As a trusted dentist in Charlotte, NC, we are committed to providing our patients with the best dental care options. One of the common decisions patients face is whether to opt for Onlays vs Crowns for tooth restoration. Here, we’ll explore the differences between these two treatments, highlighting why a conservative onlay might be the better choice for preserving your tooth’s health and structure.
Understanding Onlays vs Crowns
What is an Onlay?

An onlay is a type of dental restoration used to repair a tooth that has been damaged by decay or trauma. Onlays are similar to fillings but are more extensive, covering one or more cusps (the pointed parts of a tooth). They are often referred to as “partial crowns” because they restore the damaged portion of the tooth without covering the entire tooth structure.
What is a Crown?
A crown, also known as a cap, is a dental restoration that completely encases a damaged or decayed tooth. Crowns are used when a tooth is significantly weakened and requires full coverage to restore its shape, size, strength, and appearance.
Benefits of Choosing Onlays
1. Conservative Approach
Onlays are a more conservative treatment option compared to crowns. They require less removal of the natural tooth structure, which helps preserve the integrity of the tooth. By conserving more of your natural tooth, onlays maintain its strength and function more effectively.
2. Better Fit and Function
Thanks to our in-house milling technology, we can create precise and custom-fitted onlays that offer a superior fit. This predictability enhances the functionality and longevity of the restoration, ensuring your tooth remains strong and healthy.
3. Aesthetic Advantages
Onlays are typically made from tooth-colored materials such as porcelain or composite resin, which blend seamlessly with your natural teeth. This results in a more aesthetically pleasing appearance compared to traditional metal crowns.
When to Choose a Crown
While onlays offer numerous benefits, there are situations where a crown might be the more appropriate choice:
- Severe Damage: If a tooth is extensively damaged or weakened, a crown may provide the necessary strength and protection.
- Root Canal Treatment: Teeth that have undergone root canal therapy often require crowns to restore and protect them.
- Large Fillings: A crown can offer the stability needed when a tooth has a large filling that compromises its structure.
