Understanding Baby Bottle Decay: Causes, Risks & Prevention for Parents
Baby bottle tooth decay (also known as early childhood caries) is a common yet serious condition that affects infants and toddlers. It happens when baby teeth are exposed to sugary drinks for extended periods—especially at night. In this post, we’ll cover the causes, warning signs, and simple steps parents can take to protect their little one’s smile.
See the Canadian Dental Association’s resources on bottle feeding and decay.
What Causes Baby Bottle Tooth Decay?
🍼 Putting your baby to bed with a bottle of:
- Milk
- Formula
- Juice
- Sweetened liquids
These sugars feed the bacteria in the mouth, producing acid that attacks tooth enamel—especially on the upper front teeth.
👶 Frequent or prolonged bottle use during naps or bedtime is the main cause.
Signs of Early Childhood Tooth Decay
🔹 White spots on the teeth (early warning)
🔹 Brown or black spots
🔹 Bad breath
🔹 Pain, swelling, or irritability when eating
🔹 Difficulty sleeping
If left untreated, baby bottle decay can lead to:
- Infection
- Premature tooth loss
- Problems with speech, nutrition, and adult tooth alignment

How to Prevent Baby Bottle Tooth Decay
✅ Clean the mouth after each feeding
Even before teeth appear, wipe gums with a clean, damp cloth.
✅ Avoid bottles at bedtime
If your baby needs comfort, offer plain water only at night.
✅ Never dip pacifiers in sugar or honey
This old-fashioned habit is harmful and increases cavity risk.
✅ Limit juice and sweet drinks
Follow Health Canada guidelines: avoid juice before age 1; limit to 4 oz after age 1.
✅ Brush baby teeth twice daily
Use a soft brush and fluoride toothpaste once teeth erupt.
