In a study that the authors describe as lending credence to the idiom, “by the skin of your teeth,” scientists are reporting that the protective shield fluoride forms on teeth is up to 100 times thinner than previously believed. It raises questions about how this renowned cavity-fighter really works and could lead to better ways of protecting teeth from decay, the scientists suggest.
Used in the proper amounts, it can make teeth stronger and aid in the treatment of osteoporosis. When excessive amounts are consumed, however, it can be a killer — a carcinogen that causes bone, lung and bladder cancers. The “it” is fluoride, a common additive in most American communities’ drinking water and an ingredient in the vast majority of commercially produced adult toothpastes.
Scientists have deciphered the structure and functional mechanism of the glucansucrase enzyme that is responsible for dental plaque sticking to teeth. This knowledge will stimulate the identification of substances that inhibit the enzyme. Just add that substance to toothpaste, or even sweets, and caries could be a thing of the past.
Even though most people are aware that good oral health is essential for the overall health of both mother and child, misunderstandings about the safety of dental care during pregnancy may cause pregnant women to avoid seeing their dentist.
