Can Numbness be Reversed? Numbness can be limiting, affecting your speech, your smile, and your ability to drink. You may even catch yourself drooling. Dr. Frazar’s office in Bellaire, Texas is pleased to offer a reversing anesthetic to our patients. OraVerse is a breakthrough that reverses unwanted lingering numbness after routine dental procedures where local anesthetic containing a vasoconstrictor was used. Patients are able to regain normal sensation twice as fast instead of the normal 3 to 5 hours. We would love to answer any questions you have regarding this great product in our Bellaire dental spa.
