Bioactive Glass Leads to Longer-Lasting Fillings

Dentists complete 122 million composite tooth restorations in the United States each year, according to Oregon State University (OSU). But the average lifetime of posterior dental composites is only 6 years. Bioactive glass may improve their durability and provide some of the minerals that have been lost to tooth decay.

“Bioactive glass, which is a type of crushed glass that is able to interact with the body, has been used in some types of bone healing for decades,” said Jamie Kruzic, a professor at the OSU college of engineering. The hard and stiff material can replace the inert glass fillers now mixed with polymers to make modern composite tooth fillings.

“This type of glass is only beginning to see use in dentistry, and our research shows it may be very promising for tooth fillings,” he said. “The bacteria in the mouth that help cause cavities don’t seem to like this type of glass and are less likely to colonize on fillings that incorporate it. This could have a significant impact on the future of dentistry.”

Bioactive glass is made with compounds such as silicon oxide, calcium oxide, and phosphorous oxide, and it looks like powdered glass. Its antimicrobial effect is attributed, in part, to the release of ions such as those from calcium and phosphate that have a toxic effect on oral bacteria and tend to neutralize the local acidic environment.

“Almost all fillings will eventually fail,” Kruzic said. “New tooth decay often begins at the interface of a filling and the tooth and is called secondary tooth decay. The tooth is literally being eroded and demineralized at that surface.”

Tooth Cavities

Tooth cavities aren't uncommon - but with the right dental health know-how, you can help prevent them. It all starts with proper brushing, daily flossing, and fluoride. Get the details right here.

What Causes Tooth Cavities?
Cavities are holes in the teeth resulting from acid attack. They generally start in the enamel, but can spread to the softer inner layer of the tooth. Tooth cavities are caused by decay that can occur when foods containing carbohydrates become trapped between teeth, and are not completely removed with brushing and flossing. Bacteria living in the mouth digest these foods, generating acidic byproducts that can eat away at tooth enamel.

Help Prevent Tooth Cavities
Fluoride, which is found in most public drinking supplies, some mouth rinses, and Crest toothpastes, helps prevent tooth cavities by slowing the breakdown of enamel and speeding up the remineralization process. Check with your dental professional to see if your drinking water is fluoridated. If it isn't, he or she may recommend that you use high concentration fluoride treatments.

To help strengthen weak spots in tooth enamel, and help prevent the early stages of tooth decay, brush regularly with a fluoridated toothpaste, floss daily, and visit your dental office regularly for professional cleanings.
