Fillings are the most common type of 'restorative treatment' in dentistry. Restorative treatment is generally needed because decay has caused a cavity to form in a tooth. Fillings are in many cases the first treatment option for decayed teeth, provided that the decay is in its early stages and has not progressed too far. It is the least expensive type of treatment. Filling a tooth literally means placing material into the tooth to replace the decayed tissue.

There are two types of filling available: amalgam and composite. Amalgam fillings are made of mercury, silver, copper and tin. Composite (also known as 'white' or 'tooth-coloured') fillings are typically made of glass particles, resin and a setting ingredient.
