Metal-Bonded Crowns, Porcelain, or Zirconia Crowns: Which is the Best for You?

If you landed on this article, you are probably weighing out your options on the type of treatment or dental crown that will work best for you. Improving the appearance and the strength of your teeth is definitely a good decision. After all, your smile is one of the things people will likely remember about you.

One of the treatments to restore your teeth into good condition is a dental crown. A dental crown is a custom-made restoration that appears like a hollow shaped cap placed over a natural tooth. They may also be used for implants to replace missing teeth due to disease or accidents. Dental crowns are often made to restore the teeth’s strength, functionality, shape and size, and to overall improve its appearance.

There are different types of dental crowns. They can be made from all metal, all ceramic, porcelain-fused-to-metal (PFM), stainless steel, and all-resin materials.

Here is what you need to know about the different types of dental crowns before choosing the best fit for you.

Metal Crowns

As the name implies, this type of crown is made of metal. Known for their durability, metal crowns require the least tooth structure for removal as they are made into thin layers unlike other types of crowns. Metal crowns rarely chip or break as they provide a solid bond to the tooth and can withstand force due to biting and chewing.

The only disadvantage to metal crowns is they have a metallic color, which some people may not find appealing. This is why some dentists may recommend metal crowns for molars or those that are not easily visible when you smile.

Ceramic Crowns and Zirconia Crowns

Ceramic crowns are also called porcelain crowns. This type of crown is designed to mimic the appearance of natural teeth, which make it a popular option for those looking for tooth restoration. Ceramic crowns may also be a good choice for people who are allergic to certain metals used in other types of crowns.

However, ceramic crowns may wear out the opposing teeth more than metal and resin crowns do. In addition, more teeth structure may be removed due to the thickness of porcelain used to ensure sufficient crown strength. Less durable than metal crowns, ceramic crowns may chip and require additional care.

One of the types of ceramic crowns is the Zirconia crown. The modern zirconia can now produce the most realistic restorations, and its longevity makes it a good choice for those who wanting longer lasting results.

Zirconia crowns are the hardest and most durable among the ceramic types, as they can withstand the force from biting or chewing. They are also made to match the color of natural teeth, but not as translucent as porcelain crowns. The disadvantage, however, is that zirconia crowns may be abrasive and wear down the opposite teeth.

Porcelain-Fused-To-Metal Crowns

Porcelain-fused-to-metal crowns (PFMs) are among the common types you may find in dental centres. Dentists may recommend this type of crown for patients looking for long-lasting restorations.

As the name suggests, PFM crowns are made up of both metal and porcelain. The core is made of metal while the top layer is fused with porcelain to give it a finishing look much like that of a natural tooth. This type of crown gives patients the option to have durability and aesthetics in one. Unlike the metal crowns, PFM crowns can be used even for the frontal teeth because the color is almost identical to the natural ones.

However, compared to a full-ceramic crown, PFM crowns may not be as transparent. The metal underneath PFM crowns may become visible as the gum regresses over time. As PFM crowns are made of both metal and porcelain, they inherit the same disadvantages that come from both types of crowns. Like metal types, PFM crowns can also wear down the opposing teeth due to its abrasiveness. As they have porcelain layers, they may be prone to chipping.

How Do You Know Which is Best for You?

Not all patients have the same dental problems, which is why dentists may provide their treatment plans to restore a patient’s smile. This applies to choosing the type of dental crown patients may require to achieve that perfect teeth.

All these types of dental crowns have their own pros and cons.  Whether you are looking for durability or aesthetics, dental centres may provide you with a crown to fit your choice.
