That wobble after the new floor went in
If you just had new tile, vinyl plank, or laminate put down in the bathroom and the toilet feels a little different when you sit on it, you're not imagining it. A slight rock, a gap you can see under the base, or a ring of caulk that looks stretched are all signs the toilet is sitting higher relative to the flange than it used to. This is one of the most common callbacks in the Nixa area after flooring work, and it's almost never the flooring crew's fault. It's just physics. Add a layer of material to the floor and you've changed the relationship between the floor and the drain pipe underneath it.
Why this shows up so often in Ozark homes
A lot of homes in Nixa and the surrounding Christian County area were built in the 80s, 90s, and 2000s during the town's growth years, often on slab foundations with the toilet flange set at a fixed height during original construction. Many of these bathrooms have already had one or two flooring updates since then, layers of vinyl, then tile, then something else on top. Each layer stacks the flange lower relative to the finished floor. By the time you're on your third or fourth floor covering, the flange can end up sitting flush with the floor or even below it, instead of the quarter inch or so above the finished floor it's supposed to have.

What a low or buried flange actually does
When the flange sits too low, the wax ring has to stretch further to make a seal, and it often doesn't. That's when you get the slow, hard to trace leak that shows up as a soft spot or dark stain on the ceiling below, or a faint sewer smell that comes and goes. Around here, where a lot of bathrooms sit right above a finished basement or over a crawlspace with limited ventilation, that kind of slow leak can sit unnoticed for months. The humidity swings we get, dry summers followed by damp falls, hide small leaks that would announce themselves faster in a drier climate.
What you can check yourself
Before anyone reinstalls the toilet, look at the flange with the toilet removed. You want to see the top of the flange sitting at or slightly above the new finished floor, not flush with it and definitely not below it. A rocking toilet after reinstallation, even a small one, means the base isn't seated evenly on the flange or the closet bolts are only catching part of the slot. Pushing down on opposite corners of the bowl and watching for movement is a fair home test. If you smell sewer gas near the base, especially after the floor has had a few days to settle, don't wait on that. That's not a cosmetic issue.
Where this stops being a DIY fix
A flange that's slightly low can sometimes be corrected with a flange extender kit or a thicker wax ring with a horn, and plenty of handy homeowners manage that part fine. But if the flange is cracked, if it's more than an inch below the finished floor, or if the subfloor around it feels soft or spongy when you press on it, that's past the point of a simple fix. Soft subfloor usually means water has already gotten in from a previous bad seal, and that calls for cutting into the floor to check the wood underneath, not just swapping a wax ring. At that point you're better off having someone pull the toilet, inspect the flange and the subfloor properly, and reset everything at the right height before it goes back down for good.
A word about the timing
If you're planning flooring work in the near future, mention the toilet flange to whoever is doing the floor before they start. It's a five minute conversation that saves a callback later. And if the flooring is already done and the toilet is back in place, give it a week of normal use before you decide everything is fine. Small leaks around a marginal seal tend to show themselves once the caulk lines get walked on and the seasonal humidity shifts, which around Nixa usually means the first stretch of muggy weather after the work is finished.
