Dental crowns, also known as “caps,” are placed over a tooth to preserve its functionality, improve its appearance, and restore its shape, size, and strength. Crowns are often used to protect a cracked tooth, restore a tooth that has excessive decay, or replace a pre-existing crown. Once the dental crown has been cemented into place, it will fully encase the entire visible portion of the tooth above the gum line.

There are three predominant types of restorative materials that are used in full coverage crowns:
2. All-ceramic (all-porcelain)
The material selected is determined by the clinical demands at hand, aesthetic demands of the patient, strength requirements, material durability and the amount of restorative space available.
Porcelain-fused-to-metal crowns provide patients with a strong, durable, and more aesthetically-pleasing treatment option. One of the key factors dictating the success of this type of crown is in ensuring the preparation of the underlying tooth structure provides adequate space for the material being used. Additionally, the artistic skill of the laboratory technologist creating the crown will determine its aesthetic appeal. One consideration in the porcelain-fused-to-metal crown is that these crowns may show the underlying metal or gold margin at the gum line as gums recede over time. Patients who opt for this type of crown often replace the crown at a later date in order to maintain this aesthetic benefit. To avoid this issue, we may recommend going with a porcelain-fused-to-metal crown with an all porcelain collar.
The predominant material used for all-ceramic crowns today is either zirconia or other aluminous materials. They provide a metal-free aesthetic option with a number of benefits. Additionally, the elimination of the metal core allows the tooth to look more natural. All-ceramic crown materials continue to evolve in strength and durability, but caution should still be exercised for areas of the mouth requiring heavy function.
Although not as popular a treatment option for aesthetic reasons, gold crowns are still indicated in some instances. For example, patients with strong bites and those with para-functional habits (such as grinding or clenching) might be better served with gold crowns. This traditional restorative material can provide stronger support to the remaining healthy tooth structure. Gold crowns also offer a level of durability that is appropriate for teeth located in the back of the mouth like molars, where they will not be highly visible and where there is limited occlusal space. Gold crowns can also offer greater longevity and require less preparation than porcelain and porcelain-fused-to-metal crowns. When chewing, gold tends to be less abrasive to the opposing tooth than porcelain, which helps to prevent wearing of the teeth.
