Canker Sores During Pregnancy • Canker Sores Early Pregnancy Symptom

Summary: Canker sores can be a frustrating and painful problem for anyone, but they can be especially bothersome during pregnancy. These shallow ulcers that form inside the mouth can make it difficult to eat, talk, or even swallow, and they may occur more frequently in pregnant women due to hormonal changes and other factors. Understanding the causes, symptoms, and treatment options for canker sores during pregnancy can help expectant mothers find relief and stay healthy throughout this exciting time.

1. What Causes Canker Sores During Pregnancy?

While the exact causes of canker sores are not fully understood, there are several factors that may play a role in their development, especially during pregnancy. Hormonal changes can disrupt the delicate balance of bacteria in the mouth and cause the immune system to become more sensitive to certain triggers, leading to the formation of canker sores. Nutritional deficiencies, stress, and poor oral hygiene may also contribute to their development.

Symptoms of canker sores may include a burning or tingling sensation in the affected area, as well as small, round, or oval-shaped sores inside the mouth. These ulcers may be white or gray in color, with a red border, and may be accompanied by swollen or tender gums.

Treatment for canker sores may involve over-the-counter pain relievers or topical treatments like mouthwashes or gels. In some cases, prescription medications or dietary supplements may be needed to address underlying factors like infection or nutritional deficiencies.

2. Complications and Risks of Canker Sores During Pregnancy

While canker sores are usually harmless and resolve on their own within a week or two, they can still pose some risks and complications during pregnancy. For example, they may make it difficult or painful to eat, leading to weight loss or malnutrition. They may also increase the risk of infection or inflammation in the mouth and throat, or cause discomfort or irritation during dental exams.

Some studies have also suggested a possible link between canker sores and certain pregnancy complications, such as preterm birth or low birth weight. However, more research is needed to confirm this association and determine the underlying mechanisms.

If you experience frequent or severe canker sores during pregnancy, it is important to discuss your symptoms with your healthcare provider and receive appropriate treatment and monitoring.

3. Self-Care and Home Remedies for Canker Sores During Pregnancy

Fortunately, there are several simple self-care measures and home remedies that can help alleviate the pain and discomfort of canker sores during pregnancy. For example, rinsing your mouth with warm salt water several times a day can help reduce inflammation, promote healing, and prevent infection. Applying a small amount of milk of magnesia or baking soda paste directly to the sore may also help soothe the area and promote healing.

Eating a balanced diet rich in vitamins and minerals, especially vitamin B12, folate, and iron, can also help prevent and reduce the frequency and severity of canker sores. Avoiding spicy or acidic foods, as well as alcohol and tobacco, can also help reduce irritation and inflammation in the mouth.

Maintaining good oral hygiene habits, such as brushing and flossing regularly and using a soft-bristled brush and mild toothpaste, can also help reduce the risk of canker sores and other oral health problems during pregnancy.

4. When to Seek Medical Attention for Canker Sores During Pregnancy

While most canker sores will resolve on their own within a week or two, there are some cases where medical attention may be needed. For example, if you experience severe or persistent pain, bleeding, or pus around the sore, it may indicate an infection or other complication that requires treatment with antibiotics or other medications.

If you develop a high fever, swelling in the face or neck, or difficulty breathing or swallowing, it may indicate a more serious condition like oral cancer or Stevens-Johnson syndrome. These conditions are rare but can be life-threatening if left untreated, so it is important to seek medical attention immediately if you experience these symptoms.

In general, it is always a good idea to discuss any new or unusual symptoms with your healthcare provider during pregnancy, as they can help determine the most appropriate course of action and ensure that you and your baby stay healthy and happy.


Canker sores can be a painful and frustrating problem for anyone, but they can be especially problematic during pregnancy. While the exact causes and mechanisms of canker sores are not fully understood, there are many factors that may contribute to their development, including hormonal changes, nutritional deficiencies, stress, and poor oral hygiene. Understanding the symptoms, treatment, and self-care options for canker sores during pregnancy can help expectant mothers find relief and avoid complications, and ensure a healthy and enjoyable pregnancy.
