The dentist may suggest giving these children a form of medicine that can help them to relax and/or become sleepy.This is called "conscious sedation." Using conscious sedation may allow a child to become more relaxed. The infant's medication exposure can be limited by prescribing medications to the breast-feeding mother that are poorly absorbed orally, by avoiding breast-feeding during times of peak maternal serum drug concentration and by prescribing topical therapy when possible.

The transfer of medications into breast milk depends on a concentration gradient that allows passive diffusion of nonionized, non-protein-bound drugs.The mammary tissue in the breast is composed of clusters of milk-producing alveolar cells surrounding a central lumen.
Factors such as the dose received via breast milk, and the pharmacokinetics and effect of the drug in the infant need to be taken into consideration.
Your child should wear loose, comfortable clothing and may be asked to wear a gown.
You may be instructed to withhold food or drink beforehand, especially if sedation or anesthesia is to be used.
Notable exceptions are heparin and insulin which are too large to cross biological membranes.
The infant almost invariably receives no benefit from this form of exposure and is considered to be an 'innocent bystander'.
