What Are Dental Codes?
Dental codes are standardized numbers and letters used to describe dental procedures. They were created by the American Dental Association (ADA) to ensure consistency across dental practices and insurance claims. Each code corresponds to a specific treatment, such as a filling, extraction, or cleaning.
For example:
- D0120: Periodic oral evaluation
- D1110: Adult prophylaxis (cleaning)
- D2140: Amalgam filling (one surface)
These codes help dentists communicate with insurance companies and ensure that patients receive the correct coverage for their treatments.
Why Should You Care?
Understanding dental codes can save you money and prevent surprises on your bill. If you know what each code means, you can verify that you’re being charged for the correct procedures. It also helps you understand your insurance coverage and avoid unnecessary expenses.

For example:
- D1208: Topical fluoride treatment (like a superhero shield for your teeth!)

By turning dental codes into a game, kids can learn about their dental health while having fun.
