Approximately how many adults avoid smiling and feel embarrassed about their mouth and teeth?

• A. 1 in 4
• B. 3 in 10
• C. 1 in 2
• D. 7 in 10

Answer: (B)

This question is about how common a psychosocial impact of dental health is in the adult population, based on survey data. Surveys on how people feel about their mouth and teeth show that a noticeable but not majority portion avoid smiling or feel embarrassed. The best estimate among the options is about 30%, meaning roughly three in ten adults. This aligns with typical public health findings that a substantial minority experience embarrassment about their teeth, influencing social interactions and dental care decisions. The other figures aren’t as consistent with what surveys usually reveal: a quarter is plausible but lower, half would imply a much larger burden, and seventy percent would be unusually high for the general population.
