Abstract: A comfortable harness device for tensioning the temporomandibular joint. The harness has a plurality of pliable, but substantially non-elastic bands. A first band encircles a wearer's face and passes under the wearer's chin. A second band is attached to the first band and with the first band forms a cup for the wearer's chin that applies a posterosuperior force on the chin. A third band is attached to the first band and embraces the posterior portion of the wearer's head adjacent the wearer's temples. A fourth band at the base of the wearer's skull may be attached to the first band adjacent the wearer's chin.
