Nerve removal from milk teeth can relieve pain and prevent further development of pulpitis. However, removing the nerve makes the tooth brittle and can cause the tooth to be prone to brittle splitting.
Once the nerve of a milk tooth becomes infected, the nerve needs to be removed or the tooth pain will persist. Infected pus in the nerve can also cause periapical infection, which in severe cases can lead to destruction of the capsule of the succeeding permanent tooth below. Removing the nerve of the milk tooth can effectively relieve the pain and control the further development of the inflammation.
The loss of nerve nourishment will make the tooth brittle, which will cause the tooth to splinter when eating hard food, so it is recommended to have a pre-formed crown restoration.
Therefore, there are advantages and disadvantages of removing the nerves from milk teeth. Once caries occurs in milk teeth, it is necessary to seek medical treatment as soon as possible, and try to retain the living pulp to prolong the life cycle of milk teeth.
