What is Root Canal Treatment?
Root canal treatment, also known as endodontic therapy, is a dental procedure used to treat infection at the center of a tooth, commonly called the pulp. It involves removing the infected or inflamed pulp tissue, cleaning and disinfecting the inside of the tooth, and sealing it to prevent future infections. Root canal therapy is typically recommended when the dental pulp becomes infected due to deep decay, repeated dental procedures on the same tooth, faulty crowns, or a crack or chip in the tooth.
This procedure is designed to save a tooth that might otherwise need to be extracted. A successful root canal helps maintain the tooth's natural appearance, ensures proper chewing function, and prevents the other teeth from drifting out of position. The treatment is typically performed under local anesthesia, ensuring a comfortable experience for the patient.
Contrary to popular belief, root canal treatment is not painful. With modern dental techniques and anesthesia, it is no more uncomfortable than having a routine filling. After the procedure, the tooth may be restored with a filling or crown for long-term function and protection.
Why is Root Canal Treatment Necessary?
The inside of a tooth contains nerves and blood vessels, collectively known as the pulp. When bacteria enter this space due to cavities or injury, the pulp can become infected or inflamed. If left untreated, the infection can lead to an abscess, which is a collection of pus that forms at the root of the tooth. This can cause pain, swelling, and even damage the surrounding bone.
Root canal treatment removes the infected pulp, cleans the canals, and seals them to prevent further issues. This preserves the tooth structure and prevents the need for extraction, which can be more invasive and expensive.
What Happens During the Procedure?
The root canal procedure is usually completed in one or two appointments depending on the tooth's condition. First, the dentist examines the tooth and takes an X-ray to determine the extent of the infection. Once the area is numbed, an opening is made in the tooth to access the pulp chamber. Using specialized instruments, the infected pulp is removed, and the root canals are cleaned and shaped.
After cleaning, the canals are filled with a biocompatible material called gutta-percha. The access hole is then sealed with a temporary or permanent filling. In most cases, a crown is placed on the tooth to restore its strength and function.
Aftercare for Root Canal Treatment
After the root canal procedure, patients may experience mild discomfort or sensitivity for a few days, which can be managed with over-the-counter pain relievers. It is essential to avoid chewing on the treated tooth until it has been fully restored with a permanent filling or crown. Practicing good oral hygiene, including brushing, flossing, and regular dental checkups, can help ensure long-term success.
Patients should contact their dentist if they notice prolonged pain, swelling, or any other unusual symptoms after treatment. Timely follow-up care helps ensure that the tooth heals properly and remains free of infection.
