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 Treaty of Guadalupe Hidalgo brought a formal end to the war, and Mexico had to give up land rights. This came to be known as the Mexican Cession. The treaty transferred ownership of present-day California, New Mexico and Arizona and parts of Utah, Nevada and Colorado to the United States. In addition, Mexico relinquished its claim to Texas, and the agreement specified that the Rio Grande River would become the southern boundary of the United States.
