Dental crowns refer to a cap that is bonded over the entire surface of a damaged tooth to encapsulate the portion of the tooth above the gums. It can be used to repair different types of tooth damage including cracked teeth, large cavities, discoloration, and misshapen teeth. They can also be used alongside other tooth restoration procedures such as root canal therapy, to strengthen the tooth, and dental bridgework to support a tooth replacement.
A cap helps to restore the size, shape, and strength of a tooth while improving its appearance. If you’re a suitable candidate for dental crowns, your dentist may recommend one of the following materials for your permanent crown:
Tooth-colored crowns that are fabricated entirely from porcelain are referred to as all-porcelain crowns, while those made entirely from ceramic are known as all-ceramic crowns. Dental composite resin is another tooth-colored material that can give you an aesthetic restoration. Composite crowns are highly affordable, but are arguably the weakest material for crowns since they’re prone to chipping, cracking, and rapid wear.
Your dentist may also recommend Zirconium, which is a fairly new dental material that produces crowns that are as strong and durable as metal crowns and natural-looking for an aesthetic restoration. They’re also biocompatible, meaning that they won’t cause allergic reactions, and can be fabricated at the dentist’s office for same-day crown restorations.
Porcelain-fused-to-metal crowns are generally fabricated with a metal base and porcelain coating, which gives them the strength of metal crowns and the aesthetics of tooth-colored crowns. However, porcelain-metal crowns tend to be abrasive to opposing teeth, which increases their wear rate. The metal ring on the crown may also become visible in the event of gum recession.
Crowns made from metal are the strongest and most durable option, plus they’re not abrasive to opposing teeth. Different metals can be used to fabricate crowns, including gold, platinum, copper, and alloys like nickel-chromium and cobalt-chromium. Most metal crowns are made from a blend of metals, like gold and the base metal alloys.
Tooth-Colored vs. Metal Crowns
Tooth-colored materials give the restoration a natural look, which makes them a popular choice for repairing front teeth in order to preserve the aesthetics of your smile. They come in different shades, so you can choose a specific color that closely matches the shade of your teeth to make the restoration unnoticeable.
Metal crowns are primarily used to repair back teeth because they’re strong and highly resistant, and they’re not visible when smiling, which makes aesthetics less of a concern. But they may not be suitable for people who’re allergic to metals or those with aesthetic concerns.
