Tooth-Colored Composite Fillings in London, Ontario

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.

What Are Composite Fillings?

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.

Why We Use Composite Over Metal

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.

What Are Fillings Used For?

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.

How to Know If You Need a Filling

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:

What to Expect During a Composite Filling Appointment

Getting a filling at Luka Dental Care is a quick and comfortable experience. Here’s how the process works:

01
Gentle Numbing

We apply local anesthesia to the area to ensure you don’t feel any pain during the procedure.

02
Decay Removal

We gently remove the decayed portion of the tooth using precise instruments.

03
Tooth Preparation

We clean and shape the cavity to prepare it for bonding.

04
Filling Placement

The composite resin is layered into the cavity and hardened using a special curing light.

05
Shaping & Polishing

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.

Preventing Future Cavities

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.

Replacing Old Fillings

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.

When Composite Isn’t the Right Choice

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:

The decay is too extensive for a filling to support the tooth

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.

I had a silver filling from years ago that started to break down. Dr. Luka replaced it with a tooth-colored one, and it looks so natural I can’t even tell which tooth it was! The appointment was quick and totally painless.

Composite Fillings FAQs

How long do composite fillings last?

On average, 7 to 10 years—but with good brushing, flossing, and regular checkups, they can last even longer.

Are composite fillings safe?

Yes. They are biocompatible, free of mercury, and have been used successfully in dentistry for decades.

Do fillings hurt?

We use local anesthetic to numb the area, and most patients feel little to no discomfort during or after the procedure.

Can I replace my metal fillings with composite?

Yes! Many patients choose to replace old silver fillings for aesthetic reasons or due to wear. We’ll let you know if yours should be upgraded.

Do composite fillings stain?

They’re more stain-resistant than natural enamel but can darken slightly over time with exposure to coffee, tea, or smoking.

Can I eat right after my filling?

Yes. Composite fillings are cured instantly with light. You can eat as soon as the numbing wears off—though we recommend starting with soft foods.

Is it normal for a filling to feel sensitive afterward?

Yes, some sensitivity to pressure or temperature is common for a few days, especially if the cavity was deep. It should fade within a week or two. If not, let us know so we can check the bite or consider other solutions.

How do I know if my old filling needs to be replaced?

You may notice sensitivity, roughness, discoloration, or a feeling that something is off. But the most reliable way is to visit us for a checkup—we can assess it with visual inspection, X-rays, and testing.

Can fillings fall out?

It’s rare, but it can happen if the bonding fails or the tooth fractures. If a filling comes loose or falls out, call us as soon as possible so we can restore the tooth and prevent further damage.
