Canker Sores Early Pregnancy – Mouth Sores Early Pregnancy Sign

Summary: Canker sores, also known as mouth ulcers, are a common occurrence during early pregnancy. They can be painful and uncomfortable, but are typically not a cause for concern. In this article, we will discuss the causes, symptoms, and treatments for canker sores during early pregnancy.

1. What causes canker sores during early pregnancy?

Canker sores are usually caused by stress, injury to the mouth, or certain foods and medications. During early pregnancy, hormonal changes can also contribute to the development of canker sores. It is believed that the increase in hormones such as estrogen and progesterone can cause changes in the mucous membranes of the mouth, making them more susceptible to irritation and injury.

In addition, immune system changes during pregnancy may play a role in the development of canker sores. The body’s immune system is designed to protect against harmful bacteria and viruses, but during pregnancy, the immune system is suppressed to prevent rejection of the developing fetus. This may make pregnant women more vulnerable to infections and other conditions, including canker sores.

Finally, nutritional deficiencies are another possible cause of canker sores during early pregnancy. Certain nutrients, such as iron, folate, and vitamin B12, are essential for healthy cell growth and function. Deficiencies in these nutrients can lead to oral health problems, including canker sores.

2. What are the symptoms of canker sores during early pregnancy?

The primary symptom of canker sores is pain or discomfort in the mouth. The ulcers usually appear as small, white or yellow bumps on the inside of the cheeks, lips, tongue, or roof of the mouth. They may be surrounded by a red, inflamed area, and can make it difficult to eat or speak.

While canker sores are generally not a serious condition, they can sometimes be mistaken for other oral health problems, such as cold sores or thrush. Cold sores, also known as fever blisters, are caused by the herpes simplex virus and are typically contagious. Thrush is a fungal infection that can develop in the mouth or throat and is characterized by white, creamy patches on the tongue and other parts of the mouth.

If you experience any unusual symptoms in addition to canker sores during early pregnancy, it is important to consult your healthcare provider for an accurate diagnosis and treatment plan.

3. How can canker sores be treated during early pregnancy?

Most cases of canker sores can be treated at home with over-the-counter remedies or natural remedies.

Some effective treatments for canker sores include:

– Oral analgesics (pain relievers) such as ibuprofen or acetaminophen

– Mouth rinses containing benzocaine or hydrogen peroxide

– Over-the-counter topical ointments or gels containing hydrocortisone or lidocaine

– Natural remedies such as aloe vera gel, honey, or chamomile tea

If you have frequent or severe canker sores during pregnancy, your healthcare provider may recommend prescription medications to help manage your symptoms. These may include steroid creams or mouthwashes, antiviral medications, or immune system modifiers.

4. How can canker sores be prevented during early pregnancy?

While canker sores cannot always be prevented, there are some steps you can take to reduce your risk of developing them. These include:

– Avoiding foods and drinks that may irritate the mouth, such as spicy or acidic foods

– Using a soft-bristled toothbrush and practicing good oral hygiene habits

– Managing stress through relaxation techniques like yoga or meditation

– Maintaining a healthy, balanced diet and taking vitamin supplements as needed

5. When should you see a healthcare provider for canker sores during early pregnancy?

Most cases of canker sores will resolve on their own within a week or two with proper care and treatment. However, in some cases, canker sores may be a sign of an underlying health condition, such as anemia, celiac disease, or a weakened immune system.

If your canker sores are severe, frequently recurring, or accompanied by other symptoms such as fever or difficulty swallowing, it is important to consult your healthcare provider for further evaluation. Your healthcare provider may perform tests to rule out other conditions or recommend additional treatments to manage your symptoms.


Canker sores are a common condition during early pregnancy, but they can be uncomfortable and painful. Hormonal changes, immune system changes, and nutritional deficiencies are all possible causes of canker sores during pregnancy. Treatment options include over-the-counter remedies, prescription medications, and natural remedies. Taking steps to prevent canker sores, such as practicing good oral hygiene and managing stress, can also help reduce your risk of developing them. If you experience severe or frequent canker sores during pregnancy, consult your healthcare provider for an accurate diagnosis and treatment plan.
