Your dentist can determine if you need to replace metal fillings

Good question. Your mouth may be a hodgepodge of fillings, crowns, and bridges accumulated over a lifetime of dental visits. Are there valid reasons to replace metal fillings with tooth-colored versions other than cosmetic? If you decide to replace your silver amalgam fillings, what are the methods your Northern Virginia dentist recommends?

Why Fillings Need To Be Replaced

The fact is that dental work does not last forever. Any dental material will wear down over time because of the stress our teeth endure.

Although fillings may last for many years, eventually all fillings need to be replaced.

There are several factors that contribute to the longevity of your original filling or restoration:

  • type of filling
  • the size of the cavity
  • oral care and hygiene habits
  • dental problems, such as teeth grinding

Now that you’ve come to terms with the common misconception that your filling will last forever, why would you choose white, composite restorations?

The Problems With Silver Fillings

There were reasons why dentists used amalgam fillings for so many years. The material was cheap, durable and easy to use.

So why are many dentists now using other materials?

1. Tooth decay and cracks

With time metal fillings start contracting, resulting in small spaces where bacteria can start wearing away your tooth enamel. This may cause cracks and fractures in your teeth which are also susceptible to decay. Cavities may form under amalgam fillings which are very difficult to identify because they are invisible by x-rays.

2. Discoloration of your teeth

The silver in the dental material can start showing through tooth enamel making your teeth appear gray and dead.

3. Mercury toxicity

Many people are concerned about their exposure to mercury. Mercury damages our internal organs and nervous system and may contribute to or cause auto-immune disorders or diseases such ALS, Alzheimer’s, multiple sclerosis, and Parkinson’s disease.
