How to Remineralize Teeth Naturally & Reverse Tooth Decay

How to reverse tooth decay and cavities naturally

Do you and your kids brush and floss regularly and limit sugar and still get cavities?

Have any of your kids needed to have braces?

Has your child under 6 had signs of tooth decay?

Ever wish you could reverse those things?

If you are like me, you were raised with the notion (likely told by your dentist) that sugar and bad genes cause tooth decay and that if you were getting tooth decay as a child, you needed to cut back on sugar. You likely also believe that genetics determine tooth spacing and that your genetics might have doomed you to braces…

I believed all that stuff too… but as it turns out, there is more to the story!

What Really Causes Tooth Decay?

There is a lot of evidence showing that diet had a tremendous impact on oral health (even more so than brushing in some cases) and that there had even been cases of cavities reversing.

As I thought about this, it made sense…

Why would bones and other tissue be able to heal and regenerate, but not teeth?

How did other populations throughout the world have great oral health, no cavities and no need for braces when they didn’t even have access to modern dentistry?

As Dr. Weston A. Price (a dentist) found and detailed in Nutrition and Physical Degeneration, there were cultures throughout the world who had perfect teeth despite no access to dentists or modern toothpaste, while similar cultures with different diets had very high rates of tooth decay.

He found examples of cultures with similar genetic backgrounds with some living in primitive type societies and eating primitive type diets and others who ate a modernized diet. He found that many primitive cultures were able to completely avoid tooth decay and the many oral health problems we struggle with today.

Price hypothesized that several dietary factors contributed to this difference in oral health.

Sir (Dr.) Edward Mellanby (he discovered Vitamin D) and his lovely wife Dr. May Mellanby were also influential in discovering the roles of nutrients in oral health. These two contributed much research in the areas of bone and tooth health and mineral absorption.

In fact, it was Edward who discovered that Vitamin D deficiency caused rickets. They also discovered that tooth structure is determined during a child’s growth, and that poorly formed teeth are more likely to decay (pretty logical).

The Doctors’ Conclusion: Diet Affects Oral Health

These doctors all reached the same conclusion after years of research, mainly that tooth structure and health is largely determined by diet, especially three main factors:

  1. The presence of enough minerals in the diet.
  2. The presence of enough fat soluble vitamins (A, D, E and K) in the diet.
  3. How bio-available these nutrients are and how well the body is absorbing them. They found that this is largely influenced by the presence of Phytic Acid in the diet and how much sugar is consumed.

What is Phytic Acid?

Phytic acid is a molecule of phosphorus tightly bound with other molecules to form a type of phosphorus that is not easily absorbed by humans. 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.

Phytic acid is found in grains, nuts, seeds and legumes and in much smaller amounts in some fruits and vegetables. The body naturally converts phytic acid into phytates, which are un-absorbable and take calcium from the body. Those who consume high amounts of phytic acid will lose calcium and absorb other minerals at lower rates.

Modern growing practices, including the use of high phosphorus fertilizer, mean a higher phytic acid content in many foods. Seeds, nuts, bran, oatmeal, and soybeans are especially high in phytic acid, and these foods are present in abundance in modern diet.

Check out this article about phytic acid for a comprehensive list of phytic acid content in foods.

Phytic Acid’s Effect on Bone and Tooth Health

People who consume large amounts of phytic acid (most Americans) in the form of grains, seeds, nuts, and legumes have higher rates of tooth decay, mineral deficiencies and osteoporosis.

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.

Just as lack of Vitamin D and poor calcium absorption can cause malformation of the bones of the legs (as in the case of Rickets), it can cause the jawbone to form poorly, resulting in spacing problems for the teeth and braces for the child.

Sadly, the most commonly eaten diet in America these days is high in grains, sugars, and vegetable oils, and low in animal fats and fat soluble vitamins- the exact opposite of what the Drs. Mellanby found to be helpful for optimal bone health and the prevention of tooth decay.

The good news is that teeth (and bones) are able to heal themselves in a process called remineralization. Basically, specialized cells in the center of the tooth are able to regenerate dentin, the layer of tooth just under the enamel, and the enamel can then properly remineralize from the outside. This same process happens in bones when phytic acid is removed from the diet and minerals/fat soluble vitamins are added.

To prove this theory, the Drs. Mellanby did a study on children with existing cavities and reported their findings in the British Medical Journal. The children were put into three groups:

  • Group One: Regular diet plus oatmeal (which is high in phytic acid)
  • Group Two: Regular diet plus vitamin D
  • Group Three: Diet low in phytic acid plus vitamin D.

This is what they found:

grains cause cavities and bone loss

The group consuming phytic acid with no supplemental vitamin D continued to get cavities with little to no healing.

The group that just supplemented Vitamin D showed some healing, but also got some new cavities.

The group consuming no phytic acid and supplementing Vitamin D showed very few new cavities and actually had many existing cavities heal!

This article at Whole Health Source explains more.

When I brought this information up in health circles, it would usually spark a lot of debate and some strong comments from dentists or dental health professionals. Most would admit, after a time, that the enamel of teeth could regenerate but that once a cavity was through the dentin (the layer under the enamel), it was impossible for it to heal without dental intervention.

In my own life and in further reading, I’ve found that this isn’t the case either. As this article elaborates:

Fortunately, a decaying or broken tooth has the ability to heal itself. Pulp contains cells called odontoblasts, which form new dentin if the diet is good. Here’s what Dr. Edward Mellanby had to say about his wife’s research on the subject. This is taken from Nutrition and Disease:

Since the days of John Hunter it has been known that when the enamel and dentine are injured by attrition or caries, teeth do not remain passive but respond to the injury by producing a reaction of the odontoblasts in the dental pulp in an area generally corresponding to the damaged tissue and resulting in a laying down of what is known as secondary dentine. In 1922 M. Mellanby proceeded to investigate this phenomenon under varying nutritional conditions and found that she could control the secondary dentine laid down in the teeth of animals as a reaction to attrition both in quality and quantity, independently of the original structure of the tooth. Thus, when a diet of high calcifying qualities, ie., one rich in vitamin D, calcium and phosphorus was given to the dogs during the period of attrition, the new secondary dentine laid down was abundant and well formed whether the original structure of the teeth was good or bad. On the other hand, a diet rich in cereals and poor in vitamin D resulted in the production of secondary dentine either small in amount or poorly calcified, and this happened even if the primary dentine was well formed.

To be fair, most dentists probably don’t see many patients who are eating a specific diet to improve their oral health, and most of the studies and research they read is probably done on people eating a somewhat average diet (high in phytic acid and low in Vitamin D), so it is very logical that they wouldn’t think that teeth could heal. It certainly isn’t common, but with very specific supplements and a very careful nutritional program, it is certainly possible!

Halt and Reverse Tooth Decay?

To recap, the things that Drs. Mellanby and Dr. Price found to prevent and reverse tooth and bone problems are:

  1. The presence of enough minerals in the diet.
  2. The presence of enough fat soluble vitamins (A, D, E and K) in the diet.
  3. How bio-available these nutrients are and how well the body is absorbing them. They found that this is largely influenced by the presence of Phytic Acid in the diet.

What does this mean practically in the diet? It is not possible or necessary to eliminate Phytic acid from the diet. What should be considered is taking care to minimize the foods that contain the highest amounts.

Some preparations like soaking and fermenting can reduce the phytic acid content and should be practiced if the foods are going to be consumed, but in many cases, it is better to avoid these foods completely.

Nuts, for instance, have a high phytic acid content which can be greatly reduced by soaking the nuts in salt or lemon water overnight and then rinsing and dehydrating in the oven (the same can be done with beans). While this step is time consuming, it is feasible with things like nuts or beans, but much more intensive with wheat (which contains more phytic acid!)

Grains especially are better soaked, sprouted and fermented,  if consumed at all, but this process does not completely eliminate the other harmful properties of grains. Avoiding the most common food sources of phytic acid can also help:

Phytic Acid in common foods

You might notice that meats, eggs, vegetables, and healthy fats are not on this list of high phytic acid foods. As I’ve mentioned before, these foods contain higher levels of vitamins and minerals are are more nutrient dense anyway.

If foods high in phytic acid are going to be eaten, check out this article from the Weston A. Price Foundation on how to sprout, ferment, and soak them to make them less harmful.

There is also a great book called Cure Tooth Decay: Heal and Prevent Cavities with Nutrition by Rami Nagel that explains in great detail the connection between phytic acid and tooth/bone health and practical steps to reverse it.

How I Remineralized My Teeth

In early 2010, my regular dental check-up revealed that I had some soft spots and a lot of plaque on my teeth. I also had one “official” cavity, though it wasn’t bad, and while they suggested getting it filled soon, it wasn’t a huge rush. They did warn me that I had the beginning stages of gingivitis in several places and had a lot of plaque.(It took them about 30-40 minutes to scrape and clean my teeth, which I thought was normal) They took x-rays, so I have picture evidence of my teeth at this time.

I had every intention of getting the cavity filled and continuing with regular dentist appointments, but then life happened and I didn’t get around to scheduling an appointment for months. By the time I finally had time to schedule an appointment, I had seen some interesting info in books about the ability of teeth to heal, so I decided to hold off.

I did more research, read the book Cure Tooth Decay and read accounts of other people reversing dental damage, so I decided to give it a try. I took advice from all the research I had done and figured out a specific diet and supplement regimen that I was going to use to try to heal my teeth.

I followed the regimen for a few months, and noticed that my teeth were whiter and much less sensitive to cold. This was big news to me as I used to have such sensitive teeth that drinking too cold of a drink could literally almost bring me to tears. I also found out about this time that I was expecting a baby (p.s. this diet promotes fertility too!) and decided to continue on the regimen for the pregnancy, as all of the things I was doing were also supportive of healthy pregnancy.

It was fall of 2011 before I finally got around to making it back to the dentist (I know, I know… every six months…) and I didn’t mention a thing about the cavities and soft spots that needed to be fixed… and neither did the dentist!

It also only took them about 5 minutes to clean and scrape my teeth. I thought she was still checking them and she was done! The hygienist told me that my teeth and gums looked great, and asked if I had started using fluoride or fluoride toothpaste (my chart made it very clear that I was anti-fluoride). I told her no but that I had been trying to make sure I was taking better care of my teeth lately (very true!).

When the dentist checked my teeth, he didn’t mention any problem areas either and remarked that my gums looked great! On a random note, I heard him telling another patient that cutting back on the sugar and starches was a good idea since “without starches, cavities can not form, since they feed on sugar and starches.” Newfound respect for my dentist!

So what did I do?

Healthy Teeth from the inside out- supporting oral health with nutrition and supplements

Diet to Help Heal Cavities and Improve Oral Health

  1. I drastically cut foods that contained phytic acid. I already wasn’t eating grains or beans, but I also cut or limited nuts.
  2. Limited foods containing even natural sugars or starches– I limited fruit and even starchy vegetables like sweet potatoes and focused on mineral rich vegetables, bone broths, meats, and healthy fats.
  3. Ate a LOT of healthy fats. I added extra of coconut oil to my diet each day, and used only pastured, cultured butter.
  4. I made an effort to consume a lot of homemade bone broth for its added minerals. (If you’re short on time, I recommend buying your broth online from Kettle & Fire.

To recap: No grains, beans or nuts and limited fruits and starches. Lots of vegetables, protein, healthy fats and bone broth.

Supplements to Help Heal Cavities and Improve Oral Health

To help the body remineralize cavities, it is sometimes necessary to increase mineral levels with supplements. While diet alone might be enough, many foods are depleted of nutrients from being grown in nutrient depleted soil, so supplements help fill the gaps. These are the supplements I typically recommend for improved oral health and dental healing:

  • Fermented Cod Liver Oil and Butter Blend Green Pastures makes this as a Butter Oil/Fermented Cod Liver Oil blend. I prefer the combination in capsules or there is a liquid version (tastes terrible). This is one of the main supplements recommended by Dr. Price from his research. FCLO has become controversial recently, but it is the supplement I used to reverse my tooth problems and the one I would still use if I needed to do this again.
  • Vitamin D This was the other main supplement that Dr. Price and the Drs. Mellanby found was extremely supportive of dental healing. In the study they did, cavities healed even when diet wasn’t changed if Vitamin D was optimized and the best healing occurred when diet was optimized and Vitamin D was added.
  • Coconut Oil– I added a couple tablespoons of coconut oil to a smoothie or melted in tea each day. We get ours online here, but you can find it many places…. just look for organic, virgin and unrefined coconut oil. I also found that I could add healthy fats like coconut oil and butter to coffee or tea and used healthy fats like tallow, ghee and butter in cooking.
  • Other supplements– I also took Magnesium, Gelatin and Vitamin C daily, though these aren’t as vital to tooth healing.

Other Factors

Right now, my husband is trying the whole regimen to reverse a cavity he has, so I’ll keep you updated on his progress (hoping I might be able to get the x-rays from the dentist for proof when the cavity is gone… UPDATE: we are both cavity free and I’ve gotten a lot of emails from readers with cavity free teeth as well. Here is one of my favorites:

Hey Katie-

I just want to say thank you and share a healing success story thanks to your encouragement!

I am 30 and last year the dentist told me I had my first cavity – it was not going to heal, he said it was too far advanced and not possible. I told him I didn’t want to deal with it because I was diagnosed with stage 4 carcinoid cancer and had recently had surgery to cut out a tumor. The thought of cutting something else out of my body when I was working so hard to heal my body didn’t make sense to me. So I found your site, read your tips, made homemade remineralizing toothpaste, ate a lot of bone broth and good butter, cut down on phytic acid, etc.

I went back to the dentist 6 months later and he was shocked that the cavity was gone. He wanted me to tell him everything I had done. I felt so good!

What do you think? Would you try remineralizing your own teeth? Do you already do these things?

 

Did you know it's possible to remineralize teeth naturally? Teeth must be taken care of from the inside as well as the outside. This is how you do it.
