Composite fillings, also known as white fillings, are more than just aesthetically better matched to the tooth, they have the distinct advantages over metal fillings as they are environmentally non toxic, as no mercury is used. Composite Fillings are bonded directly to the surface of the tooth thus protecting the tooth from fracturing as they do not require the removal of healthy tooth structure, as with mercury fillings.

Overview
Composite Fillings, aslo called as White Fillings, bond directly to the surface of the tooth and protect the tooth from fracturing as they do not require the removal of healthy tooth structure as mercury fillings do.In other words, a dental filling is a dental restorative material used to restore the function, integrity and shape of missing tooth structure. The structural loss typically results from decay or external trauma. It is also lost intentionally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material.

Procedure
Tooth preparation is usually required before placing a dental restoration. This process involves cutting the tooth usually with a dental drill to make space for the planned restoration, remove any dental decay and structurally unsound tooth. If permanent restoration cannot be carried out after tooth preparation, temporary restoration is done. Composite Dental composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives. Synthetic resins evolved as restorative materials since they were insoluble, aesthetic, and insensitive to dehydration and were inexpensive
