Grape seed extract found to contain powerful nutrients that prevent tooth decay


Grape seed extracts can promote teeth durability and stave off tooth decay, a recent study in the Journal of Dental Research revealed. According to a team of researchers at the University of Illinois at the Chicago College of Dentistry, natural compounds found in grape seed extracts fortify the teeth’s dentin. Dentin is the dental tissue beneath enamel, which is mostly made of collagen. The researchers also noted that grape seed extracts may increase the life span of dental fillings.
Dental fillings can be made up of amalgam or composite resin. Researchers said dental amalgams are usually made of a combination of heavy metals such as mercury, silver, tin, or other materials. Dental amalgams are known for their low cost and long life span of 10 to 15 years or higher. On the other hand, composite-resin fillings are more aesthetically-designed, as the plastic and fine glass particles allow dentists to use filling colors that match the patients’ teeth. However, composite fillings last only five to seven years.
A federal report found that more than 90 percent of adults aged 20 to 64 have cavities. In order to address cavities, dentists take out the decay or dental caries using a drill and plug it up with a filling. According to researchers, resins need to bind with the dentin during the filling process. The researchers noted that the area between the teeth and the resin, called interface, remained a weak point that often led to the breakdown of teeth restorations. The health experts said that secondary caries and margin breakdown were the top causes of failed adhesive restorations. In addition, the research team noted that adhesive interface breakdown remained a major hurdle despite major advances in dental restorative materials. (Related: Strengthen your teeth the natural through these dietary choices)
“When fillings fail, decay forms around it and the seal is lost. We want to reinforce the interface, which will make the resin bond better to the dentin. The interface can be changed through the use of new natural materials…The stability of the interface is key for the durability of such adhesive joints, and hence, the life of the restoration and minimizing tooth loss,” researcher Ana Bedran-Russo said in DailyMail.co.uk.
The recent study found that a combination of grape seed extracts and plant-based oligomeric proanthocyanidins prompted damaged collagen to repair itself. According to Bedran-Russo, interlocking the resin and collagen-rich dentin offered better adhesion and did not rely on moisture.
The study was funded by National Institute of Dental and Craniofacial Research.

Oral health status in the U.S.

Oral and dental health issues remain a major burden in the U.S. Data from the Centers for Disease Control and Prevention (CDC) revealed that nearly 18 percent of children aged five to 19 years old had untreated dental caries in 2015. The CDC also showed that more than a quarter of adults aged between 20 and 44 years had the same condition in 2015. In addition, CDC data revealed that 83 percent of patients aged two to 17 years made dental appointments in 2015, while 62 percent of adults aged 18 to 64 and 62.4 percent of seniors over 65 years did so in the same year.
Furthermore, the CDC noted that disparities in oral health continue to exist across ethnic groups in the U.S. According to the CDC, non-Hispanic blacks, Hispanics, American Indians, and Alaska Natives generally have the worst oral health of any racial and ethnic groups in the country. Mexican American and black, non-Hispanic children have the highest rates of tooth decay among young patients aged two to eight years old. On the other hand, blacks, non-Hispanics and Mexican Americans were nearly twice as likely to suffer untreated tooth decay compared with white, non-Hispanic adults.

Why you must DEMAND made-in-the-USA dental crowns from your dentist

When we go to the dentist to repair or replace missing or cracked teeth, we usually don’t ask questions about what they put in our mouths. Because of this, tens of thousands of Americans could have dental fixtures in their mouths that contain toxic chemicals.
These metal and ceramic inserts, bought on the cheap, are imported from China and other Asian countries. According to dental experts, these cheaper products are often made in unregulated laboratories and can contain dangerous levels of lead and other chemicals — such as beryllium and cadmium — that could harm the human nervous system.
Due to their low price and quick service, many American dentists now favor these Chinese, toxic dental fixtures without passing the savings to the client. U.S. dentists have admitted using Chinese labs that charge about one-fifth of what local labs typically charge. As reported by the Daily Mail Online, dentists can take an impression of a client’s tooth, send it by express mail to China and receive a crown within four days.
“In the end, the whole system is profiteering. Any savings made by outsourcing the work to China are never passed on to the patient,” said David Smith, a board member of the Association of Dental Laboratories.

Lead poisoning linked to Chinese dental fixtures

Given China’s notoriety for cheap, fake, and toxic food and building materials, it doesn’t come as a big surprise that their dental fixtures can’t be trusted either.
At least four known cases of lead poisoning caused by Chinese dental fixtures have been reported in the United States. When these fixtures were tested in a laboratory, data revealed that some of them contained 210 times the acceptable amount of the heavy metal.
The toxic dental practice came to light when a 73-year-old Ohio woman became sick after a U.S. dentist installed a dental crown made in China. When the crown, among other crowns from Chinese labs, were tested, lead concentrations of nearly 500 parts per million were found. This is five times more lead than the limit set for toys sold in America.
While it is easy to pull lead-tainted toys off the shelves when a problem arises, it’s nowhere near as easy if the contaminated product is a dental fixture in someone’s mouth, noted David Smith.
Once inhaled or ingested, lead can harm the body in several ways. Symptoms of lead poisoning include high blood pressure, abdominal pain, headaches, memory loss, mood disorders, infertility, miscarriages, mental decline, and joint or muscles pain.

China’s quality control leaves something to be desired

Though the import of medical devices is strictly regulated, the supply of dental components is harder to control. While they all should carry a safety mark, it is often hard to check if the manufacturer used safe materials. Unlike the loose safety standards in China, laboratories in Europe or the U.S. get routine, unannounced inspections. They must follow strict laws to make sure crowns, bridges, and dentures are safe and toxin-free.
For the sake of your health, the next time you visit your dentist, be sure to ask where that set of dentures, bridges, or crowns came from. If your dental office offers steep discounts on dental work, chances are high the fixtures are imported from China.
Know that as a customer, you have the right to inquire about where dental materials have been made. If your dentist tries to dodge the question or he doesn’t want to give you a straight answer, then find another dentist who uses safe materials from trusted U.S.-based labs.
To be sure that no questionable chemicals end up in your body, opt for a holistic dentist instead. Is this term new to you? Click here to learn more about the benefits of holistic dentistry.
