Would you believe me if I told you that you can actually reverse your cavities and tooth decay naturally? Contrary to what we’ve believed by doctors and dentists, our bodies are very capable of repairing damages incurred on our teeth without fillings, painful dentist visits, and expensive procedures. Crazy, right!?

Is It Really Possible To Reverse Cavities?

Yes! Dr. Weston. A. Price, a dentist, discovered and detailed in Nutrition and Physical Degeneration, that there were many cultures of isolated villages around the world where the people there had perfect teeth, despite not having access to medical doctors or dentists. Dr. Price found that what these cultures had in common was their primitive diet and nutrition consisted of extremely high calcium and mineral content, and at least ten times the amount of fat-soluble vitamins from animal fats, such as butter, fish eggs, shellfish, and organ meats.

He found that cultures with similar genetic backgrounds, but with some eating a primitive diet and others with a modernized diet, had vastly different results concerning health and tooth decay. Those living on a primitive diet devoid of any processed food, sugar, or grains, were able to completely avoid tooth decay, while those eating a modernized diet of grains and processed foods had the opposite result.

Drs. Edward and May Mellanby, a husband and wife team, were the ones to originally discover that a vitamin D deficiency ultimately caused rickets. They believed that a diet should be purely based on whole foods that offer an adequate supply of vitamins and minerals, and to limit the intake of grains which can antagonize the effect of vitamin D and A. Yikes!

The Doctors’ Conclusion: Diet Directly Affects Oral Health

After years of research, these doctors’ all reached the same conclusion: tooth health and structure is largely determined by diet and nutrition, focusing on these 4 main factors:

  • Having enough minerals in the diet.
  • Having enough fat-soluble vitamins (A, D, E, and K) in the diet.
  • Eating too many foods high in phytic acid.
  • Eating too much sugar and processed food.

What Exactly Is Phytic Acid?

Phytic Acid is found in plant seeds and serves as the main form of storage  for phosphorus. Phosphorus is a natural mineral found in our bones, but too much of it can have adverse effects, such as leeching calcium from the bones making them brittle and weak. Phytic Acid derives only from plant material and is found mainly in grains, bran, soybeans, oatmeal, nuts, and seeds. From the Weston A. Price Foundation:

Phytic acid is the principal storage form of phosphorus in many plant tissues, especially the bran portion of grains and other seeds. It contains the mineral phosphorus tightly bound in a snowflake-like molecule. In humans and animals with one stomach, the phosphorus is not readily bioavailable. In addition to blocking phosphorus availability, the “arms” of the phytic acid molecule readily bind with other minerals, such as calcium, magnesium, iron and zinc, making them unavailable as well. In this form, the compound is referred to as phytate.

Modern agricultural practices include using a high phosphorus fertilizer, meaning your food ends up with more phytic acid content. Check out this article from the Weston A. Price Foundation detailing the phytic acid content in foods.

Phytic Acid’s Damaging Effect On Bone And Tooth Health

Most Americans, unfortunately, consume large amounts of phytic acid in foods due to a diet rich in processed foods which leads to tooth decay, mineral deficiencies, and osteoporosis. Quoted from the Weston A. Price Foundation:

Over the long term, when the diet lacks minerals or contains high levels of phytates or both, the metabolism goes down, and the body goes into mineral-starvation mode. The body then sets itself up to use as little of these minerals as possible. Adults may get by for decades on a high-phytate diet, but growing children run into severe problems. In a phytate-rich diet, their bodies will suffer from the lack of calcium and phosphorus with poor bone growth, short stature, rickets, narrow jaws and tooth decay; and for the lack of zinc and iron with anemia and mental retardation.

With a diet full of processed foods, nuts, grains, seeds, soy, sugar, vegetable oils, and low in animal fats and fat-soluble vitamins is guaranteed to result in diminished bone density, tooth decay, mineral deficiencies, and a host of other diseases and ailments.

Luckily for us, our bodies have the natural ability to heal our tooth decay through a process known as “remineralization”. Specialized cells found in the center of each tooth are able to regenerate dentin, which is the layer of tooth just below the enamel. The enamel can then effectively remineralilze itself from the outside, healing tooth decay and cavities. Just like how our bones heal after a break, our teeth can heal after tooth decay.

Drs. Edward and May Mellanby set out to prove this exact theory by doing a study on children with existing cavities. The children were put into three test groups:

  • Group One: Regular modernized diet of processed foods high in phytic acid.
  • Group Two: Regular diet plus vitamin D.
  • Group Three: Diet low of phytic acid plus vitamin D.

This is their results:



As you can see, the group consuming the most phytic acid with no vitamin D supplement continued to have tooth decay with little to no healing occurring.

In contrast, the group that ate a regular diet and supplemented vitamin D had some healing but still developed cavities while the group with the least phytic acid and most vitamin D in their diet showed very few new cavities and actually had their existing cavities healed!

That’s extremely promising!

How To Stop And Reverse Cavities


The first and most important step in reversing and remineralizing your teeth is to change your diet. This consists of three major components:

  • Having enough minerals in your diet.
  • Having enough fat-soluble vitamins (A, D, E, and K) in your diet.
  • Limiting and/or eliminating foods high in phytic acid from your diet.

So how do you ensure that you’re getting all the proper nutrients in your diet to combat tooth decay? Well, there are several important factors you want to consider, and include in your diet plan. Here’s what a good cavity reversal diet plan would look like:

  • Rich sources of animal foods like organic meat, fish, eggs, and bone broth.
  • Raw dairy products like cheese, milk, kefir, and grass-fed butter.
  • Raw and cooked vegetables, especially dark green leafy vegetables.
  • Only eat one piece of fruit first thing in the morning, or none at all.
  • Healthy fats like coconut oil, avocado oil, olive oil, and fish or fermented cod liver oil.
  • High vitamin D – lots of sunshine, or supplement with 5,000 IU of vitamin D.
  • Fermented grains, only in moderation, but none at all is best. You can buy raw breads and flour from Blue Mountain Organics.
  • Seeds, nuts, and beans that have been sprouted. You can also get sprouted nuts and seeds from Blue Mountain Organics, or you can make your own at home.
  • Lastly, absolutely NO packaged food, processed food, fast food, or sugar.

While it’s not really possible to completely eliminate phytic acid from your diet, there are many ways you can minimize your exposure to it in foods. For instance, if you choose to consume nuts, which are extremely high in phytic acid, soaking them overnight in a solution of water and salt, can greatly reduce the the phytic acid content. While it’s easier just to avoid these foods altogether, there are alternatives if you choose to eat them.

Grains are especially better soaked, sprouted, and fermented (like true sourdough), if you choose to consume them at all. I personally don’t consume grains on a daily basis, but if I do, I ensure they are the sprouted form and I only eat a very small amount. Avoiding foods that are high in phytic acid is the easiest way to go:



You can find an immense source of information on phytic acid in foods online here at the Weston A. Price Foundation website, or you can check out a great book by Rami Nagel called Cure Tooth Decay: Heal and Prevent Cavities with Nutrition.


Along with proper diet, supplements come into play as a very important addition to our daily diet. Most of the population is deficient in some key minerals and vitamins, ones that are crucial to bone and teeth health. The best supplements to take for improving teeth, and helping to reverse cavities are:

All of these supplements should be taken together, especially the vitamin D, calcium, and magnesium. The combination of these supplements, with a diet rich in whole organic foods, will help repair and rebuild damaged teeth, reverse cavities, and protect them against future damage.

Remineralizing Toothpaste

The second step in reversing cavities is to make a homemade remineralizing toothpaste. This is to be used alongside proper diet and nutrition to help speed up the remineralization process of your teeth. Combined with a few simple ingredients, you can start the healing process right away and help reverse your tooth decay. I’ve written a detailed article here on how to make your own remineralizing toothpaste.
