While patients are usually grateful that local anesthesia blocks the pain that they might otherwise feel as a result of removing tooth decay with a dental drill, many dislike the discomfort associated with lingering numbness after they leave the office. Fortunately, there is something that can be done about this inconvenience. OraVerse® is an injectable drug (phentolamine mesylate) that reverses the effects of local anesthetic and allows patients to experience normal sensation in their lips and tongues about twice as fast as they normally would. As a result, patients can smile, speak, and drink sooner. OraVerse® is not recommended for use in children under 6 years of age or weighing less than 33 lbs.
P.S. The administration of OraVerse® does not hurt since it is injected into a part of the mouth that is already numb from anesthetic.
