Opalescence Go stood out to me because it comes ready to wear, so I did not have to mess with trays or complicated steps. I liked that it is designed for convenience while still being a trusted whitening option.
What I Looked for Before Buying
Before I chose Opalescence Go, I paid attention to a few important things:
