Dental crowns are fabricated caps that are used to protect and restore teeth which are damaged by excessive decay. Dental crowns are a full coverage restoration, so name, your dentist, will likely advise an alternative option such as one of the more conservative treatments available if possible before deciding upon dental crown as a procedure.
Dental crowns, Dental bridges and Dental Implants:
These terms can be confusing as they are all restorations for missing or severely decayed teeth. Dental crowns are used in treating teeth in which composite fillings alone will not suffice
Dental implants are used to replace missing teeth with a titanium screw to act as the tooth roots and a dental crown placed along the gum line to resemble a natural tooth.
A dental bridge is used in cases where two or more teeth are missing or decayed to the point where they require extraction.
A crown is placed on the adjacent teeth directly next to the missing teeth site. For example, if two teeth are missing, crowns will be placed on the natural teeth on either side of the missing tooth gap. These crowns are connected to tooth replacements which will be placed in the empty spaces where the natural teeth once were hence, forming a bridge.
Dental Crown Procedure
The dental crown procedure consists of first preparing the tooth by taking an impression to be sent to the laboratory so that the lab technicians may then make the customized restoration. During the time in which your dental crown is being fabricated in the lab, name ( Dentist) will fit you with a temporary crown so that the tooth will remain protected. Upon its completion, your finalized dental crown will be fitted and permanently bonded into place.
Some offices are equipped with CAD/CAM (computer aided design/ manufacturing technology) program in which a 3D picture of the teeth is taken and the dental crown is then created and shaped to the proper dimensions from a ceramic block. In this case, there is no waiting period, no temporary restoration, and no lab work. The entire procedure may be completed in one visit. Ask your dental provider if this option is available to you.
What is a Dental Crown Made of?
The material chosen to construct your dental crown will be determined by your esthetic preferences, the strength of the material required, the amount of space available for the crown and the durability of the material itself. The material options for the construction of a dental crown are listed below:
- Porcelain fused to metal
- All Porcelain (ceramic)
Gold Dental Crowns
Gold is no longer the most selected of the options listed for a dental crown due to today’s esthetics. However, in some cases in which the patient grinds, clenches the teeth, or simply has a strong bite a gold crown may prove more suitable for their particular needs. A dental crown comprised of gold will offer a stronger supporting structure and durability more suited for the molars in which the restorations are also less visible. In contrast with the other option available, a gold dental crown will not require as much preparation time, is more gentle on its opposing teeth hindering wear and tear, and has a longer lifetime than porcelain or porcelain fused to metal.
Porcelain Fused to Metal Dental Crowns
A crown that is made up of porcelain fused to metal is a durable, strong option that also accommodated for esthetic preferences. Patients should consider the fact that should the gum line recede over time, the underlying metal composition of the crown will be revealed and so some patients will chose to have the crown replaced with all porcelain or a porcelain fused to metal with an all porcelain collar to prevent this from occurring.
All-Ceramic Dental Crowns
Many patients undergoing crown treatment today opting for all ceramic crowns chose either aluminous materials or zirconia. An all-ceramic crown has no need for a metal core support structure and may be created so that the material itself is less thick making it ideal for smaller spaces. The crown is made solely of ceramic. The absence of a metal core allows for better light transmission throughout the crown creating a higher quality esthetic. The ceramic materials used are quite durable and strong. However, caution should be taken so as not to chip or crack the restoration.
Dental Crown Costs
As in all cases of dental treatment, the price of procedure will be influenced by the extent of treatment needed and the dentist’s experience and location. On average, the cost of a dental crown will range anywhere from $1,000 to $3,500 with a general life span of about 10 to 15 years
