3D printed tooth

Lost a tooth? No problem, just print another. A strange notion, but one that Dutch researchers are trying to make a reality with 3D-printed teeth made from antimicrobial plastic.

Scientists in the Netherlands developed the material by adding antimicrobial salts to existing dental resin (the stuff that dentists use to fill your cavities). The resulting mix is hardened with ultraviolet light and used to print artificial teeth.

When the material was tested by exposing it to human saliva and Streptococcus mutans, the bacterium that causes tooth decay, it killed over 99 per cent of all bacteria. “[It kills] bacteria on contact, but on the other hand it’s not harmful to human cells,” said Andreas Herrmann, a chemist involved in developing the material.

Repairing Teeth Without Fillings

New dental technique repairs damaged teeth naturally, negates need for injections, drillings and fillings

(NaturalNews) In an effort that aligns entrepreneurial spirit with the body’s natural ability to restore health, experts at King’s College London have developed a way to put dental fillings by the wayside and, instead, help teeth heal themselves. (1)

Rather than drilling into an affected tooth and filling it with material to build up its structure again, a damaged tooth can instead be treated with the help of their new technology, Electrically Accelerated and Enhanced Remineralization (EAER), a technique that uses a small electric current to speed up a tooth’s natural remineralization process and, in turn, repair teeth without the need for drilling, injections and fillings. (1, 2)

Professor Nigel Pitts of King’s College London’s Dental Institute says it’s a healthy and affordable way to keep teeth in good shape, and one that’s long overdue.

“The way we treat teeth today is not ideal,” he said, explaining the seemingly never-ending cycle of drilling, filling and refilling that a dental patient often experiences. “Not only is our device kinder to the patient and better for their teeth, but it’s expected to be at least as cost-effective as current dental treatments. Along with fighting tooth decay, our device can also be used to whiten teeth.” (2)

King’s College is involved with a project called MedCity, which was launched by London mayor Boris Johnson in an effort to encourage entrepreneurship in the London-Oxford-Cambridge life sciences sector.

How the new technology treats damaged teeth

EAER’s low-frequency currents allow remineralization, a naturally occurring process in teeth that keeps them strong and healthy, to take place faster and deeper in the tooth, negating the need for traditional fillings. This new technique simply involves isolating elements in the mouth such as saliva that can get in the way of this healing process, then using the EAER technique to drive the natural minerals into the tooth. (3)

Pitts said that by using “the electrical method, we can achieve remineralization that would have taken weeks and we can do it an order of magnitude faster and better.” (3) His goal is to have this technique in place in British dental offices within three years; furthermore, he’s currently working with international dental groups in an effort which may make strides in the United States, where dental regulations differ from those in Britain. (3)

In addition to many people having a phobia when it comes to visiting the dental office, the materials that are often used — namely amalgam, the silver-colored fillings — contain mercury, a toxin that is linked with neurological disorders such as Alzheimer’s disease, Parkinson’s disease and autism. (4)

Amino Acid Treatment for Reversal of Tooth Decay

Researchers at the University of Leeds have developed a peptide-based fluid known as P 11-4. When applied to a decayed tooth, P 11-4 forms a gel-like scaffold that attracts calcium to help rebuild your tooth. As the University of Leeds reported in a press release:

“In practice, this means that when applied to the tooth, the fluid seeps into the micro-pores caused by acid attack and then spontaneously forms a gel. This gel then provides a ‘scaffold’ or framework that attracts calcium and regenerates the tooth’s mineral from within, providing a natural and pain-free repair.”

When the fluid was tested on a small group of adults with early tooth decay, results showed P 11-4 successfully reversed the damage and regenerated tooth tissue. This is the latest data from what appears to be a promising new dental strategy. Similarly, in 2008 scientists were also able torebuild dentin and remineralize some parts of the teeth with the help of a calcium-containing solution of ions.

Regenerating your tooth from within is a far superior option to the “drill-and-fill” model currently used today, and it appears to be a technique that may soon be widely available in dentists’ offices. Aside from the obvious benefit of tooth regeneration while sparing people the pain and fear of having a tooth drilled, this new procedure could virtually obliterate the use of toxic mercury fillings (if our efforts don’t get them banned first!) …

If You Have a Cavity, Resist This Archaic Dental Procedure

The very process of “filling and drilling” a cavity is a rather outdated practice, but so far there has been no other practical solution to remove the damaged areas of a tooth and “repair” it. But, adding insult to injury, about 50 percent of U.S. dentists are still using mercury to fill cavity-ridden teeth — even though exposure to mercury, the most toxic and more vaporous of the heavy metals, can harm your kidneys, permanently damage your child’s developing neurological system, and even kill your unborn child in the womb!

To implant amalgam, a dentist drills out healthy tooth matter in order to carve the crater necessary for amalgam placement — a primitive process that irreversibly weakens tooth structure. With a damaged tooth structure and with a metal-based filling that expands and contracts with temperature changes, teeth with amalgam are much more likely to crack years later, necessitating additional dental work.

Amalgams are quick and easy. Dentists make more money per chair per day implanting mercury. For factory-style dentistry, where teeth represent dollar signs instead of part of a human being, dentists drill, fill, and bill. The term “drill, fill, and bill” is a joke aspiring dentists learn in dental school. But when it comes to mercury – it’s no joke. Please realize that mercury vapor from amalgams passes readily through your cell membranes, across the blood-brain barrier, and into your central nervous system, where it can cause psychological, neurological, and immunological problems.

Yet, even though it may be a few years before P 11-4 and other tooth-regenerating fluids are widely available, there are solid alternatives to mercury fillings available right now. One of the most popular is resin composite, which is made of a type of plastic reinforced with powdered glass. Unlike amalgam, resin composite does not require the removal of significant amounts of healthy tooth matter. Over the long term, composite preserves healthy tooth structure and actually strengthens teeth, leading to better oral health and less extensive dental work over the long-term.

A lesser-known alternative is atraumatic restorative treatment (also called alternative restorative treatment or ART), which relies on adhesive materials for the filling (instead of mercury) and uses only hand instruments to place the filling, making it particularly well-suited for rural areas of developing countries.

Preventing Cavities 101: The Secret to Healthy Teeth

Tooth regeneration is certainly a step up from using toxic substances like mercury to fill your teeth. But do you know what’s evenbetter than tooth regeneration? Protecting your teeth and preventing cavities in the first place.

When it comes to oral hygiene and preventing cavities, there’s a virtual war going on. If you listen to conventional health agencies’ and your dentist’s advice, you may still believe that fluoride is the answer.

Think again!

The only way you can believe this misguided advice is if you completely ignore the science. Good oral health and strong, healthy teeth are NOT the result of drinking fluoridated water and brushing your teeth with fluoridated toothpaste. Rather it’s all about your diet.

Dr. Weston A. Price, who was one of the major nutritional pioneers of all time, completed some of the most incredible research on this topic back in the 1900s, and it is still very much relevant today. What he found, and documented in his classic book Nutrition and Physical Degeneration, is that native tribes who were eating their traditional diet had nearly perfect teeth, and were almost 100 percent free of tooth decay — and they did not have toothbrushes, floss, toothpaste, or root canals and fillings.

But when these tribal populations were introduced to sugar and white flour, guess what happened … their health, and their perfect teeth, rapidly deteriorated. By avoiding sugars and processed foods, you prevent the proliferation of the bacteria that cause decay in the first place.

Most people whose diet includes very little sugar and few processed foods have very low rates of tooth decay. So the simple act of limiting, or eliminating sugar, and avoiding processed foods — along with regular cleanings with your natural mercury-free dentist — will ensure that your teeth and gums stay healthy and cavity-free naturally.

Growing New Teeth from Stem Cells

Science with real bite: Full set of teeth grown in the lab

By FIONA MACRAE

Last updated at 5:26 PM on 13th July 2011

Scientists have grown fully formed teeth from stem cells.

The artificial teeth looked like the real thing, were sensitive to pain and could chew food.

The breakthrough was made on mice but could pave the way for those who lose teeth to decay or injury being able to ‘grow’ replacements.

The researchers harnessed the power of stem cells – ‘master cells’ which have the potential to be used to grow any part of the body – to generate teeth.

Two types of stem cell which between them contain all the instructions for making teeth were mixed together and grown in the lab in a mixture of chemicals and vitamins that started their transformation.
