Dental crowns are a common and popular solution to severely damaged, decayed or unsightly teeth. They sit comfortably over the top of the affected tooth, restoring strength, shape, and creating an improved appearance.
Long gone are the days when we were limited to unsightly metal crowns that affected our confidence and smile. Developments in new dentistry technology mean that porcelain crowns are now an extremely popular option.
Although a widely performed treatment, porcelain crowns aren’t suitable for every patient. On this page we are going to take a look at the benefits and risks of porcelain crowns.
Risks of Porcelain Crowns
The biggest risk associated with PFM crowns is that the metal component can sometimes be seen through the porcelain coating covering the tooth, creating a ‘dark shadow’ within the tooth.
- All-porcelain crowns are not as durable as PFM crowns, and are more exposed to cracking and chipping. You should pay extra care when eating hard objects or participating in sports.
- More trimming is required for PFM crowns in order to accommodate the metal structure that gives it added strength.
- All-porcelain crowns are also more likely to result in teeth sensitivity, particularly to hot/cold temperatures. Exposure to these could also be strong enough to cause damage to the crown.
- All-porcelain crowns are more expensive than PFM varieties.
Benefits of Porcelain Crowns
By far the biggest benefit of porcelain crowns – and the main reason for their rapid growth in popularity – is the cosmetic solutions that they offer.
- Porcelain crowns can be color-matched to your existing teeth. Your dentist will also ensure that the size and shape matches your existing teeth, making this type of crown virtually imperceptible and giving you a natural-looking smile.
- Porcelain-fused to metal crowns (PFM) are also strong and durable thanks to the metal component supporting them. This means that with proper care they can last substantially longer than all-porcelain varieties.
- All-porcelain crowns don’t have the dark line associated with PFM varieties and look completely natural.
- The metal component of PFM crowns ensures that they are a better fit than all-porcelain crowns.
- All-porcelain crowns are made of biocompatible material, so there is no risk of gum irritation or allergic reactions.
- PFM crowns are significantly cheaper than their all-porcelain counterparts.
