The human brain is a marvelous piece of organic design. The organ controls the nervous system in all vertebrates, including humans. The hub of what helps distinguish man from the rest of the animal kingdom processes about 70,000 thoughts a day and in order to keep the synaptic connections sharp, daily brushing and flossing are necessary.
According to a study conducted by a team of British psychiatrists and dentists, “…gingivitis and periodontal disease were associated with worse cognitive function throughout adult life, not just in later years.” (http://www.prevention.com/health/brain-health/surprising-tips-boost-your-brain). The information was unearthed after the team analyzed thousands of subjects aged 20 to 59. They suggest following dentist recommendations of brushing teeth twice daily for two minutes a session, plus flossing every day to remove dental plaque. A solid preventive oral health regime will keep you sharp, regardless of your age.
