Breastfeeding and Oral Health: What Your Family Dentist Should Tell You

Breastfeeding and Oral Health: What Your Family Dentist Should Tell You

When having a baby there are a lot of important decisions to be made. One of the biggest is whether or not to breastfeed your child. While it ultimately remains a personal decision for any new mother, there are some lesser-known benefits to the most natural form of feeding that are important to be aware of, so that you can guarantee you and your family dentist are doing what is best for your little one.

In addition to the incredible antibodies contained in breast milk that aid in improving an infant’s overall well-being, breastfeeding has the added advantage of specifically enhancing the newborn’s oral health. Specifically, it can prevent both malocclusion and childhood tooth decay.

Malocclusion is a condition where the facial bones and muscles are ill-formed resulting in an incorrect positioning of the face structure which causes ongoing problems with the upper and lower jaw and teeth, especially when biting or chewing. Bottle-fed babies are more susceptible to this due to the difference between a baby bottle and a woman’s natural nipple. The mother’s nipple is the only structure able to perfectly adapt to the baby’s mouth and contribute to the development of the facial structures such as bone and muscles.

The benefits continue during the actual feeding process with the sucking motion being different between the two options. Breastfeeding requires more force from the baby’s mouth which promotes greater muscle activity and therefore helps with the muscle development. The amount of time dedicated to breast feeding before switching to the bottle can also determine if a child is at risk of experiencing malocclusion.

A baby developing teeth can often be an indication that it is time to switch to the bottle and having being breastfed increases the chances that their first set of teeth will be in good health, because the suction created when breastfeeding generates more saliva which helps to protect the teeth from decay. Babies who have been breastfed for up to one year of age have less risk of contracting tooth decay as they grow up.

Benefits of Breast Milk for Oral Health

Reduced Risk of Cavities:

Breast milk provides a natural advantage in the fight against cavities. Unlike formulas and other sugary drinks, breast milk contains significantly less sugar, reducing the fuel source for bacteria that cause tooth decay. Additionally, breast milk is rich in protective factors like:

  • Lactoferrin: This protein binds to iron, limiting its availability for cavity-causing bacteria.
  • Lysozyme: This enzyme breaks down the cell walls of bacteria, inhibiting their growth and preventing them from forming biofilms on teeth.
  • Secretory IgA: This antibody specifically targets bacteria associated with dental caries, further reducing the risk of tooth decay.

These unique components in breast milk act as a natural defense system, protecting your baby’s developing teeth from harmful bacteria and promoting a healthy oral environment.

How Breastfeeding Shapes a Healthy Jaw:

The sucking action involved in breastfeeding plays a crucial role in promoting your baby’s jaw development. This natural process offers numerous benefits, including:

  1. Stimulating Muscle Growth: The sucking motion strengthens the jaw muscles, masseter, and temporalis, which are responsible for chewing and jaw movement. As these muscles develop, they provide the necessary foundation for proper jaw function and future oral health.
  2. Encouraging Bone Formation: The force generated during sucking acts on the jawbone, stimulating its growth and shaping it into a healthy form. This process helps create the necessary space for teeth to erupt properly and contributes to a well-aligned bite.
  3. Aligning Teeth: The sucking action also guides the erupting teeth into their proper positions within the jawbone. This natural process helps to prevent malocclusions, such as overcrowding or misaligned teeth, which can lead to functional and aesthetic problems.
  4. Promoting Facial Development: The sucking involved in breastfeeding stimulates not only the jaw muscles but also the facial muscles and structures. This contributes to the overall development of the face, leading to a balanced and harmonious appearance.

By promoting jaw development, breastfeeding lays the foundation for a lifetime of good oral health. Strong jaw muscles, proper bone formation, and aligned teeth all contribute to efficient chewing, clear speech, and a healthy smile.

Tips for Maintaining Oral Health While Breastfeeding

Avoid Sharing Spoons:

While sharing a meal with your baby can be a heartwarming experience, sharing utensils like spoons can expose them to unwanted bacterial guests. The saliva present in your mouth naturally harbors a diverse range of bacteria, some of which can be harmful to your baby’s developing oral environment.

Here’s why avoiding sharing spoons with your baby is crucial for their oral health:

  1. Transferring Bacteria: When you share a spoon, bacteria present in your saliva can easily transfer to your baby’s mouth. This can include cavity-causing bacteria like Streptococcus mutans, which can colonize your baby’s teeth and increase the risk of tooth decay.
  2. Increased Cavity Risk: Babies have weaker tooth enamel compared to adults, making them more susceptible to cavities. Introducing harmful bacteria from your saliva can significantly increase their risk of developing dental caries.
  3. Protecting Your Baby’s Immune System: While babies have a developing immune system, it may not be strong enough to efficiently combat the influx of bacteria introduced through shared spoons. This can put them at risk of oral infections and other health problems.
  4. Establishing Healthy Habits: By avoiding sharing spoons early on, you help your baby develop healthy oral hygiene habits. This sets them on the right track for maintaining good oral health throughout their life.

Therefore, it is essential to use separate spoons for yourself and your baby during mealtimes. This simple practice plays a significant role in protecting your baby from harmful bacteria and promoting their oral health.

Scheduling Regular Dental Checkups:

Just like adults, babies benefit from regular dental checkups. These appointments offer valuable opportunities to:

  • Monitor Oral Health: Dentists can assess your baby’s oral development, check for any early signs of cavities or other problems, and ensure their teeth are erupting properly. This proactive approach allows for early detection and intervention, preventing potential complications down the road.
  • Address Potential Issues Early: Dental checks provide a platform for identifying and addressing any emerging oral health concerns promptly. Whether it’s tooth decay, gum disease, or oral habits like thumb sucking, early intervention can significantly improve the outcome and minimize the risk of future problems.
  • Establish a Dental Home: Scheduling regular appointments helps your baby become comfortable with the dentist’s office and build trust with the dental team. This familiarity fosters a positive association with dental care, making future visits less stressful and promoting lifelong oral health habits.
  • Receive Personalized Guidance: Dentists can provide valuable guidance and support to parents in caring for their baby’s oral health. They offer tips on brushing and flossing techniques, recommend appropriate oral hygiene products, and address any specific concerns or questions parents may have.
  • Promote Healthy Habits: Regular dental checkups serve as a reminder to parents about the importance of oral hygiene and early oral health interventions. This reinforces the need for consistent brushing, flossing, and a healthy diet, ensuring your baby develops strong and healthy teeth for years to come.

By scheduling regular dental checkups for your baby, you take an active role in safeguarding their oral health and building a foundation for a lifetime of healthy smiles.

Addressing Common Concerns About Breastfeeding and Oral Health

White and Brown Spots on Baby Teeth:

The appearance of white or brown spots on your baby’s teeth warrants immediate dental attention. While some may be harmless, others could indicate underlying dental concerns that require professional evaluation and treatment. Here’s why:

  1. Possible Causes: White spots could be early signs of tooth decay (enamel demineralization), enamel hypoplasia (defects in tooth development), or fluorosis (excess fluoride exposure). Brown spots, on the other hand, could be caused by dental stains, plaque buildup, or iron deficiency anemia.
  2. Early Detection is Key: Identifying the cause of these spots early on is crucial. Timely intervention can prevent further damage to the teeth and ensure proper treatment is initiated. Ignoring these spots could lead to cavities, tooth sensitivity, and more severe complications later.
  3. Addressing Parental Concerns: Seeing white or brown spots on your baby’s teeth can raise concerns for parents. Consulting with your dentist provides an opportunity to discuss these concerns, receive professional advice, and understand the best course of action for your baby’s unique case.
  4. Maintaining Oral Hygiene: Regardless of the cause, maintaining good oral hygiene practices like regular brushing and flossing is essential. This helps prevent further discoloration, promotes overall oral health, and sets your baby on the path to a healthy smile for life.

Remember, white or brown spots on baby teeth should not be ignored. Promptly seeking a dental evaluation ensures early diagnosis, appropriate treatment, and peace of mind for parents.

Bleeding Gums: May indicate gingivitis, requiring professional assessment.

Noticing bleeding gums in your baby can be alarming, especially during the early stages of their oral development. While the occasional bleed after brushing may not be a cause for immediate concern, persistent or excessive bleeding requires professional assessment. Here’s why:

  1. Potential Signs of Gingivitis: Bleeding gums often indicate the presence of gingivitis, an early stage of gum disease. Gingivitis is caused by plaque buildup and inflammation of the gums, which can lead to discomfort, tenderness, and even tooth loss if left untreated.
  2. Importance of Early Intervention: Early diagnosis and treatment of gingivitis are crucial. By addressing the issue promptly, your dentist can prevent the progression of gum disease, protect your baby’s teeth, and maintain their overall oral health.
  3. Possible Underlying Causes: In some cases, bleeding gums can be caused by other factors like teething, brushing too hard, or injuries to the gums. Identifying the specific cause is essential for providing appropriate treatment and preventing future occurrences.
  4. Dentist’s Expertise: Consulting your dentist allows for a thorough examination of your baby’s oral cavity. They can assess the severity of the bleeding, identify any underlying causes, and recommend the most effective course of treatment.
  5. Tailoring Oral Hygiene Practices: Your dentist can provide individualized advice on how to improve your baby’s oral hygiene practices. This may include modifications to brushing techniques, recommendations for appropriate toothpaste and toothbrushes, and dietary adjustments to promote healthy gums.

Remember, bleeding gums should not be taken lightly. Seeking professional dental evaluation ensures prompt diagnosis, and appropriate treatment, and promotes long-term oral health for your baby.

Collaborating with Your Dentist for Optimal Oral Health:


  • Timing is key: Start flossing your baby’s teeth once they have two teeth that touch each other.
  • Gentle technique: Use gentle, back-and-forth motions with a piece of floss.
  • Daily routine: Floss once daily, preferably before bedtime.

Regular Dental Checkups:

  • Early evaluation: Schedule your baby’s first dental checkup within six months of their first tooth eruption.
  • Routine monitoring: Continue with regular dental checkups every six months.
  • Early detection and intervention: These visits allow for early detection and treatment of any potential oral health concerns.

By incorporating these good oral hygiene habits into your baby’s daily routine, you are setting them on the path to a lifetime of healthy smiles. Remember, early intervention and preventative care are key to promoting your baby’s overall well-being and ensuring they develop strong, healthy teeth and gums.

Good oral hygiene habits are not just about having a healthy smile, but also about promoting good self-esteem and confidence. By teaching your baby good oral hygiene habits from a young age, you are giving them the gift of a lifetime of healthy smiles and overall well-being.
