Inlays & Onlays
What are Inlays & Onlays?
Inlays and onlays are custom-crafted, highly durable dental restorations—often referred to as partial crowns—used to repair moderate tooth decay, structural damage, or cracked cusps while preserving as much of your healthy, natural tooth structure as possible. An inlay fits securely within the indented chewing surface (cusps) of a tooth, while an onlay extends over one or more raised cusps to rebuild and strengthen a heavily compromised tooth.
At Cleopatra Dental, we specialize in conservative, artistic restorative care for patients across Yorba Linda and Riverside. Using state-of-the-art CEREC Prime Mill 3D CAD/CAM technology, our clinical directors—Dr. George Mirsal and Dr. Engy Halim—can design, craft, and permanently place beautiful, tooth-colored porcelain inlays and onlays in just a single appointment.
Whether you are replacing an old, unsightly metal filling or seeking to repair a fractured back molar without resorting to a full crown, our royal-level team delivers long-lasting, seamless results in a relaxing, fear-free setting.

Signs You May Need Inlays & Onlays
When a tooth suffers damage that is too extensive for a standard composite filling, but strong enough that a full-coverage crown is unnecessary, inlays and onlays provide the ideal, tissue-preserving solution. Recognizing early signs of structural weakness helps prevent sudden tooth fractures and deeper nerve damage.
- Pain or Sharp Discomfort When Chewing: Sharp, localized pain when biting down on hard foods, signaling a cracked cusp or deep cavity.
- Failing or Fractured Silver Amalgam Fillings: Large, aging metal fillings that have loosened, worn down, or developed dark cracks around the surrounding tooth enamel.
- Chipped, Cracked, or Worn-Down Tooth Cusps: Visible breakage or structural flattening on the chewing surfaces of your back molars and premolars.
- Persistent Food Trapping Between Teeth: Spaces or worn dental margins that constantly collect food particles and cause localized gum irritation.
- Lingering Tooth Sensitivity to Hot or Cold: Noticeable temperature sensitivity caused by weakened enamel or exposed dentin underneath an old restoration.
Who is a Candidate for Inlays & Onlays?
A comprehensive professional examination accompanied by low-radiation digital X-rays or high-definition 3D CBCT digital imaging is the only way to accurately evaluate your remaining healthy tooth structure and determine if a partial crown is the right restorative option for your smile. We recommend scheduling an initial consultation if you are displaying any of the following symptoms:
- Moderate tooth decay that requires more support than a standard tooth-colored filling can offer.
- Broken or cracked tooth cusps where the majority of the lower tooth structure remains intact and healthy.
- Aging, oversized metal fillings that are compromising the structural integrity of your natural tooth.
- A desire for conservative, tissue-saving treatments that avoid the extensive enamel trimming required for a full crown.
- A preference for fast, single-visit ceramic restorations powered by advanced digital CAD/CAM technology.
The Ceramic Inlays & Onlays Procedure at Cleopatra Dental
Step 1: Digital Diagnostics & Conservative Preparation — Using local anesthesia, Dr. George Mirsal or Dr. Engy Halim gently removes only the decayed or fractured tooth structure, preserving up to 70% more healthy natural enamel than a traditional full crown preparation.
Step 2: 3D Intraoral Optical Impression — Instead of messy putty trays, we capture a sub-millimeter 3D digital scan of the prepared cavity and opposing bite.
Step 3: Custom Ceramic Milling (CDT D2610–D2644) — Your inlay or onlay is precision-milled from high-strength lithium disilicate porcelain (IPS e.max) or zirconia shaded to blend invisibly with your natural tooth.
Step 4: Adhesive Resin Bonding & Occlusal Calibration — We bond the ceramic restoration to your tooth using dual-cure resin cement, seal all margins, and polish your bite to a smooth, natural finish.
