Avoiding acidic foods and drinks is important after teeth whitening treatments, as they can weaken enamel and increase the risk of re-staining. Acidic items such as citrus fruits, vinegar, and carbonated beverages can make the teeth more susceptible to staining by softening the enamel. At SOS Wax and Skincare, clients should be advised to limit their consumption of acidic foods and drinks, especially in the days immediately following a whitening treatment, to protect their enamel and maintain their results. Recommending alternatives, such as drinking water or milk, can help clients make better choices for their oral health. This tip is particularly important for clients who have invested in professional whitening services and want to protect their results for as long as possible. Providing this guidance ensures that clients understand the impact of their diet on their whitening results and supports long-term oral health.
