Your dentist is the best person to determine whether you need root canal therapy. However, there are some signs that indicate you might need this treatment, including:
- A tooth that is darker than the ones around it
- A pimple-like bump on the gums (known as an abscess)
- Increased dental sensitivity
- Visible damage to a tooth, such as chips or cracks
If you notice any such issues, you should schedule a dental appointment as soon as possible. Delaying treatment allows the problem an opportunity to get worse. The further it progresses, the more likely it becomes that root canal therapy would be unable to save the tooth. Removing the tooth altogether may become the only option.
