Dupont bristles - Benefits and Sustainability

Oral hygiene plays a vital role in maintaining overall health, and brushing our teeth is an essential part of our daily routine. Behind many effective toothbrushes lies an innovation that has transformed oral care - the Dupont bristles.

Dupont begins its commercial production in 1938, replacing the use of pig neck hairs on toothbrushes. In this blog post, we explore these innovative bristles  understanding their benefits, sustainability, and the role they play in promoting a healthier smile.

1. Unparalleled durability

Dupont bristles are renowned for their exceptional durability, making them an ideal choice for toothbrushes. Unlike traditional nylon bristles, Dupont bristles are made from a special material known as Tynex developed by the renowned company DuPont. This advanced material ensures that the bristles maintain their strength and shape even after extended use, providing consistent and effective cleaning performance.

2. Gentle and effective cleaning

The design of Dupont bristles allows for a gentle yet thorough cleaning of teeth and gums. These bristles are finely tapered, making them softer and more flexible compared to conventional bristles. The tapered design enables the bristles to reach deeper into hard-to-reach areas, such as the gaps between teeth and along the gum line, ensuring a comprehensive cleaning experience without causing damage or irritation to delicate oral tissues.

3. Enhanced plaque removal

One of the primary goals of brushing is to remove plaque - a sticky film that harbors harmful bacteria and can lead to dental issues such as cavities and gum disease. Dupont bristles excel in plaque removal due to their superior flexibility and density. The fine, densely-packed bristles effectively dislodge and remove plaque from the tooth surfaces, helping to prevent dental problems and maintain oral health.

4. Hygienic and long-lasting

Dupont bristles are designed to resist bacterial growth, making them more hygienic compared to traditional bristles. The durable nature of these bristles ensures that they maintain their integrity even with prolonged use, reducing the need for frequent replacements. This longevity not only contributes to a more sustainable oral care routine but also provides users with a consistent brushing experience over an extended period.

5. How to dispose of them

Dupont is helping to enable circular solutions through the mechanical recycling of its bristles. To dispose of Dupont bristles responsibly, separate the bristles from the toothbrush handle. If you use a bamboo toothbrush, the bamboo handle can go in the organic waste, or be recycled. And the bristles should be collected all together in a small container/bag and be disposed of in the plastic bin - they are fully recyclable.

Is there a more sustainable option for Dupont Bristles?

Some companies have introduced toothbrushes with bristles made from plant-based materials, such as castor bean oil. While the bristles are technically made from castor beans, lots of chemical processing turns them into Nylon-11. Thus, these bio-based bristles are still plastic and cannot biodegrade. Their advantage is that they do not derive from petroleum. The only compostable bristle material on the market currently is boar hair – which is not the best option for vegans. Because of it, you still can find most sustainable toothbrushes made with Dupont bristles.


When you choose a toothbrush equipped with Dupont bristles, you can ensure an effective and comfortable brushing experience. However, it is crucial to remember the importance of responsible disposal to ensure not only cleaner teeth but also a cleaner planet. By properly disposing of Dupont bristles, we can contribute to reducing waste and minimizing the environmental impact of our oral care habits.
