Potential Risks: Breastfeeding and Tooth Decay

While breast milk is considered the best form of infant nutrition, it does contain natural sugars. When a baby’s teeth are frequently exposed to milk, especially during prolonged nighttime feedings after tooth eruption, it may increase the risk of early childhood cavities — sometimes referred to as “baby bottle tooth decay” — even in breastfed infants.

To reduce this risk, it is important to avoid continuous overnight nursing once the baby’s teeth have emerged.

Oral Hygiene Tips for Breastfed Babies

Establishing good oral hygiene early is essential, even before the first tooth appears.

• Gently clean your baby’s gums with a soft, damp cloth after feedings.
• Once the first tooth erupts, use a soft-bristled infant toothbrush with plain water.
• Avoid toothpaste before age two unless recommended by a dental professional.
• If your baby falls asleep while nursing, try to clean their mouth before bedtime to remove any milk residue.

When to Visit a Dentist

It is recommended that your child sees a dentist by their first birthday or within six months of the first tooth erupting. Early dental visits allow professionals to monitor oral development and detect early signs of decay, such as white spots on the teeth. Prompt attention can prevent more serious issues later on.

Breastfeeding promotes healthy oral development, but it is equally important to adopt good hygiene practices early. Clean your baby’s gums regularly, minimise prolonged nighttime nursing after teething, and schedule timely dental visits to ensure a strong foundation for lifelong oral health.
