The tooth is the only part of the human body that can’t repair itself
June 5, 2016
The tooth is the only part of the human body that can’t repair itself and tooth enamel is the hardest of all substances manufactured by the human body. Each tooth contains about 55 miles of canals for a total of over 1700 miles. There are 20 baby teeth and 32 adult teeth. False teeth are often radioactive. Approximately 1 million Americans wear some form of denture; half of these dentures are made of a porcelain compound laced with minute amounts of uranium to stimulate fluorescence. Without the uranium additive, the dentures would be a dull green color when seen under artificial light. If you are right-handed, you will tend to chew your food on the right side of the mouth. If you are left-handed, you will tend to chew your food on the left. A pack-a-day smoker will loose approximately 2 teeth every 10 years.
