They also improved in memory, planning and organizational skills and in the ability to juggle several intellectual tasks at once. Doctors aren't sure why, but the lead researcher, Dr. James Blumenthal, a psychologist at Duke, believes that increasing the flow of blood to the brain may be behind it. Just as exercise improves muscle tone and function, it may have similar effects on the brain. Duke has received a grant from the National Institutes of Mental Health to study this finding further. According to a study published in the peer-reviewed journal General Dentistry, fractured teeth have become common from studs and barbells worn on the tongue.
Treatment ranges from a filling to a root canal, depending upon the severity.
The study also chronicled infections at the piercing site and a dulling of the sense of taste in some people. The academy recommends against tongue piercing. Always remove the jewelry when you eat or sleep. Clean the piercing with antiseptic mouthwash after every meal and brush the jewelry, just as you'd brush teeth, to remove plaque. The Mayo Health Clinic has reviewed the research and determined that yes, indeed, pets can improve your health.
