Replacing Silver Fillings With A Tooth-Colored Restoration

We are a mercury-free practice. However, many people still have silver/mercury fillings in their mouths from years past. These fillings are not particularly pleasing to the eye, and we know that by unavoidable design, silver/mercury fillings ultimately result in a weaker tooth structure. Porcelain inlays and tooth-colored restorations (onlays) create fillings that are not only beautiful (or unnoticeable), but also add strength to weakened teeth. These restorations are aesthetically pleasing and very strong thanks to new bonding technologies.

Disadvantages Of Silver Fillings

Silver fillings have many drawbacks. The edges of the silver filling can wear down, become weak or break. This results in the tooth not being protected and creates an environment where cavities get started once again. With age, the metal of a silver filling corrodes, expands, contracts, and can split the tooth.

Silver fillings contain 50 percent mercury.
They can corrode, leak, and cause stains on your teeth and gums.

Fortunately, silver fillings can safely be replaced with tooth-colored restorations.

Advantages of Tooth-Colored Restorations

There are many advantages to tooth-colored restorations. composite resin or porcelain inlays/onlays are bonded to the teeth creating a tight, superior fit to the natural tooth. Such restorations can be used in instances where much of the tooth structure has been lost. The tooth remains intact and stronger.

Since the resin cement used with tooth-colored restorations can contain fluoride this can help prevent decay. The tooth colored restoration wears like natural teeth and does not require placement below the gum line, which is healthier for your gums!

The result is a beautiful smile!

Replacing Silver Fillings With A Tooth-Colored Restoration

You can have your silver fillings replaced with tooth-colored restorations (inlay/onlays). This procedure can often be done in one sitting using computer assisted design and computer assisted milling (CADCAM) or in two appointments using chairside oral scanning (COS). Both of these technologies give excellent results. You will hear us refer to the CADCAM machine as CEREC, which simply translates to ceramic reconstruction in one visit.

When replacing very small old silver fillings or treating initial decay composite resin can be used to restore the missing tooth structure.

Your First Appointment

  • The old filling is removed and any additional decay and cracks that may be present.
  • An impression is made of your teeth. A model of your teeth is made and sent to the lab.
  • A temporary onlay is placed on the tooth.

At The Lab

A resin or porcelain is carefully placed into the model of your teeth. It is then designed to look like your natural tooth.

Your Second Appointment

  • The temporary onlay is removed.
  • A conditioning gel is placed on your tooth to prepare it for the new onlay.
  • Bonding cement is placed on the tooth and a high intensity light bonds the resin or porcelain to the tooth.
  • The tooth is then polished.

Your teeth are restored to a natural look and feel,
they are stronger and the tooth is protected!
