When you hear the words “you have a cavity,” the next step usually involves getting a filling. But with so many options available, it’s natural to wonder what materials are used—and more importantly, whether they’re safe.
At Smiles On Tomken, one of the most common questions we hear from patients is: “Are composite fillings safe?”
The short answer is yes, composite fillings are safe and widely used in modern dentistry. In fact, they’re one of the most popular choices for restoring decayed or damaged teeth—not only because of their safety but also for their aesthetic benefits.
Let’s take a closer look at what composite fillings are, how they compare to other materials, and why they’re considered a safe and effective solution.
What Are Composite Fillings?
Composite fillings—also known as tooth-coloured fillings—are made from a mixture of resin (plastic) and glass or ceramic particles. This combination creates a strong, durable material that closely matches the natural colour of your teeth. As a result, composite fillings blend in seamlessly with your smile, making them a great option for both front and back teeth.
They are used to:
- Repair cavities
- Fix chipped or broken teeth
- Close gaps between teeth
- Reshape teeth for cosmetic purposes
Are Composite Fillings Safe?
Yes, composite fillings are considered safe by dental professionals and major health organizations, including the Canadian Dental Association (CDA) and the American Dental Association (ADA).
Here are a few reasons why they’re considered safe:
-
Mercury-Free Material
Unlike traditional silver (amalgam) fillings, composite fillings contain no mercury. This is a big reason why many patients—and dentists—prefer them. Although amalgam fillings are still considered safe by many authorities, some individuals choose to avoid mercury for personal health and environmental reasons.
-
Biocompatibility
Composite materials are biocompatible, meaning they are generally well-tolerated by the body. Allergic reactions are extremely rare, but if you have known sensitivities or health concerns, our team at Smiles On Tomken can help assess what’s best for your needs.
-
Safe for All Ages
Composite fillings are safe for children, teens, adults, and seniors. In fact, they are often the preferred choice for pediatric dental care because they are less noticeable and require less tooth removal.
Benefits of Composite Fillings
Beyond safety, composite fillings offer several benefits that make them an attractive option for patients seeking both form and function.
✔ Natural Appearance
The biggest advantage of composite fillings is that they match your natural tooth colour, making them ideal for visible areas of your mouth. Once placed, they are virtually invisible.
✔ Minimally Invasive
Composite resin bonds directly to your tooth, allowing for a more conservative treatment. Less drilling means more of your natural tooth is preserved.
✔ Versatile Use
Composite material can be used not only for fillings but also for cosmetic improvements like reshaping teeth or repairing chips.
✔ Strong and Durable
Modern composites are durable and can last many years, especially with good oral hygiene and regular dental checkups.
Are There Any Downsides?
Like all dental materials, composite fillings have a few limitations to consider:
- Slightly Less Durable Than Amalgam: In some cases—particularly with large fillings in back molars—composite may wear faster than metal. However, advances in material technology have greatly improved their strength.
- Slightly More Expensive: Composite fillings may cost a bit more than amalgam, but many patients find the natural look well worth the difference.
- Technique-Sensitive: Proper placement requires a dry field and more time, which is why it’s important to have them done by an experienced dental team—like ours at Smiles On Tomken.
How Long Do Composite Fillings Last?
With proper care, composite fillings can last 7 to 10 years or more. Factors like oral hygiene, diet, teeth grinding, and the size of the filling can affect longevity. Regular checkups help monitor your fillings and ensure they’re holding up well.
What Happens During a Composite Filling Procedure?
Getting a composite filling is a straightforward process. Here’s what to expect at Smiles On Tomken:
- Numbing the Area: Local anesthesia is used to keep you comfortable.
- Removing Decay: The damaged part of the tooth is carefully cleaned out.
- Placing the Filling: Composite resin is applied in layers, cured with a special light, then shaped and polished to match your tooth.
- Bite Adjustment: We check your bite and make adjustments so your teeth come together comfortably.
You can eat and drink shortly after the procedure, although we recommend waiting until the numbness wears off completely.

Composite fillings are a safe, attractive, and reliable solution for treating cavities and restoring damaged teeth. They provide excellent performance and blend in beautifully with your natural teeth—without the use of metals or mercury.
