I saw a wonderful difference in my teeth after a week! so I stopped and now I am just saving them for when it gets closer to holidays for the perfect smile!(:

I thing that the Professional effects whitestrips are one of the best products out there. All the Whitestrips are somewhat sensitive to your teeth, but after a while you get used to it. Start out by using them only once a day---or every other day.

I would recommend this brand to anyone. You can notice the difference in tooth coloring with few uses and its easy and simple. Now I can say I am not afraid to smile

Strips are easy to apply. Seems to take several weeks to notice any improvement. Stubborn stains on cracked teeth are still visible but fading. The strips cause gum irritation and inflammation.

This product delivers on its promise. When used as directed, it whitens your teeth without causing sensitivity. Results are noticed quickly. I like to use twice a year but sometimes the whiteness lasts longer!

Love the product - but on my last two usages (same box) for the upper teeth - the peel off did not peel off. The whole sheet came out perfectly and I cannot get the top to peel off. Please tell me what to do. Thanks

I am a coffee and tea drinker and after several years, this has ruined the whiteness of my teeth. I think the effects of this product was well worth the price.

[This review was collected as part of a promotion.] I'm so excited about this journey..I've been wanting to try these for awhile but have been a bit pricey so when I saw these I jumped on the opportunity

Stunning! I bought 2 boxes and my teeth are so much whiter! The strips took off years of staining from coffee and tea and all other staining foods! So amazing, and I reccomend to all my family and friends and may even buy my sister a box!
