Dental crowns are replacing a damaged tooth crown. In this article about dental crowns you will find when a dental crown is needed and which types of dental crowns exist and what differentiates them. The procedure of placement the dental crowns as well as their price is also discussed here.
A dental crown is used for restoring the aesthetic appearance and function of damaged tooth. It acts as an artificial replacement of the tooth’s crown. When cemented into place (on existing tooth or on a dental implant) it will fully encase the visible portion of the tooth above the gum line.
Although all dental crowns have the same function of replacing a damaged tooth crown, there are different types depending on the materials they’re made of.
The cheapest and most durable dental crowns are the ones made of stainless steel. However, they severely lack in aesthetics because of their metallic aspect. Their use may be temporary until a proper one is placed. Two important advantages is that metal outlast any other types of dental crowns and they are easier to work with –can be made to fit better. Although widely used long ago, the choice for gold alloy dental crowns have been replaced by patients opting for more natural looking porcelain crowns. Metal crowns might be uncomfortable for patients with teeth sensible to heat as metals are good thermal conductors.
They are made from a glass-like material and in terms of aspect it qualifies as a good looking replacement for natural teeth. However, porcelain and ceramic don’t last as long as full metal or porcelain fused to metal crowns, which constitutes their main drawback. It’s the best choice for patient that are allergic to metals.
Resin crowns have a great appearance, cost less, they blend the best of all crown types with the other teeth, but it’s also the least durable. Despite being much more prone to breaking than any other crowns, it may be the best choice for a patient that values most the aesthetic aspect and needs to restore a frontal tooth. A resin crown is suitable to patients that are allergic to metals.
These are the most common types of crown because of their natural look and feel and that they are more durable than all-porcelain crowns. Under the porcelain shell there is a metallic cap that adds structural strength when cemented on the tooth. Sometimes, due to the gum receding or bad crown placement, the metal underlying the crown porcelain might show as a dark line along the gum and crown contact line.
Zirconium dioxide has become the preferred material to use in dental crowns because of its aesthetic and functional properties. It is a strong material, doesn’t conduct heat, it’s non-metallic, free of corrosion and its margins never darken. Zirconium based dental crowns have almost the same translucency as the natural teeth and it eliminates completely the dark line at the gum line that may appear with porcelain fused to metal crowns.
The first step is being looked at by a dentist. After examining the tooth and its root by having X-rays, the restoration choices will be determined. A root canal may be needed in case the nerve’s chamber has been damaged. If a dental crown is what the dentist recommends, then the tooth will be prepared for its placement. An impression of the area will be taken so that the crown will integrate perfectly with the surrounding teeth. Until the crown will be manufactured (a couple of days up to two weeks, depending on the laboratory your clinic is working with) a temporary crown will be placed. The actual placing of the crown can be done in a 15 minutes appointment.
