Inlays & Onlays in Naperville, IL
When a tooth has too much damage for a standard filling but doesn't need a full crown, an inlay or onlay offers the ideal middle ground. These custom-made restorations repair moderate decay, cracks, or fractures while preserving as much of your natural tooth structure as possible. At , we use durable, tooth-colored materials for a restoration that looks and feels natural.
What they are
Custom-made restorations that fit inside or over the cusps of a damaged tooth — stronger than fillings, more conservative than crowns.
Who they're for
Patients with moderate decay, cracked cusps, or large old fillings that need replacement, where enough healthy tooth remains.
How we help
Precise preparation, custom fabrication in durable tooth-colored materials, and a secure, long-lasting fit that preserves your natural tooth.
Have a cracked tooth or failing filling? An inlay or onlay may save your tooth without needing a full crown.
What's the Difference Between an Inlay and an Onlay?
Dental Inlay
- Fits within the cusps (raised points) on the chewing surface of a tooth
- Replaces a standard filling when the damage is too extensive for composite alone
- Custom-made to precisely fill the prepared area
- Ideal for moderate decay or damage on the tooth's biting surface
Dental Onlay
- Extends over one or more of the tooth's cusps, covering a larger area
- Sometimes called a "partial crown" because it replaces more tooth structure than an inlay
- Used when the damage is too extensive for an inlay but a full crown isn't necessary
- Preserves more natural tooth than a crown while providing excellent protection
Materials and Benefits
Material Options
- Porcelain/ceramic: The most popular choice — matches your natural tooth color for a seamless appearance
- Composite resin: Tooth-colored option that bonds well to the tooth structure
- Gold: Extremely durable and long-lasting, preferred by some patients for back teeth
- Dr. Brammeier will recommend the best material based on the tooth's location, your bite, and your aesthetic preferences
Key Benefits
- Preserves tooth structure: Less of your natural tooth is removed compared to a full crown
- Durability: Custom-made materials are stronger and last longer than standard fillings
- Natural appearance: Tooth-colored options blend seamlessly with surrounding teeth
- Precise fit: Custom fabrication means a tighter seal against bacteria
- Strengthens the tooth: Bonds to the tooth and reinforces its structure
How the Procedure Works
Procedure Steps
- Preparation: The decayed or damaged portion of the tooth is carefully removed and the tooth is shaped to hold the restoration
- Impression: A precise mold of your tooth is taken and sent to a dental laboratory for custom fabrication
- Temporary: A temporary restoration protects the tooth while your custom inlay or onlay is being made
- Placement: At your follow-up visit, the custom restoration is bonded securely to your tooth and polished for a perfect fit
What to Know
- The procedure typically requires two visits spaced about 2 weeks apart
- Local anesthesia keeps you comfortable during preparation
- Same-day restorations may be available for select cases — ask Dr. Brammeier if this option is right for you
- The bonding process creates a tight seal that helps prevent future decay underneath the restoration
- Most patients experience little to no discomfort after the procedure

Frequently Asked Questions
An inlay fills the area between the cusps (bumps) on a tooth's chewing surface. An onlay covers one or more cusps, providing more extensive coverage. A crown covers the entire visible portion of the tooth. Dr. Brammeier recommends the most conservative option that will effectively restore the tooth.
With good oral hygiene and regular dental visits, inlays and onlays can last 10 to 30 years — often longer than traditional fillings. Their durability depends on the material used, the tooth's location, your bite forces, and how well you care for your teeth.
For moderate damage, yes. Inlays and onlays are custom-made in a lab for a more precise fit, they're made from stronger materials, and they actually strengthen the remaining tooth structure. Standard fillings are better suited for small areas of decay.
Absolutely. Porcelain and composite inlays and onlays are color-matched to your surrounding teeth, making them virtually invisible. Most people won't be able to tell you have a restoration.
No. Local anesthesia numbs the area during preparation, so you won't feel pain. Most patients report the experience is similar to getting a filling. Any post-procedure sensitivity is typically mild and short-lived.
The cost falls between a standard filling and a full crown, varying based on the material chosen and the size of the restoration. Most dental insurance plans cover inlays and onlays as a restorative procedure. We provide a detailed estimate before treatment and offer financing options.
Yes, this is actually one of the most common reasons for getting an inlay or onlay. When a large old filling cracks, wears out, or develops decay around its edges, upgrading to a custom inlay or onlay provides a stronger, longer-lasting restoration.
Care for them exactly as you would your natural teeth — brush twice daily, floss daily, and visit Dr. Brammeier for regular checkups. Avoid biting on extremely hard objects like ice or hard candy, and consider a night guard if you grind your teeth.
