Why Should You Replace Metal Fillings?

According to the Centers for Disease Control and Prevention, 92% of adults will experience tooth decay. Metal fillings have been used for generations to treat cavities, but concerns about long-term mercury exposure are leading people to look for alternative materials. White fillings are metal-free and look natural. Here’s why you should consider swapping out old fillings with a tooth-colored solution.

Are Metal-Fillings Safe?

Amalgam fillings are made of a mixture of metals, including mercury. The American Dental Association states that “Amalgam remains a safe, effective, and inexpensive dental restorative option;” however, a 2016 study by the University of Georgia found some concerns regarding their use. They examined patients with eight or more metal fillings and found an increased risk of mercury in their blood. The published evidence also discussed the benefits of replacing metal fillings with a safer and more aesthetically pleasing solution. Tooth-colored fillings are now the go-to method of treating decay.

Biocompatible Alternative to Metal-Fillings

Tooth-colored fillings do not contain any metals, so there’s no risk of mercury exposure or allergic reactions for patients with metal sensitivities. Instead, a composite resin is used to treat tooth decay. It is biocompatible and durable to provide long-lasting results that support your general wellness. In addition, the material can be shaded to match the color of the enamel to blend in with a tooth, so only a trained dental professional will know it is there.

Benefits of Tooth-Colored Fillings

Whether you have new decay, or you’d like to swap out an old filling, white fillings offer ample benefits, including:

• Look Natural: You won’t have a constant reminder of tooth decay from seeing a metal filling every time you look in the mirror. Composite restorations are customizable to look natural. They will not cause your tooth to darken over time, either.
• Minimally Invasive: Metal fillings require wedges to be cut into your tooth for support. Composite fillings do not use this method, so you’ll preserve more of your healthy tooth. Instead, a weak acid is applied to your tooth to open the pores in your enamel. This creates a strong bond between the filling and your tooth.
• Durable: Although composite fillings are metal-free, they are proven to last for 5 to 15 years with the correct care, like brushing and flossing.
• Affordable: Dental fillings are often covered by dental insurance. After meeting your annual deductible, your insurance will pay some of the expenses to keep your treatment affordable. 

If your filling is older than 10 years, it might be wise to have it replaced. If you have concerns about a metal filling affecting the appearance of your smile or your overall wellness, your dentist can help determine if tooth-colored fillings are the solution for you.
