“What foods should I avoid with a permanent crown?”

Ice cubes, corn nuts, those super petrified croutons, Milk Duds, Now n Laters, Rocks...

If you have a crown that fits well over an adequate amount of tooth structure you should have very few restrictions. Things that are really sticky and chewy like caramel and taffy should be avoided. Gum should be fine.

Any food or habit that can break your teeth can also damage your permanent crown. Most foods are OK. Very hard things like ice, peanut brittle, bones, etc can crack the porcelain. Very gummy, sticky items (gummy bears, jelly beans) can break the cement seal and pull the crown off your tooth.

Your permanent crown should be taken care of like you take care of your natural teeth. With crowns, you have a finish line where the end of your crown meets your natural tooth structure. This is the area that you want to make sure you floss. You floss your crown like you floss all of your teeth.
As a rule, my advice is to be kind to your teeth. Patients think their teeth and crowns are tools. A crown does not make your tooth stronger than your other teeth. If you don't know how to floss, ask your dentist. If your tooth had a root canal, you can develop cavities at the gum line. You do not have a nerve in a root canal tooth. Your tooth can have deep decay and you will not feel it. Flossing the gum line of all your teeth morning and night keeps gum disease at bay. Brushing at the gum line of all your teeth,( half tooth, half gum. cheek side, the tongue side, palate side, ). Clean your tongue with a tongue cleaner or a spoon with the rounded side facing up. Place the spoon in the middle of your tongue and go back as far as you can without gagging.
Scrape the center from back to front. You may find a lot of material in the nooks and crannies of your tongue, then do each side. Rinse your mouth with salt water, then gargle. Biting down on hard ice. Sticky foods. Flossing and brushing will keep your teeth.
