How long should a patient WAIT before brushing their teeth after consuming acidic foods or beverages?

Patients should wait at least 45–60 minutes before brushing after consuming acidic foods or beverages. The acid temporarily softens the enamel surface (through demineralization). Brushing immediately after acid exposure abrades the softened enamel and accelerates tooth wear. Waiting allows saliva to buffer the acid and remineralize the enamel surface before mechanical brushing force is applied. This is especially relevant for patients with bulimia, GERD, or high citrus intake.
