A dental crown is a cap that goes over the top of a tooth to protect it and make it look better. This cover is usually made of porcelain or resin, and it helps protect a tooth while restoring its colour, shape, and strength. Crowns also replace teeth lost by accident, disease, or tooth decay. A dental implant is an artificial root that is put into the jawbone to support and hold the crown in place when there is no natural tooth or root structure to do so.
A dental crown might be needed for several reasons. Your dentist might suggest one if you have a cavity too big for a traditional filling if your tooth is worn down, decayed, or otherwise weak, or if you want to cover up a badly stained tooth.
