The words “root canal” often make patients nervous, but modern root canal therapy is designed to relieve pain, not cause it. Root canal treatment saves infected teeth and helps prevent extraction.
Understanding the warning signs can help you seek treatment before complications develop.
What Is a Root Canal?
Inside every tooth is a soft tissue called the pulp. When this tissue becomes infected or inflamed, root canal therapy removes the damaged tissue, disinfects the tooth, and seals it to prevent future infection.
Common Signs You May Need a Root Canal
Persistent Tooth Pain
Pain that lingers or worsens over time may indicate pulp damage.
Extreme Sensitivity
Sensitivity to hot or cold that continues after the stimulus is removed may signal nerve involvement.
Swollen Gums
Localized swelling near a tooth can indicate infection.
Tooth Discoloration
A darkened tooth may suggest internal damage.
Pain While Chewing
Pressure sensitivity often occurs when infection reaches deeper structures.
Dental Abscess
A pimple-like bump on the gums may indicate a serious infection requiring prompt treatment.
