Want a better toothpaste? Just add wool
A new additive of toothpaste of sustainable origin could soon transform the way we strengthen – and even restore – moving or lost to the enamel of the teeth. However, this potential ingredient of changing dentistry is not harvested from rare or complex sources. Instead, the protein can be found in everyone’s hair, skin and nails.
Dental enamel did not reconstruct and keep it is not easy. The natural protection barrier that lines our chompres inevitably claims during your life, but very acidic diets and poor dental hygiene often worsens deterioration. The loss of the outer layer frequently causes teeth sensitivity, acute pain and ultimately tooth loss. Fluoride remains one of the safest treatments to avoid deterioration, but it is not able to promote the regrowth of the enamel or to replace what has already disappeared.
“Unlike bones and hair, loss of enamel does not regenerate,” said Sherif Elsharkawy, King’s College London prosthodontics consultant in a statement. “Once lost, let’s go forever.”
Recently, Elsharkawy and his colleagues wondered if a very resilient protein called keratin could somehow help reinforce the teeth. After extracting the sheep wool keratin, the team added it in a composite mixture which they then applied to the surfaces of human molars. They quickly realized that the protein quickly combined with the naturally present minerals of the saliva to form a well -organized crystalline scaffolding structure which shares a remarkable similarity with enamel. Once joined to a tooth, the layer continued to attract phosphate and calcium ions to continue cultivating a new protective coating – effectively regenerating the lost enamel. Their results were recently published in the journal Advanced health equipment.
“Not only does it come in a sustainable way from organic waste such as hair and skin, but it also eliminates the need for traditional plastic resins, commonly used in restorative dentistry, which are toxic and less durable,” said the study to the first author and clinician of repair dentistry Sara Gamea.
Gamea added that unlike plastic resins, keratin seems simply more natural and can be modified to correspond more closely to the color of an original tooth.
Elsharkawy and Gamea believe that their revolutionary solution to almost omnipresent dental concern is perhaps only 2 to 3 years to become accessible to the public. They provide that the keratin -based mixture could be added to over -the -counter toothpaste such as fluoride, or used in targeted repairs to a dentist by applying it as a nail polish.
“With the subsequent development and good partnerships in the industry, we could soon become stronger and healthier of something as simple than a haircut,” said Elsharkawy.
The repair of the infused enamel in keratin is one of the last people in the growing health waste industry, which aims to reuse materials thrown for medical solutions.
