A dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from caries or external trauma. It is also lost intentionally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material.
What are the benefits of composite fillings as compared to traditional amalgam fillings?
Because they are white, composite fillings match your natural teeth collaring far better than metal based fillings which are silver. So, when you show your pearly whites, they will actually be white! Composite fillings produced less stress than amalgam fillings on your teeth. Because your composite fillings dentist will use a high-intensity light to queue on your composite fillings, the material used remains soft and pliable until the light is shined.
Dental composite fillings are more resistant to temperature changes than are amalgam fillings. Because amalgam fillings contract and expand with temperature differences, they are likely to make your teeth crack over time. Composite fillings actually insulate your real teeth and add extra structural support.
