Can a Cavity Be Healed With Nutrition?

I’ve probably had 15-20 cavities filled in my 32 years.

Up until a few years ago, I always thought that cavities were just an annoying thing that happened, and there wasn’t a whole lot we could do to avoid getting at least a few. Lower your sugar intake, brush and floss well, and you’ll get less, right? When they do happen, simply get it drilled, and if you’re health conscious you can choose the white fillings over the silvery ones containing mercury. End of story.

Then I read the book Nutrition and Physical Degeneration by Dr. Weston Price about four years ago, and my thinking shifted entirely. I now believe 100% that teeth can be strengthened and remain cavity free through real food and traditional nutrition. Not only that, but even once a cavity has formed, it can be remineralized and filled back in again, quite possibly requiring zero dental work.

I know this is a highly controversial issue. Would it surprise you to know that the most viewed (and most ferociously challenged) post on this entire website is Rethinking Oral Health Care: A Homemade Toothpaste Recipe for Tooth Remineralization? Even the mere idea that teeth can be remineralized through any method brings about loud protest from the dental health professionals.

To some extent, I get it. It’s so far-fetched compared to what we’re learned about oral health. Sure, many of us believe that eating differently can help us lose weight, have more energy, manage diseases like diabetes, reduce behavior problems in children, even help to balance hormones. But heal and re-fill areas of decay that have already formed in our teeth? It’s crazy, I know.

Our family has had one small experience with this, and below I will share more stories with you. My daughter Abbie had a small-medium sized cavity that the dentist wanted to fill, but as we have no dental insurance, we postponed it for a little while since it wasn’t bothering her. I worried that in the interim months (it was about 3-4 months) it would get much worse.

To my complete surprise, when she went back in to have it looked at, the dentist said it was only a pinprick and didn’t even need drilling. The main thing that had changed in those months was that we significantly increased our consumption of grass-fed raw milk and butter (and this makes sense if you read Dr. Price’s book or any of the literature out there on the dietary changes that will heal decay).

One mom’s story of how nutrition healed her daughter’s teeth

The story below comes from my dear friend, Renee. As you read it, you’ll quickly see how similar we are and you’ll understand why we like to call each other to discuss the canning jars we scored at a thrift store, which flavor of cod liver oil is working out best for our kids, and how we just made a really fantastic new batch of homemade deodorant.

So when I asked her to write out this story for the blog, she didn’t bat an eyelash because healing cavities is another one of the “weird” things we like to talk about and she was thrilled to share it with you…

After coming home from Africa a year and a half ago, we dutifully began making rounds as a family to doctors and dentists. Missionaries always take any chance in their home country to catch up on needed work while in a familiar setting. We were no exception.

Reese, who had just turned seven, went in for a dental check. Her teeth looked good and felt great, but surprisingly we were told she had eight cavities that needed filling! We were very surprised and suspicious, to say the least. I did not have peace at all about the diagnosis and with support from my husband, I began the journey of researching teeth.

I began by praying a lot, not sure where to start but knowing that I needed to find out why and how cavities were invading her mouth. We moved shortly after the initial check up and x-ray exam and began looking for another dentist in our new area. I didn’t want to ignore the cavities and cause them to get worse, but at the same time I was feeling very strongly that I needed a dentist I could trust. It was taking more time that I realized.

I tried several but came away frustrated at how they pushed antibiotics and root canals for a problem that wasn’t even proven to be there. While I continued to pray for the right dentist to address Reese’s problem, the Lord began to bring things to me.

I had been learning lots about health and natural medicine for just about as long as I had been alive. My mom taught me many things and now as a parent, I couldn’t soak up enough information. I was eager to help my kids have the best health possible. I really believe the Lord was leading me in my study. Books came to my attention that I hadn’t read before.

I became fascinated and ecstatic after reading Weston Price and his ‘Nutrition and Physical Degeneration‘, and then Ramiel Nagel’s ‘Cure Tooth Decay‘. Everything began to come together after I read that book. I had researched and tried raw un-cooking for a time, was a vegetarian for a time, learned about the foods recommended for your blood type, the Makers Diet, the PH Miracle, and again and again it came back to simple things. Stay away from refined foods and sugar, put in plenty of good fats, raw foods and soaked grains.

We finally did find a good holistic dentist but it was about the time I began to come up with a plan to reverse Reese’s tooth decay. I asked my husband to give me 3 months to work intensively with Reese.

We did the best we could. We took away all forms of sweetness, even natural things like honey and fruit. We took out all refined foods and stuck to lots of vegetables and soaked grains. We ate tons of Kerrygold butter and raw cheese. I gave her a double dose of fermented cod liver oil every morning with her raw milk. We also began using clay toothpaste.

She was such a good sport about the whole thing! Of course there were days that weren’t perfect but on the whole we were very diligent.

We finally made an appointment for her at the dentist. They cleaned and x-rayed her teeth and found NO cavities. There is a tooth that had actually started to decay on the back side but got hard again. They were very encouraging and I was completely amazed. I had hoped that at the least one or two would be completely gone, but to have every one healed, I just praised God and stood in awe!

I really believe that God led me to study and healed Reese’s teeth. He is so good and he sees how much we want to care for our children and provide the very best for them. Call out for wisdom; His word promises that He will answer!

Green Pasture Cod Liver Oil/Butter Oil— This is the cod liver oil that our family takes. The kids take the chocolate cream variety, and my husband and I take the capsules (well, sometimes I take the cream instead). You can purchase it through Amazon, although the way to get the best prices is to find other friends or family to go in on a large order with you and purchase at least 6 or 12 bottles to get a better discount directly through the Green Pasture website.

If you have a story to share about how you used nutrition to heal teeth, we would LOVE to hear it!

  1. I suggested checking out tooth remineralization to a church friend. Her daughter had a visible cavity and tooth pain and expressed concern about simply getting it filled. So she embarked on the Dentist Challenge, recording what she used and taking photos of their progress. It is day 49, and there is very visible improvement where the cavity was. I am elated! She primarily used Vitamin D with cod liver oil, coconut oil, and/or butter oil (clarified butter) and brushing with a homemade baking soda/calcium bentonite/coconut oil toothpaste. Read the blog posts and see the photos for yourself!

  2. Cavity can be definitely healed by a nutritious diet..but if it is preferable to visit a dentist if the cavity persists for a longer time..

  3. Hi, I recently have spotted a small-medium cavity in one of my front top teeth, I decided to give healing a try and I went on a 100% raw diet, my current diet about 55% vegetables and 35% fruit and 10% nuts.
    I really have no idea where to get raw milk as I live in an urban area, and I’m anxious that the cavity might get worse, I don’t know if I should go to a dentist.
    Any advice?

  4. Princess says:

    I am so interested in doing this for my cavities. I’m having to go to a free dental clinic because I don’t currently have insurance and my tooth hurts.
    I want to know which foods I should eat? Will it only work if I cut out fruits and honey and everything else that’s naturally sweet? If so, what do I replace those foods with?
    Thanks so much!

  5. Jocie M says:

    This is very intriguing to me. I have been studying Weston Price, but- any recommendations for children who are milk protein intolerant? I think I will try the black walnut tincture suggestion above 1st, along with implementing WAP the best we can. The decay has stopped, but it is very visible (very front top tooth) and will be obvious if it starts to heal.

    We have had a few dentists want to get at it, one suggesting it was urgent, even though the decay has stayed the same for years and she is not in pain. (It is from when she was 1 and I was nursing her through the night without brushing her teeth. Which is what I did with all of our other children, but this is the first time we were on well water (no fluoride).

  6. Deborah says:

    So much wonderful feedback. I am also intrigued to know how Celiac and grains play a role in dentistry. I know that growing up with undiagnosed Celiac, I had very limited tooth enamel and plenty of cavities. My children are also Celiac, but eating grain free and have beautiful healthy teeth. I’ve been using straight bentonite clay and magnesium powder on my toothbrush for a few weeks now, hoping to heal years of dental and gum damage. Nothing ventured, nothing gained, right?

  7. Amazing story Stephanie. There’s some real good evidence here and some truth to this. I am going to dig deeper into this. Thanks so much for sharing!


  8. Carl Stone says:

    I did not even think about this. I had to have Periodontal surgery a couple of years ago.. I asked the dental surgeon what if anything that could be done to help with the surgery. He really had no help. So I started doing online research, and with a limited medical background started brushing about 6 weeks before the surgery with liquid magnesium/calcium supplements. My overall oral health increase, my teeth began to become whiter and after the surgery I was healed in about 2 weeks, which the surgeon was totally surprised at, he even asked what I had done and when I explained he could not believe that it worked that well. Thanks for letting me tell my story and I loved the article..

  9. I think it depends on how bad the cavity is. There will be times when only a dentist can help.

  10. Renee Kling says:

    I read all this with great interest , amazed, but sorry not to live in USA ……..I will try to order the Earthpaste here in Sweden and give it a try ! Thanks to you all for your comments !

  11. I love this info on cavities healing up. Sergei Boutenko has a great story of his own fillings popping out after his family started him on all raw foods at age 9 or so. He asked his Mom and she said, ‘let’s wait and see what happens’. And what did happen was that his cavities all filled in with new enamel and I believe he has never had another cavity (he is now in his twenties, teaching health See the above story in Raw Family, a small book (extremely readable and fascinating) which can be found at

  12. This isn’t exactly nutrition, but my son’s dentist recommended a xylitol paste to put on his teeth that is supposed to help reverse cavities. Have you heard of this? If so, any opinions?


    • Renee K. says:

      Yes, xylitol has been shown to harden teeth. What I’ve heard is that it’s not the best in your body, but on your body (teeth). We have Earthpaste and a Xylitol toothpaste in our cupboard at all times since my husband doesn’t really like the clay toothpaste.

  13. Thanks so much for gathering all these links and resources in one place. I look forward to referring people to this post for more details on the nutrition-dental connection!

  14. Renee,
    I agree with everything you have said in your story about praying to God and, of course, about limiting your daughter’s sugar intake, but I hope you’ll rethink the fact that you’re giving her cod liver oil daily. My husband’s grandmother was a firm believer in taking a daily dose cod liver oil, and she died of cirrhosis of the liver. While she was very healthy most of her life and lived to be 92 years old, she suffered terribly at the end. This was a woman who seldom drank. She would have a glass of wine once in awhile. What happened to her was that she oviously had consumed too much Vitamin A during her lifetime by taking the cod liver oil daily and damaged her liver. That’s wonderful that you’re improving your dental health, but I hope you’ll look at the whole picture, and check with your daughter’s doctor to be sure that her daily intake of cod liver oil is not going to harm her in any other way over time.
