Your toddler has cavities in their baby teeth. It might seem like a big deal — after all, those teeth are going to fall out anyway. But baby bottle tooth decay matters more than you might think.
Baby teeth hold space for adult teeth. If they're lost early because of decay, the adult teeth might come through in the wrong position. Your child could need orthodontic treatment later.
The good news? Baby bottle tooth decay is almost entirely preventable.
What Causes Baby Bottle Tooth Decay?
The name tells you a lot. Letting your baby or toddler fall asleep with a bottle — particularly one containing milk, formula, or fruit juice — is the main culprit. When a child sleeps with a bottle, the teeth are bathed in sugar for hours.
That sugar feeds bacteria in the mouth. The bacteria produce acid, and that acid attacks the teeth, causing decay.
It's not just bottles, though. Frequent breastfeeding through the night, sippy cups filled with sweet drinks, and even some medications can contribute to tooth decay in young children.
How to Prevent It
Never put your child to bed with a bottle. If they need something to drink at night, offer water only. Milk and juice contain sugars that sit on teeth and cause decay.
Start brushing as soon as the first tooth appears. Use a fluoride toothpaste — the amount should be no bigger than a grain of rice for babies.
Take the bottle away once your child has finished drinking. Don't let them walk around with a bottle or sippy cup all day.
When to Wean Off the Bottle
Most children can start using a cup from around six months and should be off bottles completely by their first birthday. The longer you wait, the harder it gets to make the switch.
If your child resists, try offering the cup first at mealtimes when they're hungry. Move to cup-only over a few weeks rather than stopping abruptly.
What If Decay Has Already Started?
See a dentist as soon as possible. Early decay can sometimes be stopped or reversed with better habits and fluoride treatment. More advanced decay might need a filling or, in severe cases, a baby tooth extraction.
Don't wait. The longer decay progresses, the more complicated the treatment becomes. And your child is watching and learning from how you handle it — show them that dental visits are nothing to fear.
