Fillings are done to remove decay, and replace the affected tooth structure. It is called a filling because the new material fills hole that the decay left. Now a days most teeth are treated with bonded tooth coloured composite resin fillings. Caught early enough, cavities can be treated easily and painlessly. If not treated decay can lead to tooth pain and/or infection, and the tooth would need root canal treatment or extraction.
ADVANTAGES OF WHITE FILLINGS:
- Since they bond to the tooth, composite fillings restore most of the original strength of the tooth. Silver weakens the teeth, making them more susceptible to breaking. Since broken teeth are very expensive to restore, composites can save a lot of expense over the long run.
- Composite 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.

ADVANTAGES OF SILVER AMALGAM FILLINGS:
- They are generally less expensive. Composite fillings, if they are done correctly, take about 60% longer, require special expertise and expensive materials, and are more difficult to place, and so they cost considerably more than silver. Dental insurance companies will generally not pick up this extra cost. Click here for extra information about the costs of white fillings.
- General dentists can place amalgam without extra training. Composite requires the use of special bonding technology that many dentists are uncomfortable with.
- The proper placement of a white filling requires that the site for the filling be kept totally isolated from saliva while it is being placed. In the very back of the mouth, on some patients, it is difficult to keep the tooth isolated for the duration of the procedure. This can also be uncomfortable for some patients. A silver amalgam filling does not require this strict isolation of the tooth.
- The filling by itself is a stronger material, although it weakens the tooth.
- Silver fillings have a longer history of use than mercury-free fillings, thus some feel that they are more tried and tested.
One caution-the composite fillings can be seriously weakened by excessive alcohol consumption. If you have a habit of drinking beverages with high alcohol content (whiskey, etc.) on a daily basis, you may find the composite fillings deteriorating prematurely.
