Professional Inlays & Onlays

Inlays and Onlays represent a sophisticated, conservative approach to restoring teeth that have too much damage for a standard dental filling but not enough to warrant a full crown. Often referred to as “partial crowns,” these custom-made restorations at Dr 7 Family Dentistry are crafted in a dental lab to fit the prepared tooth structure precisely, offering superior strength, durability, and a stronger protective seal than traditional large fillings.

What Are Dental Fillings?

Inlays and Onlays are indirect restorations, meaning they are created outside the mouth (in a specialized dental lab) and then precisely bonded into the prepared tooth by the dentist. This allows for exceptional accuracy and material strength.

  • Inlays: Fit specifically within the biting surfaces (cusps) of the tooth. They are used when decay or damage is confined to the center of the tooth.
  • Onlays: Also known as partial crowns, Onlays cover one or more cusps of the tooth. They are necessary when the damage is more extensive and the cusps need structural support to prevent fracture.

These restorations are typically made from durable materials like porcelain, ceramic, or high-strength composite, ensuring they are both highly aesthetic and built to last.

Benefits of Inlays & Onlays

Maximal Tooth Preservation

Unlike full crowns, Inlays and Onlays require significantly less removal of healthy tooth structure, promoting a more conservative and bio-friendly restoration.

Superior Strength and Longevity

Because they are fabricated in a lab under high heat and pressure, they are structurally superior to large, direct fillings and are engineered to withstand greater chewing forces without failing.

Perfect Fit and Marginal Seal

The indirect fabrication process ensures a precise margin, meaning the restoration fits perfectly with the tooth. This reduces the risk of recurrent decay and leakage, offering a stronger, more protective seal.

Highly Aesthetic Result

Crafted from porcelain or ceramic, Inlays and Onlays can be color-matched and polished to a lifelike luster that is indistinguishable from the surrounding natural tooth.

Our Inlays & Onlays Process

A precise, minimally invasive approach to rebuild damaged teeth with long-lasting strength.

Comprehensive Examination & Treatment Planning

We evaluate the tooth, determine the extent of damage, and decide whether an inlay or onlay is the best solution.

01

Tooth Preparation & Impression Taking

The decayed or damaged area is removed and the tooth is shaped, followed by taking a detailed impression for fabrication.

02

Inlays & Onlays

03

Temporary Restoration Placement

A temporary inlay or onlay is applied to protect the prepared tooth while the permanent restoration is being crafted.

04

Final Inlay/Onlay Bonding

The custom-made restoration is fitted, refined for comfort and bite accuracy, and permanently bonded to the tooth.

Who Needs Inlays & Onlays?

Inlays and Onlays are the best choice for teeth that meet the following criteria:

Large, Failing Fillings

Teeth that have extensive decay beneath large, compromised metal or composite fillings.

Minor Fractured Cusps

Teeth that have chipped or fractured one or two cusps but still retain enough healthy tooth structure that a full crown is not yet necessary.

Structural Integrity Concerns

Teeth that need restoration but require the superior strength of a laboratory-fabricated piece to prevent future breakage under chewing load.

Need for Conservative Care

Patients who value preserving as much of their natural tooth structure as possible.

Cost and Insurance Information

Inlays and onlays are custom restorations used to repair moderately damaged teeth while preserving more natural tooth structure. The cost of treatment depends on the size of the restoration, materials used, and individual clinical needs. Coverage for inlays and onlays varies by insurance plan.

Dr7 Family Dentistry accepts the Canadian Dental Care Plan (CDCP) for eligible patients. Coverage for inlays and onlays under CDCP depends on clinical need and program guidelines. Our team will review your coverage and explain any costs before treatment begins.

For patients without insurance or CDCP coverage, fees are discussed clearly in advance as part of your treatment plan.

Frequently Asked Questions

What is the main difference between an Onlay and a Crown?

An Onlay covers one or more cusps but leaves significant portions of the natural tooth intact. A Crown covers the entire tooth surface above the gum line (all four sides and the chewing surface).

Due to their superior fabrication process, Inlays and Onlays typically last longer than large fillings, often lasting 10 to 20 years with proper care and hygiene.

No. The procedure is painless as we use local anesthesia to numb the area during the preparation appointment. You will wear a temporary filling between visits, and the final bonding procedure is quick and comfortable.

They are most commonly made of tooth-colored materials like high-strength porcelain, ceramic, or gold (though gold is less common today). We typically use porcelain or ceramic for aesthetics.
