A filling is something that most people will have undergone at some point in their lives. They are a form of treatment for tooth decay or to restore a damaged tooth. The most popular type of filling is the silver amalgam filling.
What is a Cosmetic Filling?
A filling is the name of a dental procedure in which a material such as silver amalgam or a composite (white) filling is used to treat a decayed tooth. This material is inserted into the tooth where it then prevents the further spread of decay or repairs any damage.
This treatment stops the decay from spreading into the root where it will cause a serious infection, e.g. an abscess. This also removes the need for a tooth extraction.
The silver amalgam filling is the traditional type of filling which is composed of various metals such as copper, tin and mercury. This combination helps to retain the normal function of the tooth.
The composite white filling is a synthetic combination of acrylic resin and glass which has a white colour thereby enabling it to match the colour of the tooth. This is also chosen for aesthetic reasons as many people prefer to have fillings which match the rest of their teeth rather than the distinctive silver filling.
Advantages of Cosmetic Fillings
The main advantage of silver amalgam fillings is their durability. These fillings can last for more than 10 years or more compared to other types of fillings. The downside to silver restorations, overtime, these restorations begin to expand causing unexpected fracturing or cracking of your teeth. In addition, there have been issues raised about the safety of silver amalgam due to the mercury content which has prompted many people to switch to composite fillings instead.
Composite white fillings have a natural color which is similar to the color of your natural teeth and so blends it well with them. White restorations do not expand overtime the way that silver restorations do. With the appropriate placement and maintenance of these restorations, they should be stable and remain strong for many years to come.
Plus there have been issues raised about the safety of silver amalgam fillings due to their mercury content which has prompted some people to switch to composite fillings instead.
How is it Performed?
For both the silver amalgam and composite white fillings the procedure involves the drilling of a small hole within the affected tooth which is then packed with the filling.
The only difference is that the dentist will give the composite filling a final polish to ensure that it has that clean, white look and fits in with the rest of your teeth.
