Dental problems and cavities during breastfeeding: How moms are affected

From hormonal changes to the physical demands of breastfeeding, mothers may experience an increased risk of dental problems such as cavities, gum disease, and enamel erosion.
Breastfeeding is a beautiful and natural way to nourish your baby, offering numerous health benefits for both mother and child.
However, while breastfeeding provides essential nutrients and bonding time, it can also affect a mother's dental health in various ways.
From hormonal changes to the physical demands of breastfeeding, mothers may experience an increased risk of dental problems such as cavities, gum disease, and enamel erosion.
1. Hormonal changes and their impact on oral health
One of the most significant factors affecting a mother's dental health during breastfeeding is hormonal changes.
After childbirth, your body undergoes many changes that can influence your gums, teeth, and overall oral health:
- increased risk of gum disease: hormonal fluctuations during breastfeeding can make gums more sensitive, inflamed, and prone to infection. This is particularly true if a mother has a history of gingivitis or periodontal disease. The hormone progesterone, which is elevated during pregnancy and breastfeeding, can increase the inflammatory response of the gums to plaque, making them more likely to bleed, swell, and cause discomfort.
- dry mouth: many mothers experience dry mouth (also known as xerostomia) while breastfeeding. Hormonal shifts can reduce saliva production, leading to a dry mouth. Saliva is essential for neutralizing acids and washing away food particles and bacteria. A dry mouth can contribute to a higher risk of tooth decay and gum disease, as there is less natural protection against harmful bacteria.
2. Breastfeeding and cavities
Breastfeeding itself is not directly responsible for cavities, but it can contribute to the development of cavities in mothers under certain conditions:
- frequent snacking and sugary cravings: many breastfeeding mothers experience intense cravings or increased hunger while nursing. This can lead to frequent snacking on sugary foods or drinks. Frequent sugar consumption, without proper oral hygiene afterwards, can lead to an increased risk of cavities. The sugar in foods and drinks can feed harmful bacteria in the mouth, which produce acids that erode tooth enamel and cause tooth decay.
- acidic beverages: some breastfeeding mothers may turn to acidic drinks such as fruit juices, citrus-based beverages, or sodas to help stay hydrated or alleviate nausea. The acidity of these drinks can erode tooth enamel, weakening teeth and making them more vulnerable to cavities. This is particularly concerning if the drinks are consumed throughout the day or without proper oral care afterwards.
3. Dental erosion and enamel wear
The physical act of breastfeeding can sometimes contribute to dental erosion for mothers, though this is less common. However, it is important to be mindful of the following:
- acidic foods and beverages: some mothers may indulge in acidic foods or drinks as a way to combat nausea or fatigue during breastfeeding. Over time, consuming these beverages without proper rinsing or brushing can lead to the erosion of tooth enamel. This makes teeth more sensitive and prone to decay.
- dehydration and lack of proper hydration: breastfeeding mothers are more prone to dehydration, which can negatively affect their oral health. Dehydration can lead to a dry mouth, which, as mentioned, reduces saliva flow and increases the risk of cavities, gum disease, and bad breath.
4. Maintaining oral health while breastfeeding
Fortunately, there are several steps mothers can take to protect their dental health while breastfeeding:
- Maintain a balanced diet: while breastfeeding can increase appetite, try to focus on healthy, nutrient-rich foods rather than sugary snacks. Whole grains, vegetables, fruits, lean proteins, and dairy products help support overall health, including oral health. Calcium-rich foods, such as milk, cheese, and leafy greens, are especially important for maintaining strong teeth.
- Stay hydrated: drinking plenty of water throughout the day can help prevent dry mouth, promote saliva production, and rinse away food particles and bacteria. Carry a water bottle with you and take frequent sips, especially if you are breastfeeding or spending time in a warm environment.
- Good oral hygiene practices: brush your teeth at least twice a day with fluoride toothpaste and floss daily to remove plaque from between your teeth. After breastfeeding, if you are unable to brush, rinse your mouth with water to wash away milk residues or acidic foods. This will help reduce the risk of cavities and gum issues.
- Use a moisturising mouth rinse: if you are experiencing dry mouth, consider using a mouth rinse designed for dry mouth relief. These rinses help keep your mouth moist and can provide relief from discomfort while preventing bacteria buildup that can lead to dental problems.
- Avoid acidic or sugary drinks: while it can be tempting to reach for sugary or acidic drinks for energy or hydration, try to avoid these beverages when possible. Opt for water, herbal teas, or milk instead. If you do consume acidic or sugary drinks, rinse your mouth afterwards with water to reduce their effects on your teeth.
- Regular dental visits: it is essential to continue regular dental check-ups while breastfeeding. Inform your dentist about any changes in your oral health, such as increased sensitivity or gum inflammation. Early detection of issues like gum disease or cavities can help prevent more serious dental problems later.
5. Dental sensitivity and tooth pain
Breastfeeding can sometimes lead to increased tooth sensitivity, particularly if you are dealing with hormonal changes, dry mouth, or cavities. Sensitivity can occur when eating or drinking hot, cold, or sweet foods. To manage this, consider using a toothpaste designed for sensitive teeth.
Additionally, if you experience persistent tooth pain or discomfort, it's important to see your dentist to rule out cavities or other dental issues.
While breastfeeding is a beautiful and beneficial experience, it can present some challenges to a mother's dental health.
Hormonal changes, frequent snacking, dry mouth, and the consumption of acidic or sugary foods can increase the risk of dental problems such as cavities and gum disease.
By maintaining a balanced diet, practising good oral hygiene, staying hydrated, and attending regular dental check-ups, mothers can protect their oral health during the breastfeeding period.
Taking care of your teeth and gums not only helps ensure your own well-being but also sets a positive example for your little ones as they grow and develop their own healthy habits.
