A dental crown is a custom-made cap that fits securely over a tooth, restoring its size, shape, and strength in the mouth. Crowns are recommended in various dental cases because they cover the entire visible portion of a tooth above the gum line. They play a practical role when a tooth’s structure is compromised, and this can be caused by decay, injury, or treatment. Here is more information about different types of dental crowns:
PFM Crowns
Porcelain-fused-to-metal (PFM) crowns feature a durable metal base that is covered with a porcelain exterior. This type of crown offers a balance of durability and a more attractive appearance than full metal crowns. The metal layer means they do not match the natural look of some ceramic options. The metal understructure provides stability and can stand up to bite forces, which makes these crowns a choice for back teeth.
Regular wear on PFM crowns may become apparent as the gum tissues recede, sometimes revealing a thin metal edge. Dentists use PFM crowns for teeth requiring extra support, and they are useful for bridges, since the metal substructure adds strength for multi-unit spans. While some people prefer all-ceramic choices, PFM crowns remain reliable for many restorative needs.
Zirconia Crowns
Zirconia crowns are all-ceramic restorations made from zirconium dioxide, a durable crystalline material. These dental crowns offer superior strength and can withstand chewing forces, making them suitable for molars and teeth exposed to stress. While they are quite sturdy, some people find that exceptionally hard zirconia may impact other teeth over time.
Zirconia is biocompatible, resulting in few patients reporting reactions to this material. It is frequently used for individuals with metal sensitivities. Advances in dental technology have enabled zirconia crowns to come in shades that blend with existing teeth, enhancing overall appearance. Many people opt for zirconia crowns in areas where a durable, long-lasting material is required.
Dentists may recommend zirconia crowns for patients seeking a combination of function and a natural look. The material resists chips and cracks, increasing its longevity. Zirconia crowns typically serve as the material of choice for back and front teeth when strength remains a primary concern.
Lithium Disilicate
Dentists craft lithium disilicate crowns from a type of high-strength glass-ceramic that is both durable and aesthetically pleasing. This material offers lifelike translucency, which makes it particularly suitable for front teeth where appearance matters. Lithium disilicate crowns bond securely to your tooth, providing a stable fit.
Ceramic Crowns
Dentists craft ceramic crowns from porcelain or other dental-grade ceramics, offering a metal-free option. These crowns are used for front teeth, as their color and texture can be matched closely to other teeth. When selecting a crown, you might review these practical factors:
- Aesthetic requirements
- Tooth location in the mouth
- Bite force and chewing habits
Ceramic crowns are a good option if your focus is on appearance or metal-free dental work.
