For decades, silver fillings — known as dental amalgam — were the standard for treating cavities. If you had a cavity filled in the 80s, 90s, or even early 2000s, chances are it was done with amalgam.
But in recent years, many Canadians are wondering: Are silver fillings still used today? Let’s take a closer look at how dental practices have evolved — and whether amalgam is still part of modern dentistry in Canada.
🦷 What Are Silver Fillings Made Of?
Silver fillings are made from dental amalgam, a mixture of metals that includes:
- Silver
- Mercury
- Tin
- Copper
- Sometimes small amounts of zinc or other metals
Despite the name, mercury makes up about 50% of the compound. When combined with the other metals, the mercury is stabilized and forms a durable, long-lasting material.
✅ Are Silver Fillings Still Used in Canada?
Yes — but far less commonly than in the past.
While amalgam is still approved and available for use in Canada, most dental clinics now prefer tooth-coloured composite fillings, especially for visible areas like front teeth or smile lines.
In fact, many Canadian dental practices have moved away from amalgam altogether due to:
- Aesthetic concerns — patients prefer white fillings that blend in
- Environmental considerations — disposal of mercury-containing materials is regulated
- Advancements in composite materials — which are now much stronger and more durable than they used to be
That said, silver fillings are still used in specific cases — especially for back molars, patients with high cavity risk, or where cost is a concern and strength is a top priority.
🔎 Are Silver Fillings Safe?
Yes. According to Health Canada and the Canadian Dental Association, amalgam fillings are considered safe for most people. The mercury in the filling is bound within the compound and does not pose a health risk under normal conditions.
However, amalgam is generally not recommended for:
- Pregnant or breastfeeding individuals
- People with mercury allergies or sensitivities
- Patients with certain kidney conditions
If you already have silver fillings and they’re in good shape, there’s no need to replace them unless there’s a specific dental reason (such as decay around the filling or cracks in the tooth).
🔄 Can You Replace Silver Fillings?
Absolutely. Many Canadians choose to replace older silver fillings with white composite fillings for cosmetic reasons — especially in visible areas of the mouth. Your dentist can assess whether this is a good option for you and whether the existing filling is still doing its job.
