Silver weakens the teeth, making them more susceptible to breaking. Since broken teeth can be more expensive to restore, composites can save a lot of expense over the long run.
Here are some advantages of white fillings:
- Cosmetic fillings restore the natural appearance of the tooth.
- Teeth restored with white fillings are less sensitive to hot and cold than teeth restored with amalgam, if correct techniques are used.
- Composites are mercury-free. Mercury in the fillings is viewed by some as being toxic.
- Composites 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.
