Local Anesthetics Side Effects
My daughter had a root canal procedure on 5-15-09 since then her half tongue is still numbed and has no taste bud.
What could cause this reaction?
Will she ever get her feeling back?
This sounds like damage to the lingual nerve, the one that supplies sensation and carries taste nerves as well, likely from the local anesthetic injection. This is a not uncommon event and most cases will resolve slowly over several weeks. In a very small percentage of the cases, the injury can be permanent.
You should tell the dentist as he or she will follow this for recovery and will want to know that this has occurred. The dentist can guide you further if needed.
