I tried out Optic White Dual Action toothpaste, alcohol-free mouthwash, and the 360° Optic White toothbrush. The toothpaste and mouthwash are both pleasant-tasting and the toothbrush is flexible and comfortable. And I have to say, you can really feel the products working on your teeth! I’ve been a little leery of some whitening products in the past, because prolonged usage can damage tooth enamel, but these are enamel-safe, and can be used beyond the 4-week “test period.”
