Most dental work typically includes a local anesthetic that numbs the lips or tongue. The numbness can last for hours after the procedure. Smiling, talking, eating, and drinking can be extremely difficult while you are numb.
OraVerse (phentolamine mesylate) speeds up the return of normal sensation to your lips and mouth following dental work. Studies show that OraVerse, given as an injection after dental work is done, returns normal sensations in the lip, cheek and tongue 75 to 85 minutes faster than without the drug.
