Ghost pains happen after an amputation. In the case of someone who has recently had an arm amputated, he may experience pain in his fingers, even though the fingers are no longer there.These are caused by the brain's inability to acknowledge that the fingers are missing, and the pain results from the memory patterns still in place in the neural circuitry from the "stump", to the place in the brain where the pain was originally experienced.In the case of a root canal, the nerve inside the tooth is amputated. The patient may therefore experience ghost pain in the tooth for the same reason that the amputee experiences pain in his fingers. This type of pain may be sharp and shooting pain in the tooth, or a dull ache. These symptoms generally go away on their own and are either not treated, or are treated with a temporary course of Tylenol, Ibuprophen or another light analgesic.
