| abstract |
A composition for anesthetizing oral or buccal tissues, especially periodontal pockets, is provided. The composition has a high concentration of topical anesthetic carried in a non-aqueous liquid vehicle containing a gelling agent. The anesthetics are optionally stabilized in the solution by ion-exchange complexation. The composition can anesthetize the gingivae for an extended period, such as 30 minutes or longer. Preferred anesthetics include tetracaine, benzocaine, butamben, and mixtures of these. |
