If you grind your teeth at night for a long time, you may have hypocalcemia, and you should monitor your blood electrolytes in time. If the blood calcium is reduced, you can take oral calcium gluconate, calcium in calcium and calcium dihydrochloride, etc. In serious cases, you can also push intravenous calcium gluconate, and at the same time, you can take oral vitamin D to promote the absorption of calcium, and usually get more sunshine. Patients with hypocalcemia may also have hand and foot twitching and convulsions. Children with hypocalcemia generally have abdominal pain and anterior heart pain, and may also have growth retardation. In middle-aged and elderly patients, hypocalcemia is generally manifested as signs and symptoms of osteoporosis, and in severe osteoporosis, patients can develop bone pain, which can also easily cause fractures. In addition, long-term nocturnal teeth grinding may also be caused by parasitic infections, which are usually seen mainly in children and should be seen in pediatrics if necessary.
