Why Do I Need To Pay When Am Covered 100% Under Dental Insurance?

Why You Still Have an Out-of-Pocket Cost Even With 100% Dental Insurance

If your dental plan says you are covered at 100% but you still received a bill after your appointment, the reason is straightforward: your insurer pays 100% of what they have decided a procedure is worth — not 100% of what your dentist actually charges. This gap between your insurance company’s internal fee schedule and your dental clinic’s fees is the most common reason patients across Calgary receive an unexpected balance owing. Understanding how this works will help you plan ahead and avoid surprises.

How Dental Insurance Fee Schedules Work

Every dental insurance company maintains its own internal fee guide — a list of maximum amounts it will pay for each dental procedure. This is entirely separate from the fee guide used by dental clinics in Alberta.

In Alberta, dental clinics typically base their fees on the Alberta Dental Association (ADA) fee guide, which is updated annually to reflect the true cost of delivering care — including staff wages, materials, sterilisation equipment, and clinic overhead. Insurance companies, however, set their own schedules independently, and many have not kept pace with ADA fee guide increases.

A Simple Example of How the Gap Appears

• Your dentist charges $200 for a procedure, based on the current ADA fee guide.
• Your insurance company’s internal fee schedule lists the same procedure at $160.
• Your plan covers 100% — of the $160 your insurer has approved.
• You are billed the remaining $40 difference by your dental clinic.

This $40 difference is called the co-insurance gap or fee schedule shortfall, and it has nothing to do with how your dentist prices their services. It reflects the fact that your insurer’s approved amount has not kept up with the actual cost of care.

Why Insurance Companies Use Outdated Fee Schedules

Insurance companies are not required by law to align their fee schedules with the ADA fee guide. Many insurers update their internal schedules infrequently — sometimes only every few years — while dental clinic fees are adjusted annually. Over time, this creates an increasingly large gap between what your plan covers and what your care actually costs.

This is not unique to any one insurer. It is an industry-wide practice across Canada, and it affects patients in Calgary NW and across Alberta equally, regardless of which insurance company they are with.

Other Reasons You May Still Have a Balance Owing

Beyond fee schedule differences, there are several other common reasons why your out-of-pocket cost may be higher than expected, even with strong coverage:

• Annual maximums: Most dental plans have a yearly cap on benefits — often between $1,000 and $2,000. Once that limit is reached, all remaining costs are your responsibility until the next benefit year.
• Waiting periods: Some plans require you to be enrolled for a set period before certain treatments are covered. Procedures carried out during a waiting period may not be reimbursed.
• Missing tooth clauses: If a tooth was missing before your coverage began, some insurers will not cover replacement treatments such as dental implants or dental bridges.
• Frequency limitations: Your plan may only cover certain procedures — such as teeth cleaning — once or twice per year. Additional visits within that period will not be covered.
• Treatment not considered “medically necessary”: Insurers may classify some procedures as cosmetic rather than essential, and decline to cover them entirely.
• Deductibles: Many plans require you to pay a deductible (an annual out-of-pocket amount) before your coverage begins to apply.

What “Direct Billing” Means — and What It Doesn’t

Many Calgary dental clinics, including Expressions Dental, offer direct billing to your insurance provider. This means your clinic submits your claim on your behalf, and your insurer pays their portion directly to the clinic. It is a convenience — it removes the step of you paying upfront and waiting for reimbursement.

However, direct billing does not mean your insurance covers the full cost of treatment. You are still responsible for any amount your insurer does not cover, including the fee schedule gap described above.

How to Avoid Unexpected Dental Bills

There are practical steps you can take to reduce the chance of an unexpected balance after your appointment:

• Request a predetermination: Before any major procedure, ask your dental clinic to submit a predetermination (also called a pre-authorisation) to your insurer. This gives you a written estimate of exactly what your plan will cover before treatment begins.
• Read your benefit booklet: Your insurance provider should supply a summary of your benefits. Reviewing it — particularly the fee schedules, annual maximums, and exclusions — will help you understand your real coverage level.
• Ask your dental clinic about fees upfront: A reputable dental clinic will always be willing to discuss fees and estimated out-of-pocket costs before you proceed with treatment. Visit our dental fees page to understand how Expressions Dental structures its pricing.
• Explore dental financing: If cost is a concern, dental financing options may help you manage treatment costs over time.
• Check your eligibility for the CDCP: If you do not have private insurance, you may qualify for the Canadian Dental Care Plan (CDCP), a federal programme providing dental coverage to eligible Canadians.

Why Dental Fees in Alberta Are Set the Way They Are

The Alberta Dental Association publishes its fee guide annually based on a thorough analysis of what it costs to operate a dental clinic responsibly and safely. These costs include:

• Wages for licensed dental professionals, including hygienists, assistants, and administrative staff
• Sterilisation and infection control materials and equipment
• Dental supplies, including materials used in fillings, crowns, and other restorations
• Clinic rent, utilities, and technology infrastructure such as digital X-ray equipment
• Continuing education required to maintain licensure

When insurance fee schedules fail to reflect these costs, the difference does not disappear — it is passed on to patients as an out-of-pocket balance.

What to Do If You Have Questions About Your Bill

If you receive a bill from your dental clinic that you did not expect, the most important thing to do is ask. Contact your dental clinic first — they can walk you through exactly what was billed, what your insurer paid, and why a balance remains. You can also contact your insurance provider directly to request a full explanation of benefits (EOB) statement, which outlines precisely how your claim was processed.
