Say Goodbye to Metal Mouth—Hello to Seamless Smiles!
Gone are the days when silver fillings were the only option for repairing cavities. At MI Dental in Kitchener, we offer tooth-colored composite fillings that blend seamlessly with your natural teeth. Strong, safe, and virtually invisible, these restorations restore both the function and beauty of your smile.
A Brief History of Fillings
For more than a century, amalgam (silver) fillings were the gold standard of restorative dentistry. They were inexpensive, long-lasting, and easy to place, which is why millions of patients around the world still have them today. However, their metallic color made them highly visible, and patients increasingly wanted a more natural-looking alternative.
Advances in dental science during the late 20th century gave us the solution: composite resins—a tooth-colored material that could restore cavities while blending in perfectly with the surrounding enamel.
What Makes Composite Resins Special?
Composite resins are made from a blend of plastic matrix and finely ground glass particles, giving them unique properties:
- Aesthetics: They mimic the natural translucency and shade of real teeth, making them nearly impossible to detect.
- Strength: When bonded to your enamel, they reinforce the remaining tooth structure, helping prevent cracks and fractures.
- Durability: With proper care, bonded fillings can last many years, offering an excellent balance between beauty and resilience.
- Precision: Because they bond directly to tooth surfaces, less drilling is required compared to older materials—allowing us to preserve more healthy enamel.
Beyond Dentistry: Composite Resins in Other Industries
The strength and versatility of composite resins extend far beyond dentistry. They are widely used in aviation, aerospace, and automotive industries, where lightweight but durable materials are critical. Airplane fuselages, racing car panels, and even sports equipment like tennis rackets and golf clubs often rely on composite technology.
This cross-industry use underscores just how reliable these materials are—if they can withstand the stresses of flight and high-speed racing, they are more than capable of holding up in the human mouth!
How Composite Fillings Are Placed
One of the most fascinating aspects of bonded fillings is the way they are applied. Unlike silver amalgam, which was packed directly into a cavity, composites are placed in a moldable, gel-like form. Your dentist sculpts the material carefully to replicate the natural curves and anatomy of your tooth. Once the shape is perfected, a special blue curing light hardens the resin within seconds, locking it into place. The final step involves polishing the filling to a smooth, glossy finish so it blends invisibly with your smile.
Fun Fact
Did you know that dental composites are color-matched with a shade guide—a chart of tiny enamel-colored tabs? Dentists hold these up to your teeth to choose the perfect match, like picking a paint swatch at the hardware store—but far more precise!
FAQs About Bonded Fillings
1. How long do composite fillings last?
On average, 7–15 years, depending on the size of the filling, your oral hygiene, and habits like grinding or chewing hard objects.
2. Are composite fillings as strong as silver amalgam?
Yes—while amalgam may last longer in certain high-stress situations, modern composites are highly durable, bond directly to enamel, and reinforce the tooth structure.
3. Do composite fillings cost more?
They are typically more expensive than amalgam due to the material and technique involved, but most patients find the aesthetic and health benefits worth the investment.
4. Will people notice my fillings?
Not at all. Composite fillings are color-matched to your natural enamel and polished for a seamless finish. Most patients can’t even tell where the filling begins and the natural tooth ends.
5. Can old silver fillings be replaced with composites?
Yes—if your amalgam fillings are cracked, leaking, or simply bothersome aesthetically, we can replace them with tooth-colored composites for a more natural look.
