Why Baby Bottle Tooth Decay Happens—and How to Prevent It

As a parent, you're doing everything you can to keep your child healthy, but there’s one common dental issue that often flies under the radar: baby bottle tooth decay. At Dr. Sugar’s pediatric dental office in Paradise Valley, AZ, we regularly help families prevent and treat this entirely avoidable condition.

What Is Baby Bottle Tooth Decay?

Baby bottle tooth decay, also known as early childhood caries, is a type of cavity that affects infants and toddlers—most often in the upper front teeth. It usually occurs when a child frequently goes to sleep with a bottle or sippy cup containing milk, juice, or sweetened liquids.

The sugars from these drinks cling to your baby’s teeth overnight, feeding bacteria that produce acid. Over time, these acids break down tooth enamel, leading to decay—even in very young children.

What Causes It?

Here are some of the most common habits that lead to baby bottle tooth decay:

Falling asleep with a bottle filled with milk, formula, or juice

Frequent daytime sipping on sugary drinks

Dipping pacifiers in honey or sweet substances

Infrequent or delayed brushing

Delaying your child’s first dental visit

Why Baby Teeth Matter

Although baby teeth are temporary, they play an essential role in your child’s development. Healthy primary teeth:

Help children chew and eat properly

Aid in speech development

Hold space for adult teeth

When decay is left untreated, it can cause pain, infections, and difficulty eating or speaking. It may also affect how permanent teeth come in and contribute to long-term dental anxiety.

How to Prevent Baby Bottle Tooth Decay

The good news is that baby bottle tooth decay is largely preventable. Here’s what Dr. Sugar recommends for parents in Paradise Valley:

Offer only water in bottles or sippy cups at bedtime or naptime

Begin brushing with a soft toothbrush and a tiny smear of fluoride toothpaste as soon as the first tooth erupts

Clean your baby’s gums with a damp cloth after feedings—even before teeth appear

Avoid giving your child sugary drinks between meals

Never dip pacifiers in sweet liquids

Schedule your child’s first dental visit by age one or within six months of their first tooth
