How Does Breastfeeding Affect my Child’s Teeth?



Breastfeeding has been lauded for its numerous health benefits for both infants and mothers - and rightly so! However, one persistent myth that has circulated is the notion that breast milk can cause cavities in babies' teeth. In this blog post, I'll debunk this misconception and delve into the importance of breastfeeding for dental hygiene, supported by scientific evidence and expert recommendations.


Debunking the Myth


From an evolutionary perspective, it's illogical to think that breast milk, a natural and essential source of nutrition for infants, would harm their dental health. Contrary to popular belief, studies have consistently shown that breastfed children are less likely to suffer from tooth decay or dental caries compared to those who are bottle fed. One such study, conducted by Vieira et al. (2021), found that breastfed infants exhibited lower rates of cavities. This suggests that breast milk itself does not contribute to tooth decay. Breastfeeding not only provides vital nutrients but also promotes optimal jaw and tooth development, reducing the risk of malocclusion and other dental issues.


The Evidence

Numerous studies support the idea that breastfed babies experience better dental outcomes. According to research, the longer a child is breastfed, the greater the reduction in the risk of dental problems. Additionally, breastfeeding is associated with a lower likelihood of tooth discoloration caused by excess fluoride, a common concern associated with artificial feeding methods.


Recent empirical research corroborates these findings, emphasizing the positive impact of breastfeeding on oral health. For instance, a study by Hwang et al. (2019) observed a significant association between breastfeeding duration and a reduced risk of dental caries in children. Similarly, a systematic review conducted by Azevedo et al. (2018) found compelling evidence linking breastfeeding to improved dental development and a lower prevalence of malocclusion.


Moreover, a longitudinal study by Peres et al. (2020) demonstrated that longer breastfeeding duration was associated with a lower risk of dental caries in primary teeth among Brazilian children. These findings underscore the importance of breastfeeding in promoting optimal oral health outcomes.


Additionally, a recent meta-analysis by Li et al. (2021) synthesized data from multiple studies and concluded that breastfeeding was inversely associated with the risk of early childhood caries. This comprehensive analysis further strengthens the evidence supporting the protective effects of breastfeeding against dental caries.


Collectively, these empirical studies provide robust evidence supporting the positive impact of breastfeeding on dental health outcomes, including reduced risk of dental caries and malocclusion. As such, promoting breastfeeding not only benefits infant nutrition and overall health but also contributes to better oral hygiene and dental development.



The Importance of Dental Hygiene


While breastfeeding itself does not cause cavities, it's essential for parents to prioritize good dental hygiene practices for their babies from the moment their first tooth emerges. Regardless of feeding method, proper oral care is crucial for maintaining healthy teeth and gums. The National Health Service (NHS) offers valuable, up-to-date advice on dental care for infants and children, emphasizing the importance of early intervention and regular check-ups.


Practical Tips for Dental Hygiene: Here are some practical tips for maintaining good dental hygiene in breastfed babies:


  1. Begin oral care early: As soon as your baby's first tooth emerges, start gently cleaning it with a soft infant toothbrush and water.

  2. Limit sugary substances: Be mindful of introducing sugary foods or drinks to your baby, toddler or child's diet, as these can contribute to tooth decay. Stick to nutritious, tooth-friendly snacks and drinks, such as water or breast milk.

  3. Schedule dental check-ups: Regular visits to the dentist are essential for monitoring your baby's dental health and addressing any concerns early on. Aim to schedule your baby's first dental appointment within six months of their first tooth eruption or by their first birthday.

In conclusion, breast milk does not cause cavities in babies' teeth. On the contrary, breastfeeding offers numerous benefits for dental health, including promoting optimal jaw and tooth development and reducing the risk of dental caries. While more research is needed to fully understand the interplay between breastfeeding, diet, and dental health, current evidence suggests that breastfeeding is beneficial for oral health. By practicing good dental hygiene from the start and seeking regular dental care, parents can help ensure their breastfed babies enjoy healthy smiles for years to come.
