Toothpaste Made from Hair Could Help Repair and Protect Teeth

 

A Breakthrough Discovery in Dental Science

Researchers from King’s College London have made a surprising discovery — toothpaste made from hair could one day help repair and protect damaged teeth. The study reveals that keratin, a natural protein found in hair, skin, and wool, can rebuild tooth enamel and prevent early signs of decay.

This finding opens new doors in dentistry, offering a sustainable and biological way to strengthen teeth without relying on traditional synthetic materials.

How Keratin Helps Repair Tooth Enamel

Keratin plays a crucial role in maintaining the structure of hair and skin. According to the research, when keratin is applied to the surface of a tooth and interacts with the minerals found in saliva, it forms a highly organized, crystal-like structure. This structure closely mimics natural enamel, creating a protective layer around the tooth.

Over time, this keratin-based coating continues to attract calcium and phosphate ions, which are essential for enamel strength. The process results in a durable, enamel-like layer that helps protect against sensitivity, decay, and further erosion.

The Science Behind the Discovery

Dr. Sara Gamea, PhD researcher at King’s College London and the study’s lead author, explained that keratin offers a transformative alternative to conventional dental treatments. The team extracted keratin from wool and used it to develop a coating that could rebuild enamel naturally.

Unlike bones or hair, tooth enamel does not regenerate once it is lost. This makes enamel erosion a serious and permanent problem for many people. Factors such as acidic foods, sugary drinks, poor oral hygiene, and aging all contribute to enamel wear, leading to sensitivity and tooth decay.

By using keratin, scientists have found a way to restore enamel-like protection using materials already present in the human body.

A Sustainable and Eco-Friendly Solution

One of the most exciting aspects of this innovation is its sustainability. Keratin can be sourced from biological waste materials such as hair, wool, or skin. This not only reduces waste but also eliminates the need for traditional plastic resins used in many dental treatments.

Plastic resins are often toxic and less durable compared to natural biomaterials like keratin. Using keratin-based formulations could make future toothpaste and dental coatings safer, more effective, and environmentally friendly.

Dr. Gamea highlighted that this breakthrough bridges the gap between biology and dentistry. It represents a shift toward biomimetic approaches — using natural materials and biological processes to restore the body’s own functions.

The Future of Tooth Repair and Regeneration

While the study is still in its research phase, it offers hope for a future where damaged teeth can repair themselves with the help of biological materials says dentist in shell cove. With further development and support from the dental industry, keratin-based products could revolutionize how we approach oral care.

As Dr. Gamea noted, “We are entering an exciting era where biotechnology allows us to not just treat symptoms but restore biological function using the body’s own materials.” In the near future, something as simple as a haircut could contribute to growing stronger, healthier smiles.

Conclusion

The discovery of keratin’s role in repairing enamel marks a major advancement in dental science. By using a natural protein found in hair, researchers have shown that it is possible to create sustainable, enamel-like coatings that protect and strengthen teeth. This innovation not only offers a new path for oral health care but also aligns with global efforts toward eco-friendly and regenerative solutions.

Frequently Asked Questions

What is keratin?
Keratin is a structural protein found in hair, skin, nails, and wool. It helps maintain strength and flexibility in these tissues.

How can keratin repair teeth?
When applied to the tooth surface, keratin interacts with minerals in saliva to form a crystal-like layer that mimics natural enamel.

Is this toothpaste available to the public?
Not yet. The research is still in development, but scientists are optimistic about future applications.

Why is enamel repair important?
Enamel protects the inner layers of the teeth from decay and sensitivity. Once lost, it cannot regenerate naturally, making protection vital.

Is this method eco-friendly?
Yes. Keratin can be extracted from waste materials like hair and wool, offering a sustainable alternative to synthetic dental materials.
