Porcelain Inlays and Onlays vs. Traditional Fillings: Which Is Better?

Imagine looking at a pristine porcelain tile, perfectly crafted to fit, and now picture that precision applied to our teeth. When we compare porcelain inlays and onlays to traditional fillings, the differences in craftsmanship and durability become evident. Porcelain options are custom-made in a lab, ensuring they fit seamlessly and last longer, while traditional fillings are placed directly into the tooth and may not offer the same longevity or aesthetic appeal. So, how do we decide which is the better choice for maintaining our smile? Let’s explore the key aspects that set these two options apart.

What Are Porcelain Inlays and Onlays

Porcelain inlays and onlays are custom-made dental restorations crafted in a laboratory to precisely fit the contours of a damaged tooth, offering a durable and aesthetically pleasing alternative to traditional fillings. These indirect restorations are created from durable porcelain material that closely mimics the natural tooth. They’re ideal for repairing large and deep cavities without shrinking over time, ensuring a stable, long-lasting solution.

Differences Between Inlays, Onlays, and Fillings

Having knowledge of the benefits of porcelain inlays and onlays, it’s important to compare these restorations with traditional fillings to appreciate their distinct advantages. Traditional fillings are placed directly within a cavity, while inlays and onlays are custom-made in a dental lab, making them indirect restorations.

This fabrication process offers a more precise fit and enhanced durability. Inlays fit between tooth cusps, whereas onlays cover multiple cusps. Unlike traditional fillings that can shrink over time, inlays and onlays are securely bonded, preventing further tooth decay and bacterial seepage. Additionally, they’re more resistant to staining.

The custom-made nature of inlays and onlays guarantees a perfect fit, providing a long-lasting solution for dental restoration.

Benefits of Porcelain Inlays and Onlays

Custom-shaped and meticulously fitted to each tooth, these restorations provide exceptional stability, effectively preventing further decay.

Porcelain inlays and onlays offer a natural appearance, closely mimicking the color and translucency of real teeth. They’re crafted from a durable material that resists stains and wear, ensuring long-lasting results.

Unlike traditional fillings, these restorations fit precisely inside the tooth, reducing the risk of further tooth decay and structural shrinkage over time.

Procedure for Placing Inlays and Onlays

The procedure for placing inlays and onlays involves two meticulous visits to our dental office, guaranteeing both precision and quality in the final restoration. During the first visit, we prepare the tooth by removing any decayed or damaged portions. Afterward, an impression is taken to create a custom-fit restoration. To protect the prepared tooth, a temporary restoration is placed.

In the second visit, we remove the temporary restoration and bond the final restoration onto the tooth. This final restoration is then polished for a seamless, natural look. By adhering to this two-visit process, we guarantee that the inlay or onlay fits precisely, providing a durable and aesthetically pleasing alternative to traditional dental fillings.

Durability and Lifespan

In addition to the meticulous placement process, porcelain inlays and onlays boast a remarkable durability and lifespan, ranging from 5 to 30 years.

These dental restorations resist wear and tear much better than traditional fillings. Unlike amalgam fillings, which can shrink over time, porcelain maintains its integrity without shrinkage, ensuring a precise fit. This precision helps protect the decayed tooth and mimic the strength of natural teeth.

Porcelain inlays and onlays offer lasting protection and stability, often comparable to a dental crown. Their superior durability makes them an excellent choice for patients seeking long-term dental solutions.

With proper care, these restorations can provide enduring support, enhancing the functionality and aesthetics of our smiles.

Care and Maintenance

To ensure the longevity of porcelain inlays and onlays, regular dental check-ups and cleanings are essential. We must take care of the entire tooth surface and adopt basic dental hygiene practices such as brushing and flossing to prevent decay around the restorations.

Porcelain inlays and onlays fit securely inside the tooth without shrinkage or staining, but avoiding hard objects and staining foods is vital. One visit to our office can address any discomfort or sensitivity, ensuring the restorations stay intact.

Refraining from smoking helps maintain their appearance and reduces the risk of gum disease. If you experience any issues, don’t hesitate to contact our office for prompt assessment and repair.

Choosing the Right Option

Maintaining the integrity and health of your teeth requires choosing the right restorative option between porcelain inlays and onlays versus traditional fillings. When considering an inlay or onlay, your dentist will prepare the part of the tooth needing restoration.

Onlays are typically used to fill larger areas, covering multiple cusps. Both restorations are fabricated in a dental lab for a precise fit, necessitating a second visit for placement.

Traditional fillings, however, are directly used to fill cavities in one appointment. If you have questions about inlays or onlays, understanding their durability and ability to maintain tooth structure is essential. Evidence shows that porcelain inlays and onlays offer a more customized, long-lasting solution compared to traditional fillings.


Choosing porcelain inlays and onlays is akin to investing in a tailored suit over an off-the-rack option.

We recently treated a patient whose onlay lasted over 15 years, surpassing the longevity of traditional fillings.

These custom solutions provide a superior fit, durability, and aesthetic appeal. They’re meticulously crafted to seamlessly match your tooth’s structure, ensuring both longevity and a natural appearance.
