Tooth colored fillings may look better than silver fillings, but that’s not the only thing that they have going for them. There are several reasons why composite fillings are now the standard material used by dentists in their private practices.
They require less tooth preparation, allowing them to be smaller
Only the portion of the tooth that is decayed needs to be removed. The surrounding area is lightly conditioned and supports direct bonding between itself and the composite material. Metal fillings do not work this way, and require additional tooth structure to be removed so that they will be anchored into place by their shape.
They bond onto any surface
Unlike silver fillings that have to be held into place with wedged-shaped enamel, composite literally bonds to the pores of the tooth. That means they can be put on even smooth areas such as roots or on the edges of teeth where chips sometimes happen.
They can be placed on any tooth in the mouth
Because composite fillings look good and blend in with the tooth, they can even be used to repair decay or damage in the front teeth. If you have silver fillings that show when you smile or talk, you might want to ask your dentist about replacing them with composite ones.
There’s no mercury
Although silver amalgam has been used in dentistry for over a century, there are still some people that have reservations about the fact that a small amount of mercury is present inside of the metal alloy. With composite material there’s no link to the metal whatsoever, allowing people to avoid its use if they wish.
