Crowns and bridges are two of the most common types of dental restoration. Dental crowns are used to cover a tooth that is damaged or decayed. They are made using ceramics, resin, porcelain, and metals. Dental crowns do not need to be replaced as often as other dental restoration options.
What are dental bridges? Dental bridges help fill the gap created by one or more missing teeth. They are made from the same materials as dental crowns. Natural teeth or implants usually support bridges. Some of the factors that are required to consider when selecting a dental crown are durability, strength, and cost.
Types of dental crowns:
Dental crowns are designed to last for about twenty years when they are taken good care of. Patients can select their type of crown and some of the options include
Porcelain:
Porcelain crowns, the most popular type of dental crowns, offer a natural look and they can be colour matched to your existing teeth. Porcelain crowns are also strong and durable. It is recommended when the affected tooth remains forward-facing and is visible when you smile.
Resin:
It is one of the least expensive types of dental crowns. Resin crowns are not as durable as porcelain crowns and they may chip or break over time.
Gold:
Gold crowns are made from a gold alloy. They are strong and durable but they are also the most expensive kind of dental crown. They replace molars that are in the back part of the mouth.
Temporary Crowns:
A temporary dental crown is made from a different type of material than permanent crowns. They are usually made from plastic, acrylic, or composite resin material. Temporary crowns are also made from aluminium. It is made using such less durable materials because temporary crowns are made to last for a few weeks or days.
3/4 or Onlay Crown:
A 3/4 or Onlay crown covers the chewing surface of a tooth and one or more cusps. Your dentist may suggest Onlay crown when a full crown is not necessary.
Full or Traditional Crown:
A full or traditional crown covers the entire tooth. A traditional crown is recommended when a tooth is severely decayed or damaged.
One Day Crown:
It can be obtained immediately after the first appointment. Some dental clinics provide dental crowns on the same day of the appointment. The procedure is done by taking digital impressions of the teeth and then sent to the lab for fabrication. Once the crown is ready, it will be placed on the tooth.
