When most people think about cavity fillings, they picture that silver material that used to be so common. That’s a metal cavity filling. While newer materials like tooth-colored options are often used today, there are still some good reasons metal fillings haven’t completely disappeared from dentist offices. They can still be a solid way to treat certain kinds of tooth damage, especially for back teeth.
We’ll walk through what metal cavity fillings really are, why they’re still used in Maple Ridge and elsewhere, and when a different type of filling might be the better fit.
What Is a Metal Cavity Filling?
Cavities happen when tooth enamel breaks down, often from plaque or bacteria, and creates a small hole in the tooth. To fix it, we clean the area and fill that space with a strong material. This strengthens the tooth again and protects it from further damage.
One type of common filling material is called amalgam. It’s made from a mix of metals like silver, tin, copper, and liquid mercury. When these are blended in the right way, the material becomes firm and long-lasting.
Here’s how a metal filling is usually placed:
1. The damaged part of the tooth is cleaned out to remove decay
2. The area is shaped so the filling fits securely
3. The metal mixture is packed in and shaped to match your bite
4. Once it hardens, your tooth can handle chewing again
Amalgam fillings have been used for over a hundred years. Their strength and staying power are parts of why they’re still an option, especially where pressure from chewing is strongest.
At Kanaka Creek Family Dental, we offer traditional amalgam fillings for patients who want strength and reliability, particularly for molars that take the brunt of chewing force.
Reasons Metal Fillings Are Still Used Today
Even with modern options available, there are certain times when a metal filling makes the most sense. One reason is durability. Molars and other back teeth do a lot of tough work when we bite and chew. For those spots, something that can stand up to pressure is helpful.
A metal filling can handle:
• Bigger cavities that need more support
• Hard-to-reach areas where placing other materials is tricky
• Places where appearance isn’t a big concern, like the back of the mouth
Since metal doesn’t wear down as quickly in certain cases, it can be the right fit when we’re trying to repair a tooth in one of your main chewing spots. These fillings set quickly and don’t crack as easily under repeated strain. That means they can hold up to years of biting and chewing without shifting or breaking apart too soon.
Metal fillings remain a reliable option, especially for patients who need a cost-effective and durable treatment for teeth in the back of the mouth.
Are Metal Fillings Safe?
One common question we hear is about safety. Since metal cavity fillings contain mercury, it makes sense that some people are cautious. The mercury in these fillings is bound with other metals to create a stable material that’s been used and studied for decades.
Used safely across the world, metal fillings are monitored and tested by dental organizations to make sure they meet safety standards. If there were concerns about health risks, these fillings wouldn’t still be allowed.
As dentists, we always consider where the cavity is, how big it is, and what materials would work best for each situation. If a filling is going into a spot with heavy chewing or where a long-lasting fix is needed, a metal option might make sense. We always talk through the pros and cons with patients before getting started.
When a Different Filling Might Be the Better Option
Just because metal fillings work well in some situations doesn’t mean they’re the right match for every tooth. Many people prefer something that blends in better with their natural teeth, especially when the cavity is near the front.
Some common alternatives include:
• Composite resin (tooth-colored material that looks more natural)
• Ceramic or porcelain fillings
• Glass ionomer (used sometimes on baby teeth or around the gumline)
Appearance is one of the biggest reasons we suggest another material. Front teeth, or any tooth you see when you smile, usually benefit from something that matches your natural color. These alternatives may not last as long in heavy-biting zones, but they can be a good fit for teeth that don’t carry as much chewing force.
We also think about how much of the tooth needs fixing. Smaller fillings tend to do well with other materials. If the filling is large or deep, metal could still be the better call.
At Kanaka Creek Family Dental, we offer both metal and tooth-colored fillings, tailoring our recommendations to each patient’s unique needs and smile goals.

Metal cavity fillings are still around for a reason. They last a long time, especially in the back of the mouth where chewing pressure is strong. Their strength makes them a solid choice for certain dental repairs, even now.
