A dental crown is a dental restorative material that caps or covers a tooth or an implant. Dental crowns are proposed by dentists whenever a large cavity becomes a threat. It shields the affected tooth and re-establishes the tooth’s characteristics such as its appearance, figure, dimensions, and strength.
When dental crowns get cemented into the place in need of help, it completely encases the whole part of the tooth that is visibly situated at and on top of the gum line. To know why it is essential for dental health, read the reasons below:
- To defend weak tooth from breaking apart or cracking
- To repair a broken or severely damaged tooth
- To envelop and provide support to a tooth when there’s not much left
- To securely hold a dental bridge
- To coat distorted or discolored teeth
- To cover up a dental implant
- To make a aesthetic change
In children, stainless steel dental crowns are recommended by pediatric dentists and can be placed on a child’s baby or milk teeth with the following functions:
- To rescue a damaged tooth
- To protect and maintain the tooth against the potential danger from dental carries, particularly when a child fails to perform oral hygiene on a regular basis
- To reduce the use of administration of sedatives or anesthesia in children
There are different kinds of crown to choose from, however, there are certain crowns that are recommended by dentists to serve a specific purpose:
- Stainless – Stainless steel dental crowns are pre-manufactured crowns worn on top of permanent teeth. The stainless steel crown guards the tooth and filling whereas the permanent crown is produced using a different material. This is commonly used in children for the reason that these do not have the need of several dental visits to put in its proper place. Apart from that, these are cheaper compared to specially made crowns and dental prophylaxis that goes with it.
- Metals – Metal crowns consist of alloys such as gold alloy and base-metal alloys. This type of crown is best used for out-of-sight molars. In this type of crown, only a few tooth structures are needed to be taken out. Plus, tooth wear to the contracting teeth is lessened. Since metals are tough materials, they can endure bites and chews and they rarely break into fragments, making them the most durable type of all dental crowns.
- Porcelain-fused-to-metal – This dental crown’s color can be coordinated to your neighboring teeth, something which metallic crowns can’t do. The downside is that its porcelain part is can chip off. Aside from ceramic crowns, porcelain-fused-to-metal crowns and normal teeth also look alike at one glance though if you observe it closely, the metal underneath the porcelain appears like a dark line. This type is preferred by dental specialists for anterior and posterior teeth.
- All-resin – All-resin crowns are the most economical type of all crowns. The drawback, however, is that they have a tendency to get fractured as compared to porcelain-fused-to-metal dental crowns.
- All-porcelain – This type of dental crown is also known as “all-ceramic”. All-porcelain crowns offer its users a natural color among all other types of crowns. Also, it is appropriate from people who have allergic reaction of hypersensitivity to metals. This type of crown is the best suitable for front teeth.
Its weakness is that it is not as tough as porcelain-fused-to-metal crowns. In addition, they wear away opposing teeth more than all-resin and metallic crowns.
Temporary versus permanent – Temporary or short-term crowns can be modified in the dental office while permanent ones are exclusively made inside a laboratory. Temporary dental crowns are composed of acrylic steel or stainless steel. They can be utilized as a provisional restoration until such time that the creation of a permanent crown is finished.
