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.
A dental restoration or dental filling is a dental restorative material used artificially to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from caries or external trauma. Dental restorations may be fabricated out of a variety of materials:
Dental composites are also called white fillings.
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 are optimally used in instances where little 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!
The result is a beautiful smile!
Disadvantages Of Silver Fillings
Silver fillings have many drawbacks, and we discontinued doing many years ago. 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.
