Understanding Root Canal Treatment: What You Need to Know

Root canal treatment is a popular dental procedure performed by dental professionals who aim to save severely damaged or decayed teeth. This treatment involves removing the damaged or infected tissue inside the tooth’s root canal and filling it with a biocompatible material. Root canal treatment is often a necessary process and helps save teeth that would otherwise need to be removed, preserving healthy teeth and ensuring that patients keep their beautiful smiles.

Understanding root canal treatment can help individuals make informed decisions about their dental health. In this article, we’ll cover everything you need to know.

When is a Root Canal Necessary?

A root canal is typically performed once the tooth pulp or nerve is damaged, inflamed, or infected. This can happen for a variety of reasons, including tooth decay, gum disease, or trauma to the tooth. The damaged tooth pulp can cause pain and sensitivity in the tooth, and if left untreated, it can cause an abscess, which can be extremely painful.

Common Symptoms

Here are some common symptoms that may indicate the need for a root canal treatment.

– Severe tooth pain when biting or chewing.
– Sensitivity to hot or cold temperatures that lingers.
– Discoloration or darkening of the tooth.
– Swollen or tender gums around the affected tooth.
– A small pimple or abscess on the gums.
– A broken or injured tooth.

How is a Root Canal Treatment Performed?

The root canal treatment is usually performed in two or three sessions, depending on the severity of the infection or damage. The procedure is performed under local anesthesia to help patients relax and reduce pain and discomfort.

The steps involved in a standard root canal treatment are as follows:

1. Preparing the tooth: The dentist will numb the tooth with local anesthesia, place a rubber dam around it to isolate it and keep it clean, and create an opening in the top of the tooth to access the root canal.

2. Cleaning and removing the diseased tissue: Once the canal is accessed, the dentist will use small instruments to remove the damaged pulp thoroughly. They will also clean the canal with a series of files to shape it to receive the filling. Once the pulp is removed, the canals and the chambers of the tooth are disinfected with a solution, and they may place medication in the tooth to help fight bacteria and reduce inflammation for several days, depending on the patient’s condition.

3. Filling the root canal: Once the tooth is disinfected and bacteria-free, the dentist will fill the canal with a rubber-like material called gutta-percha. It is placed in the canal with an adhesive material to seal off the canal from future infection. The dentist will then place a filling material, usually composite resin, in the tooth’s opening to fill it and restore the tooth’s natural shape.

4. Placing a dental crown: After the root canal therapy is complete, the tooth will need a crown or other type of restoration. The tooth is weakened after the procedure, so placing a crown will help protect the tooth from breaking or fracturing in the future.


Root canal therapy is generally pain-free, with only minor discomfort after the procedure. Patients may feel a bit sore or sensitive in the treated area for a few days. Over-the-counter painkillers and analgesics can help alleviate any discomfort.

Additionally, avoid chewing or putting any pressure on the treated tooth until it is restored with a dental crown.

Final Thoughts

Understanding the root canal treatment can eliminate any fear or confusion you may have about the procedure. Your dentist will work with you to ensure that you are comfortable throughout the process and adapted to your unique individual needs. Root canal treatment is a safe and effective way to save teeth and ensure that you maintain a healthy and beautiful smile.
