A crown is like a thimble that fits around your tooth to restore it to its former glory. Dental crowns can be used for strength, durability and tooth stability, or for cosmetic reasons to enhance the appearance of a tooth. Crowns are often required when a tooth has been severely weakened and is no longer structurally sound. This can be as a result of trauma, tooth decay, previous root canal therapy or even general wear over time. This cosmetic dental treatment can also be used to brighten and improve the appearance of your smile. Crowns can cover broken, chipped, stained or discoloured teeth by modifying the shape of a tooth.They are very useful for:
Heavily worn, broken down or stained teeth for which the other options detailed above are not suitable for
Broken down teeth in patients who grind or clench their teeth heavily either at night or during the day
Teeth that have had root canal therapy, especially back teeth which can be at high risk of breaking afterwards.
Placement of a crown involves the following:
Sometimes, pre-impressions are required to assist with planning your treatment and the procedure afterwards
A preparation visit, where the tooth is shaved back into a mini tooth, an impression taken and sent to a laboratory and a temporary crown made for your tooth
A cementation visit, where the crown is tried on and fitted to your tooth.
Crowns can provide a very long-lasting result for your tooth and negate the need for constantly having to repair breakages over time. They can be tooth-coloured ceramic (useful where appearance is important), or metal (usually a gold alloy, very good for back teeth where a lot of force is applied).
