If youâre like most people, you would probably guess that itâs cavities. Unfortunatelyâ¦youâd be wrong. It is generally accepted that the leading cause of tooth loss in people over 35 is periodontitis, more commonly known as gum disease. In people under 35, cavities are the leading cause of tooth loss. Teeth are normally held firmly in place under your gums by a strong bone called alveolar bone.
There have only been four presidents of the United States who were Democratic-Republicans (Thomas Jefferson, James Madison, James Monroe, and John Quincy Adams), and only four who were Whigs (William Henry Harrison, John Tyler, Zachary Taylor, and Millard Fillmore).
Some wars were veritable incubators of future presidents: fully one-third of our presidents served in either the Civil War or Second World War. The four men who served in two wars before becoming president are Andrew Jackson, Zachary Taylor, U.S. Grant, and Dwight D. Eisenhower. It will be interesting to see if any future American presidents are veterans of the Persian Gulf War (1991) or the Iraq War (2003-2004). No doubt the president with the most colorful military career was Andrew Jackson. Already as a 13-year-old boy, he was serving in the Continental Army as a messenger.
