A replacement for refills? Scientists make a material with which you can grow back natural enamel
- For more than ten years, scientists have been trying to grow glaze again
- The problem was that the new enamel did not have the correct & # 39; fish scale & # 39; structure
- It has not yet been proven that it works in the & # 39; hostile environment & # 39; of the mouth
- But experts say that re-grown tooth enamel may be a few years away from tests
It is the & # 39; holy grail & # 39; for scientists who want to save thousands of people from the misery of a trip to the dentist for a refill.
Now researchers have invented a material that can help people find their own tooth enamel naturally.
When people eat too much sugar, they get holes in their teeth where the enamel on the outside decays.
The only answer is in the dental chair, where the hole is closed with a cement or resin filling, which can lead to a possible infection or needs to be replaced a few years later when it comes loose.

For more than ten years, scientists have been trying to replace fillings with dental enamel by re-growing it by adding extra calcium phosphate.
The problem was that the new enamel did not have the correct & # 39; fish scale & # 39; structure and was therefore too soft.
But now scientists have used extra small clusters of calcium phosphate that organize in hard email within hours.
It has not yet been proven that it works in the & # 39; hostile environment & # 39; but experts say that re-grown tooth enamel may be a few years away from human testing.
Dr. Zhaoming Liu, co-author of the study at Zhejiang University in China, said: “Our newly regenerated glaze has the same structure and similar mechanical properties as natural glaze.
& # 39; We hope to achieve dental enamel re-growth without using fillings that contain totally different materials and we hope, if everything goes smoothly, to begin human testing within one to two years. & # 39;
Professor Damien Walmsley, scientific adviser to the British Dental Association, said: “Growing back teeth is the holy grail for dentistry, not least because it is so complex.
HOW TO USE AN ELECTRIC TOOTHBRUSH
- Place toothpaste on the brush head
- Hold the brush at an angle of 45 °
- Switch on the electric brush and move it from tooth to tooth
- Guide the brush along the front, back, and chewing surfaces of each tooth
- Hold the brush over each surface of each tooth for a few seconds
- Do not apply too much pressure or scrubbing. Simply guide the brush over each tooth
- Continue for approximately two minutes to ensure that each tooth is clean
- Afterwards, rinse the brush head with water and let it dry

& # 39; We would like to see the end of the fillings and this is a step closer to the fact that scientists can grow their teeth back, although this is the beginning of the journey and there is still a long way to go.
& # 39; For now, we want people to avoid fillings by visiting their dentist, brushing twice a day with fluoride toothpaste and reducing the amount of sugar they eat. & # 39;
Tooth enamel is the most difficult part of the human body, but it cannot repair itself, making tooth decay one of the most common diseases in the world.
The Chinese researchers, whose study is published in the journal Science Advances, are not the only ones trying to regenerate enamel with artificial calcium phosphate – the most important ingredient in human teeth and bones.
The breakthrough is the use of ultra-small clusters of calcium phosphate to form the correct structure of tooth enamel, which looks like fish scales.
When this was done on human teeth, a thin probe test showed that the re-grown enamel was just as hard as regular tooth enamel.
In two days it grew to almost three micrometres thick, which is about one-thirtieth of the thickness of a human hair.
Professor Alvaro Mata, who is also working on the re-growth of dental enamel using a protein matrix from Queen Mary University of London, said: & # 39; It's one thing to grow enamel in the laboratory and another to put it in the laboratory hostile and harmful environment of the mouth. , but human testing can take three or four years.
& # 39; I am often contacted by people who are desperately looking for this type of technology because diluted or etched tooth enamel can cause a lot of pain.
& # 39; Although there are important challenges that need to be addressed, this is an encouraging study that brings us one step closer to solving this important social and medical problem. & # 39;
ARE TRENDY WAYS TO CLEAN YOUR TEETH EFFECTIVELY OR DANGEROUS?
Top dentists reveal how trendy fads can destroy people's teeth.
Although Gisele Bündchen and the Hemsley sisters swear by starting each morning with a refreshing glass of warm water and lemon, Dr. warns. Ben Atkins, a dentist in Manchester and Trustee of the Oral Health Foundation, that the drink effectively dissolves teeth and even darkens them.
While critics associate fluoride with everything from dementia to diabetes, experts claim that numerous studies show that the mineral does not harm human health, with varieties free & # 39; the most important protective ingredient & # 39; to miss.
Dr. Atkins also describes the ancient Ayurvedic practice of oil pulling, where coconut oil is tossed around the mouth, as a & # 39; waste of time & # 39; Rhona Eskander, Best Young Dentist Winner 2016, adding that it won't give you a Hollywood smile.
In terms of brushing teeth with charcoal or apple cider vinegar, both Dr. Atkins as Dr. Eskander admits that the & # 39; natural remedies & # 39; do more harm than good, while their acidic, abrasive consistency can remove surface stains, they can also permanently damage enamel.
