When teeth get fractured or severely damaged, sometimes a dental crown can be placed over them as a means of additional support and improve its appearance, alignment, or shape. Unlike dentures, crowns are permanent fixtures that are cemented onto your teeth or implants. Crowns come in a variety of different makes and looks, including porcelain, ceramic, gold, or other metal alloys. Depending on which tooth needs a covering and your dental history, certain crowns materials may be better than others. Speak to someone about whether a crown might be the solution for you.
