During pregnancy, the whole organism becomes more sensitive. If there are many problems in the mouth itself or if dental protection is neglected during pregnancy, it may aggravate the existing diseases or stimulate some new ones. This will not only endanger the health of the pregnant mother herself, but also threaten the safety of the fetus. 1, easy to get dental disease during pregnancy (1) the body’s estrogen rose during pregnancy, the endocrine system has undergone great changes, easy to cause congestion and swelling of the gum tissue, vascular elasticity is weakened, the slightest external force will trigger bleeding. (2) The demand for vitamins during pregnancy is much greater than before pregnancy, if the pregnant mother does not consume enough vitamins, the fetus will directly absorb the maternal reserves, resulting in maternal vitamin deficiency causing gum bleeding. (3) The nutritional requirements of pregnancy prompt pregnant mothers to always eat more meals, and they are not able to brush their teeth and rinse their mouth after each meal, which increases the opportunity for bacteria to multiply. (4) When the calcium needed for the development of fetal bones and teeth is not enough, the calcium in the bones and teeth of the pregnant mother will dissociate into the blood, thus directly damaging the teeth. 2, three major hazards of dental disease during pregnancy (1) bacteria present in the periodontal pockets can release endotoxins and exotoxins that can affect the function of the placenta through the mother, causing miscarriage and premature birth. (2) The swelling and pain of gums and the aggravation of tooth decay will affect the digestion and absorption of nutrition of pregnant mothers and indirectly affect the development of fetus. (3) Since periodontal germs will be spread by saliva, after the baby is born, intimate actions such as kissing and feeding by the mother may pass the germs to the baby. 3, dental treatment during pregnancy five notes (1) treatment time can not be wrong simple, conservative treatment such as: fillings, dental check-ups, etc. can be carried out during pregnancy as long as the physical condition allows. More complex dental procedures are better performed in the middle of pregnancy to avoid miscarriage and malformation in the first three months or premature birth in the second three months. (2) Serious cases cannot be delayed If a pregnant mother has bleeding, redness, swelling, pain or even a rise in body temperature when her teeth are touched, she should come to the hospital no matter what the period is. Usually the doctor will take conservative treatment to relieve the symptoms of dental disease in a way that does not affect the health of the fetus and the mother. (3) Surgical procedures need to be understood Generally dental procedures given to pregnant mothers are relatively simple, no X-ray examination will be conducted and no oral antibiotics affecting the health of the fetus will be required; the dose of local anesthetic injected is low and will not inhibit the development of the central nervous system of the fetus. Therefore, the safety of the fetus can be guaranteed. (4) Post-operative dental care should not be missing Don’t think that you can rest easy after dental treatment. Pregnant mothers should remember to clean their mouths after eating or vomiting. For those who have a heavy early pregnancy reaction, they can focus on cleaning the front part of the mouth first and finally wash the back teeth area, while slowly exhaling long breaths, which can reduce the nausea and vomiting reflex. It is recommended to develop a good habit of flossing your teeth every day or even after every meal. Mouthwash should be used under the guidance of a doctor. (5) Dietary cooperation is important Pregnant moms should try to avoid foods that are harmful to dental health, such as cakes, sweet breads, candies, cookies, sugary drinks and other sweet foods. Eat more vegetables and fruits, and you can even use fruits instead of snacks, because the fiber in fruits can help clean your teeth. Drinking more milk and bone broth will help absorb and replenish calcium and increase the strength of your teeth. Dear pregnant moms, I believe that after knowing the above knowledge you will face dental disease more easily and protect your health and your baby’s health better!
