What kind of materials are used for filling the teeth?
Materials used for fillings include a composite resin (tooth-colored fillings or white fillings), gold, and porcelain, which are used in inlays. Dentists used to apply amalgam, which is an alloy of Mercury, Silver, Copper, Tin and sometimes Zinc, but we don't apply this material any longer.
How long lasting these fillings are?
These have the same color as your teeth and therefore, are used where a natural appearance is desired. They can also become stained from coffee, tea or tobacco, and do not last as long as other types of fillings; generally, from three to ten years
Does it hurt?
With nowadays used anaesthetic agents it is completely painless.
If the amalgam filling is large, is it possible to replace it with white filling?
It depends on the patient and the situation. If there is not enough healthy tooth tissue and a large filling must be done, than the edges of the tooth can break down, in this case an inlay is suggested. The dentist makes a cavity into which the dental technician will prepare the consolidated filling, then the dentist glues it into the tooth. This way the original shape of the tooth can be fully set back.
