What Does Dental Insurance Actually Cover?

Opening your dental insurance plan documents and trying to understand what’s covered feels like deciphering a technical manual. Coverage varies between plans, but most dental insurance follows a predictable pattern dividing services into three categories: preventive, basic, and major. Each category has different coverage percentages, waiting periods, and limitations. Understanding what your plan covers and what it doesn’t helps you plan treatment and budget for out-of-pocket costs.

Preventive Care: 100 Percent Coverage

Preventive services are where dental insurance shines. Nearly all plans cover preventive care at 100 percent, meaning your insurer pays the full cost with no deductible or waiting period. Preventive services include routine exams, professional cleanings, X-rays, and fluoride treatments. Most plans cover two cleanings and exams per year, which aligns with Bonin Dental Care’s recommendation for twice-yearly dental cleanings and checkups.

Some plans also cover sealants (protective coatings applied to molar chewing surfaces) at 100 percent, though typically only for children. Periodontal evaluations and basic gum assessments fall under preventive care. Periodontal scaling and root planing, which treats early gum disease, sometimes is covered under preventive benefits, though some plans classify it as basic restorative.

The 100 percent coverage for preventive care is the strongest part of dental insurance. Your insurer wants you to maintain oral health because prevention is far less expensive than treating advanced disease. If you only use one benefit from your dental insurance, make it preventive care. Regular checkups catch problems early before they become expensive.

Basic Restorative Care: 70-80 Percent Coverage

Once you move beyond prevention, coverage percentages drop. Basic restorative care typically includes fillings, simple extractions, and minor endodontic (root canal) therapy. Most plans cover these services at 80 percent after your deductible is met. Your responsibility is the remaining 20 percent of the allowed amount.

Important detail: your insurer sets an “allowed amount” for each procedure. If your dentist charges more than the allowed amount, the difference is your responsibility even if your insurance covers 80 percent of the allowed amount. At Bonin Dental Care, we discuss both the insurance allowed amount and our actual fee so you understand your full financial obligation. In some cases, we can provide treatment using alternate materials covered more generously by your plan, such as amalgam fillings instead of tooth-colored composite fillings.

Basic care waiting periods vary. Many plans cover basic services immediately for new members, though some have 6-12 month waiting periods. Check your specific plan documents to understand when basic coverage begins. If you’re switching plans, this timing might affect treatment scheduling. Dr. Bonin can help discuss whether treatment should proceed now or wait until coverage activates.

Major Restorative Care: 50 Percent Coverage

Major restorative services include crowns, bridges, complex root canals, dentures, and dental implants. These are covered at only 50 percent by most plans, meaning you pay half the allowed amount out of pocket. Given that major restorative work is often the most expensive dental treatment, this 50 percent coverage leaves significant costs to patients.

For example, a crown might have an allowed amount set by the insurance company. Your insurance pays its share, and you pay the remainder. If your dentist’s actual fee exceeds the allowed amount, you pay the difference as well. This is where treatment costs can become substantial and why major work often triggers conversations about financing, phasing treatment, or exploring alternate treatment approaches.

Major service waiting periods are typically 12 months for new plan members. If you recently changed insurance, confirm that major coverage has begun before committing to expensive treatment. Some employers’ plans have longer waiting periods, so always verify.

What’s Typically Not Covered

Cosmetic treatments are not covered by any dental insurance. Teeth whitening for esthetic reasons, veneers placed purely for appearance, and other cosmetic procedures fall entirely to the patient. If you’re interested in teeth whitening or cosmetic smile improvements, understand that insurance won’t help with costs.

Orthodontic treatment (braces and clear aligners) is sometimes covered, but usually only for children, and coverage is often limited to a percentage of treatment cost. Adult orthodontics are rarely covered. Check your specific plan documents.

Dental implants are sometimes covered, but often with restrictions or at a lower percentage than traditional crowns. Some plans don’t cover implants at all, covering only bridge or denture replacements instead. This is worth confirming before committing to implant treatment, as it affects your overall cost and treatment planning.

Periodontal disease treatment can be complicated. Preventive periodontal evaluations are usually covered, but treatment for periodontal disease is sometimes classified as basic care (80 percent coverage) and sometimes as major care (50 percent). Some plans have annual visit limits for periodontal services. If you have or are at risk for gum disease, understand how your plan covers treatment and maintenance.

The Role of Your Annual Maximum

Even within these coverage categories, your annual maximum limits total insurance payout. If you hit your annual maximum, you pay 100 percent of remaining costs regardless of their category. This is where carefully sequencing treatment across calendar years can help. If you need significant work totaling more than your annual maximum, discuss with Dr. Bonin whether phasing work across two years maximizes your insurance benefits.

Alternate Benefit Clauses

Some insurance plans include “alternate benefit” clauses that restrict coverage to the most basic version of a procedure. A plan might cover amalgam fillings but only pay for amalgam even if you prefer tooth-colored composite. Or they might cover traditional crowns but cover only a percentage of full porcelain if you choose that material over less expensive alternatives.

When a plan includes an alternate benefit clause, your insurance pays based on the basic option, and you pay the difference if you choose an upgraded material. Understanding this before treatment helps you make informed decisions. Ask us about coverage before choosing materials so there are no surprises.

Specific Questions to Ask Your Plan

Don’t hesitate to contact your insurance company directly with specific questions about your coverage. Ask about the allowed amount for a specific procedure you’re considering, what waiting periods apply, whether you’ve used any of your annual maximum, and what your out-of-pocket responsibility will be. Getting answers in writing from your insurer prevents misunderstandings.

This is exactly why predetermination requests exist. We submit a treatment plan to your insurer and ask them to confirm in writing what they’ll cover and what you’ll owe. You get certainty, we avoid billing disputes, and everyone proceeds confidently.

Making Insurance Work for You

Your dental insurance is most valuable for preventive care, which is fully covered. Maximize those benefits by visiting twice yearly for checkups and cleanings. When you need restorative treatment, understand your coverage percentage and annual maximum so you can plan accordingly. Work with Dr. Bonin to understand the full cost of treatment and your financial responsibility before proceeding.

If significant treatment needs exceed your annual maximum or comfort level, discuss alternative approaches, including phased treatment or lower-cost options that your plan might cover more generously. The goal is getting you healthy while respecting your financial situation.
