What should I do if my tiger tooth hasn’t grown back in over a year?

The correct term for tiger teeth is maxillary cuspids, the maxillary cuspids have been lost for more than a year without growing out if the maxillary permanent cuspids are congenitally missing, then restorative treatment, if the maxillary permanent cuspids are blocked, then orthodontic treatment, if the faller is the maxillary permanent cuspids, then restorative treatment.
1. Congenital loss of maxillary permanent cuspids: the missing teeth can be repaired by fixed partial denture, and the abutment teeth can be chosen from ipsilateral maxillary mesial incisors, maxillary lateral incisors and maxillary first premolar, and the missing teeth can also be repaired by implant denture.
2. Maxillary permanent cuspid obstruction: Orthodontic treatment can be used to create a space for cuspid eruption, and then pull the cuspid to erupt and establish a normal occlusal relationship.
3. Lost permanent maxillary cuspids: Fixed partial denture or implant denture can be chosen to restore the missing cuspids.
It is recommended to go to a regular medical institution to receive professional treatment.
