A reliable way to restore a tooth after a cavity or minor damage is with a dental filling. They allow you to regain function, so you can enjoy a strong bite once again. In the past, you could only get them made from amalgam, which is a metal material. As dentistry evolved, a tooth-colored option became available. So, should you replace your old filling with a modern one? Here’s what you should know.
What Are Amalgam Fillings?
In short, amalgam fillings were made from a metal alloy. Half of the composition would be gold, silver, or tin, but the rest is mercury. This is used as a binding agent, allowing the material to be malleable until your dentist shapes and bonds it in place. They are sturdy, and your results could last for up to 15 years or longer with proper care. This makes them a long-lasting solution, but they tend to stand out against enamel.
Can Metal Fillings Be Harmful?
Over time, research has come out showing that mercury is harmful to the human body in high amounts. It can cause neurological symptoms, like muscle weakness or headaches, and increase your risk of certain types of cancer. That said, if you just have one or two amalgam fillings, then you don’t really have anything to worry about. Although they can still release a vapor that can be trouble for those who are:
- Pregnant or nursing
- Younger than six years old
- Naturally more sensitive to mercury
- Have impaired kidney function
- Struggle with neurological disorders
Do You Need to Replace Your Amalgam Fillings?
In the end, a couple of metal fillings aren’t anything to stress about. However, if you fall into any of the categories above, then it may be worth looking into replacing them. Thankfully, your dentist and physician are here to help. By having a consultation, you can understand whether you have health concerns that can be prevented by swapping them.
That said, if your amalgam restorations aren’t any trouble, then it may not be worth the hassle of swapping them. Though if you don’t like how obvious they look in your smile, then that’s a good enough reason to! It just depends on your goals and needs. Keep in mind the points above, and you can feel confident making a choice you won’t regret.
