Check My Dental Bill — FreeWhat this procedure is
D3330 is commonly used for root canal treatment on a molar. Different tooth types use different CDT codes, so confirm the code matches the tooth treated.
There is no single universal price. Your EOB can show the provider charge, the plan's allowed amount, the amount insurance paid, and the portion assigned to you.
What to check on your EOB
- • Confirm the tooth number and root canal code match.
- • Check whether X-rays or narratives were required.
- • Review related buildup and crown charges separately.
- • If denied, read the denial reason before paying the full office fee.
Questions to ask the dental office
- • Which tooth was treated and which CDT code was submitted?
- • Were all required X-rays or notes sent?
- • Are the buildup and crown separate charges?

FAQs
What dental code is commonly associated with root canal?
A commonly associated code is D3330, though the exact CDT code depends on the service performed.
Should I compare the dental office charge or the insurance allowed amount?
For an in-network claim, the allowed or negotiated amount on the EOB is usually the more useful starting point for understanding what the plan recognized before deductible, coinsurance, copay, and other benefit rules.
What if the EOB and dental bill do not match?
Ask the dental office to reconcile the statement to the EOB before paying a disputed balance. Confirm that contractual adjustments, plan payment, deductible, coinsurance, and any denial reason were applied correctly.
