Composites/Resin Tooth Colored Fillings
A composite filling bonds to the tooth structure and restores most of the original strength of the tooth. Silver (Amalgam) weakens the teeth, making them more susceptible to breaking due to cracks from expansion of the silver. Since broken teeth are very expensive to restore, composites can save a lot of expense over the long run.
In the example it shows that composite fillings restore the natural appearance of the teeth verses the silver fillings.
Teeth restored with composite fillings are less sensitive to hot and cold than teeth restored with amalgam, if correct techniques are used. Composites are mercury-free and require less removal of tooth structure. Especially with new cavities, the size of the hole made for the filling can be dramatically smaller with composites.
