  Traversability in relation with tides in thin-shell wormholes is revisited to
investigate the possibility of improving recently noted restrictive conditions
for a safe travel across a wormhole throat. We consider wormholes
mathematically constructed starting from background geometries which are
solutions of scalar-tensor theories as dilaton gravity and Brans--Dicke
gravity. The advantages of working within such frameworks are studied by
examining the dependence of the extrinsic curvature and tides at the throat
with the parameters determining the departure from pure relativity; the
associated behaviour of tides in the smooth regions of the geometries is also
analyzed. Other related but different approaches are briefly discussed in the
appendices.
