Have you ever had one of those nights when you’re starving but had no food in the house? Struggling for ideas you scrounge up two slices of bread and a tube of toothpaste- it almost looks like a marshmallow fluff sandwich. For those daring enough to try it, chances of cramping and diarrhea await due to the various additives such as fluoride.

It’s the eternal dilemma: toothpaste tastes great, and yet if we eat it we’re told that we can get sick or in the case of copious amounts even die. Why do we torture ourselves by keeping little tasty tubes of poison around the house?

Soon we may not have to anymore thanks to Neonisin, an all-natural and completely edible toothpaste that is just as efficient against germs as regular chemical-laden brands.

The active ingredient in Neonisin is Nisin, a peptide widely used as a natural preservative which kills microorganisms. Nisin can be harvested from lactic acid bacteria found in soy bean curd (okara in Japanese).

Okara is widely eaten in Asia, Nisin and all, with no adverse effects. Nisin has also recently made news for its effectiveness against oral cancers. The substance itself is odorless and tasteless.

So in the formulation of Neonisin, flavoring is added. However, all ingredients are natural according to company rep Daisuke Teshima:

“First it has soy bean curd and plum extract. There’s also mint oil and the thickener is made from corn; it’s totally free of synthetic chemicals. All of the raw materials are from plants including the preservatives and fragrances. It doesn’t rely on limited resources like petroleum either. It’s an organic product.”

He goes on to explain that while other natural toothpastes are on the market, they end up weaker than their chemical counterparts. Neonisin has the all-natural components of organic toothpastes but also rapidly disinfects like conventional pastes.

Obviously an edible toothpaste has uses beyond people with empty cupboards and tummies. It’s safe for children, disabled people and the elderly who are at risk for accidental ingestion. This substance has no impact on the gastrointestinal system.

Neonisin is expected to hit the shelves around early summer, but a writer for Excite was able to get a sample early. The website explains Neonisin isn’t a paste exactly. It’s more like a gel. This is kind of unsettling at first, but the taste of mint and plum allegedly provided a “taste full of exhilaration” and their mouth was left feeling clean afterward. Apparently after deliberately eating some of the stuff there are no side-effects whatsoever other than the feeling you’re doing something wrong.

One 75 ml (2.5 oz) tube of Neonisin is expected to cost 840 yen (US$8.90) which is steep but not outrageous considering it’s the first run of an organic, safe, and effective toothpaste which may even fight cancer. Color us interested!
