Dental crowns are an effective solution for restoring teeth that are broken, worn down, or heavily decayed. They come in different materials, each with its own advantages and disadvantages. Before getting a dental crown, you should understand the different types of crowns available and the pros and cons of each. Here's what you need to know.

Porcelain Fused to Metal Crowns

Porcelain fused to metal crowns, or PFM crowns, are the most popular choice used today. They are made of a metal base covered with a layer of porcelain to match the color of your teeth. One of the pros of porcelain fused to metal crowns is their durability. They can withstand biting and chewing forces and last for many years. Plus, porcelain fused to metal crowns is often less expensive than all-porcelain crowns.

PFM crowns do have some drawbacks, however. Occasionally, the metal base can be visible near your gum line, and the porcelain layer can wear off over time, exposing the metal base. Additionally, some patients can have an allergic reaction to the metal.

All-Porcelain Crowns

All-porcelain crowns are very popular because they look most like natural teeth. They are made of a porcelain material without a metal base. The pros of all porcelain crowns are their aesthetic appeal, but they also have a strong ability to bond to teeth, providing greater strength and support than PFM crowns. All-porcelain crowns are also biocompatible and hypoallergenic, making them safe for patients with metal allergies.

However, all-porcelain crowns are not as strong as their PFM counterparts. In fact, they can be brittle and prone to cracking or chipping. Additionally, they are also more expensive than the other types of crowns.

Zirconia Crowns

Zirconia crowns are made of a strong, tooth-colored material called zirconia. Zirconia is a highly durable material and resistant to wear and tear, making it an excellent choice for crowns on your back teeth. In addition, zirconia crowns are biocompatible and hypoallergenic.

However, one of the cons of zirconia crowns is that they are not as aesthetically appealing as all-porcelain crowns. In addition, they can look opaque and may not blend in as seamlessly with your natural teeth, which is another reason they are often used exclusively on your back teeth.

Choosing the right type of dental crown depends on a variety of factors, including personal preference, budget, and the location of the tooth being restored. Porcelain fused to metal crowns is a reliable option for restoring back teeth, while all-porcelain crowns are recommended for front teeth due to their superior aesthetics. Zirconia crowns are a good choice for those who desire overall durability and strength. Be sure to discuss your options with your dentist to determine which type of dental crown is right for you.
