Advantages, Disadvantages & Alternatives
Porcelain crowns are one of the most common types of dental restorations available for patients today, after tooth fillings. This solution is perfect for patients with decayed, damaged or darkened teeth, as crowns can be placed on virtually any tooth with a healthy root. The crowns themselves can be manufactured from a wide variety of materials but nowadays porcelain is the norm since it’s capable of offering great results in terms of survivability, strength and aesthetics. That being said, porcelain crowns may not be the best option for every patient – your dentist will put forward an alternative if that’s the case. Let’s take a look at a few porcelain crowns advantages, disadvantages and alternatives.
- Porcelain crowns are perhaps one of the most aesthetic solutions patients can opt for. The crowns themselves can be produced to match your existing teeth perfectly in terms of shape, size, colouring and translucence. Thus, the crown will be indistinguishable from your natural teeth, resulting in a natural looking smile.
- Porcelain crowns can be fused to a metal cap for extra strength and durability, making them last much longer than traditional full-porcelain crowns.
- All-porcelain crowns don’t have any dark lines or spots at the bottom, as is the case with porcelain fused to metal crowns, making them look much better.
- Porcelain Fused to Metal crowns fit much better than all-porcelain crowns, ensuring better durability.
- Porcelain crowns are biocompatible, meaning that there is no risk of allergic reactions to the materials or irritated gums.
- Porcelain fused to metal crowns are a bit more affordable than all-porcelain crowns.
- All-porcelain crowns don’t have a lot of disadvantages, but they are worth mentioning none the less. The biggest disadvantage of porcelain fused to metal crowns is that the metal part can be seen through the porcelain, appearing like a dark line at the base of the tooth.
- All-porcelain crowns offer less strength and durability compared to porcelain fused to metal crowns. They are also statistically more prone to chipping or cracks, especially for patients engaging in sports or eating hard foods.
- Porcelain-fused-to-metal crowns require more material to be removed from the tooth before placement.
- Porcelain crowns are more likely to cause sensitivity to very cold or hot foods.
- All porcelain crowns are somewhat more expensive than other types of crowns.
Full Metal Crowns – these crowns require less material to be removed from the patient’s tooth before placement. They are also very strong and able to withstand lots of pressure, making them perfect for patients suffering from bruxism. Full metal crowns are also more affordable than other variants.
Zirconia Dental Crowns – zirconia crowns are white and translucent, making them very aesthetically pleasing and offering a natural looking smile. These crowns are perfect for the visible teeth, such as the front teeth.
Porcelain Fused to Metal – these crowns look natural but due to their metal substructure are not recommended for the front teeth for example.
