Composite resins are used to make tooth-colored fillings. They are made from glass or quartz mixed with plastic resin. In New Orleans, Dr. Duane Delaune is a cosmetic dentist who only uses tooth-colored composite fillings.
How White Fillings and Amalgam Fillings Compare
White Fillings
- They bond to the tooth and make the tooth stronger.
- They require less removal of the tooth structure.
- Your teeth are less sensitive to hot and cold foods than they are with amalgam fillings.
- They don’t contain mercury, which is important to people who are concerned about the mercury in amalgam fillings.
- They look natural, so people can’t tell that you have fillings in your teeth.
- More time and skill are required to place them, so they cost more than amalgam fillings.
Amalgam Fillings
- More of the tooth structure must be removed to accommodate the filling.
- They are less expensive and easier to place than composite fillings.
- The filling is stronger than composite, but it weakens the tooth.
- Their color makes them more noticeable and less natural looking.
The photograph of the amalgam fillings on left shows that in some places, there is a gap between the filling and the tooth. Composite fillings bond to the teeth, and leave no gap. This bond makes the tooth stronger.
