After getting a root canal and crowns done, I have started having bad breath. Will changing crowns help?

Hi:You can use Luminuex Oral Essentials whitening strips on your crowns to remove external staining.Best,Dr. Maddahi

Check with an expert dentist to check the crown, if the smell is coming from that area, it must be checked for gum pockets, inflamed gums, excess cement , the fit and if there was a previous root canal going bad! You must find the cause.Best of luck

If the gap you describe is visible and it traps food then the crown restoration has to be re-done. The reason for a full crown placement is to preserve a tooth structure, but in no way it should affect cosmetic appearance let alone have undercuts that trap food. Talk to your dentist or find...

Hi:The crowns can easily be adjusted after cementation without removal.  Just go back to your denitst and voice your concern.Best,Dr. Maddahi

You can definitely replace your silver crown with a porcelain tooth-colored crown. This will provide a more natural looking result that blends in seamlessly with your smile. However, if your current silver crown is still functioning properly, you should weigh your desire for beautiful aesthetics...

Unfortunately once the crown or porcelain is adjusted, it will be very hard to add porcelain back on. You will benefit if you have an uneven bite to see your dentist or an expert dentist to do a bite analysis and see if there are interference in your bite, or do you have a stable bite? Best of luck
