How Much Do Dental Fillings Cost
The cost of a dental filling depends mainly on the material used, how many surfaces of the tooth are involved, which tooth is being treated, and whether extras such as X-rays or sedation are needed. Small, single-surface fillings cost the least, while large tooth-coloured fillings on back teeth and ceramic inlays cost more. Because every cavity is different, the only accurate figure comes from an exam, and our restorative dentistry team in Tillsonburg provides a clear estimate before treatment begins.
Filling fees are based on material, size measured in tooth surfaces, tooth location, and any additional procedures. In Ontario, dentists commonly reference the provincial dental association fee guide, and coverage from insurance, the Canadian Dental Care Plan (CDCP), or provincial programs can reduce what you pay.
Treating a cavity early is almost always the most economical choice. A small cavity needs a small filling. Left untreated, decay can spread, turning a simple filling into a root canal, crown, or extraction. In some cases, gentle techniques such as laser-assisted cavity treatment can reduce the need for drilling and anaesthetic.
Comfort is part of good care. If dental visits make you anxious, you can ask about sedation for routine dental work, which may be listed separately on your estimate.
Fillings are one part of keeping your teeth healthy. Regular checkups, cleanings, and X-rays are covered in our general dentistry services and help catch decay while it is still small.
What Is a Dental Filling?
A dental filling repairs a tooth damaged by decay, a small fracture, or wear. The dentist removes the decayed tissue, cleans the area, and fills the space with a restorative material to restore the tooth’s shape and function and prevent bacteria from re-entering.
Main Factors That Affect Filling Cost
1. Filling Material
Different materials involve different costs, techniques, and time in the chair.
2. Number of Surfaces
Teeth have several surfaces, such as the biting surface, the front, the back, and the sides between teeth. Fees typically increase with each additional surface the filling covers.
3. Tooth Location
Back teeth (molars and premolars) are larger and harder to access, and tooth-coloured fillings there take more time. Front teeth often need careful shade matching for appearance.
4. Cavity Depth
Deep cavities close to the nerve may need a protective liner or base, which can add to the procedure.
5. Diagnostic Records
X-rays and an exam are usually needed to diagnose the cavity and are billed separately.
6. Sedation or Additional Anaesthesia
Nitrous oxide or oral sedation for anxious patients adds to the total.
7. Insurance and Program Coverage
Your plan, annual maximums, and co-payments greatly influence your out-of-pocket amount.
Filling Materials Compared
| Material | Appearance | Durability | Relative cost |
|---|---|---|---|
| Amalgam (silver) | Visible metal colour | Very durable on back teeth | Usually lowest |
| Composite (tooth-coloured) | Natural, matches tooth shade | Durable, more technique sensitive | Moderate |
| Glass ionomer | Tooth-coloured, less translucent | Lower wear resistance | Low to moderate |
| Ceramic or porcelain inlay | Highly natural, stain resistant | Very durable | Higher |
| Gold inlay or onlay | Gold colour | Extremely durable | Highest |
How Insurance and Programs Affect What You Pay
Private Dental Insurance
Most workplace and private plans cover fillings as basic services, often at a set percentage up to an annual maximum. Some plans pay tooth-coloured fillings on back teeth only at the amalgam rate, meaning you pay the difference. Ask your dental office to submit a predetermination if you want to know your share in advance.
Canadian Dental Care Plan (CDCP)
The CDCP covers fillings as part of its basic services for eligible Canadians without dental insurance. Depending on family income, some patients pay a co-payment. Coverage details for specific materials can vary, so the clinic can check your eligibility and benefits before treatment.
Healthy Smiles Ontario
This provincial program covers dental care, including fillings, for eligible children and youth 17 and under from low-income households.
ODSP and Ontario Works
Adult recipients typically have coverage for basic dental services such as fillings, subject to program rules.
Ontario Seniors Dental Care Program
Eligible low-income seniors aged 65 and over can receive basic dental care, including fillings, through participating providers.
| Coverage source | Fillings usually covered | Things to check |
|---|---|---|
| Private insurance | Yes, as basic services | Percentage, annual maximum, material downgrade |
| CDCP | Yes, for eligible patients | Co-payment level, material rules |
| Healthy Smiles Ontario | Yes, for eligible youth | Eligibility and enrolment |
| ODSP or Ontario Works | Yes, basic services | Program limits |
| Ontario Seniors Dental Care Program | Yes, for eligible seniors | Participating clinics |
Why Fees Vary Between Clinics
Even for the same filling, quotes can differ. Reasons include:
- Clinic location and operating costs
- The brand and quality of materials used
- Technology such as digital X-rays, magnification, and isolation systems
- Time spent on shade matching, layering, and polishing tooth-coloured fillings
- Whether the dentist follows or adjusts the provincial fee guide
A slightly higher fee that includes careful technique and quality materials can mean a filling lasts longer and needs fewer repairs.
Step by Step: What Is Included in a Filling Visit
- Exam and diagnosis. The dentist confirms the cavity visually and with X-rays.
- Estimate and consent. You receive a breakdown of the procedure, material options, and expected coverage.
- Local anaesthetic. The area is numbed for comfort.
- Decay removal. Damaged tissue is removed and the tooth is cleaned.
- Placement. The filling material is placed, shaped, and hardened if it is composite.
- Bite check and polish. The filling is adjusted so your teeth meet evenly.
- Aftercare advice. You learn when you can eat and how to care for the tooth.
Ways to Keep Filling Costs Manageable

Use your benefits
Schedule care within your benefit year to use available coverage.
Ask for predetermination
Know your share before treatment begins.
Discuss material options
Your dentist can explain the pros and cons of each choice.
Prevent new cavities
Fluoride, sealants, and lower sugar intake reduce future fillings.
Myths About Filling Costs
How Long Do Fillings Last?
Lifespan affects long-term value. Amalgam fillings often last many years on back teeth. Composite fillings also last many years with good care, though large ones in heavy-bite areas may need replacing sooner. Ceramic and gold restorations are typically the longest lasting. Brushing, flossing, limiting sugary snacks, and wearing a night guard if you grind all help fillings last.
When a Filling May Not Be Enough
If a cavity is very large or the tooth is cracked, a filling alone may not hold. Your dentist may suggest an inlay, onlay, or crown for strength. If decay reaches the nerve, root canal treatment may be needed first. These options cost more, which is another reason early treatment is worthwhile.
Understanding Your Filling Estimate
A written estimate can look technical. Here is what the common items usually mean:
- Examination: a recall, specific, or emergency exam to assess the problem
- Radiographs: bitewing or periapical X-rays used to see decay between teeth or near the root
- Restoration code: describes the material and number of surfaces, for example a two-surface composite on a molar
- Anaesthetic or sedation: listed separately when sedation is used
- Laboratory fees: apply to inlays and onlays made outside the office
If anything is unclear, ask the front desk to walk you through it. Knowing exactly what each line covers helps you compare estimates and plan your budget confidently.
Fillings for Children
Children’s fillings follow the same principles but may involve baby teeth that will eventually fall out. Your dentist will consider how long the tooth needs to last before recommending a material. Glass ionomer or composite is common for children, and sealants on molars can prevent many cavities from forming. Programs such as Healthy Smiles Ontario and the CDCP may cover eligible children’s care.
Fillings and Overall Oral Health
A filling stops decay at that spot, but it does not prevent new cavities elsewhere. Reducing sugary drinks, brushing with fluoride toothpaste, and cleaning between teeth every day are the most effective ways to avoid repeat treatment. Your dentist may also recommend fluoride varnish if you are prone to cavities.

Frequently Asked Questions
Why do filling prices vary so much?
Fees depend on the material, number of tooth surfaces, tooth location, cavity depth, and any extras such as X-rays or sedation.
Are white fillings more expensive than silver fillings?
Tooth-coloured composite fillings usually cost more than amalgam because they take more time and technique to place.
Does the CDCP cover dental fillings?
Yes, fillings are included in CDCP basic services for eligible patients. Some patients pay a co-payment based on family income.
Does insurance cover tooth-coloured fillings on back teeth?
Some plans pay only the amalgam rate for back teeth, so you may pay the difference. Ask your clinic to check your plan.
Is it worth replacing old fillings?
Only if they are cracked, leaking, decayed underneath, or causing problems. Your dentist will advise if replacement is needed.
Conclusion
The cost of a dental filling depends on the material, size, location, and your coverage. Treating cavities early keeps fillings small, simple, and more affordable. A dental exam is the best way to get an accurate estimate and protect your tooth.
