Can I eat or drink immediately after a treatment?

After each whitening treatment, your teeth are temporarily more prone to staining. To protect your results, avoid coffee, tea, wine, dark sauces, and other strongly pigmented foods and drinks for at least 1–2 hours.

During this time, drinking water is perfectly safe and will not affect your results. Staying hydrated with water may even help rinse away surface residues and protect your whitening effect.
