The Benefits of Using Inlays and Onlays When Filling a Cavity

Posted on: 21 September 2023

Dental cavities can be quite bothersome and cause a lot of pain, discomfort, and inconvenience. The good news is that modern dentistry has several options for filling cavities. Two of the most common restoration methods used by dentists today are inlays and onlays. While both techniques involve restoring tooth structure, they differ in their approach. Explore the benefits of using inlays and onlays when filling a cavity.


Inlays and onlays are made from durable materials such as ceramics, composite resins, and gold. As a result, they last much longer than traditional fillings. They exhibit outstanding durability and can endure the rigors of chewing and biting forces with exceptional resilience.

Precision Restoration

One of the main benefits of using inlays and onlays is their accurate restoration. Unlike traditional fillings, they are created in dental labs and are custom-designed to fit precisely into the cavity. This precision allows for better sealing of the cavity, protecting it from bacteria and plaque buildup.

No Shrinking

Traditional fillings shrink over time, causing the filling to contract from the surrounding tooth structure. The cavity gradually opens up, making it susceptible to bacterial invasion, leading to decay. In contrast, inlays and onlays do not shrink, reducing the need for frequent replacements.

Aesthetic Appeal

Inlays and onlays come in a variety of materials that blend in with your natural teeth and are a good option for visible locations, such as the front teeth. They help restore your natural smile without sacrificing durability or functionality.

Preserves Natural Tooth Structure

Inlays and onlays are dental restorations that offer the benefit of requiring less removal of natural tooth structure. Unlike traditional fillings, which often necessitate the removal of more tooth structure, inlays and onlays are designed to preserve as much of the natural tooth as possible. This preservation of tooth structure promotes better long-term tooth health, as it helps to maintain the integrity and strength of the tooth. By minimizing the amount of tooth structure that needs to be removed, inlays and onlays provide a conservative and effective treatment option for restoring damaged or decayed teeth.

There are many benefits to using inlays and onlays when restoring a cavity. From their accurate restoration techniques to their long-lasting and aesthetic appeal, these restorations offer numerous advantages over traditional fillings. In addition, they preserve more of the natural tooth structure, enhancing the overall health and longevity of the tooth.
