Is conventional toothpaste dangerous? The alternatives you need to know about

by Verónica Díez Lantarón on Jul 15, 2025
¿Es peligrosa la pasta de dientes convencional? Las alternativas que necesitas conocer

We are increasingly aware of the ingredients in the hygiene products we use daily. Shampoos, deodorants, and toothpastes are part of our routine, but just because we use them regularly does not mean that the ones we use are always beneficial for our health.

This message has resonated with a large part of the population looking for alternatives that are more respectful of their bodies. However, in the case of toothpastes, there is still a lot of misinformation. Few people know that some of their ingredients can be harmful, especially with continued use.

Is conventional toothpaste really bad?

Conventional toothpastes contain abrasive compounds and thickeners that, far from being beneficial, can harm oral health. Using this type of toothpaste is unhealthy, as some of its ingredients are classified as toxic and, being in direct contact with the oral mucosa, they have a clear pathway to enter the body , even reaching the bloodstream.

To make matters worse, many of these products come in non-recyclable plastic containers, and some include microplastics , which represents a double impact, both on health and the environment.

Some of the most common toxic ingredients in toothpastes are the following:

  • Triclosan: It is an antimicrobial compound that is closely related to thyroid problems.
  • Parabens : Many traditional toothpastes use this component in their formulation. These directly affect the hormonal system by acting as endocrine disruptors.
  • Carrageenan : Normally, this substance is used in toothpastes as a thickener. It is a derivative of algae and can cause intestinal problems.
  • Formaldehyde : This is a substance that is released by many of the preservatives used to make toothpastes, and can cause skin and eye irritation.
  • Fluoride . This component, despite what many believe, is highly toxic. In small amounts, it helps strengthen enamel and prevents cavities, but prolonged exposure can damage health.

For toothpaste to respect the oral microbiota, it is essential that it is free of any of these toxic substances but remains effective and respectful.

Should fluoride in toothpaste be avoided?

As I mentioned, the use of fluoride in toothpaste has become a topic of discussion in recent years. For a long time, fluoride has been present in dental hygiene products to prevent and fight cavities . However, in recent times, a controversy has arisen regarding its use.

According to several in vitro studies, it has been proven that fluoride can interfere with iodine absorption, an activity that is essential for the proper functioning of the thyroid , a gland that regulates almost the entire endocrine system. In addition, it has also been shown that fluoride leads to weakening of tooth enamel and greater bone wear.

Continued use of toothpastes with this ingredient can lead to unwanted stains, cause gastrointestinal problems, and even cause joint pain.

Alternatives to conventional toothpaste

If you want to start taking care of your health by changing daily habits, the way you brush your teeth is one of the first you should modify. Using conventional toothpaste can have negative long-term consequences. However, there are ways to maintain good oral hygiene while respecting our body's needs.

Natural toothpastes are a healthy, effective, and respectful option. The ideal options are toxic-free formulas, which contain ingredients such as xylitol , an anti-cavity agent that protects enamel, maintains a balanced pH, and prevents the proliferation of harmful bacteria.

One of the most innovative and sustainable alternatives are tablet and powder formats. This everyday product, presented in both innovative formats, has great health benefits by not containing toxic substances.

Tablet toothpaste, how to use it?

For many, tablet toothpaste is the best alternative to traditional toothpaste , as they are small, practical, compact, clean, and take care of the body's health. At Banbu, we have four different types of tablet toothpaste, each with unique properties and flavors. Their use is very simple:

  1. Put the tablet in your mouth and chew it.
  2. Let it dissolve.
  3. Once dissolved, brush your teeth normally, as you usually do.
  4. Rinse and... done!

These tablets are made with natural ingredients such as xylitol, turmeric, ginger, or squalene . All their compounds have antibacterial and refreshing properties that not only leave your mouth clean and fresh but also help maintain a balanced pH, preventing cavities and strengthening enamel.

Banbu's four tablet toothpastes are:

  • SUMMER: They stand out for their strawberry flavor and their cleaning action against plaque, fighting its accumulation and reducing it.
  • AUTUMN: It stands out for its cinnamon, myrrh, and cardamom flavor. It also cleans and reduces plaque and balances the pH of the oral mucosa.
  • WINTER: It stands out for its mint flavor. Its formula is anti-cavity, anti-plaque, and anti-inflammatory.
  • SPRING: It stands out for its lemon and ginger flavor. Designed for those looking for fresh breath and a healthy mouth through anti-inflammatory care.

Also available in refill format: Summer, Autumn, Winter and Spring.

Powdered toothpaste: another way of natural cleaning

Powdered toothpaste is another alternative, ideal for those looking for a simple but very effective dental hygiene routine. To correctly use powdered toothpaste, it is recommended to:

  1. Wet your toothbrush before starting.
  2. Shake off excess water from the brush.
  3. Dip the toothbrush into the amount of paste you need to use.
  4. You can repeat the process as many times as you need, but one dose is usually enough.

Thanks to its formulation rich in highly effective active ingredients, powdered toothpaste also deep cleans, helps remove stains, and leaves a natural fresh feeling without harsh chemicals.

The four Banbu powdered toothpastes are:

  • SPRING: Stands out for its lemon and ginger flavor. Designed for those who seek fresh breath and a healthy mouth through anti-inflammatory care.
  • WINTER: Stands out for its mint flavor. Its formula is anti-cavity, anti-plaque, and anti-inflammatory.

Why choose these formats?

Beyond their health benefits, there are other advantages to using these types of formats. For example, they are truly sustainable, as they don't use plastic and their containers are reusable. They are perfect for travel, as there is no risk of spillage and they can also be carried in hand luggage. Furthermore, they are health-friendly.

At Banbu, we not only transform products but also habits. Choosing solid toothpastes is not just a personal choice; it's an act of coherence with a natural lifestyle that respects yourself. Every small gesture can make a difference in taking care of your health.
