Ditloid Again

Checked with setter and no typing error, definitely S H H A T and is a phrase or saying, one of the words in which contains a body part.

So just S H H A T to solve in this very frustrating local quiz.

and asking for help or ideas once again, please.

Many thanks in anticipation.

Thank you ALL for trying so hard. Love Septuagenarians have hardly any teeth! and the setter is in her 70's so could be! Like also sixteen healthy human teeth as could be sixteen half human teeth -certainly cause(s) for thought. I, too, had made a list of poss body part but had missed thighs & trunk. Many thanks again, all of you.
