Is Your Toothache a Root Canal Problem?
Plenty of toothaches have simpler causes, but some symptoms point to an infected nerve. Watch for deep, pulsing pain that won’t ease, sensitivity to hot or cold that lingers long after the drink is gone, swollen gums or cheeks, a small pimple-like bump on the gum, or pain when you bite or press on the tooth. An untreated infection can form an abscess, damage the bone around the tooth, and eventually cost you the tooth.
Our Southside Place dentists can find the source of your pain and treat it quickly. Your $89 emergency exam shows what’s going on inside the tooth and what it will take to save it.
What Causes a Tooth Nerve to Become Infected
Nerve infections develop in several ways. These are the most common:
- Decay that has worked its way deep enough to reach the nerve
- A cracked or fractured tooth that exposes the pulp inside
- A tooth that has needed repeated dental work
- A filling or crown that has worn out or let bacteria seep underneath
- A blow or injury to the tooth
- An abscess, or swelling along the gumline
- Constant, throbbing pain with no clear trigger
- Hot or cold sensitivity that doesn’t fade
