A new study aimed at determining whether teeth are more prone to cavities thanks to genetics has found that genetics probably don’t play as much of a role in the development of dental caries as experts first thought.
The study was conducted by the University of Melbourne and the Murdoch Children’s Research Institute at Royal Children’s Hospital in Melbourne, Australia, and followed 345 pairs of twins from the 24-week gestational age to 6 years old. What they found was at age 6, 32 percent of the children in the study had cavities (also known as dental caries) and 24 percent had what are considered "advanced cavities."
You may have seen them before – those telltale white spots on the teeth. They’re called demineralization spots, and they appear when the tooth’s enamel begins to dissolve. Though demineralization spots are bad news, the good news is they are a very early stage of tooth decay, meaning there’s still time to correct them before it’s too late. Here’s what you should do if you see demineralization spots on your teeth.
There’s no shortage of controversial topics on the news most evenings, but there’s at least one topic that shouldn’t be as controversial as it seems. It’s the great debate many towns across America are facing these days: to fluoridate or not to fluoridate the water - that, as they say, is the question. So, who’s right: The anti-fluoride activists who claim that fluoridating the water supply can cause everything from low IQ to cancer, or the medical community who say fluoridating the water helps reduce dental caries (cavities)? Decide for yourself.
