Crest Whitening Emulsions 1 Minute Apply & Go Whitening Treatment is the next breakthrough in teeth whitening.

The unique formula is enamel-safe, starts working instantly, and stays on your teeth 10 times longer, with no need to rinse, brush or remove. This convenient size allows you to apply Crest Whitening Emulsions with precision and includes a stand for wand applicator and tube storage.
