Crowns

A dental crown is a tooth-shaped “cap” that is placed over a tooth to cover and restore its shape and size, strength, and improve its appearance.
The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

Why Is a Dental Crown Needed?

A dental crown may be needed in the following situations:

  1. To protect a weak tooth (from decay, or previously Root Canal Treated tooth) from breaking or to hold together parts of a cracked tooth
  2. To restore an already broken tooth or a tooth that has been severely worn down
  3. To cover and support a tooth with a large filling when there isn’t a lot of tooth structure left to support the filling.
  4. To hold a dental bridge in place
  5. To cover mis-shapened or severely discoloured teeth
  6. Over a dental Implant
  7. To make a cosmetic modification

What Types of Crowns Are Available in Our Dental Surgery ?

Permanent crowns can be made from all Metal (such as Gold or another alloy which is called White Gold), Porcelain-fused-to-Metal ( PFM ), All Ceramic or Zirconia .

Metals : compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight ( Back ) molars.

Porcelain-fused-to-metal : With the use of Porcelain, the corwn can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal crowns. The crown’s porcelain

portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown’s porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.

All-ceramic or all-porcelain dental crowns provide better natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal crowns. All-ceramic crowns are a good choice for front teeth.

Zirconia or milled crown which is digitally constructed either in the dental surgery that has the software and hardware to produce them or in a specialized dental lab.

Temporary versus permanent. During the crown preparation procedures, and at the end of the visit, temporary crowns can be made in your dentist’s office, whereas permanent crowns are made in a dental laboratory. Temporary crowns are made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by a lab.
