A

Annual Maximum

The annual maximum is the maximum amount a dental insurance plan will pay for covered services within a single year.

For example, if your plan has a $1,500 annual maximum, the insurance provider will not pay more than that amount for dental treatments during the year.

To understand how these limits affect coverage, you can explore our guide to dental insurance costs and coverage limits.

C

Coinsurance

Coinsurance is the percentage of a dental treatment cost that you pay after meeting your deductible.

For example, if a dental procedure costs $200 and your plan covers 80%, you would pay the remaining 20% as coinsurance.

Understanding coinsurance is important when comparing plans in our guide to compare dental insurance plans.

D

Deductible

A deductible is the amount you must pay out of pocket before your dental insurance plan begins covering certain procedures.

Many dental insurance plans require a deductible for basic or major procedures, while preventive services may be covered without one.

To better understand how deductibles affect pricing, see our dental insurance cost guides.

H

HMO Dental Plan

An HMO dental plan (Health Maintenance Organization) requires you to choose a primary dentist within a specific network of providers.

These plans often have lower monthly premiums but may limit your ability to visit dentists outside the network.

You can learn more about how these plans work in our guide to types of dental insurance plans.

P

PPO Dental Plan

A PPO dental plan (Preferred Provider Organization) allows you to visit both in-network and out-of-network dentists.

However, visiting dentists within the provider network typically results in lower costs and better coverage.

Our guide to types of dental insurance plans explains how PPO plans compare with other options.

N

Network Dentist

A network dentist is a dental provider who has agreed to provide services at negotiated rates with a dental insurance company.

Visiting an in-network dentist usually reduces your out-of-pocket costs compared to seeing an out-of-network provider.

Understanding provider networks can help when you compare dental insurance plans.

W

Waiting Period

A waiting period is the amount of time you must wait after purchasing a dental insurance plan before certain procedures become eligible for coverage.

Many plans cover preventive services immediately but require waiting periods for major treatments such as crowns or implants.

Our article on dental insurance waiting periods explains how these restrictions work.
