Mercury-Free Restorations

I made a choice to stop using "mercury-containing" fillings in 1993. Although these "silver" fillings were easy to use and relatively inexpensive, they had a nasty habit of breaking many of the teeth in which they were placed. Mercury is the silver liquid we see in thermometers. As it heats up, it expands. As it cools down, it contracts. This expanding and contracting also occurs in the fillings in your teeth as you eat hot and cold foods.

Eventually, all of this expanding and contracting causes cracks to develop in your teeth. When "silver fillings" break a tooth, the tooth usually requires a crown or Filtek® all-ceramic onlay for a repair. Most of the crowns or Filtek® onlay restorations I do at my cosmetic dentistry practice today are to repair teeth with old silver fillings.

Most of the tooth-colored restorations that are made in our cosmetic dentistry office are made by our computerized milling machine, the Filtek® 3. This little robot can actually replace just the broken part of your tooth without destroying any additional sound tooth structure. The technology is amazing!

We will first take a digital radiograph of your broken tooth. This helps us to determine whether a crown or a Filtek® restoration is the best way to repair your tooth. If a Filtek® all-ceramic restoration can be used it will take only one appointment to repair your tooth. A digital picture captures the broken portion of your tooth. The computer then designs a replacement part for your tooth and the milling machine will carve an exact replacement for the missing part of your tooth. This usually takes about 10 minutes. This precision tooth-colored ceramic repair is then bonded to your natural tooth and you are ready to go.

You can resume your normal chewing, brushing, and flossing activities immediately.

In our cosmetic dentistry office in New Jersey, we recognize the problems with these mercury-containing fillings, and try to help you avoid the problems of unexpected tooth breakage. At your cleaning and exam appointment, we use our computer imaging, and intraoral camera to help locate and evaluate the cracks in your teeth. If they look dangerous, we will recommend a crown or Filtek® restoration to protect your tooth. To learn more about mercury-free restorations, please contact Dr. Rockson today!


Making porcelain veneers, inlays, onlays and crowns used to be quite an involved process. In the past, your dentist had to take impressions of your teeth, and then send them off to a dental lab, where the restoration would be crafted. You would then have to return to the dentist's office to have your restoration installed.

Now, with revolutionary new Filtek® technology, Dr. Rockson can create inlays, onlays, crowns, and porcelain veneers at his South Orange, New jersey office, allowing your dental work to be done over the course of just one single office visit.

Dr. Rockson takes digital impressions of your teeth, which the Filtek® machine uses to design and then mill a restoration, custom made to suit your needs and to perfectly match the color of the rest of your teeth. If you are unhappy with the color of your teeth, we can first perform teeth whitening at our New Jersey cosmetic dentistry office, and then have the restoration fabricated to match the new shade of your teeth.
