As society advances, people increasingly prioritize health, recognizing that strong teeth are integral to overall well-being.Most nutrients enter the body through the mouth, and digestion begins with chewing food thoroughly. Thus, a healthy set of teeth is fundamental to overall well-being. However, not everyone possesses perfect teeth. Most people develop cavities, and after fillings, teeth become less sturdy than before. In such cases, a dental crown can protect the damaged tooth.
Let's explore the different types of dental crowns available:
First, porcelain crowns. These are primarily designed for teeth affected by cavities or pulpitis. After filling, the original tooth loses vitality andand the tooth structure lacks nutrients. Improper chewing can cause the tooth to fracture from the center. A porcelain-fused-to-metal crown can extend the tooth's lifespan and allow normal chewing. However, the metal core inside this type of crown may cause discomfort in the mouth. Compared to natural teeth, the color tends to be duller, often appearing grayish at the gum line.
Alternatively, all-ceramic crowns primarily use zirconia. These crowns are more durable and undergo comprehensive analysis of the patient's natural tooth shape and color. The shade can be customized to match natural teeth, maintaining long-term color stability. They appear indistinguishable from real teeth and offer a longer lifespan without the potential oral health risks associated with metal. However, these crowns are significantly more expensive, ranging from several thousand to tens of thousands of yuan.
