Woo Hoo for White Teeth – Crest Whitening Strips (Before & Afters)

I have finally completed my 20 day treatment of Crest 3D White Strips. I have tried the Vivid strips before and found the results a little disappointing so I was delighted to have the opportunity to try the Professional Effects.

There are 20 days worth of treatments in the box, with an upper and lower teeth strip in each packet.

On first opening a packet, I found that the strip had come away from the plastic backing and was stuck to the side of the wrapper. It was a little tricky to remove…maybe the postman left the package out in the sun before delivery. This didn’t happen with any of the other packs. I also found it a little tricky to apply the strip to my bottom teeth without it curling. After a little frustration I managed to find a technique that worked for me after a few days.

Compared to the Vivid strips, these stay on much better. They don’t move or slide around. I even found that I could still talk whilst wearing them (with a little slurring).

Here are the results:

Day 1

Day 20


I hated posting these images – I need Invisalign stat! Ah well, at least my teeth are brighter.

I was delighted with the results. They started to work immediately – my family commented on my teeth after only one treatment although most people need to wait a few days to see results. I assume this is down to my tea addiction!

The gel itself tastes like toothpaste although I’m not fond of the mouth full of whitening gel after I remove the strips. Regardless, it’s completely worth it.

I was going to fork out a few hundred for Zoom whitening but read quite a few reviews where people complained about sensitivity. I had no sensitivity with these strips. That being said, I have never had sensitivity with any teeth whitening treatments in the past. If you suffer from that problem, then you possible feel some sensitivity. I used Sensodyne toothpaste, which has a high level of flouride, to keep sensitivity at bay.

I highly recommend these strips!

They were quite hard to find in Ireland in the past but they’re available from Frownies for €48.90.

    Can you tell me which side you apply closest to tooth? The grainy or smooth side?

    I read that Crest whitening strips contain hydrogen peroxide which can make your gum sensitive. I was looking around for a hydrogen peroxide free product and found Stella white strips, have you tried them?

    Ooh – how do you use these? are they just like self adehise & stick to your teeth? they dont slide off or anything? how long do you have to keep them on for?

  • Billie

    Wow looks good! looks like u had super white teeth before though lol – & u dont need invasalign at all – ur really pretty!!

    trust me, more hassle than it’s worth.

    my bro’s girlfriend tried a teeth whitening kit where u put gel inside an invisalign type mould & sat with them in for at least an hour… so u cant speak! & it rlly made no visible difference at all!
