A month and a half ago my 11-year-old daughter injured a front tooth. Part of the tooth was still slightly attached to the gum and they pushed it back into its original position. After a month and a half, this tooth does not respond. The other central incisor and the canine also do not respond (she has no lateral incisor). Can the condition of the tooth (alive or dead) be seen on X-rays? Do these teeth need to be opened and treated immediately?
Thank you.

Dear Sir/Madam!

A response to electrical stimulation can confirm tooth vitality, but it cannot confirm non-vitality. Considering the girl's age, we can hope with relatively high probability for revitalization of the tooth (re-establishment of blood circulation that was interrupted by the injury, perhaps even re-innervation in the dental pulp). In view of this fact, we also decide on treatment (root canal treatment) somewhat later; X-ray, clinical picture. An X-ray image does not show the consequences of tooth death in the initial phase (periapical changes, as a consequence of infection of the dead pulp, are a relatively late consequence of the injury).

Have a nice day!
