New precautionary measures in place to minimise the risk of exposure to coronavirus (COVID-19)
Do you have sensitivity? Can you feel a hole? If so then you might need a filling so a checkup is always a good place to start. Fillings can be white or grey in colour and are typically used if you have a hole or cavity in your tooth or teeth. The decay is cleared and the hole sealed to prevent the cavity getting bigger.
Technological advances have rendered cosmetic white fillings as strong and reliable as the traditional mercury amalgam fillings. White fillings are available in a variety of shades in order to ensure that the colour of the filling matches the shade of the tooth. This provides a more natural appearance. Composite can also be used to build up and re-contour teeth, as well as change their shape and close selective spacing, enhancing the overall form and aesthetics of the mouth.
Amalgam fillings are silver coloured. They are made by combining mercury and a silver alloy. Amalgam is long lasting, hard wearing and economical to use. This kind of filling is normally used on the back ‘chewing’ teeth.
