Do zirconium crowns harm the gums?

No, zirconium crowns are biocompatible and blend perfectly with the gums. The bruising and allergic reactions seen with metal-supported crowns are not experienced with zirconium. The gums adapt easily to the crown, maintaining a healthy appearance. However, gum recession can occur due to improper application or poor oral hygiene. Therefore, an experienced dentist and regular maintenance are crucial.
