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.
The border between the US and Mexico was fixed as the Rio Grande River, and the US took undisputed control of Texas. The US also gained the present day states of Utah, Nevada, and California. Parts of New Mexico, Arizona, Colorado, and Wyoming which had been part of Mexico became American territory. The acquisition of so much territory outraged critics of the war.
