Moline Mercury-Free Dentist

Around 1830, a new dental material was introduced in the United States called amalgam. Filings of an alloy of silver with some other metals were mixed with mercury, making a thick paste. In a few minutes, it would harden into a strong, solid dental restoration. It was used very successfully for many years. Many dentists still use it for their fillings, and dental schools still teach it.

But in the 1980s, there was a new technology developed. Composites, which had been used in dentistry for front teeth, were developed that had the strength to use as fillings on back teeth. We also developed the ability to bond composite to teeth.

Top is a an amalgam filling and bottom is Composite white filling Dr. Goebel hasn’t used any amalgam fillings since he left dental school. Not only does he feel that the bonding technology helps strengthen the tooth, but it avoids the use of any mercury. While the American Dental Association maintains that amalgam fillings are perfectly safe, many patients are still uncomfortable with the idea of having mercury in their mouths.

Advantages of Mercury-Free Composite Fillings

  • They bond directly to the tooth and make the tooth stronger.
  • Much less tooth structure has to be removed to restore a cavity. Dr. Goebel believes in trying to preserve as much natural tooth structure as possible.
  • There is less post-operative sensitivity. Metal fillings conduct hot and cold to the inside of the tooth, and it can take several weeks for that sensitivity to go away. Composites insulate the teeth.
  • Composite fillings restore the natural appearance of the tooth.
