Book Review: Cure Tooth Decay by Ramiel Nagel

Tooth decay has become an accepted norm in our culture. Sure, we fluoridate our water, scrub our teeth with plastic bristles and dutifully have our teeth scraped with metal objects a couple times every year. But for all our effort, tooth decay remains an ever present part of our lives. While modern dentistry preaches prevention, the underlying policy is to drill and fill the imperfections in our teeth. Above all, the word “cure” is never used in conjunction with subjects like cavities, gingivitis and other dental woes.

Until now. Ramiel Nagel takes the daring leap from drilling to curing in his book Cure Tooth Decay. To be perfectly honest, before hearing about this book I never even considered the idea that tooth decay could be reversed. I was so swamped by cultural bias that I assumed cavities could only be prevented by brushing, flossing, and staying away from sweets. And if that didn’t work (as it often doesn’t) then it was time to drill those poor teeth to oblivion. But according to Rami, this system of dental care fails at every level:
“Modern dentistry is a profound failure. The enormity of suffering and disease caused by dentistry is so massive that it is beyond comprehension.”
“High speed drilling creates high friction and raises the temperature of the tooth nerve, causing irreversible nerve damage in 60% of cases.”
Nagel goes into depth about why and how modern dentistry has failed us. For not only are their treatments ineffective (some might even call them cruel), but the focus is never on the right thing: preventing and healing tooth decay. He also addresses several of the common myths about tooth decay (such as food on teeth causing cavities).

A Comprehensive Guide to Tooth Decay

I was floored by the amount of information contained in Cure Tooth Decay. I honestly did not expect to learn so much about what makes teeth healthy and why tooth decay happens. I was also surprised how little I really knew about dental health. Reading about the process of how teeth remineralize was absolutely fascinating.

For years, dentists have been treating teeth as if they are separate from the rest of the body. And perhaps this is the greatest mistake concerning the health of our teeth and gums.

Nutrient Density and Tooth Decay

As we know from the work of Weston A. Price (detailed in Nutrition and Physical Degeneration), tooth decay was far less rampant in traditional cultures who consumed their ancestral diet than it was in modern society. Price took the information he gathered from traveling the world and applied it to his patients when he got home.
It’s interesting to note that Price did not put his patients on traditional diet. Instead, he applied the principles of traditional diets by adding a few key nutrient dense foods to their diets. This had a marvelous effect on their general health as well as the health of their teeth.
In Cure Tooth Decay, Nagel outlines these same principles and gives specific tips for supplying the body with the nutrients it needs to remineralize teeth. Some of these key nutrients include vitamin A, vitamin D, vitamin K2 (what Price refers to as Activator X), and important minerals like calcium, phosphorous, and trace minerals as well.
Nagel suggests specific foods that can help supply these nutrients (grass-fed dairy, pastured eggs, bone broth, liver and seafood top the list, of course) and also outlines which foods may be causing problems with nutrient absorption. Following in Price’s footsteps, he emphasizes the benefits of supplementing with high quality cod liver oil and butter oil.
“If you have tooth decay, you are presumably deficient in vitamins A and D.”

Metabolic Function and Tooth Decay

“A malfunctioning thyroid gland also plays a role in producing tooth decay and gum disease because the thyroid plays a role in maintaining blood calcium levels.”
I was impressed when Nagel brought metabolic function into the picture. He touched on how overall metabolic health (such as thyroid and pituitary function) can affect how the body regulates where minerals are deposited. A poor metabolism may very well lead to tooth decay and gum disease.

Obey Nature, Heal Tooth Decay

“All you need to do to heal cavities is understand Nature’s rules for health, and then follow them. When you follow these rules, the built-in ability for your teeth to heal will take over.”

Nagel goes into great detail in Cure Tooth Decay about all of the ways our diet can affect the health of our teeth and gums. He offers plenty of practical and specific directions for healing tooth decay.

But he does manage to avoid sounding preachy and rigid in his suggestions. While he admits that those with extensive tooth damage will probably need to follow the stricter approach, he fully embraces the idea that you should do what works and what feels right for you as an individual. He also offers meal ideas and suggestions for eating out. He even provides details for a “One-Amazing-Meal-A-Day” protocol that can be really helpful for those need a stepping stone into the world of nourishing food.

Final Thoughts on Cure Tooth Decay

There is honestly so much good information packed in this book that it’s impossible for me to even come close to summarizing it in a blog post. I’m pretty sure that tomorrow I’m going to think of a hundred things I forgot to mention. Here’s some more topics Nagel covers in Cure Tooth Decay:

  • Weston A. Price’s original tooth decay curing protocol
  • How teeth remineralize
  • Blood sugar regulation and tooth decay
  • Why healthy gums matter (and how to heal your gums)
  • What causes plaque and calculus deposits
  • Toxicity of mercury fillings and fluoride treatments
  • Safe filling materials
  • How to find a good dentist
  • How your dental palate affects your health
  • Alternatives to braces
  • Safe tooth whitening
  • Healing your children’s teeth (from infants to older children)

  1. This could not have been more timely for me. I’m dealing with a gum infection right now that appears to have spread to my eyes! Yikes! I have a dentist appointment tomorrow and an eye doctor appointment next week. I’m sure I’ll have to take antibiotics but I am definitely going to check out Nagel’s book for future reference. Thank you! I learn so much from your blog.

  2. I love looking up info about vitamins and minerals and other assorted related stuff. Found out something interesting about vitamin K2. It is essential in the production of the substance osteocalcin in the body. Osteocalcin is important in the strengthening of bones and dentin. Also, it is metabolically active. It stimulates the production of a chemical called adiponectin by the fat cells (everybody has those, fat or slender), which then increases insulin sensitivity all over the body. If blood sugar regulation influences rate of tooth decay, that’s two ways vitamin K2 helps prevent you losing your teeth. And I wouldn’t be surprised if there are more.

    They’re also looking into the possibility (maybe more like probability) that vitamin A plays some specific roles in metabolism and blood sugar regulation too. While most people are not deficient enough in A to lose their eyesight, I suspect most of us are walking around with subclinical deficiency. I know I have, probably several times in my life.

    I think the only reason I haven’t had more trouble with tooth decay is I never tried to go strict lowfat in my diet. Oh, and also, I have never completely given up cheese except for a short stretch in 2005 when I experimented with going vegan. (Never again!)

    • That’s really interesting, Dana. I’m amazed at how much fat soluble vitamins impact our health at so many levels. Maybe one day dentists with be handing out samples of butter oil along with that free toothbrush. Well, a girl can hope… 😉

      • This is a bit off topic but the fat comment reminded me of the absorption of D3. A lot of supplemental D3 products are garbage because they are not fat based. People are hoofing down these D3 supplements and wondering why their D levels are not rising.

        Soooo… anyone reading this… if you’re planning on supplementing D3 look for quality supplements that are fat based… like olive oil etc. Avoid the cheap powdered garbage out there… well… unless you think your toilet water is D deficient. 😀

  3. Interesting. I’ve heard about this book before but I never read it. It sounds like a book I should get. Thanks.

  4. I think that sugar rots your teeth from the inside out: leaching minerals from your body that would otherwise go to the health of your teeth and gums. That is why, in my opinion, brushing and flossing are ineffective in fighting/keeping cavities at bay; because, when you think about it cavities don’t form from the outside, the holes start from the inside. You can brush and floss your teeth until the cows come home — if you are eating too much mineral-leeching sugar (in all its forms) and not getting enough good saturated fat — all that brushing and flossing will be for naught.

    Also, when I had a gum problem (a little over a month ago) from some past dental work that, in the long run, has turned out to be ineffective, I tried oil pulling with coconut oil and a few drops of tincture of cloves. It took a little over a week to heal the infection (daily oil pulling for 20-plus minutes a session), thus saving me several hundreds (perhaps, thousands!) of dollars in dental fees.

  5. Teeth don’t rot from the inside out. You can see them on X-rays going from the enamel (outside), into the dentin (middle), and spreading to the pulp (inside) over time. They don’t go from the outside in.

    Remineralization is actually very well accepted and promoted by dentists, actually using components from milk (MI paste), (and also, of course, Fluoride) but not after a certain point. Once you “reach the point of no return” with a large cavitation in the tooth, you can’t re-build the shape of the tooth and you may develop functional problems (TMJ problems and possible bone loss) that will come as a result of your teeth not fitting together correctly anymore and banging into each other.

    The interaction of gum disease with the whole body has been well-documented and is well accepted by the mainstream dental community to interact systemically (a discipline called Periodontal Medicine). There is lots of interest in this field right now. Some very well known interactions include cardiovascular disease, renal disease, pre-term low birth weight, pulmonary disease and diabetes.

    Many dentists work very hard and devote their life to prevention, talking about improving diet to patients and teaching this to dental students in schools, however, if patients don’t listen and continue to make unhealthy lifestyle choices, the advice often falls on deaf ears. To this end, the profession should be doing more for public education, for sure. However, as long as there are people making poor diet and health choices who choose not to listen to nutritional advice, there will still be the need to teach how to drill and fill and it is probably the right solution for some people to prevent fatal infection (remember the little boy who died last year from an untreated cavity?).

    I just wanted to point out that a lot of this is actually more mainstream and more well accepted that you may think!!

    • Meg, great points. I think the dental community is really coming around to these ideas. There are definitely some excellent dentists out there. The problem is when people have had experiences with dentists that don’t advocate these principles and they don’t realize there are other options. I was definitely one of those people until I read this book. I had never been to a dentist who even hinted at the fact that cavities can be healed. If I had known this, it would have saved myself and my family a great deal of unnecessary pain.

  6. This was exactly the review I needed to urge me to purchase this book…it’s been on my Amazon Wishlist for several months. Time to buy and apply. :)

  7. For several years now we’ve been offering a product called Tooth Chips – Soap for Teeth.  They were birthed when I had such tooth sensitivity that I couldn’t stand it any more.  One of the main things I tell our customers is that you HAVE to eat right in order for the saliva to be healthy so it can nourish your teeth and gums.  People don’t understand that a healthy diet is a cure all for so many of the medical problems out there today.   Keep meals simple and stay away from boxed and prepared foods!

  8. I am
    successful on healing the decay of my molar tooth. I don’t know what I did
    to be able to heal it completely but what I did is just to brush my teeth every
    after meal. I want that book so I would know what other effective ways to cure
    tooth decay.


  9. I didn’t know that we can cure tooth decay. I want to buy
    this book to have further knowledge about it. This can lessen my dental
    treatment expenses too, so I think that this is a must read book.
