Do Crest Whitestrips Really Work? I Put Them to the Test

By sonyaleebenham |


Recently, my darling 5-year-old son made a comment about my “yellow teeth.” Hmm… I have no idea how that happened, given that coffee and red wine are my two favorite things to consume. Anyhow, it was just the kind of honesty I needed to motivate me to investigate an at-home whitening treatment.

The last time I tried Crest Whitestrips was shortly before I got married. That was 9 years ago. As it turns out, a lot has changed. Crest now offers a variety of whitestrips available in different strengths and treatment lengths. I opted for maximum whitening with Crest 3D White Intensive Professional Effects Whitestrips.

With Intensive Professional Effects, the strips should be worn for 2 hours a day, for 7 days. The results, according to the Crest 3D site, are on par with a $500 treatment in a dentist’s office and the strips contain the same enamel-safe whitening agent.

I was really impressed with how well the product adhered to my teeth, thanks to Crest’s AdvancedSEAL technology. They stayed in place the entire two hours. I’m not going to lie, I found the time to be pretty restrictive – two hours is a long time! But I did see results after the first application.


Unfortunately, my teeth are sensitive. Really sensitive, in fact, and whitening treatments can increase sensitivity. I have a pretty high threshold for discomfort and the sensitivity is temporary so I thought I could handle it. In the end, the new high-powered strips were too much for me. I quit after 4 applications.

The good news is that I think 4 applications was plenty! My teeth look fantastic and I’m very happy I stuck with it for 4 days. My husband even told me my teeth look like pearls! Next time, I will probably try Crest 3D White Gentle Routine Whitestrips designed for sensitive teeth. If sensitivity is not an issue for you, I highly recommend Professional Effects for whiter, brighter teeth in a short amount of time.

Crest 3D White Whitestrips Professional Effects is available at for $34.99.
