Inlays and Onlays
 If you have a damaged or decayed tooth that needs more than a filling but less than a full crown, inlays and onlays in Kirkland, WA offer an ideal middle-ground solution at Cooley Smiles. These custom-crafted restorations are designed to fit precisely into or onto the affected area of your tooth, restoring its strength and natural appearance. Our team uses high-quality materials and careful attention to detail to deliver results that look, feel, and function like a healthy natural tooth.
Inlays and onlays are a key part of our restorative dentistry services. They are sometimes called indirect fillings because they are fabricated outside of the mouth and then bonded into place, unlike traditional fillings that are placed directly. This approach allows for a more precise fit and often greater durability, making inlays and onlays an excellent long-term investment in your dental health.
Whether you are dealing with a cracked tooth, a large cavity, or an old restoration that needs replacement, our Kirkland dental team can evaluate your tooth and help you determine if an inlay or onlay is the right choice.

Understanding Inlays and Onlays
 Inlays and onlays are custom dental restorations used to repair teeth that have moderate damage or decay. They are crafted from durable materials such as porcelain, composite resin, or gold, and are bonded to the affected tooth with a strong dental adhesive. The result is a restoration that reinforces the tooth’s structure while blending naturally with your smile.
The difference between an inlay and an onlay comes down to how much of the tooth needs to be restored. An inlay fits within the cusps (the raised points) of a back tooth, filling the space between them much like a traditional filling but with greater precision and strength. An onlay extends over one or more of the cusps, covering a larger portion of the biting surface. Both options preserve significantly more natural tooth structure than a full dental crown, which makes them a more conservative choice when the damage is not severe enough to warrant full coverage.
Who Is a Good Candidate?
You may be a good candidate for an inlay or onlay if you have a cavity too large for a standard filling to support reliably, a cracked or fractured tooth that still has enough healthy structure remaining, an old large filling that needs to be replaced, or mild to moderate damage on a back tooth. Our team examines your tooth carefully and uses advanced imaging technology to assess the extent of the damage before recommending the best approach. If the damage is too extensive for an inlay or onlay, we may recommend a full crown instead. For patients with cracked teeth, an onlay can often provide the reinforcement needed to prevent further damage.
Inlays and Onlays vs. Fillings and Crowns
Traditional fillings work well for small cavities, but they can weaken a tooth when the cavity is large. Inlays and onlays address this gap by providing a custom-fitted restoration that distributes biting forces more evenly across the tooth. Compared to a full crown, an inlay or onlay preserves more of your natural enamel because less of the tooth needs to be reshaped during preparation. This conservative approach often leads to better long-term outcomes for the tooth. Our Kirkland team takes the time to evaluate where each option fits best so you receive the most appropriate and lasting restoration.

The Inlay and Onlay Process, Step by Step
The process for receiving an inlay or onlay typically involves two visits to our Kirkland office. Here is what to expect at each stage.
First Visit: Preparation and Impressions
During your first appointment, our dentist numbs the area and removes the damaged or decayed portion of the tooth. The remaining tooth structure is shaped to create a stable foundation for the restoration. We then take a precise impression of the prepared tooth, which is sent to a dental laboratory where your custom inlay or onlay is fabricated. A temporary restoration is placed to protect the tooth while your permanent piece is being made.
Fabrication at the Lab
At the laboratory, skilled technicians craft your inlay or onlay from the material selected during your consultation. Porcelain and composite resin options are matched to the shade of your natural teeth for a seamless appearance. The fabrication process typically takes one to two weeks.
Second Visit: Bonding and Final Fit
Once your restoration is ready, you return to our office for placement. We remove the temporary, clean the prepared tooth, and try in the inlay or onlay to check the fit. After confirming that the fit is precise and the bite is comfortable, we bond the restoration permanently using a strong dental adhesive. The surface is then polished for a smooth, natural finish.
The total timeline from first visit to final placement is usually two to three weeks. If you feel nervous about the process, our team offers sedation dentistry options to keep you comfortable at both appointments.
Benefits of Inlays and Onlays
Inlays and onlays offer a set of advantages that make them a smart choice for patients with moderate tooth damage. Here is what you gain by choosing this type of restoration.
Durability is one of the most significant benefits. Because inlays and onlays are fabricated in a lab from solid materials, they tend to be stronger and longer-lasting than large direct fillings. Porcelain and high-quality composite restorations can last 15 to 30 years with proper care, making them a reliable long-term investment.
Conservation of tooth structure sets inlays and onlays apart from full crowns. When a tooth has enough healthy structure remaining, preserving it is always the better approach. Less removal of natural enamel means the tooth retains more of its original strength, and future treatment options remain open if the tooth ever needs additional work down the road.

Natural Appearance – Porcelain and tooth-colored composite options are matched to your natural shade for a restoration that blends in seamlessly

Precise Fit – Lab fabrication allows for an exact fit that reduces the risk of gaps, which helps prevent bacteria from entering under the restoration

Strengthens the Tooth – Unlike large fillings that can weaken a tooth, inlays and onlays reinforce the remaining structure and distribute biting forces evenly

Stain Resistance – Porcelain inlays and onlays resist staining better than composite fillings, helping your smile stay bright over time |
For patients who want a restoration that combines strength, aesthetics, and a conservative approach, inlays and onlays deliver on all three fronts.

Because inlays and onlays are custom-fabricated, they are typically priced between a standard filling and a full crown.

Frequently Asked Questions
What is the difference between an inlay and an onlay?
An inlay fits within the cusps of a tooth, restoring the area between the raised points on the biting surface. An onlay extends over one or more cusps, covering a larger portion of the tooth. Both are custom-fabricated and bonded into place for a precise, durable result.
How long do inlays and onlays last?
With proper care, porcelain and high-quality composite inlays and onlays can last 15 to 30 years. Longevity depends on the material used, the location of the tooth, and your oral hygiene and dietary habits. Regular dental visits help our team monitor the restoration over time.
Is getting an inlay or onlay uncomfortable?
The procedure is performed with local anesthesia, so you should feel little to no discomfort during either appointment. Most patients find the experience very similar to receiving a standard filling. Sedation options are available for patients who experience dental anxiety.
Why would I choose an inlay or onlay instead of a crown?
An inlay or onlay preserves more of your natural tooth structure because less of the tooth needs to be reshaped. When a tooth has enough healthy enamel remaining, a more conservative restoration is generally the better long-term choice. Our team evaluates your specific situation to recommend the most appropriate option.
What materials are used for inlays and onlays?
Common materials include porcelain, composite resin, and gold. Porcelain and composite resin are matched to your natural tooth color for a seamless appearance. Gold is extremely durable and is sometimes preferred for back teeth that bear heavy biting forces. Our team will help you select the material that best fits your needs.
Does dental insurance cover inlays and onlays?
Many dental insurance plans cover a portion of inlay and onlay treatment, particularly when the restoration is needed to repair decay or structural damage. Coverage varies by plan, so contact our office or visit our insurance and payments page to verify your specific benefits before treatment.
How many visits does it take to get an inlay or onlay?
The process typically requires two visits. At the first visit, the tooth is prepared and an impression is taken. Your custom restoration is fabricated at a dental lab over one to two weeks. At the second visit, the inlay or onlay is bonded into place and polished for a final fit.
