A crown is a 'cover' made of metal or porcelain, or a combination of these materials, that goes over a damaged or weak tooth. A crown is sometimes held in place by a post in the root of your tooth, if a lot of the tooth substance is missing. The purpose of a crown is often to restore damaged teeth. Crowns are also utilised for cosmetic purposes, to change the appearance of a tooth.
Frequently asked questions about dental crowns
How long does tooth preparation take for a crown treatment?
In preparation for a crown, your dentist will shape the tooth so that the new crown fits snugly over the prepared tooth. The time required to prepare your tooth will depend on the extent of existing damage to the tooth, and whether it needs to be built up with a filling first.
What do I do while my crown is being made?
A temporary, plastic crown is put over the tooth to cover and protect it while your custom, permanent crown is being made. You can chew on a temporary crown, but it won’t be nearly as strong as the finished one.
How are crowns made and fitted?
After preparing the tooth to be crowned, your dentist will use a soft, moldable material to take an impression. A dental technician uses the impression to make the crown the correct size and shape, and ensures that it will fit snugly over the prepared tooth. When the crown is fitted, your dentist will make small adjustments to make sure you can bite comfortably and that you are happy with its appearance. After trying the crown on and making adjustments, the crown is then glued into place as permanent fix.
