Dental anesthetics are currently stabilized for shipment with hydrochloric acid which, upon injection, can cause a stinging sensation. Before the anesthetic begins working, your body must naturally buffer the solution before it can be absorbed and numb the nerves. This is why, many times, the dentist gives an injection and has to wait 10-30 minutes before you begin to feel the full effect. Some patients have limited or slower ability to buffer. This means they may not ever feel completely numb, if at all.

At our office, we have the ability to buffer the anesthetic dose before the injection. A small amount of sterile sodium bicarbonate is placed into the anesthetic solution prior to giving you the injection. This dramatically increases the effectiveness of the anesthetic and reduces the time it takes to fully feel the effects. It can also reduce or eliminate the stinging sensation usually felt during the injection itself. in the past, I have had patients report not being able to get numb, even after having several injections in the same area. Buffering the anesthetic before the injection dramatically reduces these types of problems.

At our office, we always strive to make your visit as comfortable as possible, and buffered anesthetic is just another method to provide our patients with the best care possible.
