Composite materials are largely used for fillings, but standard amalgam fillings can also be applied at the patient’s request.
For the majority of cases, white fillings i.e. fillings adjusted to tooth colour are used, because the procedures involved in making white fillings allow for minimal grinding. This way, the greatest amount of healthy tooth mass is preserved, and these fillings do not contain any heavy metals like mercury (Hg) that are detrimental to one’s health. The appearance of white fillings is incomparably better than that of amalgam fillings, which turn black with time.
Since the principle of minimal grinding preserves much more of the tooth mass than the classical approach to fillings, white fillings extend tooth lifetime compared to black ones, and prosthetic treatments can be postponed for quite some time.
