I had a porcelain-fused-metal crown in a RCT tooth (upper 5 number) few days ago. Now I see a little gap with the next tooth and food is being attracted and trapped there. It become very difficult to take the food out even by dental floss or toothpick. My dentist says it is normal for a crown to have a minimum gap with the next tooth and dental crown shouldn’t be tightly fitted to next tooth. She advised me to keep it cleaned. But it is irritating me every time I eat meat. Pls advice me.
