Clenching the teeth puts pressure on the muscles, tissues, and other structures around your jaw. The symptoms can cause temporomandibular joint problems (TMJ). Grinding can wear down your teeth. It can be noisy enough at night to bother sleeping partners.
From 1846 to 1848 the United States fought a war with Mexico. North Americans now know the conflict as the Mexican War, or the Mexican-American War. As a result of the war, the United States took over the land that later became New Mexico, Utah, Nevada, Arizona, California, Texas, and western Colorado.
We were not taking Mexican territory, then, in annexing Texas. The new state had come into the Union claiming the Rio Grande as her southern and western boundary. By the terms of annexation all boundary disputes with Mexico were referred by Texas to the government of the United States. President Polk sent John Slidell of Louisiana to Mexico in the autumn of 1845 to adjust any differences over the Texan claims.
