A child is at the critical age to discontinue a habit for preventing dento-maxillary changes. Which age is emphasized?

• A. 2 Years
• B. 3 Years
• C. 4 Years
• D. 7 Years

Answer: (B)

A rapid period of dento-alveolar adaptation occurs in early childhood, so stopping non-nutritive habits during this window helps prevent lasting tooth and jaw changes. Around three years of age is the peak moment when the dento-maxillary structures are still malleable and before permanent teeth erupt in a way that makes changes more difficult to reverse. If the habit continues past this age, there’s a higher risk of anterior upper incisor proclination, increased overjet, and potential open bite or crossbite, which are harder to correct later. Stopping by about three years gives the best chance for the teeth to develop normally without the need for interceptive orthodontic treatment. Earlier cessation is beneficial, while continuing beyond this age makes spontaneous correction less likely.
