Pain While Biting or Chewing Discomfort when eating or biting can indicate nerve involvement within the tooth, making root canal treatment necessary.

Tooth Discolouration A darkened or discoloured tooth often shows internal damage and may require dental root canal treatment to save the tooth.

Swelling and Tenderness Inflamed or swollen gums around the affected tooth may signal an underlying infection inside the root canal.

Increased Sensitivity Prolonged sensitivity to hot or cold foods even after the temperature stimulus is removed is a common sign of pulp irritation.

Persistent and Intense Pain Constant toothache or sharp pain while chewing or applying pressure can indicate a deep infection requiring immediate root canal treatment for pain management.
