[header] How to avoid dental crown problems [title] Check the color. [step] Before getting the permanent crown inserted, your dentist will carefully match the color of the crown to the color of your teeth to ensure it looks natural. He or she should consult you, giving you a chance to approve or disapprove of the selection. 
Using a mirror, look in your mouth at the surrounding teeth to see if they are the same hue as the crown. Don't be afraid to reject your dentist's initial selection.
