Inlay & Onlay Restorations in Minnesota
A precise, natural-looking solution for moderate tooth damage.
When a cavity or fracture is too large for a filling but does not require a full crown, an inlay or onlay offers an ideal middle ground. These custom-fabricated restorations are crafted to fit the exact contours of your tooth, preserving more natural structure while delivering outstanding strength and aesthetics.

Inlay & Onlay Restorations in Minnesota
Inlays and onlays are indirect restorations, meaning they are fabricated in a dental lab from an impression of your tooth and then bonded precisely into place. This approach provides a stronger, more durable, and better-fitting result than a direct filling for moderate-sized restorations.
Inlays vs. Onlays: What Is the Difference?
- Inlay Fits within the cusps of a back tooth, restoring the central chewing surface. Used when damage is confined to the area between the cusps.
- Onlay Extends over one or more cusps of the tooth, used when damage involves the biting surface and extends to the outer edges. Also sometimes called a partial crown.
Why Choose Inlays or Onlays?
- Conservative Tooth Preparation More natural tooth structure is preserved compared to a full crown, which requires removing significantly more healthy enamel.
- Superior Fit and Strength Lab-fabricated restorations are precision-made for an exact fit that seals margins more effectively and resists wear better than a direct filling.
- Tooth-Colored Materials Ceramic and composite inlays and onlays blend naturally with surrounding tooth structure for a seamless, invisible result.
- Longevity With good oral hygiene, inlays and onlays can last fifteen to thirty years or more.
The Process
The damaged or decayed portion of the tooth is removed at the first appointment, and an impression is taken to guide lab fabrication. A temporary restoration is placed to protect the tooth while the permanent piece is being made. At the second appointment, the inlay or onlay is carefully bonded and polished for a comfortable, natural result.

Inlay & Onlay Restorations FAQ
- What is the difference between an inlay, an onlay, and a crown?
- An inlay fills the area between the cusps of a back tooth, an onlay extends over one or more cusps, and a crown covers the entire visible tooth. Inlays and onlays are used when damage is too large for a filling but not severe enough for a crown. This lets Dr. Miller preserve more healthy enamel, consistent with her minimally invasive philosophy.
- Are inlays and onlays better than fillings?
- For larger restorations, yes. Lab-made ceramic or composite inlays and onlays fit more precisely, seal the margins better, and resist wear longer than a large direct filling. For small cavities, often detected early with DIAGNOdent laser cavity detection, a tooth-colored composite filling remains the simplest and most conservative choice. Valley View Dental does not place amalgam fillings; all fillings and restorations are mercury-free.
- How long does an inlay or onlay procedure take?
- Inlays and onlays typically take two appointments. At the first visit, Dr. Miller removes the decay or damaged area, takes digital impressions with no impression putty, and places a temporary restoration. The second visit, usually one to two weeks later, is when the finished restoration is bonded, checked against your bite, and polished.
- Are inlays and onlays noticeable?
- No. Tooth-colored ceramic and composite inlays and onlays are matched to your natural tooth shade and are virtually invisible in everyday conversation. Because they are completely metal-free, they do not show a dark outline or gray tint. Many patients choose them to replace old amalgam fillings for both appearance and peace of mind.
- Do inlays or onlays hurt?
- The procedure is done under local anesthetic and is comfortable for most patients. Mild sensitivity to temperature or chewing pressure is normal for a few days after placement and typically fades on its own. Valley View Dental also offers NuCalm for drug-free relaxation and Avazzia microcurrent therapy, which many patients report helps numbness wear off faster.
- Are inlays and onlays covered by insurance?
- Many dental insurance plans cover inlays and onlays because they are restorative procedures, though coverage amounts vary by plan. Valley View Dental is in-network with Delta Dental and accepts many PPO plans, and the team can review your benefits before treatment. Financing through CareCredit, Cherry, and Alphaeon is also available.
