Restore teeth affected by cavities, minor cracks or wear with natural-looking dental fillings in Etobicoke. Our dental team uses tooth-coloured composite materials to restore the strength, function and appearance of your tooth while preserving as much healthy tooth structure as possible.
A tooth filling is a kind of dental restoration that is used in order to repair a tooth that has been damaged by decay, the damage being a cavity or a hole in the tooth’s structure.
During the early stages of tooth decay, the enamel might lose minerals, but this process can easily be stopped or reversed with fluoride and good oral care. However, if your tooth loses enough mineral that would cause an actual cavity, then the damaged tooth structure simply cannot grow back. The decayed portion in this case must be treated, and the space needs to be restored.
When a dentist wants to place a filling, they first examine the tooth to determine the extent of the decay. Depending on the tooth’s location and how severe the decay might be, the examination may include a visual examination, which is, of course, the standard procedure, sometimes dental instruments, and even, in some cases, an X-ray. After the examination, the decayed tooth tissue is removed, and it leaves a clean area that can quite easily be restored with filling material. The material replaces the part of the tooth that has just been removed, and it restores the tooth’s shape and function, which, of course, gives you back the ability to bite and chew with the previously decayed tooth as you used to!
Fillings can be done by using several materials.
The material that would be most appropriate for you heavily depends on factors such as the location and size of the cavity, the amount of remaining tooth structure, and, of course, your clinical needs.
Fillings are mostly used for cavities that are caused by tooth decay, but restorative materials are also sometimes used to repair certain areas of a damaged or lost tooth structure. They are mostly intended to preserve for you as much healthy natural tooth structure as possible whilst also restoring the area that has been affected by either tooth decay or tooth damage. However, a filling should not be your solution to every damaged tooth structure. For example, when the decay is really terminal and extensive and there is not enough healthy tooth structure left, a crown or another treatment (which your dentist is going to offer after sufficient examination) are usually more suitable approaches. And if the decay in the worst-case scenario reaches the pulp inside of your tooth and causes infection or significant damage, then you might need to get root canal treatment.
Since untreated decay can easily progress to an awful feeling of pain, an infection, or even tooth loss, you might need to treat that cavity as fast as you can while it is manageable and save yourself from the future pain that is going to be followed by it. And that is why we recommend regular dental examinations, since in these sessions decay can be detected rather easily, and it also helps your dentist to decide which kind of treatment would be the appropriate way to tackle this problem!
| # | Symptom / Sign | Decay Stage | Description & Mechanism | Recommended Action |
|---|---|---|---|---|
| 1 | Tooth Sensitivity | Deeper Layers | Sharp, uncomfortable sensation when consuming cold water, hot food, or sweet items (e.g., apple pie). Occurs as decay reaches deeper layers. | Schedule a dental checkup for examination & filling. |
| 2 | Toothache / Unexplained Pain | Moderate to Advanced | Unexplained pain, particularly noticeable or worsening while eating, indicating progress into inner tooth layers. | Book a dental examination as soon as possible. |
| 3 | White Spots | Early Stage (Enamel) | White or chalky-looking areas indicating initial mineral loss from enamel. A cavity hasn't formed yet. | Visit dentist for early evaluation (may revert via fluoride). |
| 4 | Brown, Black, or Dark Spots | Surface Discoloration | Discoloration on the tooth surface often associated with decay (though not every dark spot is a cavity). | Book a dentist appointment for proper diagnostic check. |
| 5 | Visible Hole or Pit | Established Cavity | A noticeable cavity or pit showing decay has progressed beyond early stages. Permanent structure loss. | Requires dental filling restoration as a solution. |
| 6 | Pain When Biting or Chewing | Varies / Structural | Sudden pain when chewing or grinding teeth. Can indicate decay, structural crack, or infection. | Quick appointment needed to diagnose exact cause. |
| 7 | Cavity Found on Exam / X-Ray | Asymptomatic / Hidden | Sneaky cavities developing between teeth or hard-to-see areas detected before any symptom appears. | Maintain routine dental exams & regular X-rays. |
Tooth-coloured composite fillings are made from a resin-based material that contains glass or sometimes other inorganic filler particles, as we have mentioned before. These composites are mainly used to restore teeth affected by cavities while maintaining a natural-looking appearance.
Conservative restoration: Composite restorations allow the dentist to preserve healthy tooth structure while restoring the damaged area.
Composite and amalgam are two established materials used to restore teeth affected by cavities. Composite fillings are tooth-coloured and made primarily from a resin matrix combined with inorganic filler particles, while dental amalgam is a metal alloy containing elemental mercury along with silver, tin and copper. Both can restore damaged tooth structure, but they differ considerably in appearance, placement, durability, cost and clinical indications.
| Criteria | Composite Fillings | Amalgam Fillings |
|---|---|---|
| Composition | Resin matrix combined with inorganic filler particles. | Metal alloy containing elemental mercury along with silver, tin, and copper. |
| Appearance & Aesthetics | Tooth-coloured. Matched to natural shade, making restorations considerably less noticeable. Ideal when smiling. | Silver-grey metallic. Does not match enamel; noticeable on front or visible teeth. |
| Tooth Preservation | Bonds adhesively to enamel and dentin. Allows removal of only damaged structure (conservative approach). | Does not bond adhesively. Requires mechanical retention, often removing more healthy tooth structure. |
| Strength & Durability | Modern composites perform well, but are technique-sensitive and more vulnerable under high chewing loads. | Strong and wear-resistant (150+ years of use). Ideal for large restorations in posterior teeth under heavy force. |
| Longevity Evidence | Well-placed composites achieve good long-term survival, though performance varies by cavity size/location. | 2025 systematic review showed greater median survival in posterior teeth; ADA notes no universal gap. |
| Moisture Sensitivity | High moisture sensitivity. Requires a reliable, dry working field for predictable bonding. | Less dependent on adhesive bonding; advantageous when moisture control is difficult. |
| Secondary Decay Risk | Some studies show higher secondary caries rates in posterior teeth (influenced by hygiene, diet, placement). | Historically lower rates of secondary decay in certain posterior clinical studies. Advantageous for high decay-risk patients. |
| Postoperative Sensitivity | Technique-sensitive; polymerization shrinkage during curing can cause interface stress/sensitivity if unmanaged. | Can also cause temporary postoperative sensitivity in certain clinical circumstances. |
| Placement Technique | Complex and time-consuming; requires isolation, adhesive bonding, incremental placement/curing, and polishing. | Comparatively less technique-sensitive regarding moisture; requires no adhesive bonding. |
| Cost | Generally higher cost due to technique sensitivity, specialized adhesives, and longer placement time. | Traditionally one of the least expensive direct restorative materials. Lower initial material cost. |
| Mercury & Health | Contains no mercury. No exposure risks. | Contains elemental mercury. FDA: Safe for general population, but recommends alternatives for high-risk groups. |
| Environmental Impact | Avoids mercury-related environmental concerns. | Subject to international environmental reduction efforts regarding mercury disposal. |
| Most Suitable When (Clinical Indications) |

A tooth filling is most of the time a pretty direct procedure that focuses on removing damaged tooth tissue and structure, whilst after that they restore the resulting area with filling material. Although the exact process is not something we can clearly foresee since it heavily depends on your tooth, the extent of its decay, and, of course, the material that would be used for the filling.
Your dentist is going to examine the affected tooth and its surrounding area in order to find signs of decay. They might use their dental instruments during this time and, if they deem it necessary, an X-ray in order to find the exact location and the extent of the cavity.
A local anesthetic will be used in order to numb your tooth and its surrounding tissues, so that you may be comfortable as your dentist treats your tooth.
Your dentist will remove the decayed tooth tissue with their specialized and highly reliable dental instruments. Dentists aim to preserve as much healthy tooth structure as possible while removing the decayed tissue necessary to restore the tooth effectively.
After everything, the cleaned area is filled with the restorative material that has been selected.
With composite resin, the material is bonded to the tooth and hardened using a curing light.
Lastly, your dentist will shape and smooth the restoration until it follows the tooth’s natural contours. They will then check your bite in order to ensure that the restored tooth feels comfortable after the procedure.
Tooth fillings, of course, like beauty, do not last forever. Their lifespan varies according to things such as the filling material, the size and location of the restoration, your chewing force, and, obviously, your oral hygiene. So, that is why we get back to telling you, regular dental examinations can actually help a lot in identifying fillings that are either worn or damaged before they even try to cause problems for you.
Brush twice daily with fluoride toothpaste (our teacher used to say brush at night to keep your teeth white), clean between your teeth every day, either with a toothpick or with floss (we recommend the latter), cut off a bit on the sugar, less cake and ice cream, and you notice your fillings have not changed at all. Of course, last but not least, do not forget your regular dental visits.
Well, a dental filling is generally used when the areas of decay or damage are smaller, while a crown is actually designed to restore and protect a tooth that is in a way worse condition; it is more substantially weakened, broken, or decayed. To choose between the two, your choice must depend on how much healthy tooth structure is remaining and how bad the damage is.
As we have previously discussed, fillings aren’t eternal, and they can actually wear down, fracture, loosen, or develop decay around their edges. Your dentist can check an older restoration regarding these problems, and based on what they see, they can determine whether it should be repaired or replaced. Since replacing a filling can remove even more tooth structure, conservative repair is sometimes more appropriate when the damage is limited and not that bad.
Tooth fillings are mostly less extensive and less costly than major restorative procedures like dental crowns or root canal treatment. Although there is quite a difference witnessed in the procedure’s cost depending on the size and location of the cavity, the filling material used, and, last but not least, the complexity of the treatment. Your dentist can give you the estimate after they examine your teeth.
Many private dental insurance plans cover tooth fillings as a basic restorative service, although the extent of coverage and replacement limitations vary between policies. The Canadian Dental Care Plan (CDCP) also covers eligible fillings on permanent teeth, subject to its coverage rules and frequency limitations. You should confirm your individual benefits and any potential out-of-pocket costs with your insurance provider and dental office before treatment.

No, because your dentist will use local anesthesia in order to numb the area, so you won’t feel significant pain during the procedure. Although there will be a sense of mild sensitivity after the procedure, which is pretty common, and it’s usually temporary.
The good news is that most fillings can be completed in a single visit! The exact time, although, is not a fixed number, as it can vary based on the size and location of the cavity and the type of filling being placed.
Composite fillings can last for many years if you have good oral hygiene and do regular dental care. Their lifespan depends on factors such as the filling’s size and location, your chewing force, and, of course, as we have mentioned before, your oral hygiene.
Yes, but it would be better if you wait until the numbness has worn off, so that there wouldn’t be any unpleasant events like accidentally biting your cheek, lip, or tongue.
Yeah, composite fillings can be used on back teeth, but the most suitable material depends on the size, location, and condition of the tooth.
Yes, in many cases, your dentist will first examine the existing filling and the surrounding tooth in order to determine if replacing it with a tooth-coloured composite filling is appropriate.
Well, cavities do not always cause symptoms. But as we have covered in our article, they can have some symptoms like sensitivity, toothache, visible holes or pits, and pain when biting or chewing. Although some cavities that do not show any symptoms are only discovered during a dental examination or X-ray.
You wouldn’t want that to happen. An untreated cavity can continue to grow, and it will eventually cause pain, infection, or, in some bad cases, significant tooth damage. If the decay progresses, then more extensive treatments such as root canal treatment or even extraction may be needed.
The cost depends on factors such as the size and location of the cavity, the filling material, and the complexity of treatment. Your dentist can provide an estimate after examining the tooth.
Many dental insurance plans cover fillings as a basic restorative service, but coverage varies between plans. The CDCP also covers eligible restorative services, including fillings, subject to its coverage rules and limitations.
