Kingfisher Fennel Toothpaste is all-natural, at least that is what the company claims. And by experience, we know that firms like to claim something that is not true. We believe when they say that their toothpaste is without preservatives, no flavorings and gluten-free. Also, they say it is fluoride free which is magnificent. This toothpaste was not tested on animals that mean that it is suitable for vegans.

But let talk about bad things in this toothpaste. As you already know if you are a regular reader of, every natural toothpaste have one or more bad things inside. Problematic ingredients inside Kingfisher’s toothpaste are sodium lauryl sulfate, hydrated silica, glycerine, and cellulose gum.

Kingfisher Toothpaste Ingredients:

Sodium Lauryl Sulphate – if you read some of other reviews you already know how bad this thing is. Most of the natural toothpaste companies start to drop this ingredient, and some of them want to trick their customers into changing the name of this component. This element is not needed in toothpaste. Of course, some people need to have foaming feeling in their mouth, of course, they will use SLS toothpaste. But all other people who care for their health will not be a slave of a feeling and will avoid this ingredient. SLS is not good for your teeth since it is not allowing a remineralisation process; also it is a toxic element. The body will deposit this ingredient, and it will stay in your body for five days. It will remain in your brain, liver, and other organs for five days. There are no studies that prove this ingredient is cancerogenic, but some scientists have unsubstantiated claims that this ingredient when combined with other elements, can be cancerogenic. So it is better to stay away and be safe.

I got approached by Kingfisher representative who point me on the mistake I made in the review. Kingfisher Toothpaste is not using SLS, Sodium Lauryl Sulphate. Maybe error has happened because Kingfisher uses Sodium Lauryl Sarcosinate.

What is Sodium Lauryl Sarcosinate?

It is not toxic like Sodium Lauryl Sulfate. Sodium Lauryl Sarcosinate is derived from natural plants, most probably from coconut oil. The grade for Kingfisher Toothpaste will go up because they did contact me and that means that they care about their product. And they pointed out a few things. But, still, I can’t give the highest score because even Sarcosinate has some concerns. There is concern about nitrosamines.

They are almost all carcinogenic, and Sodium Lauryl Sarcosinate in some chemical reactions with other elements may produce nitrosamines. Kingfisher needs to respond if they test they toothpaste on nitrosamines and if they are doing it regularly. Another problem is that I am not into chemistry and I apparently don’t know which elements can produce nitrosamines, so maybe they should make a statement that their toothpaste is not using chemicals that may produce nitrosamines.

Hydrated Silica – not good for teeth, same as cellulose gum, it is an abrasive element that helps clean your teeth, but in the process can harm your enamel. Cellulose gum is not a natural ingredient. So you are probably asking yourself how they claim it is natural toothpaste.

Glycerine – also not good for your teeth. With so many not so good ingredients in one toothpaste makes you believe if this is worth to use. Glycerine is another element that is bad for remineralization of your teeth. And his purpose is to give toothpaste a paste feel. So the question is: Do you brush teeth to have a paste feel, or you want healthy teeth? It is up to you to decide.

Anethole – with this ingredient thing get dirty. Anethole is flavor. Another not needed component inside toothpaste. But this cool name element is very dangerous. In some studies with rats, it increased a liver toxicity and liver cancer. There are not enough studies how this product is affecting humans but knowing it makes cancer in mice is enough good reason to stay away.

Limonene – many kinds of toothpaste use flavors. Limonene is a natural essence, but many people are allergic to it, so if you have allergic symptoms when using the toothpaste with this ingredient you can do a test and try a no Limonene toothpaste.

If you just read a title of Kingfisher toothpaste, you would think it is a safe, natural product that is very healthy for your body. In fact, it is a healthier product than conventional toothpaste. I don’t even want to review a single regular toothpaste because all of them use Fluoride, and only that is a good reason to drop them. Kingfisher Fennel Natural Toothpaste is Fluoride free, but many other ingredients don’t make a good rate for this toothpaste. By removing Sodium Lauryl Sulfate from the picture this toothpaste jumps a lot int he ratings and I can now recommend to use it. There are still some concerns but I am waiting for the answers.
