I want to offset faces of the 3 marked small surfaces.
It says it can't extrude non-planar faces.
I think i made them planar, can they become non-planar?
How to test if a face is non-planar?

You can SLICE a little the 3 teeth with the 3 points option, for instance.
Doing so, you'll get planar faces for sure.
You can use the command _SOLIDEDIT for this.
Select the >face editing option and then you can use either Extrude, Move or Offset to do what you want. There is no need for your face to be co-planar when you use this command.
I use SOLIDEDIT with the offset option, but it only offsets outwards, i mean i can only increase the volume of the solid, while i want to decrease.
I want to offset the 3 faces of the teeth to the origin of the UCS. i mark the distance between this origin and the edge of the tooth and it offsets outwards. now i try again but reverse the order of selecting the points: first the edge then the origin, but the result is the same, offsets outwards.
I used the Move option and it works, it moves the faces inwards to the origin.
There is a _move option in solidedit. Didn't you try it ? Offsetting or extruding may accept negative values but has its own direction ; perpendicular.
How can i give a negative value to the Offset option if i pick 2 points?
As i said, i tried with both ways to pick the same 2 points.

If you can't do it with the keyboard and that you really need to pick 2 points you can paste this expression in the command line :
(-(distance (getpoint)(getpoint)))
It will send a real number giving the negative distance between 2 points.
