4 Reasons to Update Your Old Metal Fillings

Posted in Fillings

There are a few good reasons why you should update your metal fillings to new white ones. If even one of these reasons is important to you, then that definitely justifies having your old restorations replaced.

1. White (tooth colored) fillings are more aesthetically pleasing.

Gone are the days of having a metal grin! Fillings can now be done with a composite resin material that resembles the color of natural teeth. Unless someone was to look very closely, no one would ever be able to count how many fillings you have.

2. Recurrent decay is common underneath aged metal fillings.

With temperature change, the metal expands and contracts faster than teeth do. This results in very small gaps around the filling, allowing cavity-causing bacteria in. This decay often goes undetected on x-rays because the metal filling is hiding it. Updating your old metal restorations is the ideal opportunity to clean out any decay that has settled in over time.

3. Tooth colored fillings create a more secure bond with the tooth.

Metal fillings don’t chemically bind to teeth. A larger amount of tooth structure has to be removed to provide a mechanical anchor for a metal restoration. Composite fillings form a chemical bond with teeth. This means that they don’t require as much tooth material to be removed.

4. Metal fillings could possibly leak mercury into your system.

The effects of mercury on the body’s nervous system is of great concern to a lot of people. If this concerns you as well, then updating your old fillings could give you peace of mind.

To find out whether or not your existing metal fillings qualify to be upgraded to white ones, visit your local dentist.
