There are several different types of materials used for white dental fillings that enable us to restore teeth. However, at The Perfect Smile, we like to use the new age composites and porcelains that have natural-looking aesthetics and incredible durability. We commonly use materials that give the appearance of natural teeth but also are hard wearing.
There are several types of fillings which are done in a single visit directly in you mouth, called Direct Fillings. These are :
- Amalgam Fillings:
These are the dark silver fillings commonly seen in the back teeth. They are quick and easy to do and are commonly carried out on the NHS.
Amalgam fillings have gained popularity since they are strong, durable and inexpensive. They consist of an amalgamation of Mercury liquid and an alloy powder that is then packed into a prepared cavity.
These are the traditional tooth coloured fillings. Composites made up of a very hard plastic and glass substance. The techniques used are more demanding than those needed for amalgam fillings. It involves shaping a soft putty-like material and then setting it hard with a bright blue light.
However, unlike amalgam fillings composite fillings are bonded to the tooth structure making them more secure. They also come in different densities and differing filler particle sizes which are used according to the type of restoration required for any individual case.
- Glass Ionomer Fillings:
These materials contain tiny glass particles combined with acrylic powder and set hard via chemical bonding.
They are popular in children’s dentistry since they only last approximately 5 years but they release fluoride thus help to prevent tooth decay.
- Compomer Fillings:
These are combined Glass Ionomer Cements with Composite resins. They incorporate the best of both strength and release of fluoride. Although they have slightly reduced aesthetics when compared to Composites.
There also fillings such as Enhanced Composite Fillings, which are reinforced composites that have superior properties such as those of porcelain, so they wear less and are stronger. They are often made in a process similar to ceramics and the treatment requires two visits and as such are called Indirect Fillings.
If you feel that you have had fillings in your mouth for a while or are aware of any symptoms please book in for a comprehensive Health Assessment. This is a detailed oral hygienic examination of your mouth to check for any infections and to determine the structural integrity of each and every tooth.
