Most people who’ve had a root canal say they don’t regret it, even though many still have pain and discomfort in the affected tooth, a new Swedish study finds.
Root canals are commonly done when the soft tissue (pulp) inside the tooth is inflamed or infected. The soft parts are removed and replaced with a rubber-like material and a kind of cement.
“The studies show that the patients’ quality of life benefited from root canal treatment,” said study author Emma Wigsten, a dentist. “On the other hand, it’s unclear whether the treatment is cost-effective compared with tooth removal, especially where molars are concerned.”
