DIY All-Natural Whitening + Remineralizing Toothpaste

I want to immediately address the elephant in the room before we go any further…

YES, this toothpaste is brown. And NO, it is not the loveliest looking.

But hey, we all know not to judge a book by its cover!

And those perfectly white toothpastes that you are comparing it to may look pretty, but they’re chock-full-o’-nasties.

This DIY toothpaste on the other hand contains ingredients that help both naturally whiten and remineralize teeth while not contributing to your body burden. What more could we really ask for?

DIY All-Natural Whitening + Remineralizing Toothpaste


Makes roughly 4 oz of toothpaste

You’ll also need a small jar or squeezable silicone tube to store your toothpaste.


  1. In a double boiler, melt the 4 tbs of coconut oil. Or… if you are like me and don’t have a double boiler, you can simply stick a jar in a pot filled with shallow water, set the burner on medium-low, and put the coconut oil in the jar for it to melt (be sure not to get water in the jar).
  2. After the coconut oil is melted, remove the jar from the pot, wipe the water off the bottom, and set it on the counter.
  3. Next, add all of the other ingredients using a plastic or wooden spoon since a metal spoon will negate the effects of the bentonite clay.
  4. Stir everything together. The consistency will be runny but uniform, but it will harden into a thicker paste once it cools.
  5. So pop the jar into the fridge to set, stirring every five minutes to keep everything uniform.
  6. After about 15 minutes, you should see it start to thicken.

And there you have it! Your very own all-natural whitening & remineralizing toothpaste!

Let’s take a closer look at the ingredients:

Coconut oil

Coconut oil acts as the base for the toothpaste, keeping everything together. More importantly, the lauric acid in coconut oil is a natural antibacterial.

Sesame oil

Sesame oil also acts as the base for the toothpaste, helping to soften the paste since coconut oil can get pretty hard. This was important to me since I wanted to be able to squeeze my toothpaste rather than keep it in a jar. (If you don’t care about squeezability, you can simply replace the sesame oil with more coconut oil). Sesame oil is traditionally used for oil pulling (a practice I will cover more soon!) and also has antibacterial properties.

Bentonite clay

Bentonite clay is a staple in my house. This “healing clay” binds to and draws out impurities, helping to not only detox the mouth but also whiten teeth by removing stains. Bentonite clay is also high in calcium, magnesium, and silica which help remineralize teeth.

Calcium magnesium powder

Calcium and magnesium are critical for bone and teeth health. Calcium is obvious here, and magnesium is critical for calcium to be properly absorbed. This calcium magnesium powder contains the optimal balance of both.

Baking soda

Baking soda is alkaline, helps clean teeth and remove stains, and wards off bacteria.

Essential oils

After doing the research, I consider peppermint, cinnamon, spearmint, clove, and myrrh essential oils to be the top five essential oils for healthy teeth and gums (though I’m sure there are certainly more!).

Trace minerals

Trace minerals help restore and remineralize tooth enamel.

[Side note: I know this seems like a TON of ingredients but most of us already have coconut oil, sesame oil, and baking soda in our kitchens. Most also likely have at least peppermint EO, which can be used alone in the recipe if you’d like. If you don’t have bentonite clay, I suggest you get some ASAP since it’s so multipurpose and amazing (check out how I use it every day, week, and month). Trace minerals and calcium magnesium powder are both fantastic supplements so a great investment as well.]

When you use it for the first time…

The consistency and taste are certainly not what you are used to. I use more of this toothpaste than I would with a “normal” store-bought paste since it does not foam, probably about double. The coconut oil will melt rather quickly in your mouth since it has a melting point of 76º turning the paste into a thick liquid. Also it is definitely salty! I don’t mind, but you can add liquid stevia or xylitol if it does bother you (or if you are trying to get your kids to use it!).

P.S. Like my toothbrush?

It’s bamboo! As you know, I kinda sorta HATE plastic. And we sure do use a lot of toothbrushes, which (along with their plastic packaging) just end up in landfills.

These toothbrushes have bamboo handles and the packaging is completely biodegradable. In other words, they’re awesome.

  1. Amy!bentonite is generally considered inert, i would find it strange that it would cause gum, and nerve /pulp inflamation.It is very unlikely that bentonite is cleaving mercuary from your fillings, and re-depositing in your mouth off the top of my head two causes i can think of are… 1 the bentonite is leeching minerals away from places where cavities are begining to form, causing exposure of the pulp, or 2 morw likely, the bentonite you used, is contaminated. There is really no regulation on “natural” suppliments such as this, for all you know the bentonite you used,could contain trace elements such as arsenic, or a some radioisotope of iodine;). Besides mercuary is a large molecule, i doubt it would be able to penetrateflesh, and tooth that quickly,especially if it is bonded with bentonite!… Unless you ingested it.if i were to use bentonite, i would brush with it seperately, first, then use the re mineralising mix, as im sure the bentonite would otherwise ABsorb most of the cal/mag

  2. I have a question about the bentonite clay. You said to not use a metal spoon since it negates the effects of the clay. What if you are someone with a mouth full of fillings? (I know, I know…but can’t afford to take out mercury and replace – and my naturally acidic saliva is why I have so many mouth problems and have been counter-balancing to a greater success with xylitol and baking soda) Won’t the bentonite clay not be good to use in a situation like that? I used a friends bentonite clay once and my mouth was in pain and burned for a couple of days and all my fillings hurt. I stopped using immediately and tried googling but metal and bentonite clay turns up a million hits on the positives of using this clay to extract toxins and I do not have time to sort through in order to find the answer to this specific question on how it reacts to fillings. Was hoping you might know.

  3. XYLATOL!!!its crazy antimicoboal eyrythratol may be even better tho?

    ARGANINE!!!! “Colgate pro argine” Dialates tube thingys in tooth walls (via nitrix oxide), increasing cal/mag delivery

    FRINGE SCIENCE/ need further studies:

    MSM: confirmed, increases tissue permeability slightly, anti inflammatory. Possible Ca/Mg delivery system. Ancedotal accounts of dental efficacy, especially gum health

    DIMETHYL SULPHOXIDE:similar to MSM,dubbed the needleless injection, due to efficacy as trans dermal delivery system.also dubbed as a universal solvent, as it can disolve a bunch of organic and inorganic chemicals. Insanely anti inflamitory
    dental info….ZERO
    Possible side effects: best guess….It may dump a bunch of insoluble calcium into your bloodstream, it may disolve /liberate mercuary in fillings?

    DONT OVERLOOK CAL MAG INGESTION:calcium magnesium AMINO ACID CHELATE(AAC) with: boron,vitiman k2 and D3(WITH FAT).

  4. Yes, coconut oil CAN clog your drains. It has a melting temp of 72? degrees F? (Or 73, 75? Something like that)

    IT IS BEST to spit into a paper towel.

  5. What is the shelf life of the toothpaste? In other words, how long does the 4oz last? And I’m thinking of buying the ingredients that are listed on the recipe, 8oz of bentonite clay, 8oz of calcium/magnesium powder, and 8oz of trace minerals. On amazon the total is about $35 (I’m also going to get a four pack of bamboo toothbrushes but that is not included in the $35) How long do you think these ingredients will last? How many 4oz toothpastes can I make, roughly? Does anyone have a guesstimation? Thanks!

  6. I made the tooth paste today … It set up when I put it in the refrigerator … However no it is no longer set up… I didn’t have a squeeze tube so I just have it in a mason jar… Any suggestions?

  7. What are your thoughts on the amount of lead in the bentonite clay? I read that it has less than most produce, but I’m still terrified to use it especially since I’m still breastfeeding my 17 month old son.

  8. Is there another option (besides more coconut oil) to replace the sesame oil to make the toothpaste more squeezable? Or is sesame oil particularly beneficial? I have almond, grape seed and olive oil on hand.

  9. Hello! I have just found your site and loving it! I am learning the more natural way of things and was wondering if using the bentonite clay does anything to fillings? I have a couple amalgam fillings from when I was little and want to replace when I can but I didn’t know if they will ruin them?

  10. It’s probably the calcium-magnesium powder. Did you make it and then use it immediately? Or did you make a batch, then use it later? If you do the later, the bubbling should all be gone.

  11. This had an eppervesant effect when I used it to brush, felt bubbly and a little hot?? Followed the directions added cinnamon and cinnamon essential oil, 5 drops and and 5 peppermint. Just checking, I’m twisted because if I just bought a toothpaste with these ingredients I wouldn’t question it, but since I made it I always feel like I’m going poison the water hole.

  12. I can’t consume Sesame oil, but would like something more squeezable than coconut oil. What do you think about Almond oil?

  13. The calcium magnesium from your link to amazon might be from a genetically modified product. I haven’t done any research but one of the comments suggest that.

  14. I notice the magnesium calcium powder is a combination of magnesium citrate and calcium citrate, Maybe I’m just ignorant, but wouldn’t it be bad to put something citric on your teeth?? I’ve been advised to drink lemon juice with a straw to keep the citric acid off my teeth. Is citrate any different?

  15. I just read that coconut oil contains 50% Lauric acid – will using it in toothpaste damage tooth enamel?
