White or Silver Fillings?
Here is what you need to know about your options in fillings to repair tooth decay.
Silver Colored Amalgam Fillings
For generations, dentists have repaired decayed teeth using silver colored (amalgam) fillings. They are a safe and affordable option for tooth decay. Amalgam is a mix of metals, including silver, tin, mercury, copper and zinc. Estimates show that over 100 million Americans have amalgam fillings in their mouths. Nevertheless, they require the removal of more tooth structure and can corrode over time, discoloring the enamel of the tooth that remains. The biggest disadvantage is their silver color, which keeps most dentists from applying amalgam fillings to the front teeth.
White Colored Composite Fillings
Composite white colored fillings are a blend of plastics and small glass particles. With these fillings, your dentist first removes the decay. A composite shade that best matches your tooth color is used together with a special curing light to harden each layer of filling material. The filling is also shaped to fit your tooth and polished to remain smooth.
Why People Like White Fillings
One of the main advantages of composites is that since it is the color of your teeth, it's almost impossible to see that the tooth had to be restored. Also, because these fillings bond directly to the enamel, they're strong and resist wear, usually lasting more than five years or longer. However composites are usually more expensive than amalgam silver color fillings.
Keeping Your White Fillings Healthy
To keep your composite fillings looking their best, you will need to have good oral hygiene. Brush your teeth twice a day with fluoride toothpaste and soft-bristled toothbrush and floss once a day. Limit sugary snacks and sodas and see your dentist regularly for exams and cleanings.
Every filling material has its pros and cons. White fillings are a cosmetic and durable alternative. Amalgam fillings are just as strong, long-lasting but less expensive than composites. Your preference notwithstanding, it's always wise to consult your dentist about which type of filling will function best for you.
