During pregnancy, mothers pay the most attention to their fetus; often ignore their own dental health. A dentist had pointed out that there are many women have defective teeth before their pregnancy, dental diseases can exacerbated during pregnancy, but many women generally thought that the fetal is absorption all the maternal calcium and that pregnant women is prone to dental diseases, in fact, this is a problem, coupled with the thought that X-ray during pregnancy, medication and dental checkup will affect the fetus. As the dentist explained, such as the mother had dental problem prior their pregnancy, the hormones in the body in pregnancy changes, this will be more favorable to increase periodontal bacteria, at the same time, due to vascular easy expansion and dental meat tissues become fragile, causing inflamed gums and teeth of blood flow such as inflammation, severe tooth will fall off. If there is dental problems, pregnant women can basically cure, early pregnancy stage should be avoided the X-ray procedure, the later stages is not a problem, because during the course of treatment, the dentist will help pregnant women to wear protective clothes to hinder the body absorption of the radiation, coupled with the current use of the advanced X-ray, radiation level is very low, so pregnant women need not worry too much about.

A professor from Hong Kong University suggested, emphasizing the best decisions of women before pregnancy, first make a detailed oral examination, for example, to pay special attention to periodontal disease, tooth decay and wisdom teeth problems, so early diagnosis and treatment can be effective in reducing pregnancy teeth unnecessary trouble. In addition, pregnant women should change their eating habits, meal frequency from the 1 day 3 meals into around 6-7 meals, and should avoid having too much acidic or sweet snacks, which will increase the chance of tooth decay. The best prevention is to keep the oral area clean after each meal and should have the teeth brushed and use dental floss to help clean and avoid excessive snacking (plum, lemon and tangerine peel), can greatly reduce the chance of food acid damage to teeth.
