Dentists use dental crowns when decay or damage have compromised the structure of a tooth beyond what a filling can repair. Constructed of beautiful, durable dental porcelain, crowns act as a cap for a damaged tooth and protect it against further harm. Many patients with aging or damaged metal crowns come to us for porcelain replacement crowns.
Dr. Greenfield can even create and place crowns in a single visit using state-of-the-art CEREC technology. This eliminates the need for unstable temporary crowns and return visits to the office.
Are Crowns Made of Any Materials than Porcelain?
Dentists can use several materials in the construction of dental crowns. Usually composed of gold alloy, metal crowns provided durability and reliability to dental patients before the development of more modern materials. Unfortunately, metal crowns do not blend in with the surrounding teeth and therefore lack much in the way of natural esthetics. To solve this problem, dentists developed porcelain-fused-to-metal (PFM) crowns, comprised of a metal substructure and a porcelain exterior. For the most part, PFM crowns look like real teeth. However, if the gums around the crown recede, the metal portion shows and gives patients a distinctive black or grey line at the gums.
Are Porcelain Crowns Better Than Metal Crowns?
At Lake Orion Family Dentistry, we only place porcelain and zirconia (a type of ultra-strong porcelain) crowns. While many dentists still place metal or PFM crowns, we believe metal-containing crowns are problematic. First, restorative dentistry should restore not only the function of a tooth, but also its natural beauty. Metal crowns and PFM crowns look artificial and detract from the inherent beauty of a healthy smile. Furthermore, so many people live with a metal allergy or a metal sensitivity that we find it beneficial to avoid the use of metal whenever possible. Porcelain crowns not only serve our patients better, they correspond with our holistic dentistry philosophy.
