question: For the past year and half i have been in the process of getting dental implants in the area of #11 and #13 I have had many dental injections.  I found many of the procedures painful so asked for numbing for the implant exposure and subsequent try-ins, these procedures were within 6 weeks then the last two were within a few weeks of eachother.  Each time i received about 7 injections, some were not very deep, just around the area.  All the work is finished and now i notice my upper lip twitches sometimes.  It feels strange.  I am sure this is due to so many injections over the year and half procedures.  It has been about two weeks since i received the abutments and crowns.  Will this twitching subside in time?  I am 72 and a retired dental hygienist, retired 7 years ago.  Thank you for any advice.
