It is generally advised not to drink water while whitening strips are on the teeth because water can wash away or dilute the bleaching agents before they fully work, reducing the effectiveness of the whitening treatment. However, drinking water immediately after removing the strips is usually safe and even encouraged to rinse away any residue and refresh the mouth. Waiting 30 minutes after treatment before consuming other beverages or foods, especially if the teeth are sensitive, is also recommended to allow enamel pores to close and reduce staining risk.

Key Points:

• Drinking water during the whitening treatment is discouraged to allow the peroxide gel to work effectively.
• Hydrate before applying the strips to avoid thirst during treatment.
• After removing the strips, drinking water immediately is safe and can help rinse the mouth.
• Avoid colored, acidic, or staining drinks for at least 30 minutes after treatment.
• Use strong adhesive strips with caution; some types may adhere better and be less affected by water.
• Watering down the whitening gel during treatment impairs the whitening process.

In summary, do not drink water while the whitening strips are on , but it is fine and even recommended to drink water after taking them off.
