A Conservative Way to Restore Damaged Teeth
Inlays and onlays are custom-made restorations that repair teeth affected by decay or damage that is too extensive for a standard filling, but not severe enough to require a full crown. Often called “partial crowns,” these restorations are fabricated outside the mouth and bonded into place, preserving more of your natural tooth structure while restoring strength, function, and appearance.
What are
Inlays and Onlays?
Inlays and onlays are custom restorations designed to fit precisely within a prepared area of a tooth. An inlay fits inside the cusps, or raised points, on the chewing surface of a tooth. An onlay extends over one or more of those cusps, covering a larger portion of the tooth. Both are typically made from porcelain, ceramic, composite resin, or gold and are bonded securely to the remaining tooth structure.
Inlays and onlays may be used to treat:
- Moderate tooth decay
- Fractured or cracked teeth
- Worn chewing surfaces
- Large or failing existing fillings
- Teeth too damaged for a filling but not requiring a crown
- Cosmetic concerns on back teeth

The Inlay and Onlay Process Process
Initial Consultation
Your tooth is examined and imaged to determine the extent of decay or damage and whether a partial restoration is appropriate.
Tooth Preparation
Decayed or damaged tissue is removed, and the tooth is shaped to receive the restoration.
Impressions or Digital Scanning
Precise impressions or digital scans capture the shape of the prepared tooth and your bite.
Fabrication and Temporary Coverage
Your custom restoration is created while a temporary covering protects the tooth, when needed.
Placement and Bonding
The inlay or onlay is checked for fit and color, then bonded into place and polished for a smooth, natural finish.
A Middle Ground Between Fillings and Crowns
Many patients choose inlays and onlays because they restore a damaged tooth without the more extensive reshaping a full crown requires. This conservative approach maintains natural tooth structure while delivering the strength and longevity needed for everyday chewing, making it an appealing option for back teeth that carry heavy bite forces.
FAQs about Inlays and Onlays
An inlay fits within the cusps on the chewing surface of a tooth, while an onlay extends over one or more cusps to cover a larger area.
With good oral hygiene and regular dental visits, inlays and onlays can last many years.
Porcelain and composite restorations are matched to your natural tooth color and blend in with the surrounding teeth.
The tooth is numbed during treatment, and most patients report only mild sensitivity afterward.
Traditional inlays and onlays typically require two visits, though same-day options may be available in some cases.
Brush and floss daily, avoid chewing hard objects, and keep up with routine dental checkups.
