In the documented progression order, which tooth group is affected first?

• A. Upper incisors (maxillary anterior teeth)
• B. First molars (mandibular primary molars)
• C. Second molars (maxillary primary molars)
• D. Canines

Answer: (A)

Early childhood caries often shows a characteristic progression pattern, with the maxillary anterior teeth taking the lead. The facial surfaces of the upper incisors are most exposed to cariogenic liquids that a young child might hold in a bottle—formula, juice, or milk—especially when the child sleeps with the bottle. These liquids pool around the maxillary incisors, and the lip and cheek guard less of the surfaces, while the tongue offers limited cleansing in that area. That combination makes the upper incisors the first sites to demineralize and develop caries. From there, the disease can spread to adjacent teeth, with the canines and posterior teeth becoming involved as exposure and plaque accumulation continue. The mandibular molars and other posterior teeth are typically affected later, partly because they are less exposed to pooling liquids and are more protected by the tongue and saliva flow during sleep. So, the earliest and most consistently affected group in the documented progression order is the upper incisors.
