Baby Bottle Tooth Decay, what is it?
Baby bottle tooth decay, also called nursing bottle caries or early childhood caries, occurs when a baby’s teeth are exposed to sugary liquids for prolonged periods. This often happens when infants are put to bed with a bottle, use a bottle as a pacifier, or drink from a bottle or sippy cup throughout the day. When these sugary drinks remain in the mouth—especially during sleep—they create the perfect conditions for bacteria to grow. The bacteria consume the sugar and produce acid, which erodes tooth enamel and leads to decay.
Should I be concerned about Baby bottle tooth decay?
A lot of parents wonder, “Why worry about baby teeth if they’re going to fall out anyway?” While it’s true that baby teeth are temporary, they play a crucial role in a child’s early development. Healthy baby teeth help children chew food properly, develop clear speech, and maintain the right spacing for their permanent teeth. If decay leads to early tooth loss, nearby teeth can shift out of place, which may cause alignment issues for adult teeth later on. Additionally, poor oral health in early childhood can interfere with eating, speaking, and overall well-being.
How to identify signs of baby bottle tooth decay
Early signs of enamel damage in infants often appear as white spots on the front teeth. If not treated, these spots can darken to brown or black as the decay progresses. The upper front teeth are usually affected first, but decay can spread to other teeth as well.
Causes of baby bottle tooth decay
- Drinks that are Sugary: Formula, milk, juice, and sweetened water can lead to tooth decay when offered frequently in bottles or sippy cups.
- Saliva Sharing: Cavity-causing bacteria can spread by sharing utensils or putting a baby’s pacifier in your mouth.
- Bedtime Bottles: Giving a baby a bottle at bedtime lets sugar linger on their teeth overnight, increasing the risk of decay.
- Extended Bottle or Sippy Cup Use: Letting a child carry a bottle or cup around all day means their teeth are exposed to sugar more often.
- Inadequate Oral Care: Skipping regular cleaning of your baby’s gums and teeth allows harmful bacteria to grow.
Tips to prevent baby bottle tooth decay
Healthy smiles start with healthy habits. Here’s how you can protect your child’s teeth from decay:
- Avoid Saliva Sharing: Don’t share feeding utensils or clean pacifiers with your mouth—this spreads cavity-causing bacteria.
- Limit Bottle Contents: Only use bottles for formula, breast milk, or milk. Avoid filling them with juice, sugar water, or soda. The American Academy of Pediatrics advises no juice for infants under 6 months and no more than 6 ounces per day for older children.
- Keep Pacifiers Clean: Always use a clean pacifier—never dip it in sugar or honey.
- Skip Bedtime Bottles: Don’t put your baby to sleep with a bottle of milk or juice; sugars can coat teeth overnight and cause decay.
- Use Bottles Only at Mealtimes: Limit bottle use to meals to reduce sugar exposure from prolonged sipping.
- Clean Gums and Teeth Early: Gently wipe your baby’s gums after each feeding. Once teeth appear, brush twice a day with a child-sized toothbrush and a smear of fluoride toothpaste.
- Start Flossing: When all baby teeth are in, begin flossing to remove plaque between teeth.
- Encourage Healthy Eating: Cut back on sugary snacks and drinks in your child’s diet.
- Schedule a Dental Visit: Book your child’s first dental checkup by their first birthday to help build lifelong oral health habits.

How to Break the habit and help your child move away from baby bottles
It’s not too late to build better oral health habits. If your child goes to sleep with a bottle or regularly sips sweetened drinks, try gradually weaning them off. Over 2 to 3 weeks, dilute the sugary liquid with more water each day until the bottle contains only water.
