Bend to look around for dressing (5)
I believe the answer is:
gauze
'dressing' is the definition.
(gauze is a kind of dressing)
'bend to look around' is the wordplay.
'bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'to look' becomes 'gaze' (gaze is a kind of look).
'around' indicates putting letters inside.
'u' going within 'gaze' is 'GAUZE'.
'for' acts as a link.
(Other definitions for gauze that I've seen before include "Thin transparent material" , "Medical cloth" , "Very fine wire mesh" , "Surgical dressing of muslin" , "Medical dressing" .)
