When it comes to dental restorations, inlays and onlays are two common options that can help preserve the integrity and function of a tooth. These conservative alternatives to full dental crowns are typically used when a tooth has experienced damage or decay but still has sufficient healthy structure to support the restoration. In this article, we will delve into the world of inlays and onlays, exploring when they are both required and their distinct roles in preserving your dental health.

Understanding Inlays and Onlays

Inlays and onlays are dental restorations designed to repair damaged or decayed teeth while preserving as much of the natural tooth structure as possible. They are often crafted from materials like porcelain, composite resin, or gold and can be customized to match the color and shape of your natural teeth.

The Role of Inlays

Inlays are used when the damage or decay within a tooth is confined to the biting surface or the cusps. These restorations fit precisely inside the prepared cavity, similar to a puzzle piece, and are cemented securely in place. Inlays are an excellent choice when the damage doesn’t extend to the tooth’s cusps, making them less invasive than onlays.

The Role of Onlays

Onlays, on the other hand, are more extensive restorations. They are required when the damage or decay extends beyond the cusps and encompasses a larger portion of the tooth. Onlays are designed to cover and protect a more substantial area of the tooth’s surface. They are often referred to as partial crowns because they provide comprehensive coverage and support for the tooth.

When Are They Both Necessary?

While inlays and onlays serve distinct roles in dental restorations, there are situations where both may be required for the same tooth. This typically occurs when a tooth has complex damage or decay that affects multiple surfaces. For example, if a molar has decay on the biting surface (requiring an inlay) and also extends to the sides or cusps (requiring an onlay), a dentist may recommend a combination of both restorations to fully restore the tooth’s function and integrity.

Preserving Tooth Structure and Function

The primary advantage of using inlays and onlays is that they allow dentists to preserve as much natural tooth structure as possible. This minimally invasive approach helps maintain the strength and durability of the tooth while effectively addressing damage or decay. In addition, inlays and onlays provide a superior fit and seal compared to traditional fillings, reducing the risk of future complications.


Inlays and onlays in Papillion NE and other cities or states are versatile dental restorations that play vital roles in preserving your dental health. Inlays are ideal for smaller, more localized damage, while onlays are suited for more extensive restoration needs. However, there are scenarios where a combination of both may be necessary to fully address complex tooth damage while maintaining the tooth’s integrity. These conservative treatments are essential for ensuring long-lasting oral health and minimizing the need for more invasive procedures, such as dental crowns. Your dentist will assess your specific case to determine the most appropriate approach, whether it involves inlays, onlays, or a combination of both to restore your smile.
