Aim: This study evaluated the chromatic and surface changes on enamel after toothbrushing with whitening and desensitizing toothpaste. Materials and Methods: Sixty enamel blocks were prepared, pigmented, and stratified according to initial Knoop microhardness and divided into six groups. The average roughness (Ra) was determined from two readings. After 24 h in artificial saliva, 10,000 cycles of simulated brushing were applied. The Ra was measured after 5000 and 10,000 cycles, and tooth wear was determined. The mean roughness was evaluated, and tooth color was recorded before and after treatment. Results: Brushing with dentifrices increased the roughness of enamel in all groups. It was lower for Colgate Sensitive Pro-Relief + Bleaching, Colgate maximum protection anti-caries, and the control group. Greater roughness was observed in dentifrices containing silica. Greater wear was found with Sensodyne bleaching extra fresh and in the control group. The best bleaching effect was found with Colgate Sensitive Pro-Relief + Bleaching. Colgate Sensitive Whitening, Oral-B Pro-Health Whitening, and Sensodyne Whitening Extra Fresh showed major changes on surface roughness. Conclusion: The physical characteristics of the minerals of the toothpaste appear to be the major determinant of dental abrasion, not their quantity or whitening capacity, or rather their ability to remove enamel surface stains.
