HOW MODERN TOOTH FILLINGS WORK
Traditionally, cavities were filled with silver amalgam fillings. But for years, there has been debate about whether the mercury content in amalgam fillings is harmful.
The Disadvantages of Amalgam Fillings
- Silver fillings are less attractive than tooth-colored composite resin fillings.
- Amalgam fillings expand and contract as temperature changes. The altered shape of the filling can allow bacteria to develop under the amalgam. In addition, expansion of a filling can eventually fracture your tooth, and a crown may be required to restore it.
- Silver fillings may eventually corrode and leak.
With the development of durable, tooth-colored restorative materials, silver amalgam fillings are often not the best choice for long-term dental health, functionality, and the appearance of your smile.
Composite resin fillings are not only durable and long lasting, but also attractive. Also, composite resin bonds to a tooth, restoring more of its original strength and function. Dr. Allen or Dr. Neumann will custom tint the resin to match your teeth, so your filling will look like natural tooth structure.
Another benefit: When placing an amalgam filling, healthy tooth structure must be removed just so the filling will stay in place. With composite fillings, only the decayed portion of the tooth must be removed, because the bond anchors the material tightly into place. This means that healthy tooth structure remains intact.
Benefit from a Tooth-Colored Filling
Treat a cavity discreetly and with better long-term benefits by choosing a tooth-colored filling instead of a metal one. To schedule an appointment with Dr. Allen or Dr. Neumann, call our dental office in Pella, IA, today at (641) 628-1121.
