Pros And Cons Of Dental Crowns Made Of Metal

Dentist Blog

Dental crowns are helpful for covering up large amounts of surface damage that a filling can't fix. Choosing the best dental crown material for your particular tooth is best left to your dentist, but you can certainly inform yourself of the options and discuss the pros and cons of each during your next visit. Fully metal or metal-backed crowns offer the best combination of stability, affordability, and cosmetic appearance.

Here are a few of the potential metal crown materials and the associated pros and cons.

Fully Gold Crown

The gold alloy used to create "fully" gold crowns is one of the most durable materials available. Durability means that the gold is suitable for placement on teeth that take a lot of bite force, such as the rear molars. After an initial set time, the gold is also resistant to temperature sensitivity and is unlikely to cause an allergic reaction.

The primary downside is that the gold is clearly not a part of your natural tooth. Some people like the look of a gold tooth, or the crown will be mostly hidden in the back of the mouth, so it wouldn't be a concern. But if you want a natural looking tooth, you might want to choose another crown material.

Fully Zirconia Crown

A fully zirconia crown is made of a white metal-based substance called zirconium dioxide. The result is similar in appearance to an all-porcelain tooth, though the zirconia doesn't look quite as natural as the porcelain. But the zirconia is more durable than porcelain and cheaper than gold.

The only real downside of zirconia is that physical properties of the metal make it better suited for a full tooth covering rather than a partial treatment. So this might not be the best option for you if the tooth only needs an overlay crown that sits on the very top.

Porcelain-Fused Metal Crown

An all-porcelain crown offers the most natural look but is also one of the weaker materials and can crack if used on a molar or other tooth heavily involved in biting. But Porcelain-fused metal crowns can offer the natural look with a stronger backbone.

Porcelain fused to a zirconia base tends to have better results than porcelain fused to gold. That's because the bonding cement forms a better seal between the porcelain and zirconia than the porcelain and gold. So a porcelain-zirconia crown is more durable and less likely to separate and allow the porcelain to chip off.

Now that you know the pros and cons of the different types of metal crowns available, talk with dentists, like Southridge Dental dentists, about the options that will best suit your circumstances, keeping these points in mind.

Baby Tooth as an Adult? You Are Not Alone

It was my secret for a long time, but I am finally sharing it -- I was an adult who still had a baby tooth. My dentist told me it shifted when my adult teeth came in instead of falling out. He also said I should have it pulled before it started causing dental problems, but I decided to keep it for a while. One day, during a dental check-up, my dentist found a cavity on the tooth next to it. He told me it was time to have it extracted, as it was close to the other tooth and making it hard for me to clean it. I had it taken out, and I don't miss it. I created this blog to tell other people with baby teeth as adults that they are not alone. Also, they can cause problems, so have them pulled if your dentist suggests it.
