The Dangers of Silver Mercury Fillings
Silver Mercury fillings, also commonly known as amalgam fillings, are dental fillings that consist of a mixture of mercury, silver, tin, and copper. The use of mercury in fillings has been controversial for many years, as it is a known neurotoxin that can potentially cause health problems.

Dr. Beata A. Carlson and Associates Natural Dentistry in Clearwater, Florida, works with patients to help them understand the dangers of silver-mercury fillings. They offer a safe way to replace existing silver -mercury fillings with a biocompatible option.
Despite the noted and definitive dangers of silver mercury fillings, they are still commonly used in the United States. According to the Centers for Disease Control and Prevention (CDC), about half of all Americans have at least one silver mercury filling. Patients who have these fillings ultimately must know the risks of having mercury in their bodies.
What are the risks of mercury or “silver amalgam” fillings?
There are several risks associated with silver-mercury fillings:
- Health problems. Primarily, mercury is a neurotoxin that can cause damage to the brain and nervous system. It can also cause other health problems such as kidney damage, respiratory problems, and heart problems.
- Mercury toxicity. Another concern with mercury fillings is releasing mercury into the body over time. This can happen when the filling cracks or when bacteria from the mouth eat away at the filler. Mercury can then be absorbed into the bloodstream and cause health problems. Mercury is also released from silver amalgam fillings when heated, which can occur with drinking hot beverages or friction while chewing food.
- Appearance. Silver amalgam fillings are not only harmful due to their materials, but they are also unattractive. Large fillings with mercury are dark in color and highly noticeable when patients are smiling, laughing, or talking with others.
What to do about silver mercury fillings
Because of the several disadvantages of silver mercury fillings, patients serious about their oral health and wellness will want to work with Dr. Beata A. Carlson and Associates at Natural Dentistry of Clearwater, Florida, to discuss possible alternatives. There are options for patients to consider, including placement composite resin fillings or even placing a dental crown over the compromised tooth. This is a more biocompatible way to restore and repair the tooth without harming toxic materials. Many patients come into our office to have their silver mercury fillings properly (and safely!) removed and replaced with composite resin alternatives or porcelain dental crowns. We maintain as much natural tooth structure as possible while ensuring suitable materials for patient health and a beautiful finished appearance.
