What Is a Dental Onlay?

According to the CDC, more than 90% of adults (20 years or older) have had at least one cavity. Most people think that once you get a cavity, your only options are a filling or a crown. But there is another choice that many do not know about—dental onlays.

Not every damaged tooth needs a full crown. In some cases, choosing a crown might remove more healthy teeth than necessary. A dental onlay offers a straightforward and minimally invasive solution that preserves more of your natural tooth structure.

In this guide, you will learn what a dental onlay is, how the procedure works, why it might be right for you, and how it compares to fillings and crowns.

What Is a Tooth Onlay?

A dental onlay is a custom-fabricated piece that covers the damaged tooth. It is created in a lab and then attached to your tooth. It covers one or more of the raised parts on the top of your tooth, called cusps. You can think of it as a puzzle piece designed to fit your tooth perfectly.

tooth onlay provides an excellent solution when your tooth is more damaged than a filling can cover, but does not need a complete restoration or crown. It helps keep more of your natural tooth while still making it strong and functional again.

Step-by-Step Guide About What Happens During Cavity Filling

If you are going for the dental filling for the first time, grasping the process can make you feel more comfortable. Here is the complete detail of the simple process of a dental filling.

1. Examination and Analysis

Your dentist will examine and analyze your teeth thoroughly using different technologies, such as X-rays or imaging, to diagnose the exact problem. 

2. Numbing the Area

Your dentist will inject you with local anesthesia near the decayed teeth. It feels like a prick and then removes all the painful sensations. 

3. Removing the decay

Once your mouth is numbed, the dentist will eliminate the decayed section of the tooth and smooth it in preparation for the filling. This process is carried out with either a drill or a laser. 

4. Cleaning the Cavity

After removing the decayed part, your dentist will prepare it for the filling. They will sterilize, clean, and make this part germ-free. 

5. Filling the Teeth

Once your dentist has cleaned the teeth and prepared them for the filling, they will fill the cavity with the required material. After placing the filling, your dentist may use UV light to harden it, if needed.

6. Polishing

Now, your dentist will shape the filling to match the contours of your tooth. Then they polish it to give a natural and shiny look.

How Does the Dental Onlay Procedure Work?

How Does the Dental Onlay Procedure Work?

Lab Work
Your dental impression is forwarded to a dental lab. Your onlay for teeth is custom-crafted, usually from porcelain, resin, or gold.

Second Visit
During the second visit, the temporary onlay is removed. Your dentist cleans the tooth and checks the fit of the new onlay. It is then cemented in place and polished to give it a natural appearance. This method offers a snug fit, lasting results, with minimal discomfort.
