Dental Crowns at Nuffield Dental Clinic Singapore

A dental crown is a tooth-shaped “cap” that is placed over a tooth. When cemented in place, it covers the visible portion of a tooth that lies above the gum line. Dental crowns can be part of your Smile Makeover procedure.

Benefits of Dental Crowns

Permanent crowns are typical with a metal substructure and a porcelain overlay. Other options include all ceramic, all resin, stainless steel and gold (with other alloys). It is very important to ask your dentist what metal you will be getting when you have a crown done. The amount of gold alloy determines how little corrosion there will be in the future. Patients are welcome to request for a higher level of gold content if necessary.

Crowns are used to protect weakened teeth (e.g. due to tooth fracture or after root canal treatment), to replace missing tooth structure (e.g. due to decay or wear), as part of a dental bridge or dental implant, to improve tooth shape and colour as well as close gaps between teeth.

Types of Dental Crowns

  • Stainless steel dental crowns
  • Metal dental crowns
  • Porcelain dental crowns
  • Zirconia dental crowns
  • Stainless steel dental crowns: When compared to other dental crowns, stainless steel dental crowns are the most affordable and easy to fit. This type of dental crowns is used as a temporary restoration.

Metal dental crowns: These dental crowns are alloys of noble, for eg – platinum, silver & gold) and base metals (i.e) nickel, copper & chromium. Metal crowns can withstand chewing forces well, however, the main drawback is the metallic colour.

Porcelain dental crowns: The outer layer of the crown is made of porcelain and these are considered to be one of the hybrid crowns. In order to have better appearance and durability, porcelain crowns are fused to metal crowns.

Zirconia dental crowns: When compared to other dental crowns, Zirconia dental crowns is one of the most popular types and made of ceramic. These dental crowns are worn to improve the appearance of a tooth. Zirconia dental crowns are long-lasting and easy to wear. Zirconia or milled crowns are digitally made either in a dental clinic that has the software and hardware to produce them or in a dental lab.

Dental Crowns Treatment Procedure

During the consultation, we would find out your expectations & concerns. The treatment will consist of detailed examination and x-rays may be required/recommended to assess the vitality of the tooth. The first visit is for the tooth preparation and the 2nd visit is to fit the crown. The tooth preparation is usually done on the local anaesthetic unless the tooth had root canal treatment.

Treatment consists of shade selection followed by careful removal of decayed and weakened areas of the tooth. Filling material may be used to fill in areas with large defects. The tooth is subsequently prepared to ensure that it has an optimal taper, well-defined margins, adequate ferrule and clearance from adjacent and opposing teeth. An impression of the tooth preparation is taken and sent to the dental laboratory to facilitate crown fabrication. A temporary crown is made and fitted over the prepared tooth in between visits.

On the fitting appointment, the temporary crown is removed and the permanent crown tried in. Your dentist will check to ensure that the crown is able to eat well, have good margins and is in contact (or suitable relationship) with adjacent and opposing teeth. He will also invite you to help assess the colour and overall appearance of the permanent crown. The crown is cemented in place once it is deemed to be satisfactory.
