What are the Different Types of Dental Crowns?

Dental crowns are a common dental procedure used to restore damaged or weakened teeth. They serve as prosthetic caps that are placed over a weakened tooth to improve its appearance, strength, and function. 

Crowns are also used to support a dental bridge. Additionally, they can be used to cover a discolored or misshapen tooth, improving the appearance of your smile.

Types of Dental Crowns

There are several types of crowns available, each with their own advantages and disadvantages. In this article, we will discuss the three most common types of dental crowns.

#1 Ceramic Crowns

Ceramic crowns are the most commonly used type of dental crown. 

They are popular because they can be matched to the color of your natural teeth, making them the most aesthetically pleasing option. They are also durable and long-lasting, making them a good choice for front teeth.

Ceramic crowns are sometimes made from a mixture of porcelain, ceramic, or glass, and are bonded to the tooth using dental cement. They are an excellent choice for restoring front teeth because of their natural-looking appearance. 

However, they are not as strong as metal crowns and may not be suitable for back teeth that are subjected to heavy biting and chewing forces.

#2 Metal Crowns

Metal crowns are a popular choice for back teeth because they are strong and durable. They are typically made from gold or silver alloy, which makes them resistant to wear and tear. Metal crowns are also easy to fit and require minimal preparation of the tooth.

While metal crowns are strong and long-lasting, they are not as aesthetically pleasing as ceramic crowns. They are also more expensive than other types of crowns, which may make them less accessible for some patients.

#3 Porcelain-Fused-to-Metal Crowns

Porcelain-fused-to-metal crowns are a popular choice for patients who want the strength of a metal crown with the natural-looking appearance of a ceramic crown. They are made by fusing a porcelain layer to a metal base, providing both strength and aesthetics.

Porcelain-fused-to-metal crowns are a good choice for both front and back teeth, as they are strong enough to withstand heavy biting and chewing forces. 

However, they do have some disadvantages. The metal base can sometimes show through the porcelain layer, giving the crown a gray or dark line at the gum line. Additionally, they can be more prone to chipping or cracking than other types of crowns.

Which Type of Crown is Best?

There is no one-size-fits-all answer to the question of which type of dental crown is best, as each type has its own advantages and disadvantages. 

The best type will depend on several factors, including the location of the tooth, the amount of damage or decay, and your personal preferences and budget.

What Type of Crown Lasts the Longest?

The longevity of dental crowns can vary depending on several factors, including the type of crown, the material used, and the patient's oral hygiene habits. 

Generally, the longest-lasting dental crowns are made from high-quality materials and are placed properly with good oral hygiene practices.

Among the types of dental crowns, metal crowns are known to be the most durable and long-lasting. They are made from materials like gold or silver alloy and can withstand the wear and tear of biting and chewing forces. Metal crowns can last for 20 years or more with proper care and maintenance.

While ceramic and porcelain-fused-to-metal crowns are not as durable as metal crowns, they can still last for many years if properly cared for. Ceramic crowns can last up to 10-15 years, while porcelain-fused-to-metal crowns can last for 15-20 years or more.

It's important to note that the longevity of dental crowns also depends on the patient's oral hygiene practices, including regular brushing, flossing, and dental check-ups. 

Conclusion

There are several types of dental crowns available, each with their own advantages and disadvantages. 

Ceramic crowns are the most aesthetically pleasing, while metal crowns are the strongest and most durable. 

Porcelain-fused-to-metal crowns offer the strength of a metal crown with the natural-looking appearance of a ceramic crown. 

The best type for you will depend on your needs and preferences. It is important to discuss your options with Dr. Nielsen, your Tempe dentist, to determine which type is the best choice for your dental needs and budget.
