Crowns are also known as “caps”. They fit over or “cap” the existing tooth, covering everything you see above the gum.
It is used to conceal a large filling, rebuild broken or fractured tooth, protect a tooth after root canal treatment, or for cosmetic dental purposes.
It is also used as a restoration over a dental implant to replace a missing tooth.
Dental crowns can be used for many reasons, including:
- Restoring a chipped, cracked or worn down tooth
- Protecting a weak tooth, such as a tooth with a root canal
- Supporting a dental bridge
- Concealing a large filling
- Restoration over a dental implant
- Cosmetic dental purposes, like covering misshaped or discoloured teeth
A dental crown or permanent tooth cap can be made of metal, porcelain-fused-to-metal, or full-ceramic (porcelain), suiting anyone’s needs and budget.
Metal crowns tend to last the longest, rarely chipping or breaking, causing minimum wear to other teeth. Because of their colour, these crowns are best used for molars.
Porcelain-fused-to-metal crowns can be colour matched to the natural tooth. However, there is a higher chance of them chipping or breaking as oppose to all-metal crowns.
All Ceramic (Porcelain Crowns) provide the best natural colour match, but are not as strong as metal or porcelain-fused- to-metal crowns. They are a good choice for front teeth.
A typical dental crown requires at least 2 visits.
First Visit: Tooth preparation and impression is made on the first visit.
The tooth preparation allows for adequate room for the crown.
The prepared tooth will be protected with a temporary crown in between visits.
Second Visit: The crown is ready for fit on the second visit. The crown is cemented once the patient and dentist are satisfied with it.
How long do dental crowns/ tooth caps last?
A dental crown can last anywhere between 5 to 15 years. They should be brushed and flossed, just like cleaning natural teeth. Crowns and tooth caps may not be as strong as natural teeth, so it is important to remember to not bite down on hard objects or to use your teeth to open or cut things – which is also not advisable with a set of natural teeth.
Cerec Digital Crown
Modern aesthetic ceramic restorations use digital technology to create highly accurate and beautiful restorations.
CEREC Crown (Digital Technology) is the unique CAD (Computer Aided Design) / CAM (Computer Aided Milling) system for patient individual all-ceramic restorations in one single appointment:
- Digital impression
- Receive your dental crown after teeth preparation in single session (Patient will be informed of suitability during consultation)
- No need for temporary fillings and crowns
- Highly aesthetic
The process entails:
- Appointment & patient education
- Remove decayed tissue or defective fillings
- Tooth preparation
- Create a 3D image of the tooth using the CEREC camera
- Crown is designed on the CEREC software
- Milling & manufacturing of the crown in-clinic in a milling machine
- Fit and bond the Crown directly on your tooth
It removes the need for a second appointment and increases patient’s comfort as a traditional impression of the teeth is no longer needed.
Instead, a scanner is used to capture photographic images of the cavity and these images are sent to a computer.
