Different types of Crowns
There are two common questions regarding dental crowns; what are they used for and what types are available. A dentist in Brooklyn was able to break it down in a simple and easy to follow way.
Dental crowns are used:
When a tooth has been damaged because of decay and it cannot support a filling
To protect the teeth of a child who is at a high risk of suffering tooth decay when oral hygiene is not kept up with
To decrease how many times a child may require general anesthesia because of medical history, behavior and age
There are many types of crowns available today:
Stainless steel is a prefabricated crown and it is used like permanent teeth or a temporary crown. This crown protects a filling or a tooth while waiting for a permanent crown to be made. A stainless steel crown is popular for children for fitting over a primary tooth which will be removed afterwards. A crown is used to cover an entire tooth and it protects it, so that it does not decay further. When a primary tooth comes out for making room for a permanent tooth, then the crown will come off in a more natural way with the old tooth.
Metal crowns are gold alloys or alloys with other metals. There is no need to remove too much tooth structure while installing metal crowns. A metal crown can withstand chewing and biting force and it generally lasts longer.
Porcelain fused to metal: they are made to match the color of the adjacent teeth, but the biggest problem is that the porcelain portion may break off or chip.
All-resin crown is not that expensive, but it will wear down faster and it is prone to some fractures compared to other types of crowns.
All-porcelain or all-ceramic dental crown offers a natural color match compared to other types of crown and it is suitable for people who suffer from metal allergies. The crowns are not as strong and they may wear down the opposite teeth.
