Baby Bottle Tooth Decay ( B B T D ) is the term adopted in 1986 by the Healthy Mothers Healthy Babies Oral Health Coalition to describe the decay of primary maxillary incisors that occurs due to prolonged bottle feeding in young children.

BBTD is commonly found in children who are given a bottle of milk or sugared liquid to nurse during the day or when the baby is put to bed.The position of the tongue is such that it causes the liquid to be in constant contact with the maxillary incisors thus encouraging bacterial growth. Generally the incisors of the upper jaw get affected but if proper measures are not taken than whole upper jaw gets affected.

BBTD occurs extensively in the American, Indian & Alska native
communities.The high incidence of of BBTD in Alaskan children is due to continued use of bottle.
