Tooth fillings are a tried and true method of restoring your smile’s form and function. But just because something has worked for over a century, doesn’t mean that it can’t be improved. Researchers at the OHSU School of Dentistry in Portland, Oregon, have worked to create a filling material that’s twice as resistant to breakage as standard fillings.
This new filling is composed of an extremely protective coating that can withstand more of the stresses that come with your normal chewing and oral conditions. The same team of researchers also developed an adhesive that’s 30 percent stronger than current filling adhesives. When used together, the new adhesives and composite make longer lasting dental restorations.
Dental restorations today typically last anywhere from seven to ten years. Under the pressures of chewing and bacteria they can crack, allowing gaps and more cavities to form. When this happens, the tooth becomes weaker and what began as a small case of tooth decay can turn into a much bigger, possibly life threatening issue.
Developing stronger materials that resist the damage caused by water, bacteria and chewing can provide great benefits to patients. As the frequency of repairing and replacing their fillings declines, patients can expect to save money, time, and avoid more serious problems with lengthy treatment.
