Sniff of local anesthetic could replace needle
from Medical News Today
Modern dentistry has eliminated much of the "ouch!" from getting a shot of local anesthetic. Now a new discovery may replace the needle used to give local anesthetic in the dentist's chair for many procedures. Scientists are reporting evidence that a common local anesthetic, when administered to the nose as nose drops or a nasal spray, travels through the main nerve in the face and collects in high concentrations in the teeth, jaw and structures of the mouth.
