How many years after the tooth kills the nerve

The dental pulp in the middle of the tooth contains rich nerves and blood vessels. The main role is to nourish the tooth hard tissue and provide normal mastication function. If the tooth kills the nerve, the tooth hard tissue will lose the nerve blood supply and become brittle. At this time, crown restoration should be carried out in time after root canal treatment, that is, porcelain inlay. The tooth will last for a long time, even for life, if root canal treatment is performed properly and crowns are restored at the right time. However, if crowns are not restored in time, the tooth may crack when eating, and it may be necessary to extract the tooth.
