Dental crowns are the visible part of the tooth, sitting above the gum line. An artificial crown covers this part of the tooth when it becomes damaged, protecting the natural tooth from further decay.
Dental crowns are an excellent treatment type for teeth that have severely decayed, are falling apart or have lost quite a bit of tooth structure. Usually, a root canal treatment is followed by placing a crown to reinforce the tooth.
Dental crowns are tooth-shaped ceramic tops that sit over a broken down tooth. They provide strength, stability and improve the appearance of a broken tooth by enclosing the visible portion of the tooth above the gum line. Dental crowns can also be placed over a dental implant.
Types of crowns
As the name implies, these are made out of metal and are incredibly durable and do not chip or break easily. The robust characteristics of a metal alloy makes them an excellent choice for molars as it can endure the bite pressure and grinding of teeth. The most significant downside is that the metal crowns stand out next to your natural teeth. They are particularly visible when laughing, smiling or taking pictures.
When considering crowns for out of sight molars or back teeth, full metal crowns are the most suitable crown type.
PMF crowns (porcelain fused to metals)
A fusion of porcelain and metal ensures the best of both worlds by providing a tooth coloured crown along with the durability of a metal crown. A metal alloy forms the inner core of the crown to provide strength and long life. Multiple layers of porcelain give the outer shell to the dental crown, therefore providing a durable solution as well as a tooth coloured crown. If you are considering crowns for teeth further forward in the mouth, PMF crowns are the most suitable crown type as this material resembles your natural teeth and seamlessly blends with the rest of the teeth.
A slight disadvantage is that sometimes the inner core of metal may become visible as a dark line at the gum line.
