The maxillary frenum clamping tool includes two articulating members, each of the members having a clamping end and a gripping end. The clamping ends of the articulating members are curved to retract the upper lip while clamping the maxillary labial frenum and have blunt tips to minimize damage to the surrounding tissue. Immediately below the blunt tips, each member defines a jaw section having a serrated inner edge. The outer edges of the jaw sections define guide indentations for guiding a curved suture needle. The gripping end of each member defines a finger loop and part of a ratcheting lock mechanism for locking the members at set positions. During use, the clamping too may be used to clamp the maxillary frenum with the jaw portions so that the clamped tissue can be easily sutured using the guide indentations.
