A tooth whitening gel composition is provided to be able to increase resistance against saliva, adhesion to the surface of teeth and contact time with whitening ingredients by immediately forming a non water soluble-film on the teeth after being applied thereto. The tooth whitening gel composition comprises at least one non water-soluble film forming agent selected from the group consisting of ethylcellulose, ethylene/acrylic acid copolymer, ethylene/acrylic acid/vinyl acetate(VA) copolymer and ethylene/propylene copolymer. The composition comprises 5-50 wt.% of the water-insoluble film forming agent, 0.5-20 wt.% of a whitening ingredient, 10-40 wt.% of an adhesive, 0.1-5 wt.% of a neutralizing agent, 0.01-3 wt.% of an emulsifier, 0.01-3 wt.% of a stabilizer and the remaining amount of a solvent.
