The disadvantage is that it costs more than an amalgam silver filing. There are still patients that can’t afford to get composite filings. Some medical insurances cover the larger portion of the cost. The composite material is not as strong as amalgam, but the latest advancements provide so many types that it’s much easier to find one that is perfect for posterior teeth. Another thing that patients have to be aware of is that they might experience some post-treatment sensitivity, but it goes away very fast. Composites don’t last forever, and they can change color. The reason behind this is the consumption of drinks and foods that can stain. Also, smoking can cause the fillings to become darker.
Uses:
This is the most commonly used material for dental fillings. Caries is a very frequent disease, so once the dentist removes it, the cavity has to be filled with a material. In the past it was the amalgam, today it is usually composite. Different brands offer different types of composites. There are also composites that are preferably used for frontal teeth and are great for aesthetics, and ones used for posterior and can withhold a larger pressure. Another common use of this material is for cosmetic purposes. That means that patients can get a white, straighter smile. It is not indicated in all cases but can help with mild spacing, short teeth, mild forms of crooked teeth, chipped, broken and more.
