Nerve blocks to fill lips with filler?

while dental blocks may be performed, they are less popular now than previously...some people do well with only topical numbing salve or ice, but many people now favor injections just under the mucous membranes inside the mouth...and some of my patients actually prefer no numbing agents...irrespective of the choice of numbing agent, it should not interfere with the results of treatment...if your concerns resolved when the numbing disappeared, the cause of the problem was the effect of the block...not an adverse reaction to either the treatment or the numbing agent...

Administering a nerve block is a matter of personal preference
on the part of the patient and physician.The typical dental type inferior or superior alveolar nerve block avoids
the potential for distortion in the lip by delivering the anesthetic fluid to a
region which is actually several millimeters away from the actual site where
the filler is to be deposited. This technique avoids the risk for marked
swelling of the lip by anything but the filler material, the latter of which is
likely going to result in pretty uniform swelling throughout the lip on a very
temporary basis. However, you will also need to be prepared for that strange sensation in your lips and to not be able to speak clearly for about an hour due to the anesthesia.  Swelling that you experienced on one side of the face could be due to bleeding from contact with either the needle used for the filling material or from the needle from the anesthetic injection. The technique and availability of "needle free" filler administration has resulted in marked reduction of the risks for hematoma and is very well tolerated without the need for traditional nerve blocks.
