Clinically proven to whiten your smile 4-10 shades. GoSMILE The smile-beauty Company was co-founded in 2002 by Jonathan B. Levine, DMD, and his wife, Stacey, in response to his celebrity patients who wanted to whiten their teeth simply, effectively and safely. GoSMILE began with an ampoule - a single dose, brush-on application of whitener - that revolutionized the concept of on-the-go teeth whitening. GoSMILE is committed to products that not only make you look good but are also good for you.
