Durable, Precise Restorations for Damaged Teeth
When a tooth is too damaged for a filling but not damaged enough to require a full crown, inlays and onlays offer the perfect balance between strength and conservation. At North Arbor Dental, we use high-quality ceramic and digital precision to craft these restorations with long-lasting results and a seamless fit.
As a modern dentist in Kitchener Waterloo, we offer digitally designed inlays and onlays that preserve healthy tooth structure while restoring full chewing function and aesthetics.
What Are Inlays and Onlays?
Inlays and onlays are custom-made restorations used to repair moderately damaged or decayed teeth — typically molars or premolars. They are sometimes called indirect fillings because they are fabricated outside the mouth and then bonded into place.
- Inlays fit within the grooves of the tooth (like a large filling)
- Onlays cover one or more cusps of the tooth (like a partial crown)
These restorations are often made from durable ceramic or porcelain and offer a more precise, long-term alternative to traditional composite fillings.
When Are Inlays or Onlays Recommended?
Inlays and onlays may be ideal when:
- A tooth has too much damage for a filling, but not enough for a crown
- You want to avoid the more invasive prep required for full crowns
- You have a fractured or heavily restored tooth
- An existing large filling needs to be replaced
- You want a stronger and longer-lasting alternative to composite
We’ll use digital diagnostics to assess your tooth and determine whether an inlay, onlay, or a crown is the most appropriate option.
Benefits of Inlays and Onlays
- Strength and durability — more resilient than standard fillings
- Precision fit — custom-designed to your bite using digital scanning
- Natural look — tooth-colored materials blend beautifully with enamel
- Conservative treatment — preserves more natural tooth structure than a crown
- Biocompatible materials — metal-free, safe, and long-lasting
We use the same advanced SprintRay technology for the design and fabrication of inlays and onlays.
What to Expect During Treatment
Most inlay or onlay treatments require just one or two visits, depending on the material and fabrication method.
Step 1: Tooth Preparation
We remove decay or damage and prepare the site with minimal impact on healthy enamel.
Step 2: Digital Scan
We capture a digital impression of your tooth for precise design — no gooey molds.
Step 3: Fabrication
Your inlay or onlay is created from high-strength ceramic. In some cases, we may use in-office SprintRay technology for same-day placement.
Step 4: Placement and Bonding
The restoration is securely bonded to your tooth and polished for a seamless, comfortable finish.

Are inlays and onlays better than fillings?
They’re often more durable and longer-lasting than large composite fillings, especially for molars under heavier chewing force. But it depends on your clinical assessment and bite.
Do inlays and onlays hurt?
No. We numb the area and use minimally invasive prep. Most patients find the experience comfortable.
How long do they last?
With good care, inlays and onlays can last for many years, and their longevity depends on factors like bite forces, oral hygiene, and the amount of remaining tooth structure.
Is it better to get an onlay than a crown?
If enough healthy tooth remains, an onlay is a more conservative option. We'll recommend what's best for your long-term health.
Will insurance cover this treatment?
Most dental insurance plans cover inlays and onlays similarly to crowns or fillings, depending on your policy. We’ll provide a detailed estimate before treatment.
