BioMin F stands out as the only toothpaste offering a continuous release of low-level fluoride, calcium, and phosphate ions for up to 12 hours post-brushing. This extended protection contrasts sharply with conventional toothpastes, where soluble fluoride is quickly washed away by saliva, often diminishing in effectiveness within an hour after brushing.
The concept of using bioglass in dental care originated over two decades ago. Initially developed for orthopedic bone grafting, the first-generation NovaMin bioglass was later adapted for dental use due to its ability to adhere and slowly dissolve, releasing calcium and phosphate. However, NovaMin, which is a key ingredient in certain other toothpastes, lacks fluoride and does not provide an optimal balance of calcium and phosphate.
BioMin F, developed over 15 years at Queen Mary University of London, represents a significant advancement in bioglass technology. This second-generation bioglass is specifically engineered for dental applications. It is designed to deliver fluoride, calcium, and phosphate ions slowly over 12 hours, facilitating the formation of stable, acid-resistant fluorapatite both on tooth surfaces and within dentinal tubules. This process enhances tooth acid-resistance by up to 1000%, a marked improvement compared to the fleeting protection provided by soluble fluoride in other toothpastes.
A common misconception is that a toothpaste should contain 1450 ppm of fluoride to be effective. This figure is not based on clinical efficacy but rather represents the legal maximum fluoride content allowed without requiring extensive product registration. Higher fluoride concentrations can increase the risk of fluorosis, particularly in children and individuals who may swallow toothpaste. BioMin F circumvents this issue by using a controlled release mechanism, maintaining a lower fluoride concentration of 530 ppm while still offering sustained protection over 12 hours.
BioMin F is formulated with fluoride, calcium, and phosphate in optimal proportions. This balanced composition ensures that as the oral pH drops after consuming acidic or sugary foods, the bioactive glass dissolves more rapidly, releasing minerals that neutralize acid and stabilize the pH, thereby protecting teeth from decay.
Moreover, the bioglass particles in BioMin F are 60% smaller than those in NovaMin products, which reduces abrasivity and enhances the depth of penetration into dentinal tubules. This improved tubular occlusion is more resistant to dissolution, providing more effective and lasting relief from dentine hypersensitivity. BioMin F offers unparalleled enamel strengthening and long-term defense against sensitivity, setting it apart from other toothpastes on the market.
