What Are the Different Types of Dental Crowns?

What Is a Dental Crown?

A dental crown is a cap that covers a damaged or weak tooth and helps restore the shape, size, and appearance of the tooth. They fit over your natural tooth and protect it from further damage. There are various reasons why a dentist might recommend a dental crown, which include:

• After a root canal
• To restore a broken or worn-out tooth
• Covering a dental implant
• To improve the discoloration of a tooth

A dental crown covers the visible part of the tooth and provides functional and aesthetic support.

Types of Dental Crowns

There are several types of dental crowns, each offering unique benefits. Here are the most common dental crown types:

Porcelain-Fused-to-Metal (PFM) Crowns:

A PFM crown has a metal base with the natural appearance of porcelain. They can withstand the pressure of chewing and blend perfectly with your natural teeth. However, the metal edge might become visible over time.

All Ceramic or All Porcelain:

These crowns are either made entirely from ceramic or porcelain, and they provide the most natural-looking smile. They are ideal for front teeth, however, they may be less durable for teeth that endure heavy biting pressure.

Gold Crowns:

Gold crowns are made from gold alloy and sometimes mixed with other materials, and they offer excellent durability. They can resist wear better than other materials. However, their drawback is the color, which might not be aesthetically pleasing for front teeth.

Zirconia Crowns:

These crowns are made from zirconium oxide and offer great strength and a natural appearance. They are highly durable and resistant to fractures, which makes them an ideal choice for both front and back teeth.

Resin Crowns:

Resin crowns are made from composite materials, and they are more affordable than other types. However, they are less durable, prone to wear and fractures, and rarely chosen.

How Dentists Choose the Right Crown

Dental experts look at different factors before choosing a crown type for their patients. Here are some important factors they consider:

• Tooth Location: Front teeth require a crown that looks natural, while back teeth require stronger materials that can handle chewing pressure.
• Strength and Aesthetics: Materials like gold and zirconia are highly durable. On the other hand, materials like all ceramic or porcelain are more natural looking but less resilient.
• Patient Budget: Dentists recommend a crown type within the budget of their patient. They find a solution that meets their functional and financial considerations.
• Allergies: If a patient has a metal allergy, then dental experts choose hypoallergenic metal-free options like zirconia or ceramic.
• Oral Health: Oral health plays an important role in the selection of a crown type. Dentists consider gum health, bite alignment, and tooth structure before choosing a crown material.
