Extended Breastfeeding Non-Risk #2: Dental Caries

Linda J. Smith, BSE, FACCE, IBCLC

The most important causes of Baby-Bottle Tooth Decay (BBTD) are
documented to be: (1) Enamel defects; (2) High carbohydrate intake in
the
infant's diet; (3) Oral hygiene of the mother and infant, especially
strap mutans; (4) Milk pooling in the baby's mouth from a dripping
bottle.

As of April 1992, all known references point back to three articles by
Kotlow, Brams, and Gardner. The authors present case reports of 9
babies,
only 7 of whom received no bottles. Recently, the lactose in milk has
been shown to cause decay when teeth are soaked in it.

This evidence does not establish that direct breastfeeding as a risk
factor in BBTD because:

In these 7 case reports, there was no mention of enamel defects,
carbohydrate intake, or bacterial milieu.

Human milk is protective against strep mutans.

Milk pooling does not occur during breastfeeding because the
breast does not release milk unless the infant is actually sucking and
swallowing. If human milk is provided by bottle, pooling could
occur. Bottle feeding is a risk factor; even bottle feeding of human
milk.

Case studies report on unusual situations; the reports are from
1977 and 1983. There have been no large-scale or epidemiological studies

on this phenomenon. If long-term, at-will nighttime breastfeeding
were a risk factor for BBTD, epidemiologic evidence would have
demonstrated this link.

Dr. David Johnson, DDS, pediatric dentist at Case Western Reserve
University, specialist on BBTD, said in January 1992 "It is a small
risk, rare and unusual. It's not enough to base a policy of 'no
breastfeeding past 12 months.' The advantages of breastfeeding past 12
months are absolutely overwhelming."

The position of the American Academy of Pediatric Dentistry (wean
by 12 months) was challenged by Ruth Lawrence, MD in Feb. 1993.
Dr. Lawrence sent many solid references on the documented risks of
early weaning. The AAPD position conflicts with AAP, DHHS,
WHO and other health policy documents.

NEW: P. R. Erickson at the University of Minnesota recently
published research that "concluded that human breast milk is not
cariogenic."


FACT: There is no published, valid evidence that establishes long-term,
at-will breastfeeding as a risk factor in BBTD. Limitation of the
duration
of breastfeeding has documented negative consequences to the baby and
mother. "Baby Bottle Tooth Decay" is a disease of artificial feeding.
