How long should one wait after consuming lemon juice before brushing teeth to protect enamel?

Answer

At least 30 minutes

When consuming acidic beverages like lemon water, the citric acid temporarily softens the tooth enamel, making it vulnerable to mechanical abrasion. Brushing the teeth immediately following acid exposure risks scrubbing away this softened enamel layer, leading to permanent wear. To counteract this, a specific window of time is recommended for waiting before initiating mechanical cleaning. One should wait a minimum duration of 30 minutes after finishing the acidic drink. This waiting period allows the mouth's natural saliva production to buffer the acid and begin the remineralization process, restoring the enamel's hardness sufficiently to withstand gentle brushing without incurring further damage.
