With advances in science and technology, more and more dentists are choosing to practice biocompatible dentistry. These practices include avoiding dental materials that could be harmful and removing existing restorations with these toxic properties.

Most of us have heard of the dangers related to mercury. Despite these warnings, mercury fillings were a low-cost alternative to gold restorations frequently used in the past. The prior belief was that the combination of silver with the mercury somehow leaves the filling safe, but this is not the case. Using mercury in dental amalgam fillings is harmful both to humans and the environment.

Amalgam removal is beneficial for many reasons with the most important being safety. Metal fillings prevent dentists from getting a closer look at the tooth, which masks any issues a patient might have in their mouth. By removing these fillings, the dentist will be able to prevent or treat any underlying problems such as decay. Without x-ray access to all of the patient’s teeth, the dentist won’t have a thorough understanding of their overall oral health.

Since amalgam fillings are large, it is likely that healthy parts of the tooth will have to be removed in order to hold it. Instead of destroying the tooth’s structure, composite fillings are a viable option that’s less invasive.Though the amalgam fillings themselves are rather durable, the surrounding teeth are not. From the expansion and contraction of the teeth, especially from hot and cold liquids, can cause the teeth to crack. Fractures are more likely in amalgam fillings than in those with any other material since they experience a wider degree or expansion and contraction. While the percentage is only around 1%, there is a population of people who are allergic to mercury and therefore could have a negative reaction to amalgam restorations.

Let’s be honest, old metal fillings are not only harmful, but they are unsightly as well. People with these fillings are more likely to feel self-conscious, especially if they have more than one. The metal doesn’t blend in with the surrounding teeth, making your smile look and feel unnatural. Replacing your old fillings with composite materials aesthetic allows for the work to blend in so that your smile is more aesthetically pleasing. Amalgam fillings can also create a greyish hue to your surrounding teeth, further discoloring your smile.

Dr. Brian Hee is a member of the International Academy of Oral Medicine and Toxicology (IAOMT), which is the “trusted Academy of medical, dental and research professionals who investigate and communicate safe science-based treatments to promote whole body health.” As an IAOMT dentist, his experience in the latest techniques of mercury removal combined with staying up to date in research deems him knowledgeable in the testing and detoxifying of mercury. Ultimately, amalgam fillings and restorations are harmful and outdated. There are other fill options available that are safer and aesthetically pleasing. Those patients with amalgam fillings should consider the benefits of having them removed, not only for their safety but to achieve that perfect smile as well.
