Are composite (white) fillings safe?
Composite fillings are a plastic material that is customizable to match your teeth. Because composite materials contain absolutely no mercury, some experts feel it is a safer option than the old black amalgam fillings of the past.
While most dentists believe amalgam fillings to be completely safe and appropriate treatment for dental decay, some dentists would rather not take that risk. Some patients complain of hot and cold sensitivity with amalgam fillings, as well. Because they are metal, they are better conductors than composites.
Additionally, we preserve more of your tooth structure when placing a composite filling as opposed to an amalgam filling because less prep work is necessary. While composites generally take a little more time because of the curing process, your filling will be as hard as it will get when you leave our office. That means you can chew on it right away, unlike amalgam fillings that must cure for hours before chewing on them.
While composites tend to cost a little more, the benefits of using them are many. Aside from the obvious aesthetic advantages, composite materials and techniques constantly improve making them as long lasting and reliable as amalgams. If you have questions about composite fillings, please do not hesitate to ask.
