Methods for injecting a local anesthetic into dental tissues, such as tough, dense ligamentary tissue adjacent to a patient's tooth. According to one embodiment, the method involves puncturing a patient's gingival tissue adjacent a selected tooth with an array of micro-needles having a length so that the micro-needles penetrate into ligamentary tissue adjacent to the tooth. A local anesthetic is then injected through the micro-needles so as to deliver the local anesthetic to the tissue surrounding the tooth. The micro-needles may be short to limit penetration through tissue and of narrow diameter to minimize pain and discomfort to the patient. |
