There are four most common types of crowns:

  • Zirconia

This crown is made of zirconium dioxide and is a ceramic crown. The durability of zirconia crowns makes them enormously resilient to fracture. Zirconia material is the strongest non-metallic for dental crowns, although zirconia crowns do not fit like other crowns. According to a study, the monolithic zirconia crown is least likely to crack after taking a high-force bite.

When taking proper oral hygiene care, a zirconia crown can last up to 10 to 15 years or much longer.

  • Porcelain-fused-to-metal

Porcelain fused with metal crowns is quite a famous type of crown. They also give the most natural-look option to a person. Hence, they are well-suited for front teeth. Porcelain crowns have been the most prescribed cosmetic solution for teeth over the past 60 years. Although, the porcelain crown starts chipping, and as time goes by, the metal margin of the crown shows gums recede.

It lasts up to 5 to 15 years, and good oral hygiene and care can last longer.

  • Lithium disilicate

Dentists, with the help of specialized units, make disilicate lithium crowns in one office visit. It is currently the most trending crown material among people. It is a strong material and gets adjusted as per transparency, and they are appealing for cosmetics and fit well at the margins.

They last up to 5-15 years or longer with proper care and hygiene.

  • Gold 

According to a study, the gold material crown is still its “gold standard”. This crown has been people’s choice for around 100 years. However, a gold crown has a unique appearance. So, dentists recommend using teeth that are not visible when they smile.

Gold- it has a survival rate of 95% over ten years. However, a gold crown tends to last for decades with proper care.

Things that affect the lifetime of the crown:

The factors that can affect the lifetime of your crown are as follows:

  • Type of crown
  • The affected tooth health
  • Using teeth as tools
  • Grinding your teeth

However, the crown must be replaced when a gap between the crown and tooth is visible.

What’s the purpose of porcelain crowns, and why choose them?

When a person has a large gap to fill but not enough teeth to hold the opening, a crown is put in to strengthen the teeth. The dentist can use a crown to restore the broken teeth, protect a tooth that follows a root canal, protect a tooth from breaking, etc.

Choosing porcelain crowns is the best option for dental crowns as they look almost like a natural tooth, enabling the following tooth to function correctly. Hence, it is the most preferred type of dental crown. Crown materials like porcelain, metal alloy, resin, and PFM are used to make dental crowns.
