Why Replace a Metal Crown with a Metal-Free One?

For years you have worn a metal crown in order to protect a damaged tooth, but you’re seeing signs that it may be reaching the end of its lifespan. While it might be tempting to simply replace it with the same kind of crown, your emergency dentist may recommend switching to a metal-free option instead. Here are 4 major reasons why replacing a metal crown with a metal-free crown can be a great choice for your smile.

1. Metal-Free Crowns Don’t Conduct Heat

Do you ever experience pain in the tooth covered by your metal crown when you eat or drink something hot or cold? This is due to the fact that metal is highly conductive when it comes to heat. Metal-free crowns are made out of nonconductive materials such as porcelain, which means you’re less likely to experience discomfort when enjoying certain foods and beverages.

2. Metal-Free Crowns Result in a More Youthful Appearance

Crowns and other types of restorations are more common among older adults. Since metal crowns are very noticeable, they can end up advertising the fact that you needed to have your tooth repaired at some point, which can add to your perceived age. On the other hand, a metal-free crown can be personalized to match the appearance of your natural teeth, leaving you with a more dazzling grin.

3. Metal-Free Crowns Don’t Cause Issues with MRI Machines

Depending on what type of metals your crown is made out of, it could end up causing problems if you ever have an MRI scan performed. The interaction between the metal crown and the magnetic field could result in distorted images. Depending on the situation, you may be forced to have the crown removed so that you can undergo the scan. With a metal-free crown, you don’t have to worry about your dental work being an obstacle for MRI.  

4. Metal-Free Crowns are Often a Healthier Option

Certain metal crowns may be partially made of nickel, which can potentially trigger an allergic reaction and may even change the color of your gums. Other metal crowns might contain substances that can be harmful to the body, such as lead or mercury. Switching to a metal-free crown could be a wise move if you have concerns about how your current metal crown is affecting your health.

In short, by making the transition to a metal-free crown, you can avoid many of the drawbacks associated with traditional metal restorations. If you’re seeing signs that indicate that you might need a new crown soon, get in touch with your dentist to ask about getting a metal-free one.
