I received a new crown. It chipped within two days. Is this normal?

The dentist said it wasn't a problem but I still feel that it is not right. The crown it replaced lasted for years. The only reason I needed a new crown was because the original root canal was not done properly and need to be re-done. I don't think I should have to pay full price for a crown that chipped in two days. Although the dentist smoothed the place down, my tongue won't leave it alone (it's been several months now).
