installing new toilet when concrete floor is not level

The previous owner of my house installed a toilet on an uneven concrete slab. The toilet became wobbly and started leaking last week. We thought a new wax ring might be the answer and pulled the toilet to install it. From what I can tell, the main drain pipe (the one the flange goes over, was allowed to drift off vertical when the slab was poured. Add to this the fact that the slab was not leveled - so it looks like the flange was not even. Someone suggested that we build a level platform with concrete and install an extender drain and bolts. Any suggestions?

You can get beveled plastic shims made for the purpose to level the toilet with a level across the bowl (plumbing supply or big box store).
The flange should be bolted flush on top of the finished floor, and the toilet bolted snuggly to that, so that it won't wobble.
Once you get it level and bolted to the flange, you can use tub-and-tile caulk around the toilet base for looks.
Good luck!
