A dental crown is used to cap a tooth that is severely damaged. The crown holds the existing tooth structure in position and assists in restoring the size, shape and potency of the teeth. The crown encases the whole portion of the tooth that protrudes outwards from the gums.
Who Needs a Dental Crown?
A dental crown may be needed by people who:
- have weak tooth and are in need of protecting the tooth structure
- are in need of covering and supporting teeth with large amounts of filling
- have had root canal
- ihave fractured and damaged teeth
- are in need of covering dental implants and holding the dental bridge in position
- want cosmetic makeovers
- have to cover discolored teeth
Types of Crowns
Typically, the dental crowns are of the following five categories:
Gold Alloys Crowns
These crowns are composed of gold, copper or any other gum-biocompatible metal. These crowns are robust and provide a strong support to the weak tooth structure. They are extremely resistant towards corrosion and they do not wear and tear the tooth that they come in contact with.
Porcelain Combined with Metal Crowns
These crowns are combined with a metal to the inner surface. They are stronger as compared to ceramic or porcelain crowns, but the porcelain portion is still vulnerable to chipping. Crowns of this particular type can be designed to closely resemble the color and shade of natural teeth and are thus highly preferable for front teeth.
Ceramic or Porcelain Crowns
These crowns match the natural color of the teeth like no other type dental crowns, which makes them suitable for front teeth. Patients who are allergic to metal are advised to consider this type of crowns. These crowns cause wearing down of the opposing teeth more than metallic crowns.
Base Metal Crowns
Base metal crowns are made up of non-noble metals like nickel and chromium. They are resistant to corrosion and are gentle to the opposing teeth. They only require minimal removal of the existing tooth structure before cementing.
Milled or Zirconia Crowns
These crowns do not require the dentists to take a dental impression. These are fabricated through a computer aided design and manufacturing process. A 3-D image of the teeth is taken and the dentists can draw the exact shape of the crown that is used to restore the tooth.
The Process of Dental Crown
Typically, the process takes just two visits to a dentist’s clinic. In the first visit, the dentist examines the teeth and takes a dental impression. A temporary crown is fixed to the teeth. The patient is then dismissed. The time until the second visit is used to fabricate the crown in a dental lab, which may take up to two weeks. On the second visit, the permanent crown is cemented after the removal of the temporary crown. The procedure hardly takes twenty minutes.
