When Tooth Pain Points to an Infected Nerve
Many toothaches improve on their own or can be treated with a simple filling. However, persistent or recurring pain may indicate that the nerve inside your tooth is inflamed or infected. Common warning signs include deep, throbbing pain, lingering sensitivity to hot or cold, discomfort when chewing, swollen gums or cheeks, a pimple-like bump on the gum, or a tooth that has become darker than the surrounding teeth.
An infected tooth nerve won't heal without proper treatment. If left untreated, the infection can develop into an abscess, damage the surrounding bone, and eventually lead to tooth loss. If you're experiencing these symptoms, schedule your $89 emergency exam to identify the problem and discuss your treatment options.
What Leads to an Emergency Root Canal
The nerve (dentists call it the pulp) is well protected until something breaks through the outer layers. These are the usual causes:
- Cavities that have been growing toward the center of the tooth
- A crack or fracture that exposes the pulp
- A tooth that has been drilled and filled several times over the years
- A filling or crown that has leaked or failed
- A hard blow to the mouth, even if the tooth didn’t break
- An abscess pushing up near the gumline
- Pain that wakes you up at night
