There are four types of dental crowns. They include:
- Ceramic crown -The ceramics are perfect for restoring missing or damaged front teeth. They are a perfect choice since they can easily blend with the natural tooth color. The particular crown is made from porcelain.
- Porcelain fused to the metal crown-This crown has a stronger bond than the regular porcelain. That is because it has been connected to a metal structure. The metal makes this crown more durable.
- Gold alloys-This crown is a mixture of copper, gold, and other metals. The crown offers a very strong bond to the tooth. It does not fracture or wear the tooth. That is why it is very durable. The golden color makes it stylish too.
- Base metal alloys-It consists of metals that make up a very strong crown. These metals are highly resistant to corrosion. Before fitting the crown, the least healthy tooth ought to be removed.
Differences between the crown types
- The filling materials and strength of the tooth affect the sealing capability of the porcelain crowns. The other three crown types provide a better seal against damages.
- The gold and metal alloys crowns are highly durable compared to porcelain crowns that are less strong. They might damage the tooth when grinding the teeth. However, the porcelain that is fixed with metal is more durable.
The crowns might get loose and fall out sometimes. However, if they are properly maintained, they can last for a very long time. Practicing good oral hygiene enhances their durability.
