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).
There have been 18 Republican presidents and 15 Democratic presidents. Actually, while the Democratic Party tends to claim Andrew Johnson as their own, he was sworn into office in 1865 while he was a member of the National Union Party. This would technically make it 18 Republicans to 14 Democrats. Since the first presidency in 1789, and until 2013, there have been 44 total presidencies in the United States. This includes only those presidents who were sworn into office, not acting presidents. Of course, not all of those who held office have been Democrats or Republicans.
