### How to Know If You Need a Root Canal A root canal is a dental procedure that cleans out decay from your tooth’s pulp and root. Here are some signs that you might need a root canal: 1. **Persistent Tooth Pain**: If you have ongoing tooth pain that doesn't go away, it could be a sign of an infection or nerve damage. 2. **Sensitivity to Hot and Cold**: If your tooth hurts when you eat or drink something hot or cold, and the pain lingers even after you stop, it might indicate an issue with the blood vessels and nerves in your tooth. 3. **Tooth Discoloration**: An infected tooth can become discolored, often turning a grayish-black color. 4. **Swollen Gums**: Swelling near the painful tooth can be a sign of an infection. You might also notice a small pimple on your gum that oozes pus. 5. **Pain When Touching the Tooth**: If your tooth is sensitive when you touch it or when you eat, it could indicate severe decay or nerve damage. 6. **Chipped or Cracked Tooth**: If you've chipped or cracked your tooth, bacteria can enter and cause an infection. 7. **Loose Tooth**: An infected tooth may feel looser than usual. If you notice any of these symptoms, see your dentist as soon as possible. Early diagnosis and treatment can lead to a better outcome. A root canal procedure is similar to getting a large filling and is usually not painful due to local anesthesia.
