White Wine May Be Bad For Your Teeth

Bacchus by CaravaggioA group of  researchers at Johannes Gutenberg University, reporting in the journal Nutrition Research,  have suggested that frequent drinking of white wine may damage the teeth.

In the lab, adult teeth soaked in white wine for a day had a loss of both calcium and another mineral called phosphorus to depths of up to 60 micrometers in the enamel surface, which the researchers say is significant.

The effect is pH-mediated, and is most noticeable with Riesling wines, and was exacerbated by brushing the teeth soon after drinking wine.  Red wines were noted to be much less damaging to teeth, and the researchers suggest that the deleterious effect of white wine might be mitigated by the ingestion of calcium-rich cheese.

A Tower Made from Human Teeth

This dentist no doubt inspires confidence in his patients with his tower made from 28,000 teeth from previous patients:

This 8ft tower of teeth is foul, and the summit of 15 years work by Yu Qian, a Chinese dentist who is trying to raise awareness about dental hygiene by word of mouth. Or, as it turns out, an awesome viral film gone global.

His piece of art is made from 28,000 human teeth (URGH). So far he has treated 100,000 patients, and ‘harvested’ 28,000 diseased teeth from his patients.

Tooth Grown from Stem Cells

Posted by Miss Cellania in Science & Tech on August 5, 2009 at 12:02 am

Scientists from the the Tokyo University of Science used mouse stem cells to grow a new tooth that worked like a charm in a mouse’s mouth. The cells were grown in a lab dish until a tiny tooth “bud” formed. It was then transferred to the jaw of a mouse where a tooth had been removed. The new tooth erupted through the gum in about five weeks, and was fully grown in seven.

The researchers, who repeated the experiment many times, also showed that the new, bioengineered teeth were fully-functional.

Dr Kazuhisa Nakao said: ‘Every bio- engineered tooth erupted through the gum and had every tooth component such as dentine, enamel, pulp, blood vessels, nerve fibres, crown and root.’

Importantly, the rodent recipients had no trouble eating.

If the technique can be used in humans, dentures may eventually be obsolete. The tooth shown in the picture also had a green fluorescent gene so it could be seen easily. Link -via Digg

Remember Daito Manabe from his painful looking face dance video? Well, he’s back with what in my honest opinion will replace all those god awful gold/silver/platinum/tin foil grills you see the young kids flashing about with a toothy grin these days. So, the next time you’re in a club or at a fancy soiree and the music picks up…keep an eye out for the hip kids to be flashing their multi-colored grills all up in your face.

These soaps are really cool, in a disturbing, nursing home kinda way. Apparently, they even have a nice minty scent.
