American scientists have discovered a gene blocker that they claim prevents tooth decay. This chemical could be incorporated into sweets provided by your dentist! Linden House Dentist, Sian Hayles, currently offers ‘Minimal Intervention Dentistry’ which involves chemical treatments to the roots of teeth to prevent decay. Sian comments: “With an ageing population we are now finding teeth are being lost because they simply crumble away with age. With this new technique the teeth are actually strengthened by applying chemical coatings. This could benefit children with a high decay rate as well as the elderly.”
