Imagine trying to solve a puzzle with two different sets of instructions. That’s often how families in Brampton feel when they have more than one dental insurance plan. Whether it’s a spouse’s plan and your own, or coverage through both parents for a child, managing dual dental benefits can feel like a maze. But what if there was a way to make those two plans work together harmoniously, maximizing your coverage and significantly lowering your out-of-pocket costs? That’s where the magic of “Coordination of Benefits” (COB) comes in. It’s not about getting “double benefits” (a common myth!), but about ensuring your family gets the most out of every dollar you and your employer invest in dental care.
For Brampton families, understanding COB is key to unlocking greater financial peace of mind and access to essential dental services.
Unraveling the Mystery: What is Coordination of Benefits (COB)?
At its heart, Coordination of Benefits (COB) is a set of rules used by insurance companies to determine how two or more dental plans will pay benefits when you have coverage under more than one plan.
Its primary goal is to prevent you from being reimbursed for more than 100% of the actual cost of a dental procedure. Think of it as a carefully orchestrated dance between your insurance providers to ensure fair and accurate payment.
The core concept revolves around distinguishing between your primary and secondary dental plans:
- Primary Plan: This is the plan that pays its benefits first.
- Secondary Plan: This plan then considers the remaining balance after the primary plan has paid, and may cover some or all of what’s left, up to its own benefit limits.
The Golden Rule of COB: You won’t get more than 100% of the total treatment cost back.
Instead, COB helps fill the gap between what your primary plan covers and the actual expense, reducing your personal share of the bill. It’s about optimizing benefits, not duplicating them.
The Family Playbook: Navigating Dual Coverage Scenarios
The rules for determining primary and secondary plans become particularly important for families, as different relationships come with different guidelines.
When Spouses Both Have Dental Plans
This is one of the most common dual coverage scenarios. If you and your spouse each have your own dental plan through your respective employers, you generally designate your own plan as primary for yourself.

For your spouse, their plan is primary, and your plan would be secondary for them (and vice-versa).
Let’s say you need a filling that costs $200.
- Your primary plan might cover 80% ($160).
- Your secondary plan would then look at the remaining $40. If it also covers 80% of fillings, it might pay an additional portion of that $40, bringing your out-of-pocket closer to zero.
Expert Insight from Dr. Seema Shetty:
“Many families in Brampton are surprised to learn how much they can save by properly coordinating their benefits. It’s a fantastic way to make comprehensive dental care more affordable. We regularly help our patients navigate these details, providing pre-authorizations and submitting claims to ensure they maximize their coverage.”
Children with Dual Parent Plans: The “Birthday Rule” and Beyond
Determining primary and secondary coverage for children when both parents have dental plans can be a bit more nuanced. The most common guideline here is the “Birthday Rule.”
The Birthday Rule dictates that the parent whose birthday falls earlier in the calendar year (month and day, not year) will have their plan designated as the child’s primary coverage.
- Example: If Mom’s birthday is May 15th and Dad’s is August 20th, Mom’s plan would be the primary for their children. It has nothing to do with who is older or whose plan is “better.”
What if birthdays are the same? In rare cases where both parents share the same birthday, the plan that has been in effect longer (i.e., the older policy) is usually considered primary.
Court Orders for Divorced Parents: In situations of divorce or legal separation, a court order may specify which parent is responsible for the child’s dental expenses. If such an order exists, it generally overrides the Birthday Rule.
Always provide a copy of the court order to both your dental office and insurance companies.
Scenario Example: The Sharma Family in Brampton
The Sharma family lives in Brampton. Mrs. Sharma’s birthday is April 10th, and Mr. Sharma’s is September 5th. Their son, Rohan, needs a dental crown, which costs $800.
According to the Birthday Rule, Mrs. Sharma’s plan is Rohan’s primary. Her plan covers 50% of major procedures. It pays $400.
The remaining $400 is submitted to Mr. Sharma’s plan (secondary). His plan also covers 50% of major procedures, but due to COB, it might cover an additional portion of the remaining* amount. If the plans allow, Rohan’s total reimbursement could come closer to 80-90% of the cost, significantly reducing the family’s out-of-pocket expense compared to using just one plan.
Canadian Specifics: CDCP, Provincial Plans, and Your Private Coverage
Navigating dental plans in Canada, especially with the introduction of the new Canadian Dental Care Plan (CDCP), adds another layer of consideration for families.
The Canadian Dental Care Plan (CDCP) is designed to provide dental coverage for eligible Canadian residents who do not have access to private dental insurance. It is generally considered a “payer of last resort.”
This means that if you or your family members already have a private dental plan (like through an employer), the CDCP is typically not intended to coordinate with it. For those who qualify for CDCP, it would act as their primary plan, but it generally does not “top up” existing private insurance.
For families with existing private dual coverage, the CDCP usually won’t change how your private plans coordinate. However, it’s crucial to understand who is eligible for the CDCP and how it interacts with any existing coverage you might have, as rules and guidelines can evolve.
Provincial Programs: Beyond the federal CDCP, Ontario also has programs like Healthy Smiles Ontario (for children and youth from low-income families) and the Ontario Seniors Dental Care Program (OSDCP).
If a family member is eligible for and enrolled in one of these provincial programs, it would typically be considered the primary plan, with any private plans acting as secondary. Always consult your specific provincial program details and private insurer for precise coordination rules.
Decoding Your Policy: Key Terms and Considerations
Understanding a few key terms in your insurance policies can make a huge difference in maximizing your COB.
Deductibles, Annual Maximums, and Waiting Periods
- Deductibles: This is the amount you must pay out-of-pocket before your insurance plan starts paying benefits. With dual plans, you might need to meet a deductible for each plan, or sometimes the secondary plan will waive its deductible if the primary plan has already satisfied it.
- Annual Maximums: This is the total amount your insurance plan will pay for your dental care within a benefit year. When you have dual coverage, these maximums typically do not combine. Instead, the primary plan pays up to its maximum, and then the secondary plan may cover additional costs up to its own maximum, effectively allowing you to access higher total benefits across both plans.
- Waiting Periods: Some plans have a waiting period before certain procedures (especially major ones) are covered. If you have dual plans, one plan might cover a procedure immediately while the other has a waiting period, allowing you to get care sooner using the more immediate coverage.
Understanding Different COB Methods (No Jargon, We Promise!)
While the specifics can be complex, understanding the basic types of COB can shed light on how your reimbursement works:
- Traditional COB (or Non-Duplication): This is the most common. The primary plan pays its benefit, and the secondary plan then pays the remaining balance up to its own allowed percentage, but not exceeding 100% of the total cost. It ensures you don’t over-collect.
- Maintenance of Benefits (MOB): Less common now, this method allows the secondary plan to pay benefits as if it were primary, but the total paid by both plans won’t exceed what the primary plan would have paid had it been the only coverage. This can sometimes result in a lower total reimbursement compared to traditional COB.
- Carve Out: With this method, the secondary plan “carves out” or subtracts the amount the primary plan paid from its own calculated benefit amount. The secondary plan then pays the difference. This usually means the combined benefits still don’t exceed 100% of the allowed charge.
The key takeaway? Your specific plans dictate which method is used. Don’t hesitate to ask your plan administrator or dental office for clarity.
Maximizing Your Benefits: Practical Strategies for Brampton Families
Now that you understand the mechanics, let’s talk about how to proactively make the most of your dual dental coverage in Brampton.
Proactive Steps for Smart Coverage
- Know Your Plans Inside Out: Get a copy of both benefit booklets (or access online portals) for your primary and secondary plans. Understand the percentages for different procedures (preventive, basic, major), annual maximums, and any exclusions.
- Regular Check-ups are Key: Don’t wait for a problem! Preventive care is almost always covered at 100% by most plans. Regular cleanings and exams help catch issues early, before they become expensive major procedures. This also prevents potential issues that could fall under waiting periods for secondary plans.
The Claims Process with Two Plans
Submitting claims with dual plans might seem intimidating, but your dental office is usually well-versed in handling this.
- Inform Your Dental Office: Crucially, let your dental care team know you have two active dental plans. Provide them with all the necessary policy numbers and details for both.
- Primary Claim First: Your dental office will typically submit the claim to your primary insurance plan first.
- Explanation of Benefits (EOB): Once the primary plan processes the claim, they will send an Explanation of Benefits (EOB) detailing what they paid and what’s remaining.
- Secondary Claim: Your dental office will then submit the claim, along with the EOB from your primary plan, to your secondary insurance provider. This allows the secondary plan to assess the remaining balance and pay according to their COB rules.
- Your Responsibility: After both plans have processed, you will be responsible for any remaining balance.
Some dental offices, like Smile Makers Dental Care, can electronically submit claims to both your primary and secondary plans, simplifying the process for you. Be sure to ask about their direct billing capabilities.
Common Misconceptions & Troubleshooting
Even with a good understanding, questions and minor hurdles can arise.
Myth vs. Fact: Does Dual Coverage Mean 100% Reimbursement?
Myth: “If I have two dental plans, I’ll get 100% of my dental costs covered.”
Fact: While dual coverage significantly reduces your out-of-pocket expenses, it rarely results in 100% reimbursement for every procedure. Insurance plans often have “usual and customary” limits, deductibles, co-pays, and non-covered services. COB helps maximize what you get, but it’s not a magic bullet for free dental care.
What to Do When a Claim is Denied
A denied claim can be frustrating, but it’s not always the final answer.
- Review the EOB: Carefully read the Explanation of Benefits from both insurers. It will state why a claim was denied (e.g., waiting period, non-covered service, coordination issue).
- Contact Your Dental Office: Your dental team often has experience with these issues and can help clarify the situation or resubmit information.
- Contact Your Insurance Provider(s): If you still have questions, call the customer service number on your insurance card. Be prepared with your policy numbers, the date of service, and the claim number.
- Appeal: If you believe the denial is an error, you have the right to appeal the decision. Your insurance company will have a formal appeals process.
Are There Situations Where Dual Coverage Isn’t Worth It?
For most families, especially those with children, the benefits of dual coverage (reduced out-of-pocket costs, access to a wider range of services) often outweigh the complexities.

However, if the premiums for a secondary plan are exceptionally high, and your primary plan offers generous coverage with minimal out-of-pocket expenses, it might be worth evaluating if the cost of the second plan truly provides significant additional value.
This is a personal financial decision that should be weighed carefully.
Your Questions Answered: Family COB FAQ
What is Coordination of Benefits (COB)?
COB is a set of rules used by insurance companies to determine how two or more plans will pay benefits when you have multiple coverages, preventing you from receiving more than 100% of the cost.
How do I know which plan is primary for my child?
Generally, the “Birthday Rule” applies: the parent whose birthday falls earlier in the calendar year (month and day) provides the primary coverage for the child. Court orders for divorced parents can override this.
Can I use both plans for the same procedure?
Yes, that’s precisely the purpose of COB! Your primary plan pays first, and then your secondary plan considers the remaining balance, often reducing your out-of-pocket costs.
What if one plan covers something the other doesn’t?
If your primary plan doesn’t cover a specific procedure, but your secondary plan does, the secondary plan may pay its benefit as if it were the primary, subject to its own rules and limitations. This can be a huge advantage for accessing more comprehensive care.
How does the new CDCP affect my existing dual private plans?
The Canadian Dental Care Plan (CDCP) is primarily for eligible Canadians who do not have access to private dental insurance. If you have existing private dual plans, the CDCP is generally not intended to coordinate or “top up” those plans. Your private plans will continue to coordinate as usual.
Do I need to inform my dentist about both plans?
Absolutely! Providing your dental office with details for all your active dental plans is crucial. They can help you navigate the claims process, submit pre-determinations, and ensure you maximize your benefits.
