Why Is Replacing a Metal Crown Right for My Smile?

Do you still have a metal dental crown in your mouth? Even though these highly durable restorations worked great at the time you got them, dentistry has come a long way since then. Now, there are other options that are more aesthetically appealing and healthier. Zirconia and porcelain have become the preferred material choices of many patients worldwide. Read on to learn from your dentist in Alexandria why you may want to consider replacing a metal crown with a nonmetal version.

Enjoy a More Youthful Appearance

Once people see a metal filling in your mouth, they may think that you are older. This is simply because metal crowns are an older type of dental technology. By switching to a zirconia or porcelain crown, you are likely to appear younger. Even for patients who have a zirconia-fused-to-metal crown, the metal may still be visible and add some years to your appearance.

MRI Interference

Often, MRIs are used in medical treatments so doctors can have a better look at the anatomy of the body. However, metal crowns can interfere with them because certain materials, like nickel and gold, respond when placed in a magnetic field. This can cause images to be distorted and they can even come off your teeth when they are drawn to or repulsed by the magnet. In general, crowns and MRIs aren’t a great combination.

Corrosion of Dental Implants

Titanium, the metal used for dental implants is not affected by magnetic fields, but it can help generate an electric current in your mouth. This happens when two dissimilar metals come together in a liquid with ions dissolved in it, such as saliva. This can lead to the weakening of one of the materials. Normally, titanium would not become weakened, but since gold is nobler, it could cause your dental implants to rust.

Higher Decay Risk

Even though dental crowns are meant to protect your teeth, sometimes they just conceal the damage, increasing the risk of decay. It’s a good idea to have your metal crown removed before this issue becomes irreversible.

Metal Crowns Contain Mercury

Humans aren’t naturally supposed to have metal in their mouths constantly. This is especially the case for the mixture of metals used to make crowns. They include materials like mercury and nickel. Both metals can have serious effects on your body in higher quantities. Mercury is well-known for being toxic and nickel can cause an allergic reaction. While metal dental restorations only have a small amount of these materials and haven’t been shown to be dangerous, many in the dental field agree that it is best to avoid these metals when possible.

Increased Tooth Sensitivity

People who have metal dental crowns are more likely to experience sensitivity to hot and cold foods and drinks. This is because metal is a great conductor of heat, so when more extreme temperatures contact a metal crown, you can feel it on your tooth. If you’ve been struggling with tooth sensitivity, your metal crown could be the main culprit.

Metal crowns may have their benefits, but zirconia and porcelain have become better options. In addition to having a more natural appearance, they offer health benefits as well. Talk to your dentist in Alexandria to see if switching to metal-free dental crowns is the ideal solution for you!
