New toothpaste can regrow teeth

The $3 billion global market for toothpaste is on the verge of a shake-up as new biotechnologies come through that not only curtail sensitivity problems but will also enable teeth to re-grow to fill in small cavities. Today’s toothpaste comes in a plethora of flavours and can of course whiten teeth but from a medical viewpoint, little has progressed in the 40 years since fluoride was added to fight decay.
Now though scientists in various countries have developed differing technologies that produce similar results to deaden sensitivity and recalcify the teeth, problems that have increasing significance as populations age. Researchers have found fluoride ceases to be as effective with older people. That’s because the elderly have more difficulty generating the large amounts of saliva – loaded with calcium and phosphate - necessary to combine with fluoride to resist the demineralisation of teeth. Also, said Richard Bernholt, managing director of west London-based dental care company Periproducts: “The older you are the more likely you are to have gums receding and sensitivity problems because of what you eat.”
Periproducts, which sells Retardex products in the UK, has licensed NovaMin technology from a Florida firm of the same name and hopes to be the first company to have it formulated in a retail brand in the UK later this year. Periproducts plans to launch its new toothpaste in October at the British Dental Trade Association exhibition at NEC Birmingham. The company wants to get its as-yet-unnamed toothpaste with dentists and into the retail chain before the big names in oral hygiene – Colgate-Palmolive, GlaxoSmithKline, Johnson & Johnson, Unilever and Procter & Gamble reformulate their products with NovaMin or competing calcium phosphate compounds.
