Overall winner: Opalescence 45% Teeth Whitening Gel Syringes (4-pack) Refill Kit

Key Differences

Choose MySmile (A) if you want a more affordable, quick-results gel sold as six pens with 10-minute whitening claims and easy-use syringes. Choose Opalescence (B) if you prefer a higher-strength, professionally oriented carbamide-peroxide formula sold as four syringes (packaged as two 2-syringe packs) and are OK with stronger effects that some users report can irritate gums
