An oral composition includes high stain removal efficiency relative to its abrasive ability. The oral composition contains fused silica and a dental abrasive. The oral composition has a high stain removal ability relative to the abrasive ability thereof. In other words, the ratio (stain removal ability/abrasive ability) of the oral composition is high. Accordingly, the use of the oral composition makes it possible to efficiently remove stains without damaging the teeth more than necessary.本發明之課題在於提供一種相對於研磨力而言色斑(stain)去除效率甚高之口腔用組成物。藉由本發明，可提供一種含有熔融二氧化矽及牙齒研磨劑之口腔用組成物。該口腔用組成物相對於研磨力之色斑去除力甚高。意即，該口腔用組成物顯示出甚大之(色斑去除力/研磨力)之值。因此，使用該口腔用組成物不會對牙齒造成必要程度以上之損傷，而可有效進行色斑之去除。
