As we get older, many of us discover that our teeth that are no longer as structurally sound as they were in our youth. Your regular dentist will usually be able to recognize problem areas which may lead to tooth damage and a need for dental crowns
Grinding your teeth, an improper bite, age, fillings and tooth decay are all contributing factors in the erosion, cracking or breakage of your teeth. If the entire surface of the tooth is damaged, but the root system has remained intact, your dentist will usually suggest that a dental crown be put in place.
Dental crowns are also capable of replacing missing teeth entirely. The dental crown is secured to the teeth on either side using a bridge section which connects the two dental crowns. Alternatively, single tooth dental implants can be placed. This eliminates the need for supporting the dental crowns so no bridge is required.
Our dentist may recommend the placement of a dental crown for a wide range of problems but, in general, the majority of these reasons usually fall within one of the following basic categories:
- The restoration of a tooth to its original shape
- The strengthening of a weak tooth
- To improve the esthetic appearance of a tooth.
Types of Dental Crowns
Dental Crowns made of Resin and Porcelain
The new reinforced resin or bonded all-porcelain type of dental crowns has the most natural appearance as the color is specifically chosen to match the color of your teeth. They can be made from pure ceramic or a new reinforced composite resin, and as they are almost indistinguishable from natural teeth.
Dental Crowns Made of Gold
Gold crowns are often the preferred choice when the patient is not overly concerned about their appearance. Gold is extremely pliable making gold crowns a better fit than any other type. The strength and durability of the gold offers a more solid crown that will not chip or crack, which is possible with other types of crown. Gold crowns are normally used in molars, where the forces from chewing and grinding are most prevalent.
Dental Crowns made of Porcelain and Metal
Porcelain fused to metal crowns offer a natural appearance with a better fit than a standard porcelain crown. On the down side they have a metal substructure making it difficult to replicate the translucency of natural teeth. It is possible that a darker line will appear at the edge of the crown, near the gum, as it recedes with age. To overcome this problem, today we can change metal substructure with gold substructure.
