A dental crown is a cap placed over a chipped or otherwise damaged tooth. Crowns fully encase the visible portion of the teeth to restore its optimal size, shape, strength, and appearance.
Dental crowns are needed to cover a weak, exposed, chipped, broken, or damaged tooth. They also cover dental implants, teeth treated with root canals, and keep dental bridges in place.
Permanent crowns are typically made from metal, porcelain and metal, resin, or ceramic.
Metal crowns are most common for molars and other less visible teeth, as they can withstand the pressure from biting and chewing. They are arguably the most durable crown material, as they last longer than other options and only require a small amount of tooth to be removed.
Porcelain and metal crowns can be matched to the natural color of teeth and are often used as crowns for front or back teeth. However, they are not as durable as metal crowns, as the porcelain can sometimes chip or break off. They are also not as resistant to the forces of chewing and biting, and the metal portion can be visible.
Resin crowns are less expensive, but the least durable of all crown options. Though their color matches the color of natural teeth, they break down more quickly over time and are less resistant to the forces of biting and chewing.
Ceramic crowns are the best natural color option and are often used for patients allergic to metals. Though they are not as durable as metal or porcelain and metal crowns, they are a good choice for front teeth.
Crowns can cover a portion of the tooth up to nearly the entire tooth and are an effective measure for restoring a healthy, attractive smile. Do you think you might benefit from a crown?
