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 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. Resin ﬁllings are bonded to the teeth creating a tight, superior ﬁt to the natural tooth. Such restorations can be used in instances where some of the tooth structure has been lost. The tooth remains intact and stronger.
Since the resin used in tooth-colored restorations can 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!
