Tooth Colored Fillings
A dental filling (a type of dental restoration) is used to restore the function, integrity and shape of missing or decayed teeth. The loss in tooth structure is typically a result of decay or other trauma.
Dental composites are also called white fillings. Some people still have silver/mercury fillings in their mouths from years past. However, these fillings don't look great and they actually weaken the tooth by the nature of their design.
On the other hand, dental composites create fillings that are unnoticeable and also add strength to teeth. Thanks to new bonding technologies, these fillings are very durable without sacrificing the appearance of your tooth.
Disadvantages of Silver Fillings
Because metal/silver fillings are not bonded to the existing tooth, they require larger preparations and undercuts to hold the filling in place. Over time, the metal expands and contracts, which can cause the tooth to split or crack.
Also, the edges of a silver filling can wear down, resulting in your tooth no longer being protected. When that happens, it creates an environment where cavities can form once again.
Last but not least, silver fillings can corrode, leak, and cause stains on your teeth and gums.
The good news is that silver fillings can safely be replaced with tooth-colored restorations and you'll never have to worry about any of these issues again.
Advantages of Tooth-Colored Restorations
Tooth-colored restorations are better in every way.
Composites are bonded to the tooth, which creates a very tight fit to the natural tooth and leaves no gap at all. Because the restorations are bonded to the tooth, the preparations can be kept smaller, which saves more of your natural tooth structure.
Such restorations can even be used in instances where much of the tooth structure has been lost. The tooth remains intact and stronger with the addition of tooth-colored restorations.
