Understanding the Importance of Mercury-Safe Dentistry

In the past, mercury was commonly used in dentistry. Specifically, it is a major component of silver amalgam fillings, which are also known as metal fillings. Today, many practices have completely stopped using mercury. In fact, they actively avoid its use, and when appropriate, they remove old mercury fillings for patients. They practice mercury-safe dentistry. What does that mean, and why is this mindset so important? Continue reading to find out.

Mercury Is Toxic

Mercury is known to be a toxic material. It can harm the central nervous system, damage the brain and kidneys, and harm the body’s ability to fight oxidative stress.

Of course, it is important to keep in mind that in old dental fillings, the mercury is bonded to other materials, which stabilizes it. Therefore, individuals with amalgam restorations are not exposed to large amounts of it. However, some people do develop symptoms, especially if they have a lot of old fillings. This can occur because the fillings emit small amounts of mercury vapor that are easily inhaled.

Mercury-Safe Dentistry Uses Biocompatible Materials

When something is biocompatible, that means it works well within the human body and is not likely to cause any bad health effects. Thankfully, biocompatible filling materials are now widely available, and most dentists use them. For example, tooth-colored fillings are made of a composite resin that is completely free of all metals, including mercury.

These fillings not only look better than their old counterparts, but they bind more securely to the tooth structure and are less likely to leak. Plus, unlike metal, they do not stress the surrounding dentition by expanding and contracting in response to temperature changes.

Safety is Important During Mercury Removal

If your old fillings are in poor condition, or you wish to have them removed due to concerns about mercury toxicity, talk to your dentist and ask what precautions they use during the removal process. A lot of vapors can escape when old fillings are being removed, so precautions like a rubber dam to isolate the tooth, as well as the use of oxygen, can do a lot to protect both you as a patient and your dental team.

Mercury no longer has a rightful place in dentistry! Choose a dentist who avoids this material and focuses on your long-term oral and overall health.
