Toothpaste ingredient repairs teeth while you sleep
A new toothpaste technology, known asBioMin, is designed to replace minerals lost from tooth enamel,working while the user sleeps to prevent decay. Available to dentistsas a toothpaste called BioMinF, and set to be marketed to consumersin the near future, the product is long-acting, and also tacklessensitivity.
Dental decay and sensitivity isextremely prevalent, with some 42 percent of children between theages of 2 and 11 affected by it, and a whopping 92 percent of adultsbetween 20 and 64 having to deal with it at some point.
A new toothpaste called BioMinF, based on research from the Queen Mary University of London and Imperial College London, aims to tackle dental decay through a slow release of calcium, phosphate and fluorideions. Whereas normal toothpastes wear off after only a couple ofhours, BioMin pastes work for 8-12 hours after brushing, with theflouride – which is resistant to the acid found in things like softdrinks – forming a protective layer over the enamel.
The calcium and phosphate do even more,working with the saliva in the mouth and combining to form a newmineral that's able to strengthen and rebuilt the tooth structure.Sensitivity is tackled by forming a barrier over open tubules, whichprovide access to open nerves. The BioMin tech seals off the nerves,lowering sensitivity, particularly to hot and cold food and drink.
Interestingly, the new sensitivity anddecay-tackling toothpaste tech could, according to the team behindit, also appear in other dental hygiene products.
"The technology behind BioMin is nothowever exclusively designed for toothpastes," said the company'schief scientific officer Professor Robert Hill. "It can also beincorporated in other professionally applied dental products such ascleaning and polishing pastes, varnishes and remineralizing fillingmaterials."
BioMin Technologies – the companybehind the breakthrough ingredient – is aiming to commercialise thedevelopment of the product, with a fluoride-free version also in theworks. The BioMinF toothpaste is available todentists via wholesalers right now, priced at £5 (US$7) for a 75 mltube. For everyone else, you can expect the new paste to be onstore shelves by the end of the year.
