Chipped, discoloured tooth can be restored by dental crown.
A crown is simply a tooth-shaped cap that places over a damaged or discoloured tooth to restore its shape, size and to improve its overall appearance. Crowns can be made of various materials: at our clinic we use full porcelain zirconium, Emax and porcelain-fused-to-metal crowns (including new high tech ceramics).
Patient can decide the shape, shade and colour of the crowns before the final fitting.
Porcelain-fused-to-metal crowns withstand the chewing force better, it rarely chip and more durable than full porcelain crowns. However, over time the metal underlying the porcelain layer can present black line at the gum line especially if the gums recede. These crowns can be used for the front and back teeth.
Full porcelain crowns can ensure the highest aesthetic result, however they don't last that long like porcelain-fused-to-metal crowns. Full porcelain crown can be used for front teeth and they are ideal choice for people with metal allergies.
When do I need a crown?
You may need crown in the following situations:
if a tooth is severely damaged or discoloured
if a tooth is worn down
if a tooth is weak to increase its strength (I.e after root canal treatment)
to cover dental implant.
