Opalescence PF Refill Syringes $45 (includes 4 syringes)

Although the start-up cost for professional custom-made whitening trays is high r than over-the-counter whitening options, in the long run, this option actually will save you money on continued whitening (while whitening at a professional standard) since the gel refills are actually more economical than the cost of over-the-counter whitening products of lesser efficacy.
