Silver-fillings
(Amalgams)
Advantages:
- Durability
- lasts at least 10 to 15 years and usually outlasts
composite fillings
- Strength
- can withstand chewing forces
- Expense
- is less expensive than composite fillings
Disadvantages:
-
Poor aesthetics - fillings don't match the color of
your natural teeth
- Destruction
of more tooth structure - healthy parts of the tooth
must often be removed to make a space large enough
to hold the amalgam filling
- Discoloration
- amalgam fillings can create a grayish hue to the
surrounding tooth structure
- Cracks
and fractures - although all teeth expand and contract
in the presence of hot and cold liquids, which ultimately
can cause the tooth to crack or fracture, amalgam
material - in comparison with other filling materials-may
experience a wider degree of expansion and contraction
and lead to a higher incidence of cracks and fractures
- Allergic
reactions - a small percentage of people, approximately
1%, are allergic to the mercury present in amalgam
restorations
