Does Dental Insurance Cover Fillings? Your Guide to Coverage
A dental filling is one of the most common procedures performed by dentists to treat a cavity. If you have a dental insurance plan, you're likely wondering if this essential treatment is covered. The good news is, yes, dental insurance almost always covers fillings. However, the extent of the coverage—and your out-of-pocket cost—depends on a few key factors.
To understand your benefits, you need to know about the different types of fillings and how your insurance plan categorizes them.

The 100-80-50 Rule: Fillings as a "Basic Procedure"
Dental insurance plans often follow a common coverage model, sometimes called the 100-80-50 rule. This framework is a good way to predict your coverage for different types of dental work.
100% Coverage: Preventive care (e.g., cleanings, exams).
80% Coverage: Basic procedures (e.g., fillings, simple extractions, root canals).
50% Coverage: Major procedures (e.g., crowns, bridges, dentures).
Since fillings are a necessary treatment to restore a tooth's function and prevent further decay, they are typically classified as a basic procedure. This means your insurance plan will usually cover a significant portion of the cost, often around 80%.
Your Out-of-Pocket Cost: After your deductible is met, you will be responsible for the remaining percentage, which is often a 20% co-pay. For example, if a filling costs $150 and your plan covers 80%, you would pay $30.
Understanding the Different Types of Fillings
The type of filling material used can also affect your coverage. Most insurance plans have a preferred type of material they cover more generously.
1. Amalgam Fillings (Silver Fillings)
What they are: Amalgam fillings are a mixture of metals, including silver, copper, and mercury. They are durable and have been used for over 150 years.
Insurance Coverage: Amalgam fillings are considered the "standard of care" by many insurance providers. Because they are the least expensive option, most plans cover them at a full 80% (or whatever percentage they allocate for basic procedures).
2. Composite Fillings (Tooth-Colored Fillings)
What they are: Composite fillings are made from a resin material that can be color-matched to your natural teeth. They are more aesthetically pleasing and are often used for teeth that are visible when you smile.
Insurance Coverage: This is where it gets a little more complex. Some insurance plans treat composite fillings just like amalgam and cover them at 80%. However, many plans will only cover composite fillings on the front teeth (incisors and canines), which are considered "visible." For back teeth (premolars and molars), the plan may have a "downgrade clause."
What is a "Downgrade Clause"?
A downgrade clause means that your insurance company will only pay the amount they would have paid for a less expensive amalgam filling, even if you choose to get a more expensive composite one.
How it works: Let's say a composite filling costs $200, but an amalgam filling would have cost $150. Your insurance plan will calculate their 80% coverage based on the $150 amalgam cost, not the $200 composite cost. This means they will pay $120 (80% of $150), and you will be responsible for the remaining $80 ($200 - $120).
This can result in a higher out-of-pocket cost for you, even though the procedure is technically covered.
Important Factors That Affect Your Coverage
Beyond the type of filling, a few other things can influence how much you pay.
Your Deductible: This is the amount you must pay out-of-pocket before your insurance begins to cover a percentage of your costs. If you haven't met your annual deductible, you will pay the full cost of the filling until you do.
Annual Maximum: Most dental insurance plans have an annual maximum benefit, which is the total amount the insurance company will pay in one calendar year. If you've already reached your annual maximum, you will be responsible for the full cost of the filling.
Waiting Periods: Some plans have a waiting period for basic procedures like fillings, meaning you must be enrolled in the plan for a certain amount of time (e.g., 3-6 months) before you can get coverage for a filling.
In-Network vs. Out-of-Network: Your cost will almost always be lower if you see an in-network dentist, as they have a pre-negotiated fee schedule with your insurance company.
Summary: Your Best Practices
In conclusion, dental fillings are a standard, covered benefit in virtually all dental insurance plans. To ensure you're getting the most from your coverage and to avoid unexpected costs, it's always a good idea to:
Ask your dentist's office staff for a pre-treatment estimate: They can submit a request to your insurance company to get an exact breakdown of what will be covered and what your out-of-pocket cost will be.
Understand your plan's policy on composite fillings: Ask if your plan has a downgrade clause for back teeth.
Know your deductible and annual maximum: Keep track of your benefits to avoid surprises.
By taking these steps, you can confidently proceed with the necessary treatment knowing exactly what your insurance will and will not cover.
