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 onlays create restorations 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% 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 material used in tooth-colored fillings 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!
Porcelain 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.
The result is a beautiful smile!
Replacing Larger Silver Fillings With a Tooth-Colored Restoration
At times, larger silver fillings cause fractures in a tooth. Many times, bacteria and fluids travel through the fractures into the tooth and cause decay within the tooth. Depending on the amount of missing tooth structure, our doctors may recommend replacement of the filling with a tooth-colored onlay or inlay. This process requires only one visit.
- The old filling is removed along with any additional decay.
- An digital impression is made of your teeth.
- A CEREC onlay is fabricated.
- 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!
