Breastfeeding is a natural and essential practice that has been embraced by cultures worldwide for centuries. It offers a plethora of benefits to both mothers and infants, ranging from optimal nutrition and immune system support to fostering a deep emotional connection between mother and child. 

However, over the years, misconceptions have arisen regarding the impact of breastfeeding on dental health, particularly concerning the development of malaligned teeth. In this blog, we aim to debunk this myth and shed light on the facts surrounding breastfeeding and its influence on teeth alignment.

Understanding Malaligned Teeth

Malaligned teeth, commonly referred to as “crooked” or “misaligned” teeth, occur when there is a deviation from the normal alignment of the teeth within the dental arch. This condition can manifest as overbites, underbites, crowding, or spacing issues. Malocclusions, as they are professionally known, can result from a combination of genetic factors, environmental influences, and certain habits during childhood.

The Breastfeeding Myth

The misconception that breastfeeding causes malaligned teeth has led to concerns among parents and caregivers. The belief stems from the notion that the act of breastfeeding may exert pressure on the baby’s developing jaw and teeth, leading to misalignment. 

However, it is essential to differentiate between breastfeeding and other oral habits, such as thumb-sucking or prolonged use of pacifiers, which have been associated with malocclusions.

The Role of Genetics and Oral Habits

Genetics plays a significant role in the development of a child’s teeth and jaw structure. If one or both parents have malocclusions, there is a higher likelihood that the child may inherit similar dental traits. Additionally, certain oral habits, such as thumb-sucking or using pacifiers extensively, can indeed impact dental alignment over time.

It’s important to emphasize that breastfeeding itself, when done correctly, is not a causative factor for malaligned teeth. Instead, it is other oral habits or hereditary factors that may contribute to dental misalignments.

Positive Impacts of Breastfeeding on Dental Health

Contrary to the myth, breastfeeding can have positive effects on a child’s dental health. Some of these benefits include:

  1. Jaw Development: The natural sucking motion during breastfeeding promotes the proper development of the jaw and oral muscles. This can contribute to better jaw alignment and a reduced risk of certain malocclusions.
  2. Nutritional Benefits: Breast milk provides essential nutrients that support overall health, including dental health. The vitamins and minerals present in breast milk contribute to the development of strong and healthy teeth.
  3. Reduced Risk of Baby Bottle Tooth Decay: Breastfeeding reduces the likelihood of prolonged exposure to sugary liquids, like formula or juice, which can lead to baby bottle tooth decay.

Promoting Good Oral Habits

While breastfeeding itself does not cause malaligned teeth, it is essential for parents and caregivers to be mindful of other oral habits that may impact dental development. Here are some tips to promote good oral habits in children:

  1. Proper Latch and Positioning: Ensuring a proper latch and positioning during breastfeeding can minimize potential issues related to jaw development.
  2. Limiting Pacifier Use: If your child uses a pacifier, consider limiting its use after the age of two or three to prevent potential dental problems.
  3. Addressing Thumb-Sucking: If your child develops a habit of thumb-sucking, try to gently discourage it as they get older to avoid dental misalignments.
  4. Regular Dental Check-ups: Introduce your child to regular dental check-ups from an early age. A pediatric dentist can monitor their oral health and provide guidance on proper dental care.


Breastfeeding is a beautiful and natural process that offers numerous benefits to both mother and child. It is not a direct cause of malaligned teeth. Rather, dental misalignments may be influenced by genetics and other oral habits, such as thumb-sucking or prolonged pacifier use.

Parents can feel confident in the knowledge that breastfeeding is a positive influence on their child’s dental health. By encouraging proper latch and positioning during breastfeeding, limiting pacifier use, and addressing thumb-sucking when necessary, parents can promote good oral habits and support their child’s overall dental development.

As always, consult with a pediatric dentist if you have specific concerns or questions about your child’s dental health. Embracing the many advantages of breastfeeding while being attentive to oral hygiene practices will set the stage for a lifetime of healthy smiles and well-being.
