TYPES OF DENTAL FILLINGS
| ¨
| Gold Fillings
| a
| This natural-looking dental material when placed on the affected tooth acts as a source of fluoride, which helps in remineralization. In addition, durability is a big disappointment as this filling need to be replaced after every 3 to 5 years.
|
| ¨
| Amalgam
| b
| Constructed from porcelain material, these tooth-colored fillings are sturdy and long-lasting. Their natural appearance makes them impossible to differentiate from natural teeth. They are expensive.
|
| ¨
| Composite
| c
| This material is very strong, and hence, can successfully withstand wear and tear for quite long. The filling does not wear away for at least 15 years.
|
| ¨
| Ceramic Fillings
| d
| Known as white fillings, they essentially consist of synthetic resin combined with plastic and glass particles. As the tooth-colored material cannot be detected, it is a sought-after filling for frontal teeth. This material does not last for more than 5 years.
|
| ¨
| Glass Ionomers
| e
| These fillings are a combination of multiple metals including mercury, silver, copper, and tin. In most cases, well-placed fillings last for about 12-13 years. Some dentists are of the opinion that this filling when fitted correctly, and complemented with proper oral care, may not require replacement for even up to 50 years!
