Tooth discoloration occurs after dental trauma, and this condition usually cannot recover on its own, mainly because after pulp necrosis, the pulp undergoes denaturation and produces substances that lead to tooth discoloration. This is an irreversible process. In this case, it is generally recommended that the patient go to the hospital, undergo a thorough examination, and after routine root canal treatment, consider changing the discoloration of the tooth by means of a crown restoration. For the front teeth, taking into account the aesthetics and stability, so it is recommended to carry out all-ceramic crowns or all-ceramic veneers, so that both can achieve aesthetic, but also be able to restore good chewing function.
