Post-whitening sensitivity is a common side effect experienced by some clients after teeth whitening treatments. This sensitivity occurs when the whitening agents temporarily open the pores in the enamel, exposing the dentin underneath and causing discomfort when consuming hot or cold foods and drinks. At SOS Wax and Skincare, clients should be advised that any sensitivity experienced post-treatment is typically temporary and should subside within a few days. Using toothpaste specifically formulated for sensitive teeth, avoiding extremely hot or cold foods, and following any additional aftercare instructions provided by the technician can help alleviate discomfort. Educating clients about potential sensitivity helps them feel more prepared and ensures they take the necessary steps to minimize it, leading to a more comfortable and positive whitening experience. This guidance is particularly important for clients with a history of tooth sensitivity, as it helps them manage this side effect effectively.
