Dental Crown
What are Dental Crowns?
Why are Dental Crowns Needed?
In addition to root canals and wisdom tooth extractions, dental crowns are commonly used to address dental issues. There are different types of dental crowns, but let’s first understand their purpose.
A dental crown, also known as a cap, is a fixed prosthetic device that is permanently attached to a tooth with the help of dental cement. Once placed, only a dentist can remove it. The primary role of a crown is to cover and protect a damaged tooth. Additionally, it provides strength to the tooth, enhances its appearance, and helps it fit properly in the mouth.
To create a dental crown, the dentist takes an impression of the tooth or teeth that require coverage. Before taking the impression, the dentist may need to reduce the size of the tooth to ensure a precise fit for the crown. During the fabrication of the permanent crown, a temporary crown may be placed to safeguard the tooth.
Types of crowns
All Ceramic / Zirconia
Ceramic crowns are an excellent choice if you want strength without metal in your mouth. They blend naturally with your tooth color and have no aesthetic concerns. They work well for front and back teeth, including bridges. Unlike other crowns, they solve the problem of porcelain wear and visible metal. However, they may not be suitable for molars due to biting forces. These crowns are made of a porcelain-based material.
Porcelain-Fused to metal
Porcelain-fused-to-metal (PFM) crowns are the perfect choice if you value aesthetics and strength. They combine a metal interior for strength with a porcelain exterior that matches the natural color of your teeth. PFM crowns provide a natural appearance and offer a strong bond due to their metal structure. They are highly durable and long-lasting.
Metal
If you're seeking a long-lasting and durable solution, metal crowns are the way to go. Among them, gold crowns are particularly popular due to their strong bond with the tooth. They can withstand the pressures of biting and chewing with ease. Their strength also ensures they have a longer lifespan and are resistant to wear and tear. However, one drawback is that they are visible, making them more suitable for molars rather than front teeth. These crowns are made from a mixture of gold, copper, and other metals. They provide a reliable bond to the tooth, are resistant to fractures, and do not cause excessive wear on the natural tooth.
