Dental crowns are a common dental treatment used to restore damaged or decayed teeth. They are custom-made caps that are placed over the tooth to improve its appearance, strength, and function. There are several types of dental crowns available, each with its own unique set of advantages and disadvantages. In this article, we will explore some common questions about dental crown types and provide valuable insights based on research and expert opinions.

What are the different types of dental crowns?

There are several materials used to make dental crowns, including:

  • Porcelain-fused-to-metal (PFM) crowns: These crowns have a metal base covered with a layer of porcelain. They provide a natural appearance and are strong and durable.
  • All-ceramic crowns: These crowns are made entirely of ceramic material, such as porcelain or zirconia. They are highly aesthetic and blend seamlessly with natural teeth.
  • Metal crowns: These crowns are made of various metals, such as gold or silver. They are extremely durable and resistant to wear and tear.
  • Composite resin crowns: These crowns are made of a tooth-colored resin material. They are less expensive than other types of crowns but may not be as durable.

Which type of dental crown is the most durable?

The durability of a dental crown depends on various factors, including the material used and the patient’s oral hygiene habits. However, in general, metal crowns are considered the most durable. They are highly resistant to fractures and can withstand heavy biting forces. Metal crowns are often recommended for molars, which endure the most pressure during chewing.

Porcelain-fused-to-metal crowns are also quite durable, as the metal base provides strength and support. However, the porcelain layer on top may chip or fracture over time, especially if the patient has a habit of grinding or clenching their teeth.

All-ceramic crowns have improved significantly in terms of durability in recent years. Advances in ceramic materials, such as zirconia, have made these crowns highly resistant to fractures. They are an excellent choice for patients who prioritize aesthetics and want a crown that closely resembles their natural teeth.

Which type of dental crown looks the most natural?

All-ceramic crowns are widely regarded as the most natural-looking option. The ceramic material used in these crowns can be color-matched to the patient’s existing teeth, ensuring a seamless blend. The translucent properties of ceramic mimic the appearance of natural tooth enamel, resulting in a crown that is virtually indistinguishable from the surrounding teeth.

Porcelain-fused-to-metal crowns can also provide a natural appearance, especially when the metal base is not visible. However, the porcelain layer may appear slightly opaque compared to natural teeth, particularly in areas where the gumline is visible.

Metal crowns, although highly durable, are not as aesthetically pleasing as ceramic options. They are often used for back teeth where appearance is less of a concern.

Are there any potential drawbacks to dental crowns?

While dental crowns offer numerous benefits, there are a few potential drawbacks to consider:

  • Sensitivity: Some patients may experience temporary sensitivity to hot or cold temperatures after getting a dental crown. This sensitivity usually subsides within a few weeks.
  • Gum irritation: Improperly fitted crowns or those with rough edges can cause gum irritation or inflammation. It is essential to ensure that the crown is properly contoured and polished to minimize this risk.
  • Chipping or fracturing: Porcelain crowns, especially those without a metal base, may be prone to chipping or fracturing if subjected to excessive force or trauma. Patients who grind or clench their teeth may be at a higher risk.
  • Cost: Dental crowns can be relatively expensive, depending on the material used. While they are a long-term investment in oral health, the upfront cost may be a consideration for some patients.

How long do dental crowns typically last?

The lifespan of a dental crown varies depending on several factors, including the material used, the patient’s oral hygiene habits, and their bite forces. On average, dental crowns can last between 10 and 15 years. However, with proper care and regular dental check-ups, they can last even longer.

Metal crowns tend to have the longest lifespan, often lasting 20 years or more. Porcelain-fused-to-metal crowns and all-ceramic crowns have a slightly shorter lifespan but can still provide excellent longevity.

It is important to note that regular dental examinations and cleanings are crucial for maintaining the longevity of dental crowns. Dentists can identify any signs of wear or damage early on and recommend appropriate treatment to prevent further complications.


Dental crowns are a versatile and effective treatment option for restoring damaged or decayed teeth. The choice of crown material depends on various factors, including durability, aesthetics, and cost. Metal crowns are the most durable, while all-ceramic crowns offer the most natural appearance. However, each type of crown has its own advantages and disadvantages, and the decision should be made in consultation with a dental professional.

While dental crowns can last for many years, proper oral hygiene and regular dental check-ups are essential for maintaining their longevity. By understanding the different types of dental crowns and their characteristics, patients can make informed decisions about their oral health and achieve optimal outcomes.
