Dental Infections Can Be Harmful During Pregnancy

the dental infections they can be harmful during pregnancy for both mother and baby. It is important to understand the risks associated with dental infections and take preventive measures to maintain optimal oral health during this crucial period.

Risks associated with dental infections during pregnancy

During pregnancy, it is important for the expectant mother to inform her professional about your condition before undergoing any type of medication or treatment. Many procedures and medications are limited at this stage or require milder alternatives to avoid possible risks.

In addition, during pregnancy, women are more likely to develop dental problems such as gingivitis or tooth decay.

It is essential to treat infections in a timely manner, one Untreated dental infection can have negative consequences for mother and baby. First, the pain and discomfort associated with dental infections can affect the mother's quality of life, making it difficult to eat and sleep properly. In addition, bacteria present in a dental infection can enter the bloodstream and trigger inflammatory responses throughout the body, which can increase the risk of complications during pregnancy, such as preterm birth or low birth weight.

Why is there more predisposition to dental infections during pregnancy?

During pregnancy, the body experiences numerous hormonal changes which can increase the risk of developing dental problems. Hormones such as estrogen and progesterone can affect the gum tissues, making them more prone to inflammation and gingivitis. In addition, increased blood flow during pregnancy can exacerbate any existing dental infection.

Dental infections they can be harmful during pregnancy: How does a dental infection affect the fetus or the mother?

These are the risks that can be associated with oral diseases, especially those related to the gums:

  • Uterine myomas
  • Gestational hypertension.
  • premature birth
  • Low birth weight.
  • gestational diabetes
  • Gingivitis.


The gingivitis is an inflammation of the gums that is characterized by redness and, in some cases, bleeding. During pregnancy, increased blood flow due to high levels of estrogen and progesterone makes this condition more common, especially in the third trimester. For this reason, it is called gestational gingivitis.

Although it is not a serious disease in itself, it is related to the risks mentioned above, so it is important to go to the dentist as soon as possible. In addition, the treatment is simple and effective, as it consists of regular oral cleanings and adequate follow-up to prevent more serious complications.

If gingivitis is not treated in time, it can worsen and become periodontitis, an irreversible disease. This pathology involves the progressive destruction of the supporting tissues of the teeth, which eventually leads to the loss of the dental pieces.


Likewise, tooth decay and erosion are very common during pregnancy. Due to an increase in the acidity of the mouth, the bacteria present attack the surface of the tooth (enamel) and cause progressive demineralization.

In these cases, fillings are used, a non-invasive treatment that poses no risk to the health of the mother or the fetus.

Tips for good dental hygiene during pregnancy

Is essential that pregnant women maintain good oral hygiene and do regular visits to the dentist to prevent and treat any dental problem. Here are some tips to maintain optimal oral health during pregnancy:

  1. brush your teeth at least twice a day with a soft-bristled brush and fluoride toothpaste. Regular brushing helps to remove bacterial plaque and prevent the formation of cavities.
  2. Use dental floss every day to clean between the teeth and under the gum line. Flossing helps remove food debris and bacterial plaque in hard-to-reach areas for a toothbrush.
  3. Rinse your mouth with antibacterial mouthwash after brushing and flossing. Mouthwash helps reduce bacteria and freshen breath.
  4. Maintain a balanced and healthy diet. Limit the consumption of sugary foods and carbonated drinks, as they can increase the risk of tooth decay.
  5. Avoid smoking and drinking alcohol during pregnancy, as both habits can have negative effects on oral and general health.
  6. Schedule regular visits to the dentist for dental exams and professional cleanings. Inform your dentist that you are pregnant so that he can take the necessary precautions during treatment.
