Fillings are inserted when there is a cavity in the structure of your tooth, whether caused by decay, bruxism (the grinding of teeth) or damage. Some fillings can last up to 15 years if looked after properly while also offering the added bonus that they are a less invasive alternative to crowns.

Different cavities are filled with different types of dental material. Amalgam fillings are made of a combination of metals, including silver, tin, copper and mercury. Though durable and able to withstand grinding and pressure, they are not as aesthetically pleasing and can be seen in the tooth. However, tooth-coloured fillings to match the colour of your teeth are also available. While commonly used in teeth that are visible, tooth-coloured fillings are not suitable for the back teeth where grinding may occur.
