5 Signs You Need a Root Canal (Not Just a Filling)

<p>Not all tooth pain is created equal, and knowing the difference can save you a lot of time, money, and discomfort. A cavity that's caught early might need nothing more than a filling. But once decay or infection reaches the pulp — the soft tissue inside your tooth containing nerves and blood vessels — a filling alone won't solve the problem. Here are five signs that point toward needing a root canal rather than a simple filling.</p> <p>1. Sharp pain when biting down. If chewing on a specific tooth causes a sudden, sharp pain rather than a general ache, it often signals that the inner pulp is inflamed or infected.</p> <p>2. Lingering sensitivity to hot or cold. Brief sensitivity that fades in a few seconds is normal. Sensitivity that lingers for 30 seconds or more after the hot/cold trigger is gone is a warning sign.</p> <p>3. Swelling or a pimple-like bump on the gums. This can indicate an abscess — a pocket of infection at the root tip — which needs to be addressed, not just numbed with painkillers.</p> <p>4. A darkening tooth. A tooth that's turning grey or dark compared to its neighbors often means the internal pulp tissue has died.</p> <p>5. Pain that wakes you up at night. Persistent, throbbing pain that's worse when lying down (because blood flow to the head increases) is a classic sign of pulp inflammation that needs treatment, not just pain relief.</p> <p>If any of this sounds familiar, the important thing is not to wait. An infected tooth doesn't heal on its own, and delaying treatment usually means a more complex — and more expensive — procedure later. If you're experiencing any of these symptoms, it's worth getting it looked at promptly rather than hoping it resolves.</p>
