GIC OR Glass Ionomer Cement is a commonly used material for fillings and it bears resemblance to the colour of the tooth hence is pleasing to the eye. It also releases fluoride and though you may not be aware of this but this is a good thing. Fluoride acts by remineralizing the organic crystals present in the tooth which helps to fight teeth decay thus preserving the life of the tooth.
These are highly aesthetic tooth coloured fillings that are recommended for anterior and posterior teeth. They require less trimming of the tooth and has high strength that can withstand chewing forces.
The decayed area of tooth is first removed during the procedure. A mould of the tooth is taken and send to the dental lab. They create a restoration from porcelain, gold or composite resin.
