Most people are familiar with the two most common ways to restore a damaged tooth — fillings for smaller cavities and dental crowns for more significant damage. But there’s a middle ground that often gets overlooked, and for many patients in Bellflower, CA, it turns out to be the most appropriate solution. Inlays and onlays sit between these two options, offering a precise, durable, and conservative way to restore teeth that have sustained moderate damage without removing more natural tooth structure than necessary.
At California Dental Group, we offer custom inlays and onlays for patients who need more than a filling can provide but don’t yet require a full crown. Call us at 800-407-0161 to set up an appointment and find out whether this treatment is the right fit for your tooth.
Understanding the Difference Between Inlays and Onlays
Inlays and onlays are both indirect restorations, meaning they’re custom-fabricated outside the mouth in a dental lab and then bonded to the tooth — unlike a direct filling, which is shaped and placed during a single appointment. The distinction between the two comes down to how much of the tooth’s surface they cover.
An inlay fits within the grooves and contours of the tooth’s biting surface, restoring the area between the cusps without extending over them. It’s the right choice when damage is confined to the inner portion of the tooth.
An onlay covers a larger area and extends over one or more of the tooth’s cusps. When decay or damage reaches beyond the central portion of the tooth but still doesn’t compromise the entire structure, an onlay provides the coverage needed without resorting to a full crown.
Both restorations are custom-made to fit the exact shape and contours of the tooth, and both are available in tooth-colored materials like porcelain or composite resin that blend seamlessly with your natural teeth.
Why the Conservative Approach Matters
One of the most significant advantages of inlays and onlays is how much healthy tooth structure they allow your dentist to preserve. A full crown requires reshaping the entire tooth — removing enamel from all sides to make room for the cap that fits over it. While crowns are absolutely the right solution in many situations, using one when the damage doesn’t warrant it means sacrificing healthy tooth structure unnecessarily.
Inlays and onlays require only the removal of the damaged or decayed portion of the tooth. The restoration is then bonded precisely to the prepared area, reinforcing the tooth without altering the parts that are still intact. For patients who value preserving as much of their natural tooth as possible, this distinction matters.
What the Process Looks Like
Getting an inlay or onlay at California Dental Group typically takes two appointments. At the first visit, your dentist will remove the damaged portion of the tooth and take an impression of the prepared area. That impression is sent to a dental lab where your custom restoration is crafted to fit your tooth exactly. A temporary covering is placed to protect the tooth in the meantime.
At your second appointment, the temporary is removed, and the permanent inlay or onlay is checked for fit, adjusted as needed, and bonded securely to the tooth. Once polished, the restoration is virtually indistinguishable from the surrounding natural tooth surface.
Long-Lasting Results with Proper Care
Inlays and onlays are known for their durability. Because they’re fabricated from high-quality materials in a controlled lab setting and bonded with strong dental adhesives, they tend to hold up well under the daily forces of chewing. With regular brushing, flossing, and routine dental visits, an inlay or onlay can last for many years before needing any attention.
