Let's break down what "full coverage" actually means, look at some of the top dental insurance providers in the game right now, and find out how you can maximise your benefits. If you're searching for a plan that won't leave you hanging at your next dentist visit, you'll want to keep reading.

What Does "Full Coverage" Dental Insurance Mean?

Here's a question most people don't ask until they're already sitting in the dental chair: What does my plan cover? Spoiler alert: not all "full coverage" dental plans are created equal.

When insurance providers say “full coverage,” it usually means three things:

Preventive Care

Think cleanings, exams, and routine X-rays—usually covered at 100%.

Basic Procedures

These include fillings, simple extractions, and repairs.

Major Services

Crowns, bridges, root canals, dentures, and sometimes even orthodontics.

But the devil’s in the details. Every plan is different when it comes to waiting periods, annual maximums, and whether or not orthodontics or implants are covered.

Let's meet the six companies making headlines—and smiles—thanks to their comprehensive dental insurance options.

1. Delta Dental: The Old Reliable

Delta Dental is often the first name that comes to mind when discussing dental insurance. Why? For starters, it's the largest dental insurance provider in the U.S., with a massive network of dentists (over 150,000!). That means you're likely to find a provider nearby, wherever you are.

Why people love Delta Dental:

•                  Many plans cover 100% of routine exams, cleanings, and X-rays.
•                  Basic procedures, such as fillings and extractions, are usually covered at 80%, and primary services are covered at 50%.
•                  Some plans even cover orthodontics for both children and adults.

What to watch out for: Annual maximums can vary, and some plans have waiting periods for primary services. Not every employer-sponsored plan includes coverage for orthodontics or dental implants, so be sure to review the fine print carefully.

Good to know: Delta Dental offers several plan types—PPO, HMO, and fee-for-service—so you can choose the one that best suits your needs and style.

2. Cigna: Best For Flexible Plans

Do you travel a lot? Or would you prefer the freedom to see any dentist you choose? Cigna is known for its flexible plans, which offer extensive networks and require no referrals for specialists.

Why people like Cigna:

•                  Most plans have zero deductibles or waiting periods for preventive care.
•                  Up to 100% coverage for preventive services, and good coverage on fillings and root canals.
•                  Cigna's "Dental 1500" plan stands out for its comprehensive coverage, which includes major dental work and certain orthodontic services.
•                  Online tools and customer support are highly rated.

Keep in mind: Like most plans, Cigna has annual maximums, typically ranging from $1,000 to $1,500 per year. Watch for waiting periods on primary services if you're buying an individual plan.

Handy tip: Cigna often includes discounts on vision and hearing services as a bonus.

3. Guardian: Great For Families

Guardian might fly under the radar, but it's a favourite for families. Their plans are popular with employers, but individual plans also have their appeal.

Why families pick Guardian:

•                  Coverage for all three tiers: preventive, basic, and primary dental care.
•                  Some plans offer orthodontic coverage for both children and adults, in some instances.
•                  No waiting periods on preventive care, and some plans waive waiting periods for basic care if you’ve had prior coverage.
•                  Generous annual maximums compared to many competitors.

What to consider: Availability varies by state, and not all plans cover orthodontics for adults. Double-check the details before you sign up.

4. Humana: Good For Seniors

Thinking about dental care in retirement? Humana has tailored options, especially for those on Medicare Advantage plans.

Why Humana stands out:

•                  Extensive network and strong preventive coverage.
•                  Great for primary services—like crowns and dentures—that older adults are more likely to need.
•                  Some plans include “no waiting period” for preventive and basic services.
•                  Plans with high annual maximums are available.

Heads up: Premiums and out-of-pocket costs can be a little higher for primary coverage, but the extra peace of mind may be worth it.

5. UnitedHealthcare: Solid Nationwide Coverage

UnitedHealthcare is everywhere, and its dental insurance is just as broad. They offer a range of plans for all budgets, along with easy bundling options for other types of insurance.

Why UnitedHealthcare gets clicks:

•                  Covers 100% of routine care, like exams and cleanings.
•                  Good coverage for basic and significant work—think crowns, bridges, and even some plans with orthodontic options.
•                  Impressive online resources for finding in-network dentists or tracking claims.
•                  Available in most states.

Note that some plans have waiting periods for primary services. Additionally, not all options are available in every location, so your choices may vary depending on your zip code.

6. MetLife: A Favourite For Group Plans

MetLife is a well-known name in employer-sponsored dental coverage, but its individual and family plans are also worth considering.

Why people sign up for MetLife:

•                  Big national network and straightforward plan designs.
•                  Preventive care is covered at 100%, and strong coverage for fillings and extractions.
•                  Coverage for implants in some plans—a rarity!
•                  Some options include orthodontics for kids.

Look out for: Higher-tier plans cost more, and not every state has the same options.
