Nope.... its fine.
I have done that before... twice actually. And I still use them. Its pretty tough to clean though. The only thing that has changed is the heat distribution. It will not distribute heat evenly now. Some parts will be cooler/hotter than others. But since I paid a hefty sum for my pot... I just couldnt bare to toss it. So anyhew, cook away! :D You'll be fine.
