External Resorption is another rare dental condition that can be corrected with a targeted procedure. Although the condition can manifest after cysts, tumors, and chronic inflammation, a common cause is dental trauma. If your tooth had been knocked out and replaced, your body may rush to heal the nerve and tooth inside by “eating away” at the root.
The procedure starts with cleaning out the root canal system and placing calcium hydroxide to neutralize and stop this process. The root canal is then filled with gutta percha after the treatment is completed.
There may be a need to repair the exterior root surface surgically depending on the situation.
