Inlays and Onlays

When a cavity is too big for a simple filling, an inlay or onlay is employed.

Inlays and Onlays

An inlay is a single sold piece used to fill a cavity that is too large for simple filling.An onlay is larger than an inlay but less than a dental crown. It’s also a single solid piece but covers the full cusp of the tooth (not just the area between). Inlays and onlays are most typically required at the Advanced Dental Group of Hoboken in New Jersey when there is tooth decay or a fracture of the tooth.


  • Dental inlays and onlays provide additional strength and support for your affected tooth, allowing your tooth to withstand more chewing pressure.

  • Dental inlays and onlays can last longer than fillings with proper care.

  • With dental inlays and onlays less enamel is removed and more of your natural tooth is preserved.

  • Dental inlays and onlays are designed to blend with your natural tooth color/shade.

  • Dental inlays and onlays can often be completed in just one appointment.

  • Dental inlays and onlays can be used to restore a failed dental filling.

Can I get a filling instead of an inlay?

They both involve removing the existing cavity with a drill and filling that empty space, but how that space is filled is where they primarily differ.

What is inlay or onlay restoration?

An onlay or inlay is used when a cavity is too large for a regular filling. Both onlays and inlays are pre-formed in a laboratory before being bonded to the decayed or damaged tooth. They are a more conservative approach than a dental crown since they do not involve the removal of healthy tooth structure.
