When a tooth has moderate decay or damage, a traditional filling may not be strong enough, while a full crown may remove more healthy tooth structure than necessary. Dental inlays and onlays offer a precise, long-lasting solution that restores strength while preserving your natural tooth.
At Aventura Dentistry, our experienced dental team uses advanced materials and techniques to deliver custom inlays and onlays that look natural, fit comfortably, and support long-term oral health.
What Are Dental Inlays and Onlays?
Dental inlays and onlays are custom-made indirect restorations used to repair teeth affected by moderate decay, fractures, or wear. Unlike traditional fillings, these restorations are fabricated in a dental laboratory for an exact fit and then bonded securely to the tooth.
They are most commonly used on molars and premolars, where chewing pressure is highest and durability is essential.
Difference Between Inlays and Onlays
Understanding the difference helps determine the best treatment:
- Inlays restore damage within the grooves of the tooth, between the cusps
- Onlays extend over one or more cusps when damage is more extensive
Both options reinforce the tooth without covering it entirely, making them a more conservative alternative to crowns.
Benefits of Inlays and Onlays
Patients choose inlays and onlays because they offer:
- Superior strength compared to traditional fillings
- Precise, custom fit for long-term stability
- Natural appearance that blends with surrounding teeth
- Preservation of healthy tooth structure
- Improved resistance to chewing forces
- Reduced risk of future cracking or decay
These restorations are ideal for patients who value durability and conservative care.
How Long Do Inlays and Onlays Last?
With proper care, dental inlays and onlays can last 10–30 years.
Longevity depends on:
- Daily brushing and flossing habits
- Regular dental checkups
- Bite alignment and grinding habits
- Material selection
Patients who grind their teeth may benefit from a custom nightguard to protect restorations.
Onlays vs. Dental Crowns
While both restore damaged teeth, they serve different purposes:
- Onlays preserve more natural tooth structure and require minimal reshaping
- Crowns cover the entire tooth and are used when damage is extensive
At Aventura Dentistry, we recommend the least invasive option that still provides long-term strength and protection.
Inlays vs. Traditional Fillings
Inlays outperform fillings in larger restorations because they:
- Do not expand and contract like metal fillings
- Are bonded for enhanced tooth strength
- Handle higher chewing pressure
- Fit more precisely due to lab fabrication
Fillings may still be appropriate for small cavities, but inlays are preferred when durability and longevity matter.
