A pH balancing rinse helps to neutralize acidity in the mouth after consuming acidic foods or drinks. This can protect teeth from erosion and maintain the results of whitening treatments. Clients should be advised to use such a rinse after meals to help protect enamel and prolong whitening results. This is especially important after consuming acidic beverages like soda or citrus juices. Providing this tip helps clients maintain a balanced oral environment, supporting both their whitening and overall dental health.
