Crowns can be used to correct tooth colour and alignment defects, as well as structural damage to individual teeth. They can also be used to protect vulnerable teeth from future damage.
This process is more invasive than getting veneers, but it provides more reliability when added bite-strength is required. Crowns come in 3 basic types: all-Metal (Gold or Zirconia), all-Porcelain, or a blend of the two.
Gold is the most reliable and requires the least removal of tooth structure, but may not be the best cosmetic choice. For the best cosmetic choice, most people choose all-porcelain crowns. Sometimes an all-porcelain
crown requires the removal of more tooth structure than the other type of crown, and it also has a higher risk factor for cracking. PBMs (porcelain bonded to metal crowns) provide reliable cosmetic results while relying on the predictability of the metal for a tight seal.
Inlay and Onlay Restoration
When it comes to restoring teeth, there are many options available. We determine the best course of treatment by figuring out a balance of strength, durability, and conservation of tooth structure. As fillings get larger, teeth become fragile and more prone to cracking and breaking. To help prevent cracking and potential loss of teeth, crowns are often used to replace most of the outer surface of the tooth.
In some cases where a standard filling will not offer the strength and durability a tooth needs, a crown can be considered too invasive. For cases such as these, an onlay can be the ideal choice.
An onlay is a method of restoration that replaces an existing filling or a cavity, and covers some or all of the peaks of the tooth. Onlays are made from either a gold alloy or porcelain. The gold alloy option is the most durable, and tends to have the longest-term success, preservation-wise. However for some, an all porcelain onlay is the material of choice, at it has a more natural appearance.
