Most of us suffer from some or the other dental problem in our lifetime. Majority of these problems are attributed to tooth decay. Tooth decay or cavities occur when bacteria living in the mouth produce a strong acid that slowly deteriorates the health of the teeth. If left untreated such decays will lead to infection, causing extreme pain and eventually tooth loss. To prevent this, dental fillings are done. 

What is a Dental Filling?
A dental filling is one of the most commonly used methods that can restore the normal functioning and shape of the tooth, which may have been damaged due to tooth decay. These fillings close off the spaces where bacteria can set in and cause further decay. This protects the surrounding tissues too as food and bacteria accumulated in cavities can harm gums too. 

Procedure of Dental Filling: 
Before a filling session, the dentist will carry out proper assessmnt of your teeth. Dental X-rays may be used to ascertain the extent of the damage. This can be followed by a procedure with which the dentist will clean out the affected area of the tooth. After the decay has been cleaned out, the cavity will be filled with desired filling material. 

Types of Dental Fillings: 
There are various kinds of dental fillings. Let us find out a little bit about each kind. 

1. Gold filling: These are made in a laboratory before they are cemented in place. These fillings are known to last over two decades thanks to the fact that they are tolerated exceptionally well by the gum tissue. This is also an expensive option, which will require multiple visits to the dental clinic. 
2. Amalgam filling: These are also known as silver fillings and are usually an alloy containing tin, silver, and other metals, which bond well with the teeth. Many Dentists today are advising against the use of these fillings as it has been proved that mercury content in these fillings can harm the body.
3. Composite resin filling: These kinds of fillings are matched to the colour of your teeth for a natural appearance. These are the most commonly uses fillings today as they fulfill most of the criteria we would desire from a dental filling. 
4. Porcelain filling: These are known as inlays or onlays. These fillings are used in restorations where a large part of the tooth structure has been lost. If you wish to discuss about any specific problem, you can consult a dentist.
