Root Canal Symptoms
The signs that mean a root canal may be necessary.

Certain serious problems with your teeth will mean a dentist recommends a root canal. Here's what kind of symptoms lead to that decision.
Root canal information
Unlike a cavity on the surface, a pulp or root infection occurs inside the tooth. Brushing or a filling won't stop it — the infection must be accessed and treated, or the infected root or pulp removed. Root canal therapy cuts into the tooth to reach the infected interior.
Persistent pain
Constant throbbing pain, even when you're not eating, usually means the problem is inside the tooth rather than on its surface.
Increased pain when chewing
Putting pressure on an infected root or pulp through chewing causes discomfort, sometimes limited to one tooth or spread across an area.
Temperature sensitivity
Pain from hot or cold that persists long after the drink is finished is a strong sign of an inner infection.
Tooth discoloration
If the uncomfortable tooth is also changing color, the infection is likely inside the tooth spreading outward to the surface.
Gum problems
Swollen, sensitive gums near the problem tooth — or a small pimple-like growth on the gums — can indicate the infection is affecting the gums.
