Crest 3D Whitestrips Professional Effects is comprised of thin, flexible strips that are coated with a tooth whitening gel containing peroxide. Designed to conform to the shape of your teeth, they work by keeping the whitening gel on your teeth, with no slipping or gel loss, to provide strong effective teeth whitening.
- No dental impressions required
- Strips are ready-made so you can use them right away
- At home or on the road, strips are portable enough to be used anywhere, at any time during the day
Whitening Strips have the whitening gel already added to them so they deliver a consistent, controlled dose each time. Strips do not have to be loaded before every use, unlike trays, which can cause oral irritation if too much gel is added.
- Pre-filled strips to control dosage
- Reduces gel from going over gums
For best results Crest 3D Whitestrips Professional Effects should be worn for 30 minutes once a day.
Step 1: Peel
For best results, do not brush your teeth immediately before applying the strips. Open the foil pouch and remove the slip. Peel the strip from its backing.
Step 2: Apply
Apply the gel side of the strip to your teeth and align the strips with your gum line, pressing gently for good contact. Fold the rest of the strip behind your teeth to keep it in place.
Step 3: Reveal
Wear your whitestrips for the recommended time, then carefully remove them and discard. Rinse your mouth and brush your teeth. Enjoy your new smile.

I was very skeptical about these, I'd been looking at reviews for a very long time and the sensitivity thing worried me.
I've tried other brands of tooth whitener and I have never seen instant results. I bought the 10 strips (5 pouches) that you wear for half an hour to have a trial run and after the first one my teeth were maybe about a shade lighter. I've just finished using all 5 pouches and my teeth are at least 3 shades whiter. I'm really happy with these! There's no build up of saliva in the mouth or bad taste when you wear them, they stick to the teeth very well.
I like to press them in between each tooth as well so they whiten more of the tooth. I wore one a day and left out one day to give my teeth a break because there is sensitivity which I think is inevitable but by the next day it's mostly gone, it isn't unbearable, barely noticeable. I also use Sensodyne toothpaste as well to help with the sensitivity. I would only use the half hour ones and whiten gradually though just to be safe. Overall they're the best whitener I've used and I can't wait to buy more!Reviewer: Em from Manchester
The delivery time was slower than expected to the point at which I thought I wasn't going to receive my whitestrips. This was a fault of Royal Mail however and Whitestrips4u gave me 10% off my next purchase which was nice. They have arrived now (after 5 days) looking forward to seeing some results.Reviewer: Candace Thomson from North Lanarkshire
I have heard and seen other companies make the same statements, but white strips really do work i love my teeth again!Reviewer: Gavin from Belfast
My friend Laura uses these strips and her teeth are so white. So I ordered the product to give it a try. Best money I have spent in a long time after using twice I began to see a huge difference. Recommend to all my friends. Ordered on a Monday night and product delivered by Wednesday morning. Great product.Reviewer: Margie from Northern Ireland
Was sooo excited when I order these as I watched videos on YouTube with people using these!
It took maybe about 3 days for these to arive and when they did I was excited. After 5 days i can see a difference so i will be ordering some more to carry on!Reviewer: Paris from Newcastle
I used the strips two times a day and five days in i saw a dramatic difference in my smile. Before going to the dentist, you should at least try these first. They might end up saving you a ton of money. The only downside is that the bottom strip isn't long enough but the product does deliver. TRY THEM!Reviewer: Stephanie from Shropshire
I had bought other teeth whitening products in the past with little results. In the end i bought these after a friend recommended them, and all i can say is WOW! I regret that I did not buy them a long time ago. They are simple to use and the results are magnificent - within a few days i really could see the difference and so could others. People have not stopped complimenting me on my teeth, and I really would advise anyone to buy these! They are the results that only dentists can give, for just a fraction of the price.Reviewer: Kate Lefton from Oxford
These really do work. Brilliant results!Reviewer: Carl Anthony from Lytham St. Annes
Simply amazing product! After 3 days teeth appeared noticeably WHITE! Would definitely recommend Crest Professional whitening strips to anyone.
