Bottle rot teeth
Bottle-related tooth decay is early childhood caries caused by repeated sugar exposure, especially when a child sleeps with milk or sweet drinks.
The short answer
Bottle-related tooth decay is early childhood caries that develops when teeth are repeatedly exposed to milk or other fermentable carbohydrates, especially during sleep. Bacteria in dental plaque use these sugars to produce acids that dissolve enamel and dentine.
What can early bottle-related tooth decay look like?
Early lesions may look like chalky white bands near the gumline, followed by yellow, brown, or broken areas as mineral loss progresses. The upper front teeth are often affected because liquid pools around them, while the lower front teeth may be partly protected by the tongue and saliva.
How can you prevent decay from bedtime bottles?
Do not put a child to sleep with a bottle containing milk, juice, or another sweet drink, and begin brushing erupted teeth with a small amount of fluoride toothpaste. Offer water between meals, avoid frequent sugary drinks, and arrange an early dental examination when marks or cavities appear.
When should a child with possible decay see a dentist?
See a dentist promptly for white or brown patches, visible holes, toothache, sensitivity, swelling, fever, or difficulty eating. Facial swelling, spreading infection, or trouble swallowing requires urgent care.
What should you ask about treating your child's decay?
Ask which teeth have early decay, whether fluoride varnish or a filling is appropriate, and how brushing should change with your child's age. Ask how to replace the bedtime bottle routine and how often follow-up is needed.
Frequently asked questions
Can baby teeth really get cavities?
Yes. Primary teeth contain enamel and dentine that can be damaged by acid from plaque.
What should a child drink at bedtime?
Water is the tooth-friendly choice once teeth have erupted; ask the child's dental team about feeding needs.
Can early decay be repaired without a filling?
Some early non-cavitated lesions can be managed with prevention and professional treatments, while a cavity may need restoration.
