Root Canal Therapy


Root Canal Therapy

Root canal treatment, also known as endodontic treatment is a procedure done to repair and save a badly decayed or infected tooth instead of removing it. The term "root canal" is derived from the cleaning of the canals present in a tooth's root. In the past, root canal procedures were often painful. But nowadays, with modern equipment and advanced technology most patients have no pain while undergoing root canal treatments.

Why you may need a root canal

The root canals of teeth have a soft core called pulp. Pulp consists of blood vessels and nerves, which provide the teeth with nutrients and oxygen. When a tooth has a deep cavity, bacteria can enter the cavity and infect the pulp. If left untreated, bacteria and decaying material can cause a severe infection, which progresses to the root canals, where the nerves and blood vessels get infected and inflamed. The swollen pulp tissue dies and the pulp chamber is filled with infected material and pus. This causes swelling, pain and may damage the neighboring bone structure, which results in a tooth abscess. Hence the need for root canal treatment to eliminate the infected pulp. The removed pulp is replaced with a filling.

Root canal procedure

The root canal treatment involves cleaning and sanitizing the root canals plus removing the infected pulp tissue. The procedure is carried out by a dentist over two or more visits depending on the situation. If the tooth has an active infection, antibiotics are prescribed for 3 to 5 days to reduce the pain and infection. Local anesthesia is given before the procedure so that the patient is comfortable. First of all, a rubber dam is positioned on the infected tooth to ensure the tooth is dry during the procedure and to prevent contamination of the canals. Once the upper layer of the tooth is opened with the help of a dental drill, the dentist will access the infected pulp and take it out.
The next part is to clean the inner of the tooth using a set of small files. With the help of these tooth files, the space left after the pulp is removed is cleaned and enlarged. This step needs many hours to complete and might be carried out in multiple visits. It also depends on the infected tooth. Molars and premolars, which have two or three roots with multiple canals, require a longer period to treat. During the first visit, the tooth is carefully cleaned and a temporary filling is done.
During the second visit, the temporary filling is detached, the canal is filled, and the tooth is sealed with a crown. The crown protects the treated tooth from fracturing.

After care

Avoid eating hard foods until the treatment is complete. Maintain good oral hygiene by regular brushing and flossing. Limit your intake of sugar and sodas. With proper care, the root-filled tooth can last a lifetime.
