You should check with whoever does the work on the car. (If that guy is you, then get a dial caliper and a digital camera, so you can post some observations and specific questions here). Check if any modifications have been made to stiffen the suspension (thicker torsion bars, sport shocks, antisway bars). Bushings can break down over time, even without a lot of miles. And a Porsche mechanic can test it and tell you if it's substantially different than other 911s.
Even stock, these cars have a harsher ride than your typical American sedan. You'll apprecate this less when you're running out for milk at the 7-11 than when you're racing through a canyon pass at speed. The stiffer suspension keeps the car planted better, with the wheels aligned more correctly with the pavement. It's possible to go too far, though, which leads to very poor handling (and possible molar cracking). If you suspect something is wrong with yours, get it checked sooner rather than later. If something is out of whack, then your dental work isn't the only thing that could be suffering from the abuse.
