Delta Dental of Minnesota makes it easy to decode some of the confusion around dental insurance. There are many terms that dentists and insurance providers uses to describe procedures and it can be difficult to understand what all of these terms mean.
Use this resources to understand the jargon with clear explanations of common dental terms. For many of the more complicated terms, we have provided examples which may make it easier to understand in context.
Abrasion The abnormal wearing away of tooth substance by a mechanical process.
Abscess Acute or chronic, localized inflammation, with a collection of pus, associated with tissue destruction and, frequently, swelling, usually secondary to infection.
Abutment A tooth or teeth used to support and anchor a fixed or removable prosthesis.

Deductible Most dental plans have a specific dollar deductible. It works like your car insurance deductible. During a benefit period, you will have to personally pay a portion of your dental bill before your insurance carrier will contribute to your bill. Your plan booklet will describe how your deductible works. Plans do vary on this point. For instance, some dental plans will apply the deductible to preventive treatments, and others will not.
