509-781-6600 Local anesthesia targets the pain receptors in a specific area of your mouth. Our dentist will inject it where it is needed, which will bring up to several hours of numbness. Most of the time, a local anesthetic is enough to prevent pain throughout the procedure and in the hours following. Ask Dr. Kent Copeland or our team if you have any questions or concerns about the use of local anesthesia in Prosser, Washington. You may call us at 509-781-6600 or visit us at Chardonnay Dental.
