Price-Pottinger Story
6 min 45 sec

Start with nutrition. The rest will follow. Above is an introduction to the Price-Pottinger Story: how sound nutrition will give you the best teeth without any cavities. This goes into detail about the processing methods as harmful to the long term nutritional value of our foods.

This next summary goes into more detail about the particular vitamins and minerals and social production processes that preserve the vitamins and minerals for human use. Rami Nagel's summary of the Price-Pottinger story is good because he starts with the current medical surgery method and story about mere external bacteria attacking the teeth and calls into question how this makes little sense on the face of it. He looks like a dentist or missionary, though, no, he is a concerned parent who wants to help his child. Once he did, as a good human being, he wanted to share the information in an e-book and free information in this video and a website. If only all parents would do the same research and act on their empathy we would be in much better shape.

Cure Tooth Decay & Cavities 1 of 3 (Nutrition and Physical Degeneration)

Nagel summarizes the importance of nutritional therapies to remove all tooth decay and regrow tooth dentin and enamel in damaged teeth. Particularly important is the synergy of getting a lot more

1. vitamins A, B, D, and K (the fat soluable vitamins),
2. Omaga 3 (instead of 6; the 'fat base' for the vitamins in typical traditional cultural foodways of grass-fed animals and different seafoods),
3. along with Calcium and Phosphorous in much larger doses than people typically get nowadays from processed foods.

He summarizes Price-Pottinger's data about the common elements of diets globally with the least tooth decay: grass-fed meats, seafoods, and certain types of high vitamin butter and raw milk products from grass-fed cows. This synergy gells into capacities to keep bones in healthy states of repair. (Remember the Pottinger cat experiment and compare it to the human skull bone data he gathered as well).

In short, the importance of 'avoiding the foods of commerce' is stressed. What can additionally be stressed is avoiding fluoride.

(Personally, I was confused by Nagel's talk in one area: I don't understand the internal inconsistency of Nagel's dislike of raw foods--when Pottinger found the opposite. According to Pottinger's original opinion, half cooked and half raw would work regardless what Nagel says in the video.) Poor nutrition will set you up for a lifetime of defending yourself against people who want to do this to you:

Mercury amalgam is only the product of mass ignorance of the centuries of the past. It is hardly a solution for the healthful future.

Whiten Your Teeth With Strawberries

Dr. Mercola
September 27 2007

Tooth whitening is the leading dental procedure requested by people under the age of 20 and between the ages of 30 and 50.

In the last 10 years alone, this procedure has exploded by 300 percent, according to The American Academy of Cosmetic Dentistry.

Perhaps one reason for the explosion has to do with the vast numbers of people having their teeth whitened, which then sets a new standard for how "normal" teeth are supposed to look. Even if your teeth are a healthy shade, they may look yellow when compared to the pearly whites of celebrities and, now, the average person walking down the street.

The problem with most current tooth-whitening products, both over-the-counter versions and those performed in your dentist’s office, is that they use hydrogen peroxide to whiten your teeth.

This is not your best choice because peroxide can cause your teeth to become sensitive.

Additionally, hydrogen peroxide forms radical intermediates that can damage and destroy your gums and nerves.

What causes your teeth to become discolored in the first place? Tooth discoloration is caused by colored molecules such as tannins and polyphenols -- found in red wine, coffee, and tea -- which become absorbed by your tooth enamel’s surface.

Cigarettes, blueberries, and other foods that contain dark pigments can also discolor your tooth enamel, as can certain medications. Some of the staining can be removed by brushing, but over time the compounds can seep into your enamel.

If you’re looking for a safer alternative to brighten your teeth, you can try this simple trick:

* Crush one ripe strawberry and mix it with 1/2 teaspoon of baking soda.
* Spread the mixture onto your teeth and leave on for five minutes.
* Brush your teeth with a little toothpaste (non-fluoride, of course) and rinse.

This natural mixture works because of the malic acid it contains, which acts as an astringent to remove some of the surface discoloration on your teeth.

Though this method is perfectly safe to use on occasion, don’t use it too often (no more than once a week) because the acid could potentially damage your tooth enamel.



FDA Clears Laser for Tooth Whitening

The FDA has issued clearance for the use of diode lasers for tooth whitening -- an in-office process that may be faster than some technologies, and more accessible than others.

The number one elective procedure chosen by dentistry patients is teeth whitening, and the number of people doing it is growing rapidly.

For years, dentists have performed either at-home bleaching procedures or in-office techniques.

In the at-home procedures, a patient typically wears a peroxide-containing mouthguard either twice a day or overnight for 2 weeks.

For in-office procedures, the dentist applies a bleaching agent to teeth and exposes the teeth to a high-intensity (sometimes laser) light to restore whiteness.

Biolase's tooth whitening system is based on the use of an 810 nanometer (nm) diode laser in combination with a whitening gel.

Other types of lasers that operate on different wavelength frequencies -- such as the 488 and 514 nm wavelength argon laser -- have been available in the US for bleaching treatments for some time.

The diode laser offers both patients and dentists advantages over other lasers -- lower cost and increased availability. And it is more convenient than at-home procedures.

If you have a take-home bleaching tray kit you have to go a couple of weeks with a lot of discipline, and it's not user-friendly. The system may be superior to some in-office procedures, including ones that use light to speed the process.

According to the American Dental Association, these techniques can take more than one office visit lasting 30 minutes to an hour per visit.

That procedure works quite well but ties up 2 hours of a patient's time. This system will treat the whole mouth in a few minutes.

We can do a whole arch of teeth in 15 seconds.

The diode laser's ability to completely bleach an entire mouth in under 2 minutes -- repeating the process approximately once every 2 to 3 years -- will go a long way to satisfy the hunger of what is estimated to be an almost $1 billion demand for tooth whitening annually.

Many dentists across the US have already acquired the device -- making its use for tooth whitening both cheaper and more accessible for patients.

Lasers, and the diode laser in particular, do have many advantages over other tooth bleaching methods. A laser is a wonderful way to pinpoint the problem. One tooth may be yellower than another, for example, and a laser can deal with each tooth differently.

Also, a diode laser, specifically, is extremely convenient for dentists since it's about the size of an answering machine.

Laser light is generally a much faster way to activate the bleaching process and that it is much less sensitizing, resulting in significantly less stress on the nerve and the pulp of the tooth.

But yellow-toothed yuppies may want to think twice before stampeding their local dentist demanding a lasered return to their gleaming glory days.

There is a concern though as most people don't really know if they have large fillings or caps -- they might not know that they have those in their front teeth, and if you start the bleaching procedure on teeth like the laser you lighten the teeth but the caps and the fillings stay the same shade. So many people are not really good candidates for this procedure.

Dr. Mercola's Comment:

Many people are bleaching their teeth anyway. This certainly seems a far safer and less toxic alternative to bleaching which can cause some damage if done improperly.

A new Canadian tool can re-grow teeth say inventors, with ultrasound treatment

Wednesday, June 28, 2006 (AFP)

Snaggle-toothed hockey players and sugar lovers may soon rejoice as Canadian scientists said they have created the first device able to re-grow teeth and bones.

The researchers at the University of Alberta in Edmonton filed patents earlier this month in the United States for the tool based on low-intensity pulsed ultrasound technology after testing it on a dozen dental patients in Canada.

"Right now, we plan to use it to fix fractured or diseased teeth, as well as asymmetric jawbones, but it may also help hockey players or children who had their tooth knocked out," Jie Chen, an engineering professor and nano-circuit design expert, told AFP.

Chen helped create the tiny ultrasound machine that gently massages gums and stimulates tooth growth from the root once inserted into a person's mouth, mounted on braces or a removable plastic crown.

The wireless device, smaller than a pea, must be activated for 20 minutes each day for four months to stimulate growth, he said.

It can also stimulate jawbone growth to fix a person's crooked smile and may eventually allow people to grow taller by stimulating bone growth, Chen said.

Tarek El-Bialy, a new member of the university's dentistry faculty, first tested the low-intensity pulsed ultrasound treatment to repair dental tissue in rabbits in the late 1990s.

His research was published in the American Journal of Orthodontics and Dentofacial Orthopedics and later presented at the World Federation of Orthodontics in Paris in September 2005.

With the help of Chen and Ying Tsui, another engineering professor, the initial massive handheld device was shrunk to fit inside a person's mouth.

It is still at the prototype stage, but the trio expects to commercialize it within two years, Chen said.

The bigger version has already received approvals from American and Canadian regulatory bodies, he noted.

3D Dental Implants
Prosthodontists Devise Technique To Insert Dental Implants In A Single Surgery

October 1, 2007 — Researchers find that by imaging the mouth with a 3-D CT scan, they are able to create and insert a complete dental implant in one day. Instead of waiting for six months between placing the implant and the crown, this imaging technique allows the surgeon to locate the exact spot to place the implant. As important is the technique of immersing the surface of the implant in an acid bath, followed by an anodic electronic charge, to create a porous surface, hastening the fixation of the implant to the bone.

About 100 million Americans are missing teeth. But dentures or crowns can look unnatural and don't last forever.

For years, Hady Koraym suffered with bad, weakened teeth. "I always had like, um, pain with cold drinks and hot drinks," Koraym says.

To help stop his suffering, dentists pulled most of his teeth, leaving him without a smile. Now, a new 3-D dental implant procedure gave Koraym permanent teeth in just one hour.

"Most of the patients, they come out with a smile," says Liene Molly, M.D., Ph.D., D.D.S., periodontist from the University of Maryland Dental School in Baltimore, M.D. Traditional implants can take almost a year to complete. The new procedure is a faster, less painful solution for missing teeth.

"The traditional way of having implants is having two surgeries. So, now we can reduce it to only one surgery. That's very pleasant for the patient," Dr. Molly says. Periodontists first use CT scans to make a 3-D model of a patient's mouth. Then, using the model as a guide, doctors locate the exact spot in the mouth to place the implant and crown on top, all in one, minimally invasive surgery.

"You can visualize the bone. You can visualize how the teeth will be and how they can come together in one area," says Deborah Armellini, D.D.S., prosthodontist from the University of Maryland Dental School in Baltimore, M.D. Prosthodontists say the new procedure is a more accurate and more natural looking solution for patients wanting a return to eating, drinking and smiling with confidence.

"The most exciting thing for me is the ability to give a higher quality of life for patients." Dr. Armellini says. "Now, I feel very good," says Koraym.

Patients are put under local anesthesia during the procedure. To find a dentist performing the new implant procedure, contact the University of Maryland Dental School at:

BACKGROUND: Guided dental surgery based on three dimensional scans, new biomaterials, and what dentists call immediate 'loading' (installation) of the crown over a dental implant now makes it possible to get a complete tooth replacement in just one day. The one-day implant is now possible because the surfaces of the implants have been modified to enhance the rate of its fixation to the bone. The implant surface is treated by immersing it in an acid bath, followed by an anodic electronic charge to create a porous surface. The implant incorporates TiUnite as a replacement bonding agent, a biomaterial made of titanium that actively enables integration with human bone and soft tissue growth around the implant at the gumline. This allows the implant to look more natural, since there is no dark line where the implant and bone are connected.

BENEFITS: Getting an implant used to be a six-month procedure, first placing the implant in the bone and then waiting six moths for the bone to heal before placing the crown on top. With immediate loading, it's now possible to insert the crown the same day the implant is placed. At the same time, new 3D computerized tomography (CT) scanning techniques enable dentists to model and plan the restoration visually from start to finish. Looking at the converted CT scan image in a computer software program, dentists can inspect the bone in every direction, as if they were holding it in their hands. It removes the need for the surgeon to loosen the gum around the bone for inspection, and allows the fabrication of temporary teeth before the surgical procedure. This will make it possible to get a natural-looking dental implant from a regular dentist in just one day, with no need to visit a specialist. There is also less swelling, bruising and inflammation for the patient, in addition to spending less time in the dentist's chair.

ANATOMY OF A TOOTH: We think of teeth as being the part visible above the gum, but this is only the tip, or crown, of a tooth. There is also a neck that lies at the gum line, and a root, located below the gum. The crown of each tooth has an enamel coating to protect the underlying dentine. Enamel is even harder than bone, thanks to rows of tightly packed calcium and phosphorus crystals. The underlying dentine is slightly softer, and contains tiny tubules that connect with the central nerve of the tooth within the pulp. The pulp forms the central chamber of the tooth, and is made of soft tissue containing blood vessels that carry nutrients to the tooth. It also contains nerves so teeth can sense hot and cold, as well as lymph vessels to carry white blood cells to fight bacteria.

ABOUT CAT SCANS: CAT (Computerized Axial Tomography) scans are similar to conventional X-ray imaging, but instead of imaging the outline of bones and organs, a CAT scan machine forms a full three-dimensional computer model of the inside of a patient's body. Doctors can even examine the body one narrow slice at a time. The X-ray beam moves all around the patient, scanning from hundreds of different angles, and the computer takes all that information to compile a 3D image of the body.
