Most people sign up for dental coverage during open enrollment, pick a plan that seems reasonable, and then don't think too much about it — until they actually need to use it. That's when the surprises tend to show up.
Unexpected out-of-pocket costs, services that aren't covered, or annual limits that run out faster than expected are all common frustrations. The good news is that understanding your coverage before you need it can prevent most of these issues. Here's what to look for — and what often gets missed.

1. Understand the Three-Tier Coverage Structure
Most dental insurance plans organize coverage into three categories, each with different reimbursement levels:
● Preventive care (cleanings, X-rays, exams) — typically covered at 100%
● Basic restorative care (fillings, simple extractions) — usually covered at 70–80%
● Major restorative care (crowns, bridges, root canals) — often covered at just 50%
This structure sounds clear enough on paper, but the definitions of what falls into each tier vary between insurers. A procedure your previous plan covered as "basic" might be classed as "major" by your current one. Always read the fine print carefully.
