Check the Bolts
Before springing into full plumber mode, you should check the bolts first. The problem could be a simple loosening of the two flange bolts at the base of the toilet. Check the one on each side and if any is loose, tighten it. If you find a broken bolt, you should replace it.
Look for Signs of Leakage
The first major step to repairing a wobbly toilet is looking for signs of leakage. Check the base of the toilet carefully for signs of water. If you don’t find any, you can proceed to the next step. But if there are leaks around the base, it means that there is something wrong with the wax ring sealing the toilet horn to the flange opening.
Test the Floor for Gaps
Check the floor around the flange opening and try to find any gaps between the toilet and the floor. Watch out for small spaces, as even the smallest one can be an issue.
Insert the Shims
Once you identify any gaps, insert some shims to help level the toilet. The best shims to use are the small plastic ones with ridges. Wooden shims work, yes, but I do not recommend them as they are prone to moisture damage.
Caulk the Base
Now that you’ve done a good job of balancing the toilet, all you need to do is seal the gaps along the floor with caulk. This step is necessary for a finished look. It will also prevent mop water and crud from getting under the toilet base.
