Objective This study aimed to investigate the relationship between patient satisfaction of outcomes and tooth color changes during and after tooth bleaching. Methods In this clinical trial, 63 volunteers participated in an in‐office bleaching procedure using a 40% hydrogen peroxide gel. The treatment consisted of two sessions, each comprising two 30‐min applications of the bleaching gel. The L*, a*, and b* values of six maxillary anterior teeth were measured at baseline (T1), after the first bleaching session (T2), after the second bleaching session (T3), 1 week after the second in‐office bleaching session (T4), and 3 weeks after the second in‐office bleaching session (T5). The color differences (ΔE00) were calculated using CIEDE2000. A satisfaction scale with a score ranging from 0 to 3 was used to record participants' level of satisfaction with their tooth color at each time point. The data were statistically analyzed using repeated measures analysis of variance and logistic regression (α = 0.05). Results Significant correlations were observed between ΔL*, Δb*, and ΔE00 values at T3 and patient satisfaction (all p
