What Are Silver Fillings?

Silver fillings, also known as dental amalgam fillings, have been used for over a century to restore teeth that have decayed. Despite the name, these fillings are a mixture of several metals, including silver, tin, copper, and mercury. They’ve been preferred historically for their strength, longevity, and affordability, especially for molars that endure heavy chewing forces.

However, as dentistry evolves, patients today are more aware of aesthetics and long-term biocompatibility. That’s where concerns about silver fillings—and the mercury they contain—come into the spotlight.

Is the Mercury in Silver Fillings Harmful?

This is one of the most common concerns we hear at our dental clinics in Trivandrum.

While it’s true that silver fillings contain mercury, the form used is elemental mercury, which is bound with other metals to form a stable, non-reactive compound. Major dental and health organisations, including the American Dental Association (ADA) and World Health Organisation (WHO), have deemed them safe for use in most patients. Extensive studies have not found a reliable link between silver fillings and severe health conditions, such as Alzheimer’s disease or organ damage, especially when the fillings are intact and well-maintained.

However, damaged or old silver fillings can release small amounts of mercury vapour, particularly during chewing or teeth grinding. That’s why regular dental check-ups are essential, and if replacement is needed, it should only be done by a trained dental professional.

When Can Silver Fillings Become a Problem?

Silver fillings are strong but not indestructible. Over time, they can:

At Chitra MultiSpeciality Dental Clinic, we conduct routine examinations to assess the integrity of old fillings. If your filling is intact and you’re not experiencing sensitivity or decay underneath, we may advise you to keep it. However, if there is any sign of wear, damage, or decay, our expert team will recommend the best course of action.

Drawbacks of Silver Fillings

While functionally reliable, silver fillings come with several disadvantages:

1. Aesthetic Concerns

Silver fillings are visible, especially when you smile or laugh. In today’s age of high-definition photos and video calls, many patients prefer fillings that blend seamlessly with their natural teeth.

2. Metal Sensitivity and Cracks

Some patients may develop sensitivity to metals, and the rigid nature of amalgam can stress the tooth, sometimes causing cracks.

3. Not Eco-Friendly

There’s an environmental angle, too—mercury from dental offices, if not disposed of properly, can contribute to ecological mercury pollution.

Modern, Aesthetic Alternatives to Silver Fillings

Thanks to advances in dental materials, you now have safer, stronger, and more beautiful alternatives.

1. Composite Fillings

These tooth-coloured fillings are made from a resin-based material that bonds directly to the tooth. Perfect for visible teeth, composite fillings in Trivandrum are a popular choice at our clinic.

2. Ceramic (Porcelain) Fillings

Durable and stain-resistant, ceramic inlays or onlays are ideal for larger cavities or for patients seeking long-lasting, aesthetically pleasing solutions.

3. Glass Ionomer Cement

A great option for children and non-load-bearing areas, this material releases fluoride to protect the tooth from further decay.

4. Gold Fillings

Although not used as commonly today due to cost and aesthetic considerations, gold remains an excellent material for some instances where durability is crucial.

Should You Replace Your Silver Fillings?

At Chitra Dental, we advise patients not to remove their silver fillings just for the sake of it. If a filling is intact, functioning, and you're not experiencing any discomfort, there's usually no reason to replace it.

However, you should consult a dentist if:

Replacing silver fillings must be done with extreme care to avoid exposure to mercury vapour. Our clinic adheres to all recommended safety protocols, including the use of high-volume suction, rubber dam isolation, and the proper use of protective equipment.
