Dental Crowns are dental restorations otherwise known as "caps" that fit over the visible tooth structure. A dental crown is different to a filling, because of one basic thing: a filling is placed inside a tooth and have walls of tooth surrounding it, whereas a crown fits over the damaged tooth and protects the remaining part of the tooth.
When Do I Need A Dental Crown?
- Teeth Reconstruction
Severely damaged teeth that can't otherwise be repaired in any other way and to replace the visible part of a tooth in Implant Dentistry
To prevent fracture of a weak or brittle tooth (often after a RCT)
To re-established the bite by giving the teeth different hights, widths or positions
- Teeth Aesthetics
To change the form / shape/ colour /size of teeth
Fringing opposing teeth into firm contact will enhance chewing capability
Types of Dental Crowns:
- Acrylic dental crowns
- Cast metal dental crowns
- Porcelain metal-free dental crowns (cosmetic)
- Porcelain with metal support underneath
- Fiber reinforced resin dental crowns
Cosmetic Crowns normally refer to full porcelain (non-metal) crowns, because of their highly aestetic look. Full porcelain crowns emit more light and are therefore more natural looking. Although these crowns are of a superior aestetic quality, they will cost slightly more than metal-porcelain crowns. The modern trend is to move away from metal and stronger porcelains are continuously being manufactured.
Dental Crown Procedure:
1) First Appointment:
- After numbing the mouth, the tooth gets prepared by doing a 360º preparation to ensure enough space for the fabrication of thedental crown
- Impressions are taken to be send away to a dental laboratory to cast plaster models in order to fabricated the dental crown
- A temporary crown / restoration is fitted to protect the naked tooth until the next visit.
2) Second Appointment:
- The temporary crown / restoration is removed and the new dental crown is fitted
Dental Crowns vs Dental Veneers:
There are some differences between Dental Crowns and Dental Veneers
Generally speaking crowns require more tooth reduction, but are more retentative (bigger surface area) than veneers. It is not possible to distinquish between a crown and a veneer on front teeth when someone smiles. The crown also covers the back section of the tooth that is not visible.
!NEW! The latest modern way is to make these crowns and veneers in 1 visit with special CAD/CAM technology. This is the future of dentistry and opens up an overwhelming new world of possibilities.

Care For Dental Crowns:
Cleaning dental crowns are very important since the underlying tooth is stil susceptable to decay, and proper general cleaining andhygienic procedures are advised:
- Daily brushing and rinsing with a fluoride mouth rinse (Dentyl / PLAX)
- Brush gently where the gum meets the dental crown
- Special soft pics are also an optional in the cleaning process
- Flossing is important to keep the dental crown margins free from plague accumulation
- Avoid biting on hard objects like ice or sticky foods
- Have your dental crowns check regularly with x-rays for early detection of decay
