When a tooth experiences moderate to severe decay or structural damage, dentists often face a choice between a large composite filling and a full-coverage dental crown. Fortunately, there is an ideal conservative middle ground: porcelain inlays and onlays.
Often called “partial crowns,” inlays and onlays allow Dr. Bryanna Hubbard at BB Dental Care in Burbank to restore damaged molars while conserving as much healthy natural tooth enamel as possible.
Inlays vs. Onlays: How They Differ
Both inlays and onlays are indirect restorations, meaning they are custom-milled in a dental laboratory rather than molded directly inside your mouth:
- Inlays: Designed to fit inside the cusps (central indented grooves) of a back molar or premolar, similar to a filling but fabricated as a single solid porcelain piece for superior durability and tight margins.
- Onlays: More comprehensive than inlays, onlays cover one or more damaged cusps (outer pointed tips) of the tooth. An onlay reinforces weak tooth walls against heavy chewing pressure without requiring the entire outer surface of the tooth to be shaved down for a crown.
Clinical Advantages of Porcelain Inlays & Onlays
- Preserving Healthy Enamel: Minimally invasive dentistry prioritizes keeping your natural tooth walls intact. Inlays and onlays only replace the damaged section.
- Superior Structural Reinforcement: High-density dental porcelain bonded to tooth structure can restore up to 75% of a tooth’s original strength.
- Lifelike Shade & Translucency: Ceramic materials replicate the optical characteristics, shade variations, and light reflection of natural tooth enamel.
- Resistant to Wear and Expansion: Unlike metal fillings, porcelain does not expand or contract when you drink hot coffee or iced water, preventing micro-fractures.
The Treatment Journey
Restoring a tooth with an inlay or onlay typically takes two appointments:
- Gentle Preparation & 3D Scanning: Dr. Hubbard removes the damaged area and captures a digital 3D impression without uncomfortable tray putty. A comfortable temporary restoration protects your tooth in the interim.
- Permanent Bonding: Once your custom ceramic piece arrives from our dental lab, Dr. Hubbard checks the contact points and bite alignment before securely bonding it to your tooth with high-strength dental resin.
If you have a cracked tooth, a damaged filling, or old amalgam that needs repair, contact BB Dental Care in Burbank to explore whether a conservative inlay or onlay is right for you.
