This New Toothpaste Ingredient Promises to Harden Teeth While You Sleep
Tooth decay and tooth sensitivity affect a lot of people—and their smiles. And now, according to the Queen Mary University of London, it might be something a new toothpaste ingredient can fix as you drift off into dreamland.

The ingredient, BioMInF, claims to release lost minerals, including the two key ones of calcium and phosphate. Together, the duo combines to form new tooth mineral, in turn, rebuilding, strengthening and protecting the tooth’s structure.

Using remineralizing toothpaste makes teeth far more resistant to attack from acidic soft drinks like fruit juices and sodas. It is also much more effective than conventional toothpastes where the active ingredients, such as soluble fluoride, are washed away and become ineffective less than two hours after brushing,” said professor Robert Hill, chair of Dental Physical Sciences at Queen Mary University of London, who led the team which developed BioMin.

Right now, the toothpaste is available in the UK via dental offices with a bigger rollout expected by year’s end.
