Yes u can change it anytime,but once it's fixed u cant remove it,only a dentist can.

Yes you can remove your cap anytime if you want different varieties or quality. But some doctors use resin cement to fix and the cap cannot be pulled out. Instead we need to cut open and its time consuming. You may tell your dentist at the fixing stage if there are any issues and clarify the same before fixing that is one way. The other is tell your dentist not to use resin cement for bonding the cap. Finally choose a cap according to your shape, need and long lasting with good aesthetics preferably I would recommend Zirconium crowns are the best they come with warranty and superior quality unlike ceramic. Good Luck. If u feel to discuss personally u may Practo consult .

Yes you sure can

Your tooth shade is matched before the cap is been made in laboratory.So help your dentist for matching the shade u expected.There are less chances of error once you are satisfied with the shade

The cap once it is fixed has to be cut and removed as it cannot be pulled out without cutting. You can tell your dentist to fit it with a temporary cement for a few days to see if you are satisfied with the crown

Yes u can get it changed but it is better to look at a sample first nd decide ... you should first decide between different type of caps nd then get it fixed ...
