Why Does My Tooth Hurt?

Tooth pain can come out of nowhere—and it’s your body’s way of telling you something’s off.

Tooth pain can show up suddenly or build over time, and it’s often your body’s way of signaling that something isn’t right. Common causes include cavities, gum irritation, cracked teeth, or exposed nerves that react to hot, cold, or sweet foods.

While some discomfort may fade on its own, pain that lingers, worsens, or comes with swelling can indicate a deeper issue. Addressing tooth pain early helps prevent infections and more complex dental problems down the road.
