Evaluating Pain, Onset of Action, Duration, and Anesthetic Efficacy of Conventional and Buffered Lidocaine in Infiltration Anesthesia: A Comparative Clinical Study.

Summary: Getting a tooth pulled usually means getting a painful numbing shot first. Dentists wanted to see if adding a little bit of baking soda (called buffering) to the numbing medicine (lidocaine) would help make it better. They tested 100 adults who needed their back teeth pulled. Half of the patients got the regular shot, and the other half got the buffered shot. The results were very clear: the buffered shot hurt a lot less, worked twice as fast, and kept the mouth numb for a longer time. This simple trick makes going to the dentist much more comfortable!
