Background : Enamel of the teeth were vulnerable to discoloration and would affect the aesthetics of the teeth. The treatment for extrinsic discoloration could use bleaching treatments, however bleaching has side effects that could cause erosion of the teeth and would also affect the roughness of the enamel surface, alternative bleaching agents were expected to minimize the side effects of bleaching agents in general. The purpose of this study was to know the differences in surface roughness after bleaching with siwak extract, lime, and guava using home bleaching technique. Method : This study was a laboratory experimental study with samples of premolar teeth, 24 teeth were then divided into four groups: 100% siwak extract, 100% lime extract, 100% guava extract, and a control group with pH 6.8 saliva. The results of the research data were analyzed by the One-Way Anova. Results : Analysis of research data on tooth surfaces after being collected with One-Way Anova obtained a result 0.752 (P> 0.05) which means there was no significant differences among groups. Conclusion : The three extracts also contain calcium and phosphate which could protect the teeth from acid, so the surface roughness of the tooth could be prevented
