A dental filling restores a tooth after a cavity, fracture, or small chip by removing damaged tooth structure and filling the defect with a restorative material. The procedure itself takes 30 to 60 minutes, usually under local anesthesia. Composite (tooth-colored) resin is the modern standard material because it bonds directly to tooth structure, comes in shades matching surrounding teeth, and requires less drilling than classic silver amalgam. Amalgam fillings are cheaper and still used by some offices, particularly for back teeth. Glass ionomer and resin ionomer fillings are sometimes used for primary teeth or areas with low bite force. Fees are billed by the number of tooth surfaces being filled — one-surface (occlusal only) fillings are cheaper than multi-surface (MOD) fillings that wrap around several faces of the tooth. Large or deep fillings that approach the nerve may need a protective liner, which can be a separate charge.
費用に影響する要素
- Material: composite (tooth-colored) fillings cost more than amalgam; ceramic or gold inlays cost substantially more than either.
- Number of surfaces: one-surface fillings are the cheapest; two-, three-, and four-surface fillings (MO, MOD, or complex) increase stepwise.
- Tooth location: posterior (back-tooth) fillings are typically billed higher than anterior (front-tooth) fillings of the same material.
- Adult vs primary tooth: pediatric fillings on primary teeth are a different code set and often priced lower.
- Provider type: general-dentist office fees vary; specialist or cosmetic-focused practices charge more.
- Insurance annual maximum: fillings count against the dental plan's annual benefit cap.
節約方法
- Use your insurance's basic-services coverage; PPO plans typically pay 70-80% for fillings after deductible.
- Ask whether amalgam is appropriate for a back tooth where aesthetics don't matter — it's cheaper and durable.
- Consider a dental school clinic for low-cost fillings performed by supervised students.
- Request a pre-treatment estimate from your insurer so you know the patient portion before the appointment.
- Dental savings plans discount fillings 15-30% for uninsured patients.
- Use your HSA or FSA to pay the patient portion with pre-tax dollars.
保険とカバレッジに関する注意事項
Dental PPO plans typically cover composite and amalgam fillings as a basic service at roughly 70-80% after deductible, subject to an annual maximum benefit (commonly $1,000-$2,000). Some plans reimburse composite fillings on back teeth only at the amalgam rate, requiring the patient to pay the difference. HMO dental plans cover fillings at a fixed copay. Original Medicare does not cover routine dental; Medicare Advantage plans may include a dental benefit. Medicaid pediatric dental coverage includes fillings at minimal cost-sharing. Pre-determinations help clarify coverage in advance. HSA and FSA can be used for fillings.
