Recent scientific studies have shown that pregnant women suffering from gum inflammation or periodontitis (normal phenomena due to hormonal changes) are more likely to have premature labour and underweight babies. Bacteria which develop and exist in an unhealthy oral cavity pose a direct risk to both the pregnant woman and the fetus. Therefore, special care and monitoring of the oral health of a pregnant or prospective pregnant woman by her dentist are required, and immediate restoration and treatment of any diseases, such as gingivitis and periodontitis.
