Root canal treatment is a dental procedure that is performed to save a tooth from extraction. It involves removing the infected or damaged pulp from inside the tooth and then sealing it to prevent further infection. While root canals are a common dental procedure, they are often associated with pain and discomfort. 

1. Persistent Toothache

One of the most common signs that you may need a root canal treatment and surgery is a persistent toothache. This toothache may range from mild to severe and can be throbbing or constant. The pain may increase when you bite down or apply pressure to the affected tooth.

2. Sensitivity to Hot and Cold

If you experience sensitivity to hot and cold temperatures that lingers even after the hot or cold stimulus is removed, it could be a sign that you need a root canal. This sensitivity occurs due to the inflammation of the pulp inside the tooth, which contains nerves and blood vessels. 

3. Swelling and Tenderness of Gums

Another indication that you may need a root canal is swelling and tenderness of the gums around the affected tooth. The infection or inflammation in the pulp can spread to the surrounding tissues, leading to gum swelling and tenderness. 

4. Discoloration of the Tooth

If you notice that one of your teeth has become discolored or darkened, it could be a sign that you need a root canal. Discoloration occurs when the pulp inside the tooth becomes damaged or infected, causing the tooth to lose its natural color. This discoloration may be subtle at first but can progress over time. If you notice any changes in the color of your tooth, it is important to consult a dentist for an evaluation.

Conclusion

Root canals are often necessary to save a tooth from extraction and alleviate pain and discomfort. If you experience persistent toothache, sensitivity to hot and cold, swelling and tenderness of gums, discoloration of a tooth, or a persistent pimple on the gum, it is important to seek dental attention as these are signs that you may need a root canal. Remember, early detection and treatment can help prevent further complications and save your tooth.
