Tooth Fillings & Restorations
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 esthetically 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 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 Fillings are used in place of Amalgam or silver fillings to restore your teeth when cavities or decay have been found. Another treatment option is a Resin Onlay. 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 contain fluoride this 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 or composite resin fillings). This process is usually completed in one visit. When Resin Onlays are the treatment of choice, this process will take two visits to complete.
Composite Resin Fillings
A composite filling is a tooth-colored plastic mixture filled with glass (silicon dioxide). It is done directly and in one visit. Composites are not only used to restore decayed areas, but are also used for cosmetic improvements of the smile by changing the color of the teeth ot reshaping disfigured teeth. The main advantage of composite resin is its appearance. It matches the color of the natural tooth and it can be bonded to the exitsing tooth. Composite materials and techniques have improved over the years and today composite resin fillings are the preferred choice in the majority of cases.
Your First Appointment:
- The old filling is removed along with any additional decay.
- 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 is carefully placed into the model of your teeth. It is then designed to look natural.
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 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!
