How do you know when you need a root canal? Sometimes, the pain you feel makes it an obvious need. If you feel constant and severe pain and pressure in your mouth, or noticeable swelling and extreme sensitivity in your gums, then it’s clear you need an evaluation and treatment as soon as possible. Another symptom of pulp tissue damage is sharp pain when you bite down on food. Lingering pain after eating foods that are really hot or really cold is also an indication of potential trouble. If any of these symptoms arise, you need to have an examination as soon as possible.
