Should You Replace Metal Fillings?

Have you noticed fewer people with metal fillings? It’s not because cavities have become less common. Instead, many people are choosing to swap out their old fillings with a metal-free solution. Although amalgam has been used for generations, tooth-colored fillings are a popular choice. Here are the top reasons you may want to consider replacing your metal filling with composite resin.

Disadvantages of Amalgam Fillings

Amalgam fillings have been the trusted solution for tooth decay for decades because they are effective and durable. However, they come with many disadvantages, like their dark appearance. They can also cause your tooth to darken over time. Not to mention, mercury exposure concerns are common. 

Amalgam fillings are made of a mixture of metals, including mercury. Although the American Dental Association supports their use, there are concerns about the risks associated with long-term mercury exposure. In addition, they can cause allergic reactions in patients with metal sensitivities.

Benefits of Tooth-Colored Fillings

Tooth-colored fillings resolve the disadvantages of the traditional method. A composite resin is shaded to match the color of your enamel to blend in with your tooth. White fillings allow you to enjoy many benefits not possible with amalgam, like:

• Look Natural: Your filling will look like part of your tooth, so only a trained dental professional will know it is there. You won’t have to worry about your tooth darkening, either.
• Biocompatible: Tooth-colored fillings do not contain any metals, so there’s no risk of long-term mercury exposure. There’s little risk of allergic reactions because they are also metal-free.
• Preserve Tooth Structure: Wedges aren’t cut into your tooth to support the filling. Unlike the traditional method, a weak acid is used to open the pores in your enamel to create a strong bonding surface for the resin. After it is applied and molded into the ideal shape, your dentist will use a special dental light to harden it in a matter of seconds. It’s less invasive and allows you to preserve more of your healthy tooth structure.
• Durable: Although composite fillings are metal free, they are durable. They can last for 5 to 15 years before needing to be replaced.
• Affordable: Many dental insurance plans can be used to lower the amount you’ll pay out-of-pocket for white fillings.

Don’t let a metal filling be a constant reminder of a previous cavity. Invest in a solution that will blend in while supporting your overall wellness. Your dentist can help you make the swap to a tooth-colored filling.
