apicoectomy may be required when an infection develops or will not go away after root canal treatment or retreatment. Like any other infection , a root canal infection can spread to surrounding tissue in the mouth, including other teeth, gums, and tissue in the cheeks and face.

You may be worried about what caused the infection , and you may also be wondering if root canal infections spread.

In addition to an abscess, an infection in the root canal of a tooth can cause: Swelling that may spread to other areas of the face, neck, or head. The term root canal is colloquially used to denote the central space of a tooth, where blood vessels and nerves are present. Infection to this cavity is not an unusual case.

The bone around the tooth looks fairly normal, certainly within normal limits for a root canal tooth, as shown with the arrow. Most dentists would say that this tooth looks to be healthy, as there is no evidence of infection and the canals look well filled. Likewise, if the root canal filling is extruded beyond the tip of the tooth root , an subsequent infection may develop. Endodontic treatment is necessary when the pulp, the soft tissue inside the root canal , becomes inflamed or infected. The inflammation or infection can have a variety of causes : deep decay repeated dental procedures on the tooth or a crack or chip in the tooth.

This is the main reason patients need root canals. If a cavity becomes large enough, it can enter your pulp chamber or nerve. What causes a root canal ? If bacteria enters this chamber, it causes pain, and sometimes, an infection.
