Abstract: An improved teething apparatus having a constant pliability over a broad temperature range whereby the pliability of the teething device remains substantially constant regardless of its temperature is provided. The teething device includes a resilient, fluid impervious body member sized to be received in a mouth of an infant. A body of self-sustaining, non-flowable, pliable gel is disposed in the interior cavity of the body member such that the body of gel substantially fills an interior cavity of the body member. The body of gel is characterized by the properties of maintaining the self-sustension and pliability over a temperature range of from about -20.degree. to 215.degree. F. whereby the body member and the body of gel can be heated or cooled over a temperature range of from about -20.degree. to 215.degree. F. without substantially altering the resilience of the body member and the pliability of the body of gel.
