Inlays and Onlays: When You Need More Than a Filling But Less Than a Crown
When a tooth is too damaged for a simple filling but not damaged enough to require a full crown, dental inlays and onlays offer an ideal middle-ground solution. At Indira Dental Clinic in Vellore, Dr. Rockson Samuel specializes in these conservative yet durable restorations that preserve more of your natural tooth structure while providing exceptional strength and aesthetics.
What Are Dental Inlays and Onlays?
Inlays and onlays are custom-made restorations that fit precisely into or onto a damaged area of a tooth. They’re sometimes called “indirect fillings” because, unlike traditional fillings that are built directly in your mouth, inlays and onlays are crafted in a dental laboratory and then bonded to your tooth in a separate visit.
Inlays fit within the cusps (bumps) of a tooth, similar to a traditional filling but custom-made outside the mouth.
Onlays extend over one or more cusps of the tooth, covering more surface area than an inlay but less than a crown, which covers the entire visible portion of the tooth.
Think of these restorations on a spectrum:
- Small decay: Traditional filling
- Moderate decay within cusps: Inlay
- Extensive decay involving cusps: Onlay
- Severely damaged tooth: Crown
Why Choose Inlays and Onlays?
At Indira Dental Clinic, we recommend inlays and onlays for many reasons:
1. Preservation of Tooth Structure
Inlays and onlays require less removal of healthy tooth material than crowns, adhering to our philosophy of conservative dentistry—preserving your natural teeth whenever possible.
2. Superior Strength and Durability
Made from strong materials like porcelain or gold, inlays and onlays can last 15-30 years, significantly longer than traditional composite fillings (5-10 years).
3. Precision Fit
Custom-made in a laboratory, these restorations provide a precise fit that helps prevent bacteria from entering and causing new decay.
4. Minimal Expansion/Contraction
Unlike amalgam fillings, inlays and onlays won’t expand and contract with temperature changes, which can prevent cracking of the tooth over time.
5. Aesthetic Excellence
Porcelain or ceramic inlays and onlays match your natural tooth color so well that they’re virtually invisible in your smile.
6. Easier Cleaning
The margins (edges) of inlays and onlays can be placed in areas that are easier to clean, reducing the risk of recurrent decay.
When Are Inlays and Onlays Recommended?
Dr. Samuel might recommend an inlay or onlay in these situations:
- When decay or damage is too extensive for a standard filling
- To replace large, failing fillings
- When a tooth has a crack or fracture that doesn’t warrant a full crown
- For teeth that need strengthening against future fracture
- When optimal aesthetics are desired for visible teeth
- For patients who want longer-lasting alternatives to traditional fillings

The Inlay/Onlay Procedure at Indira Dental Clinic
Getting an inlay or onlay at our Vellore clinic typically involves two visits:
First Appointment (Preparation and Impression)
-
Examination and Planning: Dr. Samuel evaluates your tooth and discusses the best material options for your specific situation.
-
Anesthesia: Local anesthetic is administered to ensure your comfort.
-
Preparation: The decayed or damaged portion of your tooth is removed, and the remaining tooth is shaped to receive the restoration.
-
Impressions: Detailed impressions (molds) of your tooth are taken to create your custom inlay or onlay.
-
Temporary Restoration: A temporary filling is placed to protect your tooth while your custom restoration is being fabricated.
-
Shade Matching: For porcelain or composite restorations, Dr. Samuel carefully matches the color to your natural teeth.
Laboratory Phase (Between Appointments)
Your impressions are sent to our trusted dental laboratory, where skilled technicians craft your custom inlay or onlay using the selected material. This typically takes 1-2 weeks.
Second Appointment (Placement)
-
Removal of Temporary: The temporary filling is removed, and the tooth is cleaned.
-
Try-In: Your new inlay or onlay is tried in to ensure proper fit, bite alignment, and color match.
-
Bonding: Once both you and Dr. Samuel are satisfied, the restoration is permanently bonded to your tooth using special dental cement.
-
Polishing: The restoration is polished to a smooth finish that feels natural in your mouth.
-
Final Check: Your bite is checked once more and any necessary adjustments are made.
Recovery and Aftercare
Most patients experience minimal discomfort after getting an inlay or onlay. Any sensitivity typically resolves within a few days. You can care for your new restoration just as you would your natural teeth:
- Brush twice daily with fluoride toothpaste
- Floss daily, paying special attention to the area around the restoration
- Avoid excessively hard or sticky foods that could damage the restoration
- Wear a night guard if you grind your teeth
- Schedule regular dental check-ups at Indira Dental Clinic
Longevity and Cost Considerations
Durability
With proper care, inlays and onlays are extremely durable:
- Porcelain/ceramic: 15-20+ years
- Composite: 10-15 years
- Gold: 20-30+ years
Cost Factors
The investment for an inlay or onlay is typically higher than for a standard filling but lower than for a crown. Factors that influence cost include:
- Material selected
- Size and complexity of the restoration
- Location of the tooth
- Number of surfaces being restored
During your consultation, we’ll provide a detailed cost estimate and discuss payment options to make your treatment affordable.

Common Questions About Inlays and Onlays
How long does the procedure take?
Each appointment typically takes 45-60 minutes, with 1-2 weeks between appointments for laboratory fabrication.
Are inlays and onlays painful?
The procedure is performed under local anesthesia, so you shouldn’t feel any pain. Some mild sensitivity after the procedure is normal and typically resolves within a few days.
Do inlays and onlays look natural?
Porcelain and composite inlays and onlays are specially crafted to match your natural tooth color so well that most people won’t be able to tell you have them.
How do I know if I need an inlay/onlay instead of a filling or crown?
Dr. Samuel will evaluate the extent of damage to your tooth and recommend the most appropriate restoration. Generally, inlays and onlays are ideal when decay is too extensive for a filling but the tooth still has sufficient healthy structure to avoid needing a crown.
Will my insurance cover inlays and onlays?
Many dental insurance plans provide partial coverage for inlays and onlays, typically considering them a “major” restoration. Our team at Indira Dental Clinic will help you understand your coverage and out-of-pocket costs.
