Use of chemical bleaching has side effects, so it is important to find an alternative natural dental bleaching agent. <em>Averrhoa bilimbi </em>contains peroxide and oxalate acid that possess tooth whitening properties. <strong>Objective: </strong>To determine the change in color of dental enamel after the application of <em>Averrhoa bilimbi </em>and 10% carbamide peroxide. <strong>Methods: </strong>Samples were 20 post-extracted of the two tested materials premolars (10 specimens each for <em>Averrhoa bilimbi </em>and carbamide peroxide application). After the application, the specimens were incubated at 37ºC for 2 hours, washed and soaked in aquadest before further incubated for another 14 days. The colour changed was observed by 5 independent observers using shade guide. <strong>Results: </strong>Quantitative and qualitative analyzes were performed. Qualitatively, A3 color has changed into C1, A2, D2, B2 and B1 in the <em>Averrhoa bilimbi </em>group. A more significant color change in the 10% carbamide peroxide group (<em>p</em>=0.005) compared to <em>Averrhoa bilimbi </em>group (<em>p</em>=0.005) were observed. The difference of resulted enamel colour change was statistically significant (<em>p</em>=0.002). <strong>Conclusion: </strong><em>Averrhoa bilimbi </em>had a good prospect as dental bleaching agent since its application effectively resulted in a slight enamel colour change although its whitening properties was still lower than 10% carbamide peroxide.</span> <p class="MsoNormal" style="text-align: justify;"><span style="font-size: 10.0pt; color: black;">DOI: 10.14693/jdi.v19i3.134</span>
