Pain After a Big Cavity Filling? Signs You May Need a Root Canal
May 20, 2025
Getting a cavity removed is never an easy affair. Besides the discomfort of staying still for a long period of time, if the tooth decay is close to your tooth’s nerve, even with anesthesia, the pain can be noticeable. However, if it continues months after the cavity removal, it could be a sign that you need to visit an emergency dentist in Charleston for a root canal.
When decay reaches the pulp chamber, your tooth’s nerves can be infected, causing discomfort and pain. Here are some signs you need endodontics to remove all that’s infected and protect your tooth!
5 Signs That Indicate You Need a Root Canal
1. Lingering Sensitivity to Hot or Cold
Sensitivity following a filling is normal, but if it persists for several seconds or longer (especially over weeks), it may be a sign of infection or inflammation of the nerves.
2. Swollen or Tender Gums
Gum tissue swelling, puffiness, or tenderness close to the afflicted tooth may indicate an infection that has spread from the pulp into the surrounding tissues.
3. Tooth Discoloration
When the tooth appears gray or darkened, it may indicate that the nerve has died or is dying, frequently necessitating a root canal.
4. Drainage or Pus Formation
The presence of pus, a foul taste in the mouth, or signs of an abscess (a bump on the gum) indicates a serious infection that typically requires immediate intervention.
5. Spontaneous or Throbbing Pain
If pain arises without provocation or wakes the patient up at night, the infection could have progressed beyond the filling site into the tooth’s nerve.
