As of 2015, the teeth whitening system that has the best review on ConsumerSearch is Ultradent Opalescence PF Teeth Whitening Gel. Other teeth whitening systems that received good reviews are Crest 3D White Whitestrips Advanced Vivid and Supersmile Professional Whitening System.
ConsumerSearch states that Ultradent Opalescence PF Teeth Whitening Gel is among the very best products for teeth whitening available for home use. Although considered to be highly effective and easy to use, it may cause gum irritation. Because it is a professional-grade gel, the mouth trays and the gel itself must be administered by a dentist. The product uses a timed and sustained release formulation that takes effect over a period of eight to 10 hours and whitens teeth overnight, explains ConsumerSearch.
