How long should a patient generally wait before brushing their teeth after consuming acidic foods or drinks, per current ADA (MouthHealthy) guidance?
Show answer and explanation
Correct answer: D. About 60 minutes (the ADA's MouthHealthy guidance specifically recommends waiting about an hour to allow saliva to neutralize acids and re-harden softened enamel)
The ADA's own MouthHealthy patient education resource specifically advises waiting about an hour after eating acidic foods before brushing, giving saliva time to naturally neutralize the acids and allow the temporarily softened enamel to re-harden before it's exposed to a toothbrush. (Other general dental sources commonly cite a broader 30–60 minute range, but the ADA's specific current published figure is 60 minutes.)
