Crest’s teeth whitening strips have been reduced to just $30

Crest’s whitestrips are popular for good reason. And the range is available in an array of different variations, from strips for sensitive teeth (was $49.99, now $27.86, Amazon.com) to fast-tracked one-week whitening courses (was $44.99, now $29.99, Amazon.com) — there’s no denying the brand has your pearly whites covered. Perhaps the most popular offering from Crest is its professional effects course (was $45.99, now $29.99, Amazon.com), with 22 treatments to help reverse staining and dulling of the teeth without harming enamel. It’s as simple as peeling away the strips from their backing and applying them to your upper and lower rows of teeth, before leaving them in place for 45 minutes. The strips are even designed with a ‘no-slip grip’ to make the treatments easier to maintain. The kit is reduced by $16 in Amazon’s member sales event this week, which puts each session at just $1.36 a go. For context, professional in-clinic whitening can cost anything from $300 upwards and is usually priced higher.
