Dental insurance is structured very differently from medical insurance. This guide explains the terminology, the typical coverage tiers, and how to make every dollar count.
PPO, HMO, indemnity, and discount plans - a quick decoder
PPO (Preferred Provider Organization) plans offer the most flexibility - you can see any dentist, but in-network providers offer reduced fees. Most California patients have PPO plans through Delta Dental, Cigna, Aetna, MetLife, Guardian, or Blue Shield. HMO (DMO) plans require you to pick a primary dentist and stay in-network; they are cheaper but more restrictive. Indemnity plans reimburse a percentage of "usual and customary" fees regardless of provider - rare today. Discount plans are not insurance at all; they offer a flat fee schedule for a yearly membership. Our in-house membership plan is a discount-style alternative for uninsured patients.
The 100/80/50 coverage tiers
Almost every PPO plan groups procedures into three tiers:
- Preventive (typically 100% covered): Cleanings, exams, bitewing X-rays, fluoride for kids.
- Basic restorative (typically 70-80%): Fillings, simple extractions, some non-surgical periodontal therapy.
- Major restorative (typically 50%): Crowns and bridges, root canals (sometimes basic), surgical extractions, dentures, implant restorations.
Not every plan follows this exact structure - read your benefits booklet, or ask our front office to verify your benefits before treatment.
Annual maximums, deductibles, and the calendar reset
Your annual maximum is the most your plan will pay in a benefit year - usually $1,000, $1,500, or $2,000. Once you hit it, you pay 100% out of pocket until the new year. Your deductible ($25-$100 typical) is the amount you pay before insurance kicks in for non-preventive work. Most plans reset on January 1, but some employer plans use a fiscal-year reset. If you have $800 of unused benefits in November, scheduling completion of treatment before December 31 can save you the equivalent dollar amount in the new year.
Missing-tooth clauses, frequency limits, and waiting periods
These are the three most common surprise denials:
- Missing-tooth clause: Excludes replacement of teeth that were extracted before the policy started. If you had a tooth pulled in 2018 and got new insurance in 2024, your bridge for that gap may not be covered.
- Frequency limits: Two cleanings per year, one set of bitewings per year, one panoramic X-ray every 3-5 years, one crown per tooth every 5-7 years.
- Waiting periods: New plans often impose a 6-12 month wait before major work is covered.
We verify all three at the benefits check before any major treatment.
Pre-treatment estimates and how to use them
A pre-treatment estimate (sometimes called a predetermination) is a written commitment from your insurer estimating what they will pay for a planned procedure. For any treatment over about $500, we recommend submitting a pre-estimate. It typically takes 7-14 days, but the answer protects you from billing surprises and helps you plan financing. Speaking of financing - if your benefits don't cover the full cost, our financing page outlines third-party payment options.
Frequently asked questions
- Are you in-network with my insurance?
- We are in-network with most major California PPO plans, including Delta Dental Premier, Cigna, Aetna, MetLife, Guardian, and Blue Shield. Call our front office or visit our insurance page to verify your specific plan.
- What's the difference between "in-network" and "covered"?
- In-network means we have agreed to a reduced fee schedule with your insurer. Covered means your plan will pay a percentage of that reduced fee. A procedure can be in-network but not covered - for example, cosmetic teeth whitening is rarely a covered benefit.
- Will my plan cover Invisalign or veneers?
- Cosmetic procedures are usually not covered. However, Invisalign is sometimes covered when prescribed for medically necessary bite correction, and veneers are occasionally covered when used to repair structural damage. We always submit for review when there is a medical case.
- Can I use HSA or FSA dollars for dental work?
- Yes, almost all dental procedures - including most cosmetic work like whitening - qualify for HSA and FSA reimbursement, because the IRS treats dental care as medical. Save your itemized receipt and submit it through your HSA/FSA portal.
