Dental Onlays and Inlays

When someone has a damaged tooth, they may start thinking about crowns or fillings. However, inlays or onlays for people with a common level of tooth decay last longer than fillings and provide more structural tooth support. Inlays and onlays also require less tooth reshaping and reconstruction than crowns.


Dr. John Khoury and his knowledgeable staff help many people each year decide if dental onlays or inlays are the right restorations for them. The team at John Khoury Dental gives patients reliable, long-lasting restorations for optimal oral health. 

What Are Inlays and Onlays?

Dental onlays and inlays are similar and made of the same materials. However, they cover different areas of teeth.

·       Inlays: Similar to a filling, inlays go in the center of teeth.

·       Onlays: Onlays are large dental restorations that go over the cusps of teeth.

Dr. Khoury’s Onlay Procedure

If Dr. Khoury decides a patient needs an onlay, he will take impressions and x-rays of the tooth. A licensed technician constructs the onlay, using the impressions and x-rays to form it to exact specifications.


Dr. Khoury prepares the tooth by ridding it of any bacteria or decay. He then cements the onlay in place and polishes it to create a smooth surface.

Do I Need a Dental Onlay?

Teeth with minor decay require fillings. Teeth with severe decay require crowns to restore large surface area and strength to the teeth. Onlays are for teeth with a medium level of decay that would be weaker with a filling.


Onlays can strengthen teeth up to 75 percent and last as long as 30 years.
