Dental fillings Ajax are a common and effective solution for treating cavities and restoring damaged teeth. If you’ve been told you need a cavity treated, you’re not alone. Tooth decay is one of the most common dental concerns for patients of all ages. At Ajax Aria Dentistry, many patients come in with questions about dental fillings Ajax, especially what the procedure involves and whether it will be uncomfortable.
Dental fillings are a simple and effective way to restore a tooth that has been damaged by decay. They help stop further damage, relieve sensitivity, and bring your tooth back to normal function so you can eat, speak, and smile comfortably again.
What Are Dental Fillings?
A dental filling is a treatment used to repair a tooth affected by cavities or minor damage. When decay forms, the damaged part of the tooth is removed and replaced with a filling material.
The goal is to restore strength and protect the tooth from further decay. Fillings are one of the most routine dental treatments and are often completed in a single visit.
Signs You May Need a Filling
Cavities don’t always cause pain right away, which is why regular checkups are important. However, there are some common signs that may indicate you need a filling:
- Tooth sensitivity to hot, cold, or sweet foods
- A visible dark spot or hole on the tooth
- Pain when chewing or biting
- Food getting stuck in a specific area
- Rough or chipped tooth surfaces
If you notice any of these symptoms, it’s a good idea to book an appointment as soon as possible. Early treatment can prevent more extensive dental work later on.
What Happens During a Dental Filling Appointment
Many patients feel nervous before their first filling, but the process is straightforward and typically comfortable.
Here’s what usually happens:
- The dentist examines your tooth and may take X-rays
- The area is numbed using a local anesthetic
- Decay is carefully removed from the tooth
- The cleaned space is filled with a suitable material
- The filling is shaped and polished for a natural bite
Most appointments take less than an hour, depending on the size and location of the cavity.

Types of Filling Materials
There are several types of materials used for fillings, and your dentist will recommend the best option based on the tooth and location.
Common options include:
- Composite resin: Tooth-coloured and blends naturally with your smile
- Amalgam: A durable silver-coloured material often used for back teeth
- Ceramic: Strong and natural-looking, often used for larger restorations
Each material has its benefits, and your dentist will help you choose the right one based on durability, appearance, and cost.
How Long Do Dental Fillings Last
The lifespan of a filling depends on the material used and your oral hygiene habits.
On average:
- Composite fillings last 5–10 years
- Amalgam fillings can last 10–15 years or longer
- Ceramic fillings often last 10–15 years with good care
Brushing twice daily, flossing, and attending regular dental checkups can help extend the life of your filling.
Dental Filling Recovery and Aftercare
After your appointment, it’s normal to experience mild sensitivity for a few days. This usually improves quickly as the tooth adjusts.
To care for your filling:
- Avoid very hot or cold foods immediately after treatment
- Chew on the opposite side if possible for the first day
- Maintain good brushing and flossing habits
- Use sensitivity toothpaste if needed
- Avoid hard or sticky foods if your tooth feels tender
If discomfort lasts more than a week, it’s best to contact your dentist for a follow-up.
How Much Do Dental Fillings Cost in Ajax
The cost of dental fillings in Ajax can vary depending on the size of the cavity, the material used, and the tooth location.
In general, patients can expect:
- Smaller fillings to cost less
- Larger or more complex fillings to cost more
- Tooth-coloured materials to be slightly higher in price than amalgam
Most dental insurance plans in Canada cover part or all of the cost of fillings, especially when they are medically necessary. It’s always a good idea to check your coverage before treatment.
Preventing Future Cavities
The best way to avoid needing fillings is prevention. Small daily habits can make a big difference in your oral health.
Here are some helpful tips:
- Brush your teeth twice a day using fluoride toothpaste
- Floss daily to remove plaque between teeth
- Limit sugary snacks and drinks
- Drink plenty of water throughout the day
- Visit your dentist regularly for cleanings and exams
Preventive care helps catch early signs of decay before they turn into larger problems.
When to Contact a Dentist
You should contact a dentist if you experience:
- Persistent tooth pain or sensitivity
- Visible holes or dark spots on teeth
- Broken or chipped teeth
- Pain while chewing
Even if symptoms seem mild, early treatment can prevent more serious dental issues and reduce the need for more extensive procedures.
