Cavities are one of the most common dental problems, but thanks to modern materials, fixing them doesn’t mean compromising the look of your smile. At Luka Dental Care in London, ON, we use natural-looking composite fillings that blend in seamlessly with your teeth while restoring strength and function.
Whether you’ve just discovered a new cavity or need to replace an old silver filling, we’ll make the process comfortable, efficient, and customized to your needs.
Composite fillings are tooth-colored restorations used to treat small to medium areas of decay. Made from a blend of resin and finely ground glass, these fillings are designed to match the natural shade of your enamel, making them practically invisible once placed.
They’re an excellent alternative to traditional silver (amalgam) fillings, especially for patients who want a more aesthetic option or are concerned about metal in their mouths.
While amalgam fillings were once the gold standard, composite materials have come a long way. Today’s composites are durable, versatile, and much more attractive.
Benefits of composite fillings:
Blends in naturally with your existing tooth structure
Preserves more healthy tooth during placement
Bonds directly to the tooth, adding strength and support
Mercury-free and metal-free
Ideal for front and back teeth
Because composite fillings bond chemically to your enamel, they often require less drilling than amalgam fillings. That means more of your natural tooth stays intact—and you get a restoration that functions well and looks great.
Fillings are primarily used to treat cavities, but they also serve several other restorative purposes. At Luka Dental Care in London, ON, we may recommend a composite filling for:
Treating tooth decay caused by bacteria and plaque
Repairing chipped or worn teeth
Reshaping a misshapen tooth for cosmetic reasons
Replacing old or cracked metal fillings
Sealing a minor crack or fracture
No matter the reason, composite material allows us to restore form and function while keeping your smile looking natural.
Not all cavities cause pain—some can exist for months without noticeable symptoms. That’s why regular checkups at our London dental office are so important. During your visit, we’ll use digital X-rays and intraoral imaging to look for any signs of decay or damage that may not be visible to the eye.
You might need a filling if you experience:
Getting a filling at Luka Dental Care is a quick and comfortable experience. Here’s how the process works:
We apply local anesthesia to the area to ensure you don’t feel any pain during the procedure.
We gently remove the decayed portion of the tooth using precise instruments.
We clean and shape the cavity to prepare it for bonding.
The composite resin is layered into the cavity and hardened using a special curing light.
We sculpt and polish the filling so it feels smooth and matches your bite.
Most fillings are completed in under an hour, and you can return to your normal routine immediately afterward.
Composite fillings do more than just “fill” a cavity—they restore the integrity of your tooth in a way that’s functional, comfortable, and cosmetically appealing.

Composite fillings are a great solution for existing decay—but prevention is always better. We’ll equip you with practical habits to lower your cavity risk: brush twice daily with fluoride toothpaste, floss every day, limit sugary drinks and snacks, book professional exams and cleanings every six months, and consider fluoride treatments or sealants if you’re prone to decay.
The better your daily routine, the fewer fillings you’ll need—and the longer your restorations will last.
Over time, even the most durable dental materials can begin to wear down. Metal fillings may corrode or develop microscopic cracks, allowing bacteria to seep underneath and cause hidden decay.
At Luka Dental Care in London, we carefully assess your existing fillings for signs of marginal breakdown, recurrent decay, tooth discoloration or sensitivity, and surface cracks or structural damage. Identifying these issues early can help prevent more serious problems down the line.
If replacement is needed, we’ll remove the old material and restore the tooth with a modern composite filling that’s safer, stronger, and far more natural-looking. It’s a simple upgrade that can make a big difference in both your oral health and your confidence.
While composite fillings are ideal for most cases, they’re not always the best solution. In some situations—like very large cavities or teeth that bear heavy biting forces—we may recommend an alternative, such as an inlay, onlay, or dental crown.
We might suggest something other than composite if:
In every case, we’ll walk you through your options and help you choose the solution that offers the best balance of durability, aesthetics, and long-term health.
