New gel restores dental enamel and could revolutionise tooth repair (nottingham.ac.uk)

Article summary

Scientists have developed a new gel that can repair and regenerate tooth enamel, potentially revolutionizing dental treatment. The gel works by mimicking natural proteins that guide enamel growth and can be applied to teeth in a similar way to fluoride treatments. It has been shown to create a thin, robust layer that promotes the growth of new mineral, recovering the structure and properties of natural healthy enamel. This breakthrough could help address enamel degradation, a major contributor to tooth decay affecting nearly 50% of the world's population.

What commenters say

• Some commenters are skeptical about the article's claims, having read similar stories in the past with little progress.
• Others note that significant progress has been made in treating HIV and cancer, and express hope that similar breakthroughs will occur in other areas, such as tooth regrowth and hair regrowth.
• There is a sense of frustration and disappointment among some commenters who have been waiting for a cure for tooth decay or hair loss, and feel that it is perpetually out of reach.
• A few commenters share personal anecdotes about their experiences with dental anxiety and the importance of regular dental care, highlighting the need for effective and accessible treatments.
• Some commenters discuss the complexity of regrowing teeth versus hair, with teeth being a more specific material to replicate, whereas hair growth is a complex process linked to various factors.
• The progress made in HIV treatment is acknowledged, with some considering it a virtually won battle, while others point out that the treatment still has unpleasant side effects and is not entirely inconsequential.
• There is a brief discussion on the efficacy of flossing, with some commenters questioning its benefits and others providing evidence that it may not be as effective as previously thought.
• The conversation also touches on the idea that some medical breakthroughs may take time to become widely available and affordable, with some treatments being expensive or only accessible to certain populations.
