US Patent Number
A composition and method to alleviate oral mucosal discomfort and irritation in an orthodontic patient. A wax matrix containing less that 15% analgesic/anesthetic agent such as benzocaine and excipients enhanced and extended release of the analgesic/anesthetic agent compared to known art formulations. The composition exhibited desirable aesthetic properties, was easy to apply, and the relatively lower concentration of active agent provided enhanced safety.
