Advances in Bonding Technology
When repairing cracked or chipped teeth, silver fillings have always been the most reliable options. This is true even though major weaknesses can cause silver fillings to crack easily. Thanks to advances in dental technology, we now have materials far superior to common silver fillings. These advancements have also given your dentist the ability to create a superior bond between natural teeth and fillings as well as allowing for simple repair of old, cracked fillings.
Weaknesses of Silver Fillings
Some of the specific weaknesses found in silver fillings are:
Silver fillings are expected to crack eventually. The constant expanding and contracting of the silver in your filling happens because of temperature changes.
Silver fillings can likely wear down around the edges over time. This wearing down can also add to the likeliness of the silver filling cracking.
Once the silver filling does crack, it leads to more problems. The tooth is exposed and makes it possible for additional infection, tooth decay and cavities.
Up to 50% of a silver filling can be made up of mercury. Once a silver filling cracks, mercury can leak from the filling and stain the teeth and gums in the area of the silver filling.
Advantages of Composite Fillings
Composite fillings have developed through advancements in dental technology. They have become much stronger.
Using a composite filling allows your dentist to match the shade of your natural teeth with great precision. As a result, composite fillings have a superior aesthetic appeal.
This is a great option for replacing silver fillings that were placed years ago before they have a chance to crack and leak.
