About Tooth Abscess

An abscessed tooth or tooth abscess is the formation and collection of pus in different parts of a tooth due to bacterial infection. It can result in swollen gums, toothache or both (1).

Causes Of Tooth Abscess When Pregnant

An abscess tooth can occur due to many reasons (2):

  • Tooth decay

Mild to extensive tooth decay can lead to severe infection in the oral cavity. The infection may result in abscess formation in the damaged tooth.

  • Periodontal disease

Severe trauma to the gums and food accumulation can lead to bacterial growth and cause inflammation and infections of the gums and the tissues supporting the teeth. This leads to pus in the surrounding tissues and results in an abscessed tooth.

  • Chipped or broken tooth

Cracks in the tooth enamel allow bacteria to infect the pulp. The infection in the pulpal tissue eventually leads to complete damage of the pulp and then to an abscessed tooth.

Symptoms Of Tooth Abscess During Pregnancy

There are many symptoms of tooth abscess during pregnancy. Some common symptoms that you may experience include (1) (2).

  • Toothache
  • Headache, ear ache, jaw pain due to pain radiating from the infected tooth
  • Teeth sensitivity
  • Swollen gums, neck glands, and jaws
  • Fever

Dental Health And Pregnancy

During pregnancy, your body undergoes many hormonal changes. These changes can increase the risk of dental problems such as tooth decay and gum diseases. Therefore, maintaining dental health during pregnancy is important (3).

Some pregnancy complications that occur due to dental problems include:

  • High risk of preterm births.
  • High risk of health problems in preterm babies.
  • The spread of abscess to other parts of the body, which could cause severe health complications such as Ludwig’s angina.
  • High risk of early childhood tooth decay problems.

Tooth Abscess During Pregnancy

If you are pregnant and experience pain or discomfort in your teeth, consult your obstetrician/gynecologist and your dentist.

It is also important to tell your dentist about your pregnancy so that they won’t resort to X-rays during your pregnancy as radiation can harm the fetus. Your pregnancy will also determine if you are an ideal candidate for a procedure that requires anesthesia and the type of medicines you can take for your treatment.

Preventing Tooth Abscess When Pregnant

By now, you know why it is important for women to prevent abscess tooth or dental problems during pregnancy. Here are some simple preventive measures to follow (4):

  • Brush and floss twice daily. Use a toothbrush with soft bristles and consult your dentist to use the right toothpaste during your pregnancy.
  • If you are trying to get pregnant, go for periodical dental check-ups to ensure no or minimal problems during your term.
  • Vomiting during pregnancy can cause tooth decay due to the acidic nature of the vomit content. To avoid any dental problem due to vomiting during pregnancy, rinse your mouth after a vomiting or retching episode.
  • Avoid eating sugar-rich foods and rinse your mouth after you eat anything.

Frequently Asked Questions

1. Can a tooth infection spread to my baby?

The causative agent of a tooth infection might spread to the baby when pregnant and after birth. This spread might make the baby vulnerable to teeth infections in the future (5).

2. Can a tooth abscess cause a miscarriage?

Uncontrolled infection of the gums has been linked to adverse pregnancy outcomes. These outcomes could either be because of the changes in the maternal immune system during an infection or the direct effect of the causative agent on the uterus. However, more studies are needed to identify the relationship between tooth abscess and miscarriage (6). Therefore, it is advised to maintain proper dental hygiene during pregnancy.

3. Can I take antibiotics for tooth abscesses while pregnant?

Antibiotics are one of the intervention strategies to treat tooth abscesses. Therefore, your dentist might prescribe you an antibiotics course to reduce the infection (7). However, a few antibiotics like streptomycin, tetracycline, and kanamycin are not safe for pregnant women (8). Hence, avoid self-prescription or administration of antibiotics during pregnancy and seek medical advice for any treatment.
