Oral health care points in the early stages of pregnancy (1 to 3 months): 1. Pre-pregnancy oral examination: If pregnancy is planned, then it is best to have a thorough oral examination before preparing for pregnancy, so that the affected teeth can be found and treated in time. Because many dental treatments require auxiliary X-rays, oral examinations should be performed at least several months in advance of the anticipated pregnancy. 2, strengthen nutrition: for most mothers-to-be, this is the most difficult period, the lingering nausea, vomiting and even mental tension, it is easy to cause the body’s nutritional deficiency, but this is an important period when the various body organs of the fetus begin to form, so the mothers-to-be should insist on eating as little and as much as possible to overcome the difficulties in order to ensure the nutritional needs of themselves and the developing baby. The mother’s body is the special environment and material basis for the growth and development of the fetus. The development of the baby’s teeth has a lot to do with the development of the fetus and the nutrition in the first year of life. Inadequate enamel development can be related to maternal calcium deficiency or the use of certain drugs during the fetal dental embryo formation stage. Throughout pregnancy, especially in the first trimester, pregnant women should maintain a normal, adequate and balanced diet, such as a balanced intake of rice, fruits, vegetables, milk, fish and meat, to provide the necessary calcium, phosphorus and vitamins for the development of fetal teeth. Although no teeth can be seen in the fetus’ mouth at the time of birth, the milk teeth actually begin to calcify when the fetus is 3 months old, and all 20 milk teeth have basically taken shape before birth. The permanent teeth begin to develop as early as 4 months of age, and the first pair of permanent teeth are already calcified by the time of birth. For this reason, it is especially important for pregnant women to take in enough calcium during pregnancy. 3.If you find any discomfort in your mouth after pregnancy, such as tooth decay and gum bleeding, you should go to the hospital in time to strengthen your oral hygiene under the guidance of a dentist, and you can do some conservative treatment temporarily. Please don’t be too nervous or even afraid, this kind of emotion is not beneficial to the fetus. If severe toothache occurs, you should see a doctor in time to do emergency treatment and relieve the pain. Some people are overly worried that dental care during pregnancy is not good for the fetus, so they have to endure the pain, which is undesirable. This is because untreated toothache may cause more serious complications. Generally speaking, in the early 3 months of pregnancy, we do not do treatment such as cleaning and extraction, but only perform conservative oral treatment, and the condition can be controlled through early local treatment, which will have no effect on the mother and the fetus.
