Inlays & Onlays in Castle Rock, CO | Oakwood Dental

Oakwood Dental · Castle Rock, CO

When a tooth has too much damage for a simple filling but doesn't need a full crown, an inlay or onlay is the ideal solution — a custom-fitted restoration that is stronger than composite, preserves more natural tooth structure, and looks completely natural. At Oakwood Dental in Castle Rock, CO, we use these precision restorations to save as much healthy tooth as possible.

What Castle Rock Patients Should Know About Inlays & Onlays

Inlays and onlays are often called indirect restorations because they’re fabricated as a single solid piece (rather than built up inside the tooth like a filling). An inlay fits within the cusps of the tooth; an onlay extends over one or more cusps. Both are tooth-colored and bonded permanently — they’re stronger than large fillings and more conservative than full crowns.

Oakwood Dental recommends an inlay or onlay when more than 50% of the biting surface is damaged but the tooth walls are still intact. This scenario is too large for a reliable composite filling yet doesn’t require the full coverage of a crown. Because less natural tooth structure is removed than with a crown, inlays and onlays are often the most conservative restoration choice for moderate-to-large cavities.

The restoration is completed in two visits: preparation and temporary placement at the first, permanent bonding of the custom-milled ceramic piece at the second. Patients from Castle Rock, Franktown, and Douglas County appreciate that the result looks and functions like natural tooth structure. Many dental insurance plans cover inlays and onlays similarly to crowns — at 50% after deductible.

How is an onlay different from a crown?
An onlay covers part of the tooth — typically one to three cusps — while a crown encases the entire tooth. Onlays preserve more natural tooth structure because less enamel is removed during preparation. If the remaining tooth is strong and the damage is limited to the cusps, an onlay is usually preferred.
Are inlays and onlays covered by insurance?
Most PPO plans cover inlays and onlays under major restorative at 50% after deductible, the same as crowns. Oakwood Dental will verify your benefits and provide a cost estimate before starting any work.
How long do inlays and onlays last?
With good home care and routine checkups, ceramic inlays and onlays routinely last 15-20 years or more. They’re more durable than large fillings and resist cracking under chewing pressure better than composite resin in large restorations.
