Composite Fillings, also knows as Tooth Colored Fillings are comprised of a resin which is a material designed for filling aesthetic dental restorations. This resin is designed in such a way that its color resembles your natural tooth. The main uses of composite resin are for filling dental cavities and also for dental bonding the front teeth.
The material that makes up Composite Fillings is comprised of quartz filler or glass combined with a resin medium. This mixture produces a filling whose color is that of natural teeth. This composite resin is a very effective substitute to the traditional amalgam dental fillings. However, there is no need to worry, even though the mixture contains glass and plastic, there is absolutely no metal in it. Perhaps the best thing about it is that it can be shaped to look like an ordinary tooth and people will not notice that your teeth have been filled.
How is a Composite Filling placed?
The composite material comes in a soft, moldable format allowing the dentist to shape the composite in such a way by layering the material to perfectly fit to be filled. A special light is then used to harden each of the layers after placement. This is repeated for each layer. After the completion of this process, the dentist will shape the composite in such a way that it fits the tooth that is. Finally, the composite will be polished so that staining and early wear do not occur.
What are the advantages of Composites?
The main advantage of composite is the aesthetics quality and capability. Dentists have the ability to shape the teeth and give them a color that will look the same as that of your natural teeth. Also, the composite is bonded to the tooth, so will support the remaining tooth structures. This helps in avoiding breakage of the teeth. It also helps in insulating the tooth from extreme temperatures.
What are the disadvantages?
Postoperative sensitivity is a short term side effects composite placement. Another disadvantage is that the shade of the composite can alter over time with staining from consuming consuming some beverages such as coffee, tea or other staining foods. Yet another disadvantage of composite fillings is that sometimes larger composite fillings can wear out faster than silver fillings, simply because there is more composite than tooth structure.

Choosing Composite (Tooth-Colored Fillings) over Amalgam
Many people are opting for composite fillings over silver amalgams. This is because silver amalgam fillings contain mercury and dentists are increasingly getting concerned over their safety. Since mercury is a toxic substance, dentists are researching as to whether mercury that has been used in silver amalgams can be toxic as it lives in the mouth region.
Many dentists hold the belief that tooth-colored fillings are a safe alternative to the silver amalgams. The material in composites is composed of a durable composite resin. The good thing about this material is that it is a moldable plastic material which bonds directly to the tooth. Also, this material is less conspicuous from the rest of the teeth as compared to silver amalgam.
Not only can the material color be altered to resemble the color of your natural teeth, it can also be altered so that it has the exact texture of the rest of your teeth. Many children also find silver amalgam to be rather embarrassing and so they opt for composite filling.
The advantages are numerous, such as:
- Almost invisible
- Free of toxic mercury
- Bonds to the teeth
