Poor maternal oral health during pregnancy can increase the likelihood of which condition in the child after birth?

• A. Early childhood caries
• B. Tooth enamel fluorosis
• C. Delayed tooth eruption in adolescence
• D. Increased adult tooth wear

Answer: (A)

Maternal oral health influences the child’s future caries risk through the transmission of cariogenic bacteria, especially Streptococcus mutans, from mother to baby. When a mother has a higher bacterial load due to poor oral hygiene or disease, close contact and normal caregiving behaviors can pass these microbes to the infant. Once the child’s teeth erupt, these bacteria metabolize sugars from the diet and produce acids that demineralize enamel, leading to early childhood caries. So the condition most likely to develop after birth is early childhood caries. The other options don’t fit this transmission-based mechanism: enamel fluorosis results from excessive fluoride during enamel formation, delayed eruption has different etiologies, and increased adult tooth wear stems from factors encountered later in life rather than maternal oral health during pregnancy.
