Baby bottle decay is a common word, not a verdict on your parenting.

In kid words

"Sugar drinks that nap on your teeth too long can leave tiny owies called cavities, so we rinse with water and brush before bed." Say it in the same easy voice you use for wash your hands before dinner, not as a warning. Kids pick up on tone fast, and this one is meant to sound as ordinary as any other bedtime step.

The parent version

Baby bottle decay, sometimes called early childhood caries, is the mainstream term for cavities that show up early, often on the upper front teeth, in babies and toddlers. It is generally linked to prolonged or repeated exposure to sugary liquids, including formula, milk and juice, especially when a bottle or sippy cup is carried to bed or sipped slowly across a long stretch of the day.

The detail parents tend to miss is that frequency matters more than the drink itself. A cup finished at the table asks far less of a tooth than the same drink nursed for an hour or left within reach overnight, since sugar sitting against enamel for long periods is what gets the attention in mainstream guidance. Water between meals and a brush after the last drink of the day cover most of the everyday picture. Anything beyond that, including what a specific habit in your own house calls for, is worth a conversation, so ask your pediatric dentist.

Where you might hear it at our office

This is exactly the territory first-birthday-visit coaching covers. Bottle habits, sippy cup routines and bedtime feeds come up as an ordinary part of the conversation, not a lecture, because infant dental care exists to catch these patterns while they are still easy to adjust, judgment-free. Nobody is graded on how the last few months went.

If another word from a visit sent you looking things up, the rest of the dictionary is built the same way this entry is, in kid words and in plain parent terms.
