More than nine out of 10 Americans under the age of 64 have some degree of tooth decay, according to a report published by the CDC’s National Center for Health Statistics. Although the outer layer of teeth, or enamel, is the hardest substance in the human body, it can be destroyed by bacteria. Oral bacteria break down food and release acids that decay the enamel. Over time, this can lead to a cavity, which cannot be reversed. Agoura Hills cosmetic dentist, Dr. Philip Shindler, comments on a recent study that links genes to the bacteria to blame for tooth decay.

The microbiome in a human mouth is affected by many things, including genetics, according to a recent study that was published in “Cell Host & Microbe.” During the study, researchers evaluated 485 twins so that they could eliminate questions of nature versus nurture. The 205 identical twins had oral microbiomes that were more similar than those of the 280 fraternal twins, which the researchers theorized indicated that genetics influence oral bacteria. However, researchers emphasized that the bacterial strains most strongly linked to genetics were not those linked to tooth decay. Lifestyle and dietary habits tended to be responsible for higher rates of decay and decay-causing bacteria.

Tooth decay is not the only major public health issue; gum disease is also common and associated with tooth loss and major dental health issues. Both tooth decay and gum disease are highly preventable. One of the most basic cavity prevention measures is plaque removal and a diet low in sugar. Bacteria live in plaque and feed on sugar, so brushing, flossing and limited sugar consumption targets the factors that cause tooth decay.

Brad grew up in a small town in northern Iowa. He studied chemistry in college, graduated, and married his wife one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children.
