These sort of work….. but are a lot of work for me to use. morning and night. There just is NOT enough bang for my buck and also the whitening power misses BETWEEN my teeth so I feel gel in a tray is the next option or a one time whitening session from my dentist which includes trays and gel for later touching up!
