How can you tell if a tooth has gone bad under crown that root canal?

Signs of a Bad Tooth Under a Crown with a Root Canal:

1. Pain or Temperature Sensitivity:

- Sensitivity to hot or cold temperatures that lasts longer than a few seconds might indicate a problem.

2. Swelling or Tenderness:

- Swollen or tender gums near the crowned tooth can signal an infection or inflammation beneath.

3. Recurring Infection or Abscess:

- Repeated gum infections or the formation of an abscess around the crown are strong indicators of underlying issues.

4. Visible Cracks or Chips:

- Cracks, chips, or breakage of the crown can allow bacteria to infiltrate and cause decay under the crown.

5. Persistent Bad Taste or Odor:

- A foul taste or odor coming from the affected area can be a sign of underlying decay.

6. Discomfort When Biting:

- Unexplained discomfort or pain when biting or chewing can be a symptom of a problem beneath the crown.

7. Loose Crown:

- A crown that feels loose or wiggly can be a result of underlying structural issues.

8. Visible Decay or Leakage:

- If decay or leakage is visible near the crown's margin (where it meets the gum), there might be a problem beneath.

9. Gum Recession:

- Receding gums exposing more of the tooth's root might be a sign of bone loss and underlying problems.

10. Lymph Node Tenderness:

- Swollen or tender lymph nodes in the neck or face can indicate an infection spreading from the affected tooth.

11. Discoloration or Darkening:

- Crown darkening or discoloration different from the surrounding teeth might be a sign of underlying issues.

12. General Discomfort or Pain:

- Unexplained discomfort or persistent pain in the area of the crowned tooth warrants further evaluation.

If you experience any of these signs or suspect a problem with a crowned tooth, it's important to visit your dentist for a thorough examination and appropriate treatment.
