I have some toy wooden bricks that I want to repair, they are fairly
intricate in shape as they have a keyway thats slots onto a vertical
T-shaped key.

I can get them basically back together by gluing but that leaves some
dents (the dog chewed them!) and splits that need filling.

So what would people suggest for finishing the repairs (and/or some of
the initial gluing), am I after a glue that can fill cracks or am I
after wood filler (or some other sort of filler)?

I'm concerned that wood filler may not adhere well enough on the
fairly small dents and splits. On the other hand I can't find any glue
that seems to have the properties I need. PVA glues mostly
specifically say that the joints need to be tight and well fitting,
polyurethane glues expand and fill gaps but I don't see it being easy
to use them to fill and smooth cracks. Would I be better off using a
silicone sealant of some sort? The bricks are painted so the colour
and texture of the result don't matter too much.

Any ideas would be most welcome.
