🍼 Putting a baby to sleep with a bottle may seem comforting, but it’s one of the most common causes of early tooth decay in infants — medically known as Baby Bottle Caries or Nursing Bottle Caries. It occurs when liquids like milk, formula, or juice stay in contact with baby teeth for long periods, especially during sleep.
During sleep, saliva flow drops, reducing the mouth’s natural cleansing ability. The sugars in milk or juice then feed oral bacteria, which release acids that attack the enamel. Over time, this leads to rapid and severe decay — typically seen on the upper front teeth, spreading to molars if untreated.
Dentists often identify this pattern of decay by its characteristic brown or black spots near the gum line. It can cause pain, feeding difficulties, and infection, affecting speech and the alignment of permanent teeth later in life. Unfortunately, many parents only notice it once visible damage has already occurred.
To prevent it, experts recommend: avoid letting babies sleep with bottles containing anything other than water, wipe gums with a clean cloth after feeding, and start gentle brushing once the first tooth erupts. Early dental visits — ideally by age one — help detect any early signs and guide parents toward lifelong oral health habits.
