Women are a special group of people with different physiological characteristics and special physiological stages from men. The estrogen in the body fluctuates in stages throughout a woman’s life, affecting the gums and pulp and other tissues in the mouth, so their oral health is more unique and requires special oral health care. Women need to know different health care methods to protect their oral health at different times. In childhood, girls generally teething earlier than boys, plus like to eat snacks, so the incidence of dental caries of milk teeth is slightly higher for girls than for boys. If the caries of milk teeth is not treated in time, it will develop to the deep and form the pulpitis, and then appear the septic inflammation around the root, because the permanent tooth embryo is located just below the root class of milk teeth, if the permanent tooth embryo is infected, the development will be affected, or lead to the abnormal shape of permanent teeth, or stop the development of permanent teeth. Therefore, if the decay of milk teeth is not treated early, the toothache will prevent children from eating, and the jawbone will be underdeveloped due to the loss of normal physiological stimulation, thus causing the misalignment of permanent teeth in the future; at the same time, it will affect children to take in enough nutrition from food, and directly affect the growth and development of children in the future. During this period, we should pay attention to educate children to develop good oral hygiene habits, brush their teeth in the morning and evening after the formation of milk teeth at the age of 2-3, rinse their mouths after meals, especially pay attention to brushing their teeth before bedtime and the correct method of brushing; eat a balanced diet, eat more coarse grains and vegetables and fruits, and take reasonable calcium supplements under the guidance of doctors, which can help the oral cavity to clean itself and enhance the sturdiness of teeth; once the sulcus is found to be black, we should take the child to the dentist in time. Once the sulcus is found to be black, the child should be taken to the dentist for treatment and filling in a timely manner; sulcus closure should be performed as soon as possible after the eruption of six-year-old teeth. In adolescence, female ovaries begin to secrete estrogen, and gums, as one of the target organs of estrogen, become more reactive to inflammatory stimuli. At this stage, adolescents do not form good brushing habits, plus some oral local factors, such as the replacement of milk teeth and permanent teeth, tooth eruption, teeth misalignment, crowding, and wearing various orthodontic appliances, etc., will also affect the brushing effect. If you do not pay attention to oral hygiene, it is very easy to have swollen, congested, hypertrophied and oozing gums, which bleed when touched slightly or sucked hard, and are accompanied by pain, which is called adolescent gingivitis. If the lesion develops severely, adolescent periodontitis can occur, and the periodontal tissue is attacked and destroyed by germs very rapidly, and teeth can be loosened and displaced within 3-5 years, and in severe cases, teeth will be extracted at the age of 20 or so. According to statistics, the incidence of periodontitis in adolescents is 3-5 times higher in females than in males. The most basic treatment for adolescent gingivitis is to remove plaque and other local irritants, maintain good oral hygiene, and develop the habit of brushing teeth after meals. Only with early intervention, proper care and health care can the condition be better controlled and not further developed. Special attention should be paid to orthodontic treatment for patients with misaligned and crowded teeth during the process of tooth replacement and eruption, and attention should also be paid to choosing orthodontic appliances that are conducive to plaque control and less irritating to gum tissue, and brushing teeth with specially designed toothbrushes. And brush your teeth after every time you eat food to remove the food residue left on the tooth surface, between the teeth and on the orthodontic aligners. Before menstruation, some women experience menstrual gingivitis such as bleeding and red gums, which improves once menstruation begins. Some women have recurrent mouth ulcers, herpes, and swollen salivary glands, especially parotid glands, related to the menstrual cycle. Women’s blood coagulation decreases during menstruation, making them unsuitable for tooth extraction or various other procedures that may result in heavy bleeding. In addition, women’s painful nerves are more sensitive and their systemic resistance is relatively poor during menstruation, so dental treatment during menstruation is often painful and prone to infection. Therefore, it is best for women not to have dental treatment during menstruation. Pregnancy and breastfeeding is another period of dramatic changes in women’s bodies. Pregnancy causes a significant increase in the level of estrogen, mainly progesterone, in women’s bodies, resulting in a more intense response of the gums to inflammation than usual. Some even develop gestational gum tumors the size of a soybean to a thumb. After delivery, the inflammation will subside as the body’s progesterone level decreases, but local plaque will not return to a healthy state until it is removed, which can lead to gum recession. Studies have confirmed that women with severe periodontitis are 5-7 times more likely to give birth to low birth weight babies and premature babies than healthy women. Therefore, for the health of mother and child, women who are preparing for pregnancy should go to the hospital for a more comprehensive oral examination and care, and receive guidance on oral health preventive measures to effectively control dental plaque. In the early stages of pregnancy, the fetal organs are still differentiating and are susceptible to anti-inflammatory drugs and anesthetics, so it is not advisable to receive treatment. From the fourth to the sixth month of pregnancy, it is more suitable to receive dental treatment to avoid more caries and periodontal disease at the end of pregnancy or after delivery. Common scaling, root canal treatment, fillings and simple extractions can be performed during this period, but avoid X-ray examinations as much as possible. The last trimester of pregnancy, when the uterus is more sensitive and susceptible to contractions from external stimuli, is also not a good time to receive treatment. Tooth extraction in early pregnancy is likely to cause miscarriage, while tooth extraction in late pregnancy is likely to induce preterm labor. After pregnancy, you should pay attention to dietary nutrition, especially the intake of calcium, phosphorus, vitamin C and D, and eat less sweets and acidic foods. After the age of 45, with the onset of menopause, the loss of bone calcium accelerates and hormone levels drop rapidly, resulting in a significant decrease in oral and gingival immune function, which gives periodontitis an opportunity to take advantage of the situation and makes it easy for gum recession and exposed alveolar bone to occur. Therefore, women in this stage, not only need to pay attention to the intake of adequate amounts of calcium, strengthen exercise, in order to slow down the rate of bone calcium loss; at the same time, should also timely supplement the oral and gingival nutrition, to maintain the oral immune function of various gum and periodontal inflammatory disease vitality. Gum massage can be taken to prevent gum recession, reduce the degree of gum recession, and promote blood circulation in the gums. If the teeth are worn down and pain arises from cold or hot stimulation, they should be treated promptly, preferably with desensitizing toothpaste or acid-proof toothpaste, and avoid chewing fried and hard foods as much as possible. In a woman’s life, there are many special periods that require attentive care and more love and attention. Women should have regular checkups, regular health care and care more about their oral health. In each special physiological stage, pay more attention to oral hygiene, a balanced diet, in order to achieve effective prevention of various special physiological oral diseases, to achieve a lifetime of oral health.
