When your dentist tells you that a crown is the next step, the conversation usually turns to options. Today, there are several types of dental crowns available, each with distinct advantages and drawbacks. The right one for you depends on where the crown is going, your budget, and your personal priorities. Read on to take a closer look at the five main types of crowns used in modern dentistry.
Gold Crowns
Gold crowns are a blend of gold, copper, and other metals. While they’re not the most discreet option, they’re incredibly durable. Dentists often recommend gold crowns for back molars because these teeth endure the most pressure from chewing.
Gold crowns require less tooth removal than other types, and they wear down at a rate like natural enamel. That said, their shiny metallic appearance makes them a less popular choice for visible teeth. Some patients may also experience allergic reactions to the metal alloy.
All-Porcelain Crowns
Porcelain crowns remain the top choice for patients seeking the most natural look. These crowns can be color-matched to your surrounding teeth, making them ideal for front tooth restorations.
Porcelain crowns are biocompatible, meaning they contain no metal and are unlikely to trigger allergic reactions. However, they’re not as tough as metal or zirconia options. Patients who grind their teeth may be advised to choose a stronger material. Porcelain crowns also tend to be more expensive.
Porcelain-Fused-to-Metal (PFM) Crowns
PFM crowns combine the strength of a metal base with the appearance of porcelain. They’ve been widely used for decades and offer a solid balance between durability and aesthetics.
The main drawback is that the metal core can sometimes show through at the gumline, especially if your gums recede. PFM crowns may also cause more wear on opposing teeth than gold or all-ceramic crowns. Still, they are a dependable choice for both front and back teeth.
Zirconia Crowns
Zirconia crowns are made from a high-strength ceramic material that blends the strength of metal with the look of porcelain. These crowns are highly durable and less likely to chip or crack.
Because zirconia is so strong, it can be milled in-office using special equipment. This speeds up the process and may eliminate the need for a temporary crown. However, their hardness can be a double-edged sword, as they may cause wear on opposing teeth. Adjustments can also be more difficult than with other materials.
E-Max (Lithium Disilicate) Crowns
E-Max crowns are the newest addition to the crown family. Made from lithium disilicate, they offer a high-end look without sacrificing strength. E-Max is a popular option for both front and back teeth when aesthetics are a priority.
While E-Max crowns are strong, they can be costly. Some dentists also prefer not to use them for multiple adjacent back teeth due to concerns over long-term durability.
