Mercury Free Fillings
EAST MADISON DENTAL | Tenafly NJ
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 lets cavities get started once again. With age, the metal of a silver filling expands, contracts, and can split.
Silver fillings contain 50% 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. Resin 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 used in tooth-colored restorations contains fluoride, it can help prevent decay. The resin wears like natural teeth and does not require placement at 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 (onlays). This process usually requires two appointments. However, with the new technology that is available in our office , we are now able to do the procedure in a single visit using the CEREC machine. Making it convenient and saving you precious time.
- The old filling is removed along with any additional decay.
- An optical imaging is made of your teeth and a model is projected in the computer. Using CEREC’s CAD-CAM technology, your final restoration is designed to re-create a replica of your natural tooth.
- Color shade will be decided to match your natural tooth and the material of choice is milled
- A temporary onlay is placed on the tooth.
- A resin is carefully placed into the model of your teeth. It is then designed to look natural.
- The temporary onlay is removed.
- A conditioning gel is placed on your tooth to prepare it for the new onlay.
- Bonding agent is then applied on the tooth and resin cement is placed in the restoration. A high intensity light bonds the restoration 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!
