A tooth filling repairs a cavity or a small chip, so the tooth is strong and comfortable again. At Luka Dental Care on Aldersbrook Road in London, Ontario, we fill teeth for kids and adults with tooth-colored composite that matches your smile.
Not every cavity is a small filling away from being fixed. When decay reaches the nerve, endodontic treatment can save the tooth before it needs to be pulled. For larger cavities or fractured teeth that fillings can't fully restore, dental crowns provide full coverage and protection. And if a tooth has already been lost, fixed bridges or denture options can replace it without leaving a gap.
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 bonds to your enamel, it often needs less drilling than a metal filling. More of your natural tooth is saved, and the filling looks like part of the tooth.
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 hurt, and some cause no signs for months. That is why regular checkups at our London office help. We use digital X-rays and an intraoral camera to find decay you cannot see.
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 numb the area with local anesthesia, so you do not feel pain during the filling.
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 fill a hole. They make the tooth strong again, and they look and feel natural.

A filling fixes decay you already have, but stopping the next cavity is even better. Brush twice a day with fluoride toothpaste, floss every day and cut back on sugary drinks and snacks. Come in for an exam and cleaning every six months, and ask us about fluoride or sealants if you get cavities often.
The better your daily routine, the fewer fillings you will need, and the longer your fillings 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.
Composite fillings work well for most cavities, but not all of them. For a large cavity or a back tooth that takes heavy biting, we may suggest an inlay, an onlay or a 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.
The cost of a filling depends on your tooth, so we do not quote one price for everyone. Here is what changes the price:
The size of the cavity
A small filling on one side of a tooth costs less than a large one that covers two or three sides.
Which tooth it is
Fillings on back teeth often take more work than fillings on front teeth.
The filling material
We use tooth-colored composite. Insurance plans differ in how they pay for it, so it is worth asking yours.
Your insurance plan
Many plans pay for part of a filling. We look at your benefits with you before we begin.
Before we start, we tell you the cost of each step. For a closer look at prices, read how much a tooth filling costs without insurance in Ontario. If you have the Canadian Dental Care Plan, our CDCP dentist in London, Ontario page explains what it covers.

Often 7 to 10 years, and with good brushing, flossing and regular checkups they can last even longer.
Yes. They are biocompatible, free of mercury, and have been used successfully in dentistry for decades.
We use local anesthetic to numb the area, and most patients feel little to no discomfort during or after the procedure.
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.
They’re more stain-resistant than natural enamel but can darken slightly over time with exposure to coffee, tea, or smoking.
Yes. Composite fillings are hardened with a light right away, so you can eat once the numbing wears off. Start with soft foods at first.
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.
You may notice sensitivity, rough edges, a dark color or a feeling that something is off. The best way to know is a checkup, where we look at it and take X-rays if needed.
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.
It depends on how big the cavity is, which tooth it is and what your insurance plan pays. After an exam, we tell you the cost before we start.
