The correct type of swallowing is formed by which age?

• A. 1 year
• B. 7 years
• C. 2-3 years
• D. 6 months

Answer: (C)

The key idea is how swallowing patterns develop with age. Children start with an infantile or suckling type of swallow, which relies more on a forward tongue movement and less on a firm lip seal. As neuromuscular control matures, the pattern becomes more adult-like: the tongue elevates to the palate, the lips seal, and swallowing becomes coordinated with a stable jaw position. This mature or functional swallow typically forms around two to three years of age. By this time, most children can swallow with the tongue pressing against the palate and the lips closed, reducing anterior tongue thrusts that can affect dental alignment. If the mature swallow isn’t established by this window, there’s an increased risk of persistence of tongue thrust habits and related occlusal issues, which may later require intervention.
