Dentist’s comments about my home-made teethpaste / Prophylactic self-isolation series. Day 316th.

Drop intro

It was the very beginning of Prophylactic self-isolation series when I made my teethpaste (yes, for teeth, not for one tooth:)) which I still use! The ingredients and method are listed below:

Home-made teethpaste


  • Diatomite powder/ diatomaceous earth, food grade, 50 g
  • Soda/sodium bicarbonate (purified, aluminum-feee, food grade), 1 tsp
  • Salt (milled from crystalline salt into a powder), 1/2 tsp
  • Sage leaves (dried and milled into a powder), 1 tsp
  • Water (purified), 120 ml (or 120 g, it is the same amount)
  • Guar gum, 1/8 tsp
  • Coconut oil, 1 Tbsp
  • Cedar essential oil, 3-5 drops

The method

The method of making this teethpaste, as well as characteristics of its ingredients are described in the previous post:

Prophylactic self-isolation for teethpaste preparation. Day 61st.

These days I had a luck to meet the dentist Tomasz S. who agreed to give his professional comments on the composition of my teethpaste. The toothpaste made by a pharmacist got a review by a dentist. Great duet, isn’t it?

So, how does the home-made toothpaste look like from the perspective of a dentist? Here below are the questions and comments of the dentist and my answers.

Dentist’s comments

Comment 1:

How long this paste could be used after preparation? 1week? 1 month? Is it possible to add any natural preservative to extend the validity period?

Pharmacist’s answer: The paste could be used within a month while a small tube of the paste (50 ml) is in the bathroom and left amount is in glass jar in a refrigerator. Natural preservatives in a form of essential oil are already in the formulation, however, its amount is not enough to keep the paste for more than one month.

Comment 2:

This paste is perfect for persons like you – with very good oral hygiene. Unfortunately, many people have worse hygiene and for them, any cariostatic agent e.g. xylitol could be very beneficial. Do you see any possibility to add a natural cariostatic agent to your paste?

Pharmacist’s answer: Xylitol could be added, it is a great idea! I would prefer to add xylitol of natural origin, such as from birch wood.

Comment 3:

The use of sage is perfect for the gums! Maybe add also chamomile?

Pharmacist’s answer: Sage leaves when milled form a kind of fluffy substance, while powdered chamomile would be just microparticles of chamomile. To avoid abrasiveness effect, I would prefer to stay with sage.

However, need to say that sage could dye because of natural pigments, and should be added to the recipe time to time, lets say, each second month, not constantly.

Comment 4:

The color of the paste might not be so attractive for some people, is this possible to change it with any natural colorant? Maybe beetroot extract?

Pharmacist’s answer: The color should stay the same. This “unattractive” color makes difference and tells the user that absolutely different type of toothpaste product is in his/her hands. I would not change it just on purpose of this important visual message.

Comment 5:

Is it possible to determine the size of diatomite grains? Or to buy it in a certain shape? This is important to estimate abrasiveness (RDA) of any toothpaste

Pharmacist’s answer: Diatomite grains are not abrasive and could be used for cleaning the teeth.

Final thoughts

This exclusive evaluation of the quality of the home-made toothpaste brought number of thoughts where I can improve the formula, and also emphasized its strong sides.

In my further experiments, I think to add xylitol, and there are a few thoughts to change the base (diatomit) with another ingredient. However, the existing teethpaste we still use every day for more than half a year now!

Struggling with coconut oil

Coconut oil-based toothpastes are runny

I recently improved the formula to make the consistency of teethpaste not runny.

You probably know that coconut oil melts at room temperature. Especially in warm periods of the year, coconut oil in a composition of home-made toothpaste makes the consistency a bit runny.

This could be easily corrected by replacing coconut oil with the similar ingredient.

Coconut butter to improve the formula

There is a similar coconut product which melting temperature is a bit higher than the melting temperature of a coconut oil.

By using this specific ingredient one could enjoy a proper usage of home-made toothpaste when squeezing it out of the tube.

Other names of coconut butter (synonyms)

Coconut flesh, coconut manna, coconut mousse

What is coconut butter?

Coconut butter is made of pure coconut flesh (raw coconut flakes). It is rich in lauric acid, calcium and magnesium; fats are mainly medium chain Triglycerides (MCTs). Coconut butter is considered as a functional food and could be widely used in a kitchen and home-made cosmetics.

Quality of coconut butter

You may look for organic, non-GMO, cold-pressed version. Cold-pressed means the product was not treated by hexane or other dangerous chemicals (organic solvents). Although the solvents are removed from the final products, the residuals of chemicals may still be present. Always look for cold-pressed formula of coconut butter.
