Early Childhood Caries (Baby Bottle Tooth Decay)

Early childhood caries, also known as baby bottle caries, baby bottle tooth decay, and bottle rot, is a syndrome characterized by severe decay in the teeth of infants or young children. Early childhood caries (ECC) is a very common bacterial infection. Its prevalence is epidemic; in the US its rate is highest in minority and rural populations, at times infecting over 70% of the children. A large body of scientific evidence indicates that ECC is an infectious and transmissible disease, with Streptococcus mutans the primary microbiological agent in the disease. The disease process begins with the transmission of the bacteria to the child, usually from the primary caretaker. Caretakers with untreated dental disease present a very high risk to their children.

What causes Baby Bottle Tooth Decay?

Baby Bottle Tooth Decay most often occurs in the upper front teeth, but other teeth may also be affected.
 
There are many factors which can cause tooth decay. One common cause is the frequent, prolonged exposure of the baby’s teeth to drinks that contain sugar. Tooth decay can occur when the baby is put to bed with a bottle, or when a bottle is used as a pacifier for a fussy baby.
Tooth decay is a disease that can begin with cavity-causing bacteria being passed from the mother (or primary caregiver) to the infant. These bacteria are passed through the saliva. When the mother puts the baby’s feeding spoon in her mouth, or cleans a pacifier in her mouth, the bacteria can be passed to the baby.
If your infant or toddler does not receive an adequate amount of fluoride, they may also have an increased risk for tooth decay. The good news is that decay is preventable.

Preventing Baby Bottle Tooth Decay

Never allow a child to fall asleep with a bottle containing milk, formula, juice or other sweetened liquids. Clean and massage the baby's gums to help establish healthy teeth and to aid in teething. Wrap a moistened gauze square or washcloth around the finger and gently massage the gums and gingival tissues. This should be done after every feeding.

 

Plaque removal activities should begin upon eruption of the first baby tooth. When brushing a child's teeth, use a soft toothbrush and water. If you are considering using toothpaste before your child's second birthday, ask your dentist first. Parents should first bring their child to the dentist when the child is between 6 and 12 months old.
