A biologic-response teether (150). The teether (150) has a shield (160) and one or two generally "T"-shaped bite portions (170, 180) projecting from the shield (160). The bite portions (170, 180) each define an elongated stem (171, 181) closest to the shield (160) and two arms (169, 168) that are coupled to and transverse to the stem (171, 181).
