Are Mouth Ulcers Common In Pregnancy?

Mouth ulcers, also known as canker sores, are as common in pregnant women as they are in nonpregnant women. However, you need not worry as these are temporary and could go away within a week or two.

You might get just one sore at a time or three to four at once. Sometimes, mouth ulcers could be recurrent. They usually look like small spots filled with water and commonly occur on the tongue, inner cheeks, or on the inside of the lips.

Other than the discomfort and pain they cause, mouth sores do not have any serious effects on your pregnancy.

Read this MomJunction post to know the causes of mouth ulcers in pregnancy and treatment methods to get rid of them.

Why Do You Get Mouth Ulcers When Pregnant?

The exact causes of mouth ulcers in pregnancy are not known. However, there are different theories (1) (2) (3).

  1. Hormonal changes: Fluctuation of hormones during pregnancy could be one of the reasons for canker sores on your lips, inside the cheeks, or on your tongue.
  1. Stress or trauma: Physical trauma (toothbrush, tongue bite, etc.) or stress could also cause mouth ulcers. Although there is no specific evidence to prove this theory in the case of pregnant women, they are the common reasons for mouth ulcers.
  1. Food sensitivity: Food allergies (especially with acidic or spicy foods) might be responsible for canker sores in the mouth.
  1. Hematinic deficiency: Deficiency of folate, iron, and vitamin B12 could also be responsible for developing mouth ulcers. However, taking proper and relevant medications or supplements can help in reducing canker stones. This is a common etiology.
  1. Others: Stress, weak immunity, tobacco, or broken teeth or dentures could be some other reasons for getting mouth ulcers.

Understanding the symptoms and signs will help you figure out what kind of mouth ulcers you have so that you can treat them accordingly.
