Women begin to lose calcium from their bones gradually starting at age 36. Calcium in the bones of premenopausal women decreases at a rate of 1 percent per year. After menopause, especially in the first five years of menopause, the loss of calcium in the bones reaches about 10%. The direct consequence of the loss of calcium in the bones is osteoporosis and shrinkage of bone tissue. Teeth grow on the upper and lower jaws, and the bone around the teeth is called the alveolar bone. Before and after menopause, with the loss of calcium in the bones, the alveolar bone will become loose and shrink, the gums will also shrink, and the roots of the teeth will gradually be exposed. Exposed tooth roots are very sensitive, a cold, hot, sour and sweet will feel pain; in addition, the exposed tooth roots are also prone to caries. Therefore, before and after menopause, women should pay special attention to oral health. Menopausal women’s saliva secretion will be reduced, oral self-cleaning effect is weakened, prone to oral mucosal diseases, such as oral mucosal dryness, recurrent oral ulcers, lichen planus and so on. In addition, the endocrine disorders of menopausal women also tend to cause abnormal symptoms of the oral mucosa, such as burning sensation of the tongue mucosa or aggravation of gingivitis symptoms. Women before and after menopause should pay special attention to maintaining oral hygiene and good dental care. Insist on brushing every morning and evening, before going to bed and waking up in the morning “knocking” exercise and massage the gums, which can slow down the resorption of the alveolar bone, promote the regeneration of the alveolar bone, to prevent gingival recession. After the age of 45, women should see a dentist at least once a year for a dental cleaning (scaling), so that women can keep their teeth stable even in old age, and let healthy teeth serve them for a lifetime.
