Dental Crowns (Zirconia)

What are Dental Crowns?

A dental crown is a restoration that covers a tooth that has become compromised. A tooth that has fractured, cracked or broken will benefit from a dental crown. We use zirconia dental crowns in our office, as they are the strongest restoration material available. Zirconia crowns can last for years and even decades with proper care and routine dental checkups.

Why are Dental Crowns needed?

Before a crown is placed, we’ll perform an exam to determine if it is needed. Crowns can be placed on adult teeth that have been compromised in some way. The most common reasons for needing a zirconia crown include:

• A tooth has broken, cracked, fractured or chipped
• A tooth has a large filling
• You’ve recently had a root canal
• A dental implant was placed and has healed

What kind of Dental Crowns do you Provide?

We offer a variety of dental crowns suitable to help our patients and their particular circumstances. Some of these include: 

  • Stainless Steel: The traditional type of crown used for children is stainless steel. It is a great option because it is flexible and holds up well in the mouth.


  • Hall Technique: With the traditional stainless steel crown we are able to place them traditionally (local anesthetic and preparation of the tooth with a bur) or with what is called the “hall technique”. The hall technique is a great option for those children who have a larger cavity that requires a crown but would not tolerate treatment with local anesthetic. Dr. Ong is able to place a stainless steel crown over the tooth and cement it in place with very little to no preparation (drilling, etc.) of the tooth. In this instance, the crown will generally starve the cavity/bacteria of oxygen and it will die and no longer continue to grow.


  • Zirconia (white) crowns: We also offer white crowns that are made from a zirconia material. These look most similar to an adult crown that you may be accustomed to. These crowns are a great option for those kiddos who are able to tolerate treatment well or for those who are having treatment done under general anesthesia. The placement of these is a bit more technique sensitive so cooperation is important. During placement of a white crown, local anesthetic is needed in all cases. While the white crowns may be more aesthetically pleasing, they are not always the best choice. Dr. Ong will discuss with you the options for your child and which option he would recommend. Of course, if you only want a white crown, let us know, and we’ll do everything we can to make it happen!


  •  Different from adult teeth/crowns, the crowns placed on primary teeth are done in one visit without having to take impressions and being sent to a lab. When there are multiple teeth needing crowns, the child may have to come for multiple visits in order to complete treatment in full but each tooth worked on will have the crown placed that day. While Dr. Ong always tries to be as conservative as possible and do traditional fillings whenever he can, sometimes a crown is the only option to save a tooth. Hopefully now after reading the information about them and the steps involved, it will help put your mind at ease!

What makes you a good candidate for Dental Crowns?

The dental crown procedure is done in under an hour in our office. It is done under local anesthetic, so no sedation is needed unless otherwise requested. Most patients who need a crown can benefit from the new restoration. The crown not only improves the look of your smile, but it helps in improving overall functioning of the teeth.

What happens during the Dental Crown procedure?

You will receive local anesthetic to numb the area that will be receiving the new zirconia crown. The tooth will then be filed down completely so that the crown can sit comfortably on top. Molds, or impressions, are taken of the area and sent to a lab where your new zirconia crown is made. We will take a match of your smile to ensure the new crown will blend well with the rest of your teeth. Once the new crown comes into our office, you’ll come in to have it placed and the bite smoothed. Your new zirconia crown will last for years without the need for replacement.
