An oral composition with a sol-gel phase transition formulation comprises 5-50 wt.% of a thermo-sensitive polymer, wherein the sol-gel phase transition temperature is 31-32 deg.C. The composition further comprises 0.001-10 wt.% of at least one foul breath removing ingredient selected from the group consisting of a pine needle extract, cetylpyridinium chloride, a green tea extract and a Salix koreensis extract.
