Sometimes, a tooth problem falls in the “in-between” category — too big for a simple filling but not severe enough to require a full crown. That’s where dental inlays and onlays come in. These custom-made restorations are a powerful way to repair damage, strengthen your teeth, and protect your smile — all while preserving more of your natural tooth structure.
At Canyon Creek Dental in Billings, MT, Dr. Pearson and Dr. Clark offer expertly crafted dental inlays and onlays designed to match your natural teeth perfectly. Here’s everything you need to know about these versatile restorations — from how they work to when they’re needed, what they cost, and how they compare to other options.
What Are Dental Inlays and Onlays?
Dental inlays and onlays — sometimes called “partial crowns” — are custom restorations used when a tooth has moderate decay or damage that can’t be fixed with a filling but doesn’t require a full crown.
- Inlays fit inside the cusps (the raised edges) of a tooth.
- Onlays extend over one or more cusps, offering broader coverage.
Both are made from durable materials like porcelain, composite resin, or gold and are custom-designed to restore the tooth’s natural function, strength, and appearance.
When Are Inlays or Onlays Recommended?
Dr. Pearson or Dr. Clark may recommend an inlay or onlay if:
- Your cavity or decay is too large for a filling
- Your tooth is cracked or weakened but doesn’t need a full crown
- You want a long-lasting, natural-looking solution
- You want to preserve as much natural tooth as possible
Inlays and onlays are especially beneficial for restoring molars and premolars — teeth that handle heavy chewing forces.
Inlays vs. Onlays: What’s the Difference?
The main difference between inlays and onlays is the amount of coverage:
| Restoration | Coverage Area | Best For |
|---|---|---|
| Inlay | Fits inside the tooth’s cusps | Moderate decay or damage that doesn’t extend to the edges |
| Onlay | Extends over one or more cusps | Larger areas of damage, including cusp involvement |
Inlays are slightly less invasive, but onlays offer more protection when more of the tooth is affected. Your dentist will recommend the right solution after evaluating your tooth.
The Dental Inlay/Onlay Procedure: What to Expect
Getting an inlay or onlay usually takes two visits, though some cases can be completed in one visit using advanced technology like CEREC.
1. Preparation
The damaged or decayed area is removed, and the tooth is carefully shaped to ensure a secure fit for the restoration.
2. Impression or Digital Scan
An impression or 3D digital scan is taken of your tooth. This is sent to a dental lab where your custom inlay or onlay is crafted.
3. Temporary Restoration
A temporary restoration is placed to protect your tooth while your permanent one is being made.
4. Final Placement
Once your restoration is ready, it’s bonded securely to your tooth. Our dental team will check your bite and make final adjustments.
The result? A strong, natural-looking tooth that functions just like the original.
Cost Comparison: Inlays, Onlays, Fillings, and Crowns
One of the biggest questions patients have is about cost. Here’s how inlays and onlays compare to other common restorations:
| Treatment | Purpose | Estimated Cost | Lifespan |
|---|---|---|---|
| Filling | Small cavities | $150 – $350 per tooth | 5 – 10 years |
| Inlay | Moderate decay inside cusps | $650 – $1,200 per tooth | 10 – 20 years |
| Onlay | Larger decay extending over cusps | $800 – $1,500 per tooth | 10 – 20 years |
| Crown | Severe damage requiring full coverage | $1,000 – $1,800 per tooth | 10 – 20+ years |
These ranges are estimates. Contact Canyon Creek Dental for a personalized treatment plan.
