Infants typically begin tooth eruption in which age range?

• A. 3 to 5 months
• B. 6 to 8 months
• C. 6 to 10 months
• D. 12 to 14 months

Answer: (C)

Tooth eruption in infants typically marks the start of primary dentition, with a common window around six to ten months. The first teeth to emerge are usually the lower central incisors, followed by the upper central incisors. This timing reflects the normal sequence of dental development and is influenced by genetics and overall health. While some babies may begin as early as about four months or as late as twelve months, the six-to-ten-month range represents the typical onset that clinicians and educators use when teaching infant development. Parents may notice increased drooling, gum swelling, and a tendency to chew on objects as teeth begin to break through the gums.
