Dental fillings have been a fundamental part of dentistry for decades, providing a reliable solution for repairing cavities and restoring damaged teeth. However, discussions surrounding the use of mercury in dental fillings have sparked concerns and misconceptions. In this blog, we aim to separate facts from fiction, providing accurate information about mercury in dental fillings. If you’re considering dental fillings near you in London, Ontario, it’s essential to make informed decisions about your oral health.

Understanding Dental Fillings:

Dental fillings, often composed of a mixture of metals, have been used to treat cavities and tooth decay effectively. One common type, dental amalgam, contains a blend of metals such as silver, tin, copper, and mercury. Mercury, in particular, has been a topic of debate regarding its safety in dental restorations.

Facts About Mercury in Dental Fillings:

1. Dental Amalgam’s Safety Record: Dental amalgam has been used for over 150 years, and extensive research supports its safety and effectiveness. Various health organizations, including the World Health Organization (WHO) and the American Dental Association (ADA), have deemed dental amalgam a safe and durable material for dental restorations.
2. Low Mercury Vapor Release: While dental amalgam contains mercury, the amount released in vapor form is minimal and considered safe for patients. The ADA states that the exposure to mercury vapor from dental fillings is significantly lower than other daily sources of mercury, such as food and the environment.
3. Beneficial for Certain Dental Restorations: Dental amalgam is known for its durability, making it particularly suitable for restoring posterior teeth subjected to intense chewing forces. Its strength and longevity contribute to its continued use in specific clinical situations.

Fiction and Common Misconceptions:

1. Mercury Poisoning from Fillings: There is a common misconception that dental fillings can cause mercury poisoning. Extensive scientific studies have consistently shown that the levels of mercury released from dental amalgam restorations are well below the threshold for causing harm.
2. Effectiveness of Alternative Materials: While alternative materials exist, such as composite resin fillings, they may not be as durable in certain situations. It’s crucial to consult with your dentist in London, Ontario, to determine the most appropriate material for your specific dental needs.
3. Mandatory Removal of Amalgam Fillings: There is no consensus within the dental community regarding the mandatory removal of amalgam fillings solely due to the presence of mercury. The decision to replace existing amalgam fillings should be based on clinical considerations and individual patient needs.

Conclusion:

Choosing the right dental fillings is a decision that should be made based on accurate information and guidance from your dentist. If you’re in London, Ontario, and searching for “dental fillings near me,” rest assured that dental amalgam remains a safe and effective option for many patients. As with any dental treatment, open communication with your dentist is key to addressing concerns and making informed choices about your oral health.
