Across the U.S., a permanent tooth filling usually runs $90–$450 for direct fillings and $650–$1,200 for lab-made inlays or onlays.
Sticker shock at the dentist is no fun. This guide lays out what you’ll pay for a permanent dental repair, why prices swing, and how to lower your bill without cutting corners. You’ll get clear ranges by material, simple math on insurance, and tips to pick the right option for your tooth and wallet.
Permanent Dental Filling Price Range: What Most People Pay
Two broad groups exist. Direct fillings are placed chairside in one visit. Indirect options—porcelain or gold inlays and onlays—are made in a lab and bonded later. Direct work is cheaper and suits small to medium cavities. Indirect work costs more and fits larger defects where strength and shape matter.
| Material/Type | Typical Price | Notes |
|---|---|---|
| Amalgam (silver), one surface | $90–$250 | Durable back-tooth option; darker look. |
| Composite (tooth-colored), one surface | $135–$370 | Matches enamel; may take longer to place. |
| Composite, two–three surfaces | $175–$450 | More time and material raise the fee. |
| Porcelain inlay/onlay | $650–$1,200 | Lab-made; color match and strong fit. |
| Gold inlay/onlay | $800–$1,000+ | Long-wearing; higher metal cost. |
These ranges come from recent national fee snapshots and clinic disclosures. The low end lines up with budget clinics in smaller markets. The high end reflects large metro offices, complex shapes, or high-end ceramics. Direct fillings can also climb when a cavity wraps around corners or dips under the gum.
What Drives The Price For A Filled Tooth
Size And Surfaces
Dentists price direct work by “surfaces.” A tiny pit on one face costs less than a wide repair spanning three sides. Wider prep means more removal, shaping, lining, and finishing. Expect the fee to step up with each added surface.
Tooth Location
Back teeth are harder to access. Saliva control and bite forces are tougher, so visits run longer and materials need extra bulk. Front teeth trade ease of access for color matching; that adds blending time.
Material Choice
Silver blend stands up well but doesn’t match enamel. Composite bonds to the tooth and blends in, but placement takes more steps. Lab-made porcelain or gold needs an impression or scan, a custom piece, then a second visit to bond it in. That lab step drives most of the added cost.
X-Rays, Numbing, And Extras
Most visits include bitewing images to spot decay between teeth, local anesthetic, and a polish. Deep decay might add a liner, a pulp cap, or a build-up before final bonding. If the bite sits high after the jaw wakes up, a quick adjust visit may be included or billed as a minor check.
Geography And Clinic Model
Urban rents and wages push fees up. Boutique offices charge more for time and tech; teaching clinics and public health centers trend lower. Membership plans can trim 10–40% off posted fees in exchange for a yearly enrollment.
Realistic Budgeting: Building A Line-Item Estimate
Ask for a printed treatment plan before work starts. It should show each code, fee, and the plan’s estimate. If you’re paying cash, ask whether a membership plan or day-of-service discount applies. Many offices post a single fee for direct fillings that already folds in numbing and polishes. Lab-made work usually lists separate lines for the temp, the lab fee, and the seat visit.
Sample One-Visit Line Item (Direct Composite)
- Exam (limited or periodic) — sometimes waived if done recently.
- Bitewing X-rays — often once per year or as needed for the area.
- Local anesthetic — part of the procedure fee at many offices.
- Resin filling, one surface — base price that scales by surfaces.
- Polish and bite check — bundled at most clinics.
Sample Two-Visit Line Item (Porcelain Onlay)
- Exam and X-rays for the tooth.
- Prep visit: temp onlay and impression or scan.
- Lab fee for custom ceramic.
- Seat visit: bonding, bite adjustment, and finish.
When A Filling Isn’t Enough
Sometimes decay or cracks leave too little enamel for a direct patch. That’s where an inlay, onlay, or full crown steps in. If the nerve is inflamed or infected, a root canal may be needed before building the tooth back up. Each added step bumps the total. If your dentist flags these risks, ask for two estimates: one for the plan A filling and one for plan B if deeper issues show up mid-procedure.
Ways To Save Without Cutting Quality
Use Preventive Benefits
Twice-yearly cleanings and bitewing X-rays are often fully covered. Catching decay early keeps the repair small and cheap.
Ask About Material Flex
If the tooth is out of sight, a silver blend may be a fine match at a lower fee. If looks matter, a small resin patch can still be modest in cost when caught early.
Bundle Needed Teeth
Fixing two small spots in one appointment can trim repeat set-up time. Some offices price a second filling in the same quadrant a bit lower.
Use Teaching Clinics Or Dental Schools
Supervised students perform care at reduced rates. You trade time for savings. Seats fill up fast near semester starts.
Check Annual Max And Timing
If you’re near the plan’s yearly cap, ask which teeth can wait until the plan renews. Small spots can sometimes be monitored for a short period if they sit in hard enamel and aren’t growing on X-rays.
Material Match: Picking The Right Option
Amalgam
Hard-wearing and cost-effective. Great for molars that carry heavy loads. Color is gray, so most people keep it to back teeth.
Composite Resin
Bonded, tooth-colored, and adaptable. Best for small to mid repairs. Takes a dry field and careful layering to last.
Porcelain Inlay/Onlay
Custom fit and shade. Good when a corner is missing or the top needs added shape beyond a simple patch. Two visits in most offices.
Gold Inlay/Onlay
Time-tested and kind to opposing teeth. Price reflects metal content and lab work. Many choose it for long service on back molars.
What To Ask Before You Say Yes
- Is a direct patch strong enough for this tooth, or do you expect an inlay/onlay?
- How many surfaces are involved today? What pushes the fee to the next tier?
- If decay runs deeper than it looks, what’s plan B and the added range?
- Will the plan pay at in-network rates for this office and material?
- How close am I to the yearly plan cap?
- Can we stage care by urgency if I’m over budget?
Insurance Math: What You’ll Pay Out Of Pocket
Many plans label direct fillings as “basic” care and pay a set share after you meet your deductible. Some plans treat lab-made inlays or onlays as “major,” which means a lower share paid by the plan. Most policies also cap how much they’ll pay across a year, often $1,000–$2,000.
Quick Scenarios
| Scenario | Plan Pays | Your Cost |
|---|---|---|
| $250 one-surface composite; 80% basic after $50 deductible | $160 | $90 (deductible $50 + 20% of $200) |
| $450 three-surface composite; 80% basic after $50 deductible | $320 | $130 |
| $900 porcelain onlay; 50% major after $50 deductible | $425 | $475 |
| $900 gold inlay; plan year max already used | $0 | $900 |
Insurers often follow a “100-80-50” pattern: cleanings at 100%, basic work like direct fillings at around 80%, and major work at about 50%. If you go out of network, the plan may pay less. If you haven’t met the deductible, your share goes up. Many plans reset each year, so timing matters when you need more than one tooth restored.

Sample Cost Walk-Throughs
Small Back-Tooth Cavity, One Surface Composite
Posted fee $250. Your plan pays 80% after a $50 deductible. Deductible applies first, so you pay $50, then 20% of the remaining $200: $40. Total out of pocket $90.
Large Three-Surface Composite On A Molar
Posted fee $450. Plan pays 80% after the deductible. If the deductible is already met, plan pays $360 and you pay $90. If not, plan pays $320 and you pay $130.
Porcelain Onlay For A Cracked Cusp
Posted fee $900. Plan treats this as major at 50% after the deductible. With the deductible met, plan pays $450 and you pay $450. Without it met, plan pays $425 and you pay $475.
When To Choose A Lab-Made Option
Pick an inlay or onlay when the cavity is too wide for a direct patch to hold its shape, a cusp is missing, or the bite will crush a thin corner. These restorations spread bite forces better, which helps prevent fractures on big molars with deep grooves. Direct work still wins for smaller repairs that don’t need extra bulk.
Aftercare And Lifespan
Direct resin often lasts many years with good brushing, flossing, and gentle chewing on ice and hard candy. Silver blend can last even longer on back teeth. Porcelain and gold inlays and onlays commonly serve for a decade or more. Sensitivity is common for a few days. If it lingers or the bite feels high, call the office for a tweak.
Bottom Line Price Bands
If you’re paying cash, plan for $90–$450 for a one-visit repair, depending on material and surfaces. If your case calls for a lab-made piece, budget $650–$1,200. With a typical 100-80-50 plan, many people pay under $150 for small direct work once the deductible is met.
