Imagine having a decayed tooth repaired, painlessly, without drilling or shots of anesthesia to numb the area. Wishful thinking? Not if two studies being conducted at the University at Buffalo's School of Dental Medicine show positive results. In one study, funded by a $100,000 grant by Apollonia, LLC, researchers in the school's Center for Dental Studies are testing a nasal spray that numbs the upper teeth.The nasal spray study is testing the effectiveness in dental procedures of a topical anesthetic normally used by ear, nose and throat physicians when they operate on the nose. Patients who received this anesthetic for that purpose reported it also numbed their upper teeth, sparking interest in using it for dental procedures.
