Do you still have some metal fillings, also known as “amalgam fillings,” in your teeth? This type of restoration has all sorts of different benefits. For instance, they are effective when it comes to replacing areas of the teeth that have become damaged by decay, they’re long-lasting, and they are relatively affordable. However, there are some downsides as well that may overpower their advantages, especially now that there is a better alternative. Read on to learn why you should choose a tooth-colored filling instead.
What Are the Cons of Amalgam Fillings?
Metal fillings used to be the go-to option for many years, and many people still have them today. However, they aren’t always your best choice when it comes to restoring your teeth. Here are a few reasons why:
- Metal Fillings Contain Mercury: Amalgam fillings are made from several different metals, like silver, tin, copper, mercury, and others. The issue is that mercury is toxic to the human body. According to a study done by the University of Georgia, if you have more than eight metal fillings, they could be increasing the mercury levels in your blood. Ingesting high levels of the substance can cause “mercury toxicity.” This means symptoms like impaired senses and a lack of coordination. It can even be lethal in higher doses. The good news is that there isn’t any evidence to suggest that the amount of mercury present in fillings can cause major issues, but many agree that it is still a good idea to choose another option when possible.
- Temperature Reactions: Metal expands and contracts when exposed to different temperatures. When you eat hot foods, metal fillings can expand and put extra stress on your tooth. When you have something cold, it can shrink and cause gaps. In the end, this can weaken the natural tooth structure.
- Not Natural Looking: Metal fillings are far from invisible. Most people don’t like the appearance of amalgam fillings in their teeth because they don’t appear like natural tooth enamel.
What Are the Pros of Tooth-Colored Fillings?
Dentists today usually use tooth-colored fillings. Here are just a few of their benefits:
- Natural Appearance: Tooth-colored fillings blend in with the rest of your teeth. No one will even know that you have one.
- Mercury-Free: Tooth-colored fillings are made from a composite resin and don’t contain any mercury.
- Preserves Tooth Structure: Less of your healthy tooth structure needs to be removed to place a tooth-colored filling. This is because they are able to form a stronger bond with the tooth.
If you are needing a new filling, you may want to ask about tooth-colored fillings. By opting for this safe, natural-looking alternative, you can show off your restored smile with confidence!
