Homemade Remineralizing Toothpaste With Bentonite Clay

I’ve been making my own remineralizing toothpaste with bentonite clay for my family for years.

And yes, since using this my cavities have not progressed and I’ve had positive feedback from my last dental check-up so it must work.

My health and wellness journey started with a cavity and a question.

Can you reverse a cavity?

This led to years of learning about nutrition and its effects on the body.

So, can cavities be prevented? Are they a sign of a nutritional deficiency?

The short answer is yes.

But what about conventional toothpaste? Is it healthy?

Are there harmful ingredients in conventional toothpaste?

Conventional toothpaste contains some harmful ingredients that may cause toxicity. These include fluoride, emulsifiers like carrageenan, Sodium Laurel Sulphate, and artificial sweeteners like aspartame.

Maintaining good oral hygiene is paramount to healthy teeth and gums but it’s not the whole story and one of the biggest problems with conventional toothpaste is fluoride.

According to the Journal of American Dental Association, ingesting fluoride in children under the age of 6 can lead to fluorosis. This is the condition where the appearance of white lines on the teeth developing under the gums.

This review shows that systemic intake of fluoride through municipality water has been shown to be neurotoxic to developing children but what’s interesting is that the body can absorb whatever is put into the mouth as it can enter the bloodstream.

This could mean that fluoridated toothpaste may not be safe for children at all.

I grew up squeezing brightly coloured glitter toothpaste (also known as kids’ toothpaste) thinking it was fun. Although I always had a thought in the back of my head wondering why toothpaste is sweet.

Sugar and sweets feed the type of bacteria that don’t promote health in the body and toothpaste contains sugar.

The mouth is one of the most concentrated places of microbes in the body.

This means that if there are cavities or gum disease or any other type of infection, bad bacteria have outgrown the good and key nutrients are missing from the diet to fix the damage.

The benefits of making your own remineralizing toothpaste with bentonite clay

Other harmful ingredients in conventional toothpaste is the added ingredients like:

  1. Anti-caking agents
  2. Aluminum oxide
  3. Artificial sweeteners

that don’t contribute to a healthy mouth and can even cause toxicity and as if these weren’t already bad there’s one more ingredient that’s even worse: sodium lauryl sulphate (or SLS).

SLS is a surfactant that you can find in almost all cosmetics and personal care products like soap, toothpaste, and shampoo.

Surfactants can build up in the body and cause toxicity, especially when you put it in your mouth. When the body accumulates too many toxins, the liver becomes burdened and might have trouble detoxing all of those toxins out.

So, one really simple way to relieve the body of toxins and the build-up of toxins is to use personal care products that have natural ingredients.

What is Bentonite Clay?

Bentonite clay is versatile and 100% natural. It is beautiful to touch, soft, and filled with naturally occurring minerals.

This clay is formed as a result of volcanic eruptions. The first clay was actually discovered at Fort Benton in Wyoming. It is an absorbent consisting mainly of vital minerals like calcium or sodium (depending on the type), magnesium, and iron.

People use this clay as a base for soaps, for natural skincare, and even take it as a drink for detoxification purposes.

Other important ingredients

Salt– I use finely ground Himalayan salt here because salt is naturally anti-bacterial and can fight infection.

Coconut oil– naturally anti-bacterial and promotes a healthy microbiome in the mouth. I’ve had success in reducing plaque in my mouth just by oil pulling with coconut oil.

Essential oils– we’re using cinnamon, frankincense and peppermint essential oils. All of these have shown to have positive effects on the health of teeth and gums.
