Fillings are common dental treatments and are a standard part of general dentistry. An injection is used to numb the area around the tooth which is to be filled: for those with a fear of needles, HDC has a gel that can be used as an alternative. The cavity is then drilled and cleaned to remove all of the decay and prepare the area for the filling. A thin layer of resin may be applied to the hole before the filling is packed in to protect nerves and blood vessels. Following this, the filling is moulded into the cavity and will begin to harden: some take a few minutes, some harden in seconds aided with a blue light.
Fillings used to be made from amalgam; an alloy made mostly of tin, silver, mercury and copper. However today, here at HDC we only use gold and glass ionomer which is a superior substitute.
