A filling is a treatment for tooth, damaged by decay, that restores back to its normal function and shape while preventing further decay.

It’s also the one of the most common procedures that takes place in the dental practice.

Your dentist will use a small mirror to examine the surfaces of each tooth, and anything that looks abnormal such as discoloration, is sensitive to temperature changes or defective, will be closely checked and X-rayed. The treatment will depend on the extent of damage and the type of filling you agree on.

There are different types of Fillings:

Amalgam Fillings was once one of the most common materials used to fill cavities. Also known as “silver fillings,” amalgam fillings are silver in appearance, is a mixture of mercury, silver, tin and copper. A necessary component, mercury binds the amalgam together so it moulds into the cavity. They are more versatile than the newer materials, because they can be used for other dental situations and hold up better over time, especially in teeth that undergo wear and tear from pressure and chewing. And it is less costly than other dental materials available.

Composite Fillings have a more natural appearance than other options. The composite material can be customized to match the shade of your tooth, so they’re almost unnoticeable to anyone who glances at your mouth as they can be matched closely to the colour of your teeth and bonds seamlessly to your own tooth. They look natural, so they’re great if your filling will be visible when you smile.

Glass Ionomer Fillings are made with a glass filler. Like composite resin fillings, glass ionomer fillings are tooth-coloured and can be shaded to blend in with a person’s teeth. This means they’ll be less obtrusive than an amalgam filling. They also release fluoride, which lessens the chance of a new cavity forming. But they’re also less durable than amalgam fillings and will not last as many years. Also, they may not be appropriate for large cavities.

Root Canal Treatment – is a dental procedure to treat infection at the centre of a tooth. Root canal treatment (also called endodontics) is needed when the blood or nerve supply of the tooth (known as the pulp) is infected through decay or injury. You may not feel any pain in the early stages of the infection. In some cases, your tooth could darken in colour, which may mean that the nerve of the tooth has died (or is dying). This would need root canal treatment.


Fillings are used to repair a cavity in your tooth caused by decay. Your dentist will offer you the type of filling they consider clinically necessary.

The most common type of filling is dental amalgam, made from a mixture of different metals. Dental amalgam fillings are often used on your back teeth as they’re hard-wearing.

If you need a filling for one of your front teeth, your dentist may suggest a tooth-coloured (white) filling.

What Types of Filling Materials Are Available?

Today, several dental filling materials are available. Teeth can be filled with gold; porcelain; silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper); or tooth-colored, plastic, and materials called composite resin fillings. There is also a material that contains glass particles and is known as glass ionomer. This material is used in ways similar to the use of composite resin fillings.
