Why Does My Baby’s Breath Smell?

Bad breath in babies is a common issue that can be easily treated with the correct diagnosis. New mothers struggle to evaluate the root cause, but treating the problem is more manageable once diagnosed. 

Infants and babies are cute and cuddly, but no one wants to go close to them if your baby stinks. Several reasons can develop bad baby breath. A few of them are discussed here:

1: Milk

Milk is the most common thing that babies consume. There can be circumstances when your baby consumes too much milk, and their stomach regurgitates it back into the mouth.

Keeping the baby in the correct position is necessary to help them digest the milk and avoid breathing smells. 

2: Sugar

Kids of younger age are fond of eating sugar candies, which can be a potential cause of lousy baby breath. Sugar consumption increases the bacterial growth in the mouth that feasts on sugar.

Sugar leftovers cause foul-smelling gases that add to bad breath. So, dentists and nutritionists also suggest giving low-sugar diets to kids. 

3: Toys

Babies have a habit of mouthing their toys, which can encourage the putrefying bacteria mouth, leading to lousy baby breath.

The saliva is transferred to the toys that develop a small odor and is transferred back to the baby’s mouth when they suck it again. 

At such a stage, parents need to be careful and attentive to prevent kids from taking toys to their mouths. It is a common oral hygiene practice that must be taken care of. 

4: Dry Mouth

In some cases, kids fail to have nose breathing, such as when having colds or allergies. Mouth breathing causes oral tissues to dry, a breeding ground for putrefying bacteria

Apart from milk, dry mouth, and sugar, there can be more possibilities that your baby has bad breath due to the following:

  • Tooth decay
  • Allergies
  • Infection
  • Gastroesophageal reflux
