Signs Your Toothache Could Need a Root Canal
Plenty of toothaches clear up with a simple filling, but some symptoms suggest the nerve is infected. Watch for pain that pulses and doesn’t fade, sensitivity to hot or cold drinks that hangs around after you’ve finished them, tenderness when you chew, a swollen gum or cheek, or a small bump on the gum that looks like a pimple. If the infection stays in place, it can form an abscess, damage the surrounding bone, and eventually cost you the tooth.
If any of this sounds familiar, our S Loop West team can examine the tooth and take X-rays today. Reserve your $89 emergency exam before the pain gets worse.
What Leads to an Infected Tooth Nerve
A tooth’s inner pulp can become infected in several ways:
- Decay that has worked its way through the enamel to the nerve
- A crack or break that leaves the pulp exposed
- Several dental procedures on the same tooth over time
- A filling or crown that has loosened, leaked, or failed
- A blow to the mouth or other injury
- A gum abscess or swelling around the tooth
- Ongoing, pulsing pain with no clear trigger
- Hot or cold sensitivity that doesn’t settle
