Replacement of amalgam fillings
We are a practice that provides metal-free dentistry and mercury-free fillings. 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 and composite resin tooth colored restorations create fillings that are not only beautiful (or unnoticeable) but also add strength to weakened teeth. These restorations are esthetically pleasing and very strong.
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. Usually it is the tooth structure that will crack or break off, ultimately leading to a larger filling, crown and even root canal treatment.
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. Enamel and dentin bonding procedures allow for a more conservative tooth reduction compared to silver fillings. 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.
The result is a beautiful smile!
Replacing Silver fillings with a Tooth Colored Restoration
Depending on the size of your silver fillings, you can have them replaced with tooth colored restorations that are direct or indirect. Tooth-coloured (white) fillings (direct restoration) are placed in one appointment, but for those fillings that are larger, an indirect restoration is recommended (inlay or onlay). The indirect fillings are made of gold, porcelain or a processed composite resin. This process requires two appointments.
Your First Appointment:
- The old filling is removed along with any decay.
- An impression is made of your teeth and sent to the lab for fabrication.
- A temporary is placed on the tooth.
At the Lab:
A restoration is carefully placed into the model of your teeth. It is then designed to look natural.
Your Second Appointment:
- The temporary is removed.
- A conditioning gel is placed on your tooth to prepare it for the new restoration.
- Bonding cement is placed on the tooth and a high intensity light bonds the restoration to the tooth.
- The tooth and restoration is then polished.
Your teeth are restored to a natural look and feel, they are stronger and the tooth is protected!
