Dental Inlays & Onlays in Arlington Heights, IL
When a tooth has too much damage for a simple filling but doesn't need a full crown, an inlay or onlay is often the right answer. Dr. Debbie Rhie offers dental inlays and onlays in Arlington Heights as a conservative, tooth-preserving approach to restoring back teeth — protecting what's healthy while repairing what's damaged. Arlington Comfort Dental is welcoming new patients, accepts Delta Dental, Blue Cross Blue Shield, and several other major insurance plans, and offers Monday and Wednesday evening appointments for patients who work during the day.
What Are Dental Inlays and Onlays?
Inlays and onlays are custom-made restorations crafted outside the mouth — in a dental lab — and then bonded permanently to the damaged tooth. Because they are made to fit your tooth precisely, they tend to be stronger and longer-lasting than a filling placed directly in the chair. They're part of the broader family of restorative dentistry options Dr. Rhie uses to help patients keep their natural teeth for as long as possible.
Inlays vs. Onlays — What's the Difference?
The distinction is straightforward. An inlay fits within the cusps — the raised points — of a back tooth, filling in the space where decay or damage has occurred without covering the outer edges. An onlay extends further, covering one or more of the tooth's cusps along with the inner surface. Think of an onlay as a partial crown: it restores more of the tooth's chewing surface while still preserving healthy structure that a full crown would require removing.
What Materials Are Used? (Porcelain, Composite, Gold)
Inlays and onlays can be made from three main materials, each with its own strengths:
- Porcelain — The most popular choice for visible back teeth. Porcelain inlays blend naturally with tooth color and are highly durable. This is often what patients mean when they ask about a porcelain inlay in Arlington Heights.
- Composite resin — A tooth-colored option that bonds well to natural tooth structure. Slightly less durable than porcelain over the long term but a solid fit for many patients.
- Gold — Exceptionally strong and long-wearing. Gold inlays and onlays are a reliable choice for molars that handle heavy chewing forces, though they are less cosmetically discreet.
Dr. Rhie will help you weigh the options based on where the tooth is, how much chewing load it carries, and your personal preferences.
Benefits of Choosing an Inlay or Onlay
Why Choose an Indirect Restoration Over a Filling?
A traditional filling is placed directly into the tooth in a single visit and is a good solution for smaller areas of decay. But when the damage covers a larger portion of the chewing surface, a direct filling may not hold as well over time. An indirect restoration like an inlay or onlay is fabricated to precise dimensions, bonds more firmly to the tooth, and is designed to withstand years of daily use. Patients often find that an inlay or onlay feels and functions more like a natural tooth than a large filling does.
Inlays & Onlays vs. Dental Crowns — How Do You Know Which One You Need?
A dental crown covers the entire visible surface of a tooth, which means some healthy tooth structure must be removed to make room for it. That trade-off is sometimes necessary — for teeth that are severely cracked, weakened after a root canal, or too damaged for a partial restoration. An inlay or onlay, by contrast, covers only the area that actually needs repair. If your tooth still has a solid, healthy foundation, an inlay or onlay lets Dr. Rhie restore the damaged section while leaving the rest of your natural tooth intact. In general, the less healthy tooth structure that needs to be removed, the better — which is why inlay and onlay treatment in Arlington Heights IL is often the preferred first step when the damage falls in that middle range between a filling and a crown.
What to Expect at Arlington Comfort Dental
The Inlay & Onlay Process, Step by Step
Most inlay and onlay treatments at Arlington Comfort Dental are completed over two comfortable appointments:
- First visit:** Dr. Rhie removes the damaged or decayed portion of the tooth, takes precise impressions, and places a temporary restoration to protect the tooth while your custom inlay or onlay is being made.
- Lab fabrication:** Your restoration is crafted to match the exact shape and bite of your tooth.
- Second visit:** The temporary is removed, and Dr. Rhie bonds your permanent inlay or onlay into place, checks your bite, and makes any minor adjustments needed.
The process is straightforward and unhurried. If you have questions at any point, Dr. Rhie takes the time to walk you through what's happening and what to expect next. Keeping up with dental exams and cleanings after your restoration helps protect both the inlay or onlay and the surrounding tooth long-term.

Are inlays and onlays covered by dental insurance?
Many dental insurance plans, including Delta Dental and Blue Cross Blue Shield, provide partial coverage for inlays and onlays as restorative procedures. The exact benefit depends on your specific plan and annual maximum. Our team can help review your coverage before treatment so you have a clear picture of your out-of-pocket costs.
How long do inlays and onlays last?
With proper care, inlays and onlays are designed to last many years — often a decade or more. Porcelain and gold options are especially durable. Keeping up with regular exams and cleanings helps protect your restoration and the surrounding tooth structure over time.
What happens if I skip treatment for a damaged tooth?
A tooth with significant decay or damage will not heal on its own. Left untreated, the damage can spread deeper into the tooth, potentially requiring a root canal or extraction. Addressing the problem early with an inlay or onlay is almost always the more conservative — and more affordable — path.
