Pregnancy is the time wherein the pregnant woman experiences various changes and side effects in her body. One such side effect that is usually under-discussed is the formation of mouth ulcers or also called canker sores. These appear on the lips, tongue, and inner cheeks that cause pain and irritations. These mainly occur due to the hormonal changes experienced by the pregnant woman. One good thing is that these are not severe complications and can be cured very easily naturally or medicinally. Here, in this article, we will discuss the causes, types of ulcers, and the cure for these mouth ulcers during pregnancy.

What Is Mouth Ulcer?

Mouth ulcers are open sores, also known as canker sores or cold sores or Aphthous stomatitis, which are small white or yellow spots filled with water surrounded by red circles that mainly occur around the mouth. These sores occur one at a time or 3-4 at a time, sometimes these are recurrent. These occur in any trimester of pregnancy. Other than discomfort and slight pain, these sores are not much to worry about for a pregnant woman. These mouth ulcers are very common for pregnant and even non-pregnant women. This does not mean that every pregnant woman experiences these canker sores during her pregnancy; it mostly depends from person to person.

Causes of Mouth Ulcers During Pregnancy:

Mouth ulcers or cold sores are quite common in pregnant women during her pregnancy. There are no scientific pieces of evidence of the causes of mouth ulcers, but some research and studies have said that mouth ulcers may be caused due to

1. Improper Diet:

An imbalanced diet wherein the diet lacks essential vitamins and minerals like iron and zinc may cause mouth ulcers.

2. Hormonal Imbalances:

During pregnancy, the pregnant lady experiences high fluctuations of hormones. Because of these fluctuations, mouth ulcers might form during pregnancy.

3. Food Sensitivity:

The pregnant lady during pregnancy craves spicy foods. Intake of spicy or acidic foods may also cause canker sores in the mouth.

4. Stress:

A pregnant woman during her entire gestational period experiences physical and mental stress. This might also be one of the causes of the formation of mouth ulcers. Although there is no proven evidence about this point, stress is the common reason for ulcers in every individual.

5. Hematinic Deficiency:

A deficiency of iron, vitamin B12, and folate could also be one of the reasons for the formation of mouth ulcers during pregnancy.

Types Of Mouth Ulcers:

This is a bizarre thing, but mouth ulcers also have certain types. They are as follows:

A. Minor Mouth Ulcers:

These are the common type of mouth ulcers that are formed in pregnant women. The size of this type of ulcer measures between 2-9 mm. These occur on the gums, the base of the mouth, or the tongue. Usually, these ulcers heal themselves within 10-12 days.

B. Major Mouth Ulcers:

These types of ulcers are quite uncommon in pregnant women; the diameter of these ulcers is about 10mm. These ulcers form on the gums and tongue, and some of them even in the throat. Major mouth ulcers are excruciating and last for several weeks or months. These ulcers do not heal by themselves and should be treated by a doctor.

C. Herpetiform Ulcers:

A herpetiform ulcer is more of a virus than a sore. They form in clusters inside the mouth; the usual diameter of these ulcers is 1mm. These types of ulcers take 2-3 weeks to heal, leaving behind scars.

1. Turmeric:

Turmeric is considered a natural antiseptic and anti-inflammatory. The curcumin present in the turmeric helps in treating the sores. Flossing the mouth with hot turmeric water helps in easing the pain and irritations caused by the ulcers. There is no proven evidence of how turmeric helps in treating mouth ulcers; the only reason it is used is that turmeric is antiseptic.
