The process of conceiving love crystals is always accompanied by the joy and happiness of the whole family, while everyone is eagerly waiting for it, don’t let the caries in the mother-to-be’s mouth become a hidden danger to the baby’s health …… A. Pregnancy and dental caries As the saying goes, “A baby loses a tooth”. Nowadays, many people still think that the fetus has to absorb calcium from the mother’s teeth during pregnancy, so it is normal for pregnant women to have tooth problems. This phenomenon may be common, but just because it is common doesn’t mean it should happen. Statistics show that about half of pregnant women suffer from tooth decay. Due to the hormonal changes in women’s bodies during pregnancy, many pregnant women experience vomiting and acid reflux in early pregnancy, which causes changes in the bacterial population in the mouth – the oral environment becomes more suitable for the development of tooth decay. There are also many pregnant women who have increased early pregnancy reaction when brushing teeth, nausea and vomiting, so they brush their teeth twice a day or simply do not brush their teeth, plus the change of diet during pregnancy, all these special circumstances will “trigger” tooth decay. Some women have tooth decay before they are pregnant, but they don’t check and treat it in time. During pregnancy, due to the influence of various factors, the decay becomes more and more serious and develops into acute pulpitis or even periapical inflammation of teeth, which is unbearable. Many pregnant women are afraid that the treatment process and medication will affect the growth and development of the fetus, so they are afraid to take medication or go to the hospital to tolerate the toothache and let the disease teeth run wild. It’s hard enough to carry a baby in October, so why add so much pain that you shouldn’t have to endure for no reason? Do you know? There are many bacteria in the mouth with cavities, and the toxins produced by these bacteria will increase the risk of preterm birth and low birth weight babies. If the mother has cavities, the bacteria in her mouth can also be transmitted to her newborn baby through kissing and sharing utensils. We recommend every woman who is preparing to get pregnant to go to the hospital 6 months in advance for a systematic oral health consultation: dental cleaning to get rid of caries in the mouth, root canal treatment teeth with hidden problems, vestigial roots and crowns, abnormally positioned wisdom teeth, etc. In addition, the oral health of men will affect the quality of sperm, the father-to-be should also be in the “baby” before the active oral health examination, the husband and wife work together to welcome the new life together with a healthy and fresh oral environment! Second, oral health care during pregnancy Due to the special nature of pregnancy, mothers-to-be need to spend more thought to maintain oral health. 1, basic oral hygiene care: use fluoride toothpaste, brush your teeth at least twice a day, at least three minutes each time, pregnant women had better keep five minutes. Floss every day, and if you can brush and floss after every meal, that’s even better! If normal brushing makes you nauseous and vomit, try switching to a lighter tasting toothpaste, you will feel much better. It is recommended to rinse your mouth with baking soda after each vomit, which can effectively remove the residual stomach acid in your mouth and reduce its corrosion on your teeth. In addition, it is recommended that pregnant women use non-prescription mouthwash without alcohol to rinse their mouths before going to bed every day. 2.The use of xylitol: Research shows that xylitol can inhibit the growth of bacteria causing dental caries in the mouth, stimulate saliva secretion and reduce plaque formation, which is very helpful for pregnant women to prevent dental caries. It is suggested that mothers-to-be chew xylitol gum after every meal, which is also an effective way to reduce the risk of dental caries for babies. 3.Balanced diet: Pregnant women need to take in sufficient protein, calcium and vitamins. Therefore, fresh vegetables and fruits, whole grain foods, dairy products, fish, meat and eggs, beans and nuts are all great choices. 4. Reduce the intake of sweet food: candy, cakes, cookies, carbonated drinks and other sugary foods can promote the development of dental caries, so it is recommended to eat less during pregnancy. Dried fruits such as raisins or figs will also stick to the grooves on the surface of teeth, so make sure to brush and rinse your teeth after eating these foods. 5.Other tips: drink more water; try to eat less and more in order to reduce the early pregnancy reaction; don’t smoke and refuse to inhale second-hand smoke!
