When you get cavities on your teeth or fracture your tooth while chewing something, they can be restored.  If the examination shows it is restorable, you have the choice of two basic materials to restore your tooth to optimum health.

As the name suggests, this material has silver color.  It is used to restore teeth in the back of your mouth.  It stays in your teeth by pure means of mechanical retention, though now there are chemical bonding agents (special type of dental glue) to add extra retention.  It reaches the highest strength in one week though it is already quite strong about 24 hours after the placement.

It has been around for hundreds of years and have been proven to be the strongest filling material for back teeth.  True, recently there had been controversy about the scare of amalgam due to “mercury.”  However, the American Dental Association have spoken otherwise.  Many of these these stemmed from misinformation to the consumers or intentions of pushing the more expensive, but prettier looking, restorative material by certain parties.  Everything has pros and cons, advantages and disadvantages. 

If you are pregnant, the American Dental Association does not recommend receiving silver fillings during pregnancy.  

Please do keep in mind that it is important to make an informed decision and that each case is different.

White Filling or Resin Fillings or Bonding

These are “plastic” fillings made to match your tooth color.  These fillings are placed most commonly in the front teeth to aid in esthetic.  It is made to stay in the tooth by mechanical retention and by chemical bonding agents (special type of dental glue).

It works well in the front teeth, because we do not chew with front teeth.  We use our front teeth to tear the food therefore there is a lot less load of pressure on these teeth.  Though the technology improves each day to the point where these fillings can withstand the strength and test of time like the silver filling, until we can achieve that goal, these fillings will require more frequent replacement on the back teeth than the silver fillings. 

Almost all dental insurances refuse to pay for white fillings on the back teeth.  But if you still prefer to have white fillings on your back teeth, no one should persuade you otherwise.
