Pregnant Women and Oral Health – Myths and Truths

During pregnancy, a woman needs to pay close attention to her health and that of her baby. Besides obstetric medical care and routine exams, it is essential to have regular visits to the dentist.

Here are some myths and truths about oral health during pregnancy:

Does pregnancy weaken the teeth? MYTH

Pregnancy itself does not weaken the tooth structure. However, what sometimes happens is that during the first trimester, 70 to 85% of pregnant women experience nausea and vomiting, which can lead to dental erosion and enamel demineralization due to the contact of the teeth with the highly acidic gastric juice.

Do teeth weaken during pregnancy because calcium is lost to the baby? MYTH

During pregnancy, the mother does indeed supply calcium to the baby. However, the calcium provided to the baby is obtained by the mother through diet or supplements. The calcium present in the dental structures is stable, mineralized, and unavailable to circulate in the bloodstream. Therefore, it is impossible for the baby to “steal” calcium from the mother’s teeth.

During pregnancy, is there increased gum bleeding? TRUE

On average, 60 to 70% of women experience gingivitis during pregnancy. This gum disorder is caused by increased hormone levels, which promote the dilation of blood vessels and can trigger an inflammatory response in the gum tissues, increasing the risk of lesions in the area.

Pregnant women cannot undergo dental treatments? MYTH

A common misconception among pregnant women is that they cannot undergo dental treatments. Not only can they, but they should also visit the dentist during pregnancy. Expectant mothers should receive personalised information and protocols for oral hygiene, cleaning sessions, and guidance on their baby’s health and oral care after birth. It’s important to remember that there are safe ways to provide quality care to pregnant women. For emergency visits—due to pain, infection, or any other issue that could pose a risk to the mother and baby—there are established safe protocols for treatment during all three trimesters.

Does pregnancy increase the likelihood of developing cavities? TRUE

Due to hormonal changes during pregnancy, there is an increase in peripheral vascularization, along with a reduction in saliva flow and its protective action. Another important factor to consider is that oral hygiene care often decreases during pregnancy. Therefore, it is essential to maintain good brushing habits, daily rinsing with appropriate mouthwashes, and the use of dental floss after meals.

Is it important to visit the dentist during pregnancy? TRUE

Dental care is important for the prevention and treatment of existing disorders. Such care helps avoid potential complications that could worsen during pregnancy.
