When it comes to repairing damaged teeth, fillings and crowns are often the first solutions that come to mind. However, there’s a lesser-known, yet highly effective, option that bridges the gap between these two common procedures: inlays and onlays. These restorative treatments offer a conservative and aesthetically pleasing approach to addressing tooth decay or damage while preserving as much of your natural tooth structure as possible.
Inlays and onlays are custom-made fillings crafted from composite resin or porcelain materials. Unlike traditional fillings, which are applied directly to the tooth, inlays and onlays are fabricated in a dental laboratory and then bonded to the tooth, providing a more durable and precise restoration. This approach offers a less invasive alternative to crowns, which require the removal of a significant portion of the natural tooth structure.

What Are Inlays and Onlays?
Think of inlays and onlays as the “Goldilocks” of restorative dentistry – they offer a solution that’s not too invasive like a crown, yet more substantial and durable than a filling. These custom-made restorations provide a perfect fit for your tooth, restoring its function and enhancing its appearance.
Let’s delve into the specifics of each type:
Inlays: Restoring the Inner Tooth Structure
An inlay is used when the damage is confined to the central portion of the tooth, within the cusps (the pointed biting surfaces). It fits snugly within the contours of the tooth, restoring its structural integrity and function. Think of it as a puzzle piece that seamlessly integrates with the existing tooth structure.
Onlays: Repairing a Larger Surface Area
An onlay, sometimes referred to as a partial crown, is used when the damage extends to one or more cusps of the tooth. It covers a larger surface area than an inlay, providing additional support and strength to the affected tooth. Essentially, an onlay acts as a cap for the damaged portion of the tooth, restoring its form and function.
The Advantages of Tooth-Coloured Inlays and Onlays
Inlays and onlays offer several advantages over traditional fillings and crowns:
- Preservation of Tooth Structure: They require minimal removal of healthy tooth structure compared to crowns.
- Durability and Longevity: Inlays and onlays are crafted from strong, wear-resistant materials that can withstand biting forces.
- Natural Appearance: They can be colour-matched to your natural teeth, creating a seamless and aesthetically pleasing restoration.
- Improved Oral Health: The precise fit of inlays and onlays helps prevent bacteria from accumulating, promoting better oral hygiene.
When Are Inlays and Onlays Recommended?
Inlays and onlays are versatile restorative options suitable for a range of dental concerns.
Addressing Moderate Tooth Decay or Damage
When tooth decay or damage extends beyond what a filling can effectively address but doesn’t warrant a full crown, inlays and onlays provide an ideal solution. They effectively restore the structural integrity of the tooth while preserving as much healthy tissue as possible.
Preserving Healthy Tooth Structure
One of the significant advantages of inlays and onlays is their conservative nature. Unlike crowns, which require the removal of a significant portion of the natural tooth, inlays and onlays preserve healthy tooth structure. This helps maintain the tooth’s strength and vitality in the long term.
Enhancing the Strength and Durability of Teeth
Inlays and onlays provide reinforcement to weakened or damaged teeth. They can help prevent further fractures or cracks, ensuring the longevity of the natural tooth. This is particularly beneficial for teeth that have undergone root canal treatment, as they can become more brittle over time.
Improving the Aesthetics of Your Smile
Tooth-coloured inlays and onlays blend seamlessly with your natural teeth, creating an aesthetically pleasing restoration. They can address cosmetic concerns such as discolouration, chips, or cracks, enhancing the overall appearance of your smile.

The Procedure
Getting an inlay or onlay is a meticulous process designed to ensure a precise fit and optimal outcome. While the exact steps may vary slightly depending on your individual needs, here’s a general overview of what you can expect:
A Two-Appointment Process
Typically, the procedure involves two separate appointments, allowing time for the custom fabrication of your inlay or onlay.
- First Appointment: Preparation and Impressions
- During this initial visit, your dentist will conduct a thorough examination, including X-rays, to assess the extent of the damage and determine if an inlay or onlay is the right solution for you.
- The tooth will then be prepared by carefully removing any decayed or damaged areas, creating a clean and stable foundation for the restoration.
- Impressions of your teeth will be taken to create a precise model for the fabrication of your custom inlay or onlay.
- A temporary restoration may be placed to protect the tooth while your permanent inlay or onlay is being made.
- Second Appointment: Placement and Bonding
- At your second appointment, the dentist will carefully check the fit and appearance of the custom-made inlay or onlay.
- Once the fit is confirmed, the restoration will be securely bonded to your tooth using a strong dental adhesive.
- Final adjustments will be made to ensure proper bite alignment and comfort.
This two-step process ensures that your inlay or onlay fits perfectly and integrates seamlessly with your natural tooth structure, providing a durable and aesthetically pleasing restoration.
