Dental Crowns
Dental crowns is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. A crown is sometimes known as a ‘cap’.
Crowns are an ideal way to repair teeth that have been broken, or have been weakened by decay or a very large filling.
Crowns can be made of a variety of different materials with new materials are continually being introduced. Some of the most popular options are listed below.
Porcelain bonded to precious metal: this is what most crowns are made from. A precious metal base is made and then porcelain is applied in layers over it.
All-ceramic: this modern technique offers a metal-free alternative, which can give the strength of a bonded crown and the appearance of a porcelain crown. Therefore it is suitable for use in all areas of the mouth.
Gold-alloy crowns: gold is one of the oldest filling materials. Today it is used with other metal alloys to increase its strength, which makes it very hardwearing.

The Benefits of Having a Dental Crown
Dental crowns are perfect for restoring the shape, strength and appearance of a damaged tooth. Crowns protect the most vulnerable part of the tooth by holding it together and shielding it from potential damage. This means that after you have one fitted, you will once again be able to use your tooth to chew without risking damaging what is underneath it. Crowns fit neatly on the teeth just the same way sewing thimbles fit on the fingertips – they carefully fit over the top of a tooth and protect what’s underneath it.
Dental crowns can be crucial at restoring the structural integrity of your mouth and bite. It is no secret that when a tooth decays or breaks, it leaves an unwanted gap. The gap created can lead to further problems as it can easily interfere with your bite. By filling that gap with a crown constructed of resilient and durable materials that are designed to cope with the traumas of chewing just as effectively as the rest of your teeth, your mouth’s proper structure will be restored to a healthy state.
Crowns are also perfect for restoring the appearance of your mouth, as they are mostly indistinguishable from natural teeth and very hard to even notice.

How a Crown is Fitted
1)Â The dentist starts by preparing the tooth; this includes removing the tooth’s outer portion to ensure the crown will fit. If there is any decay, then this is also removed. If some additional tooth structure is needed to support the crown, your dentist may build up the core of the tooth.
2) An impression made from a mold or by digitally scanning the tooth is created to provide an exact model for the crown.
3) You may be fitted with a temporary crown while you are waiting for your new permanent crown to be completed and ready. This is a process that usually takes less than two weeks. During the period you have a temporary crown, the tooth may be fairly sensitive to hot and cold. It is advisable to avoid chewing gum and eating sticky foods during this time.
4) When your new crown is completed and ready, your dentist will place it in your mouth and make the necessary adjustments. Only once both you and your dentist are happy with how it looks and feels, the crown will be cemented into place.
