One week ago I had tooth #19 prepared for a crown.   The tooth had a large filling which was old and chipped.The procedure went fine.   The injection of anesthetic took a long time to wear off - about 4 hours.   When it did wear off I had a tremor in my lower lip.   The tremor lasted for about 2 - 3 days.  It then began to improve but it is not completely gone yet.   It has now been 7 days.    Is this caused from the injection?   How long will it take to go away? I have called my dentist office twice - he has not called me back. Thank you.
Hello, thank you for consulting with Chat Doctor. The tremor which you are feeling on the lower lip can be because of trauma on the nerve due to injection. To get it confirmed you have to visit the dentist and get a full mouth x-ray done. And if there is something like that then you should start with medications called erosion capsules at least for month and see the response. Hope it will help you.
