Crest Whitestrips - 5 minute per day ones .

[HarryB]

I just got these from Amazon and wondered if anyone here has used them and could asnwer a couple of questions for me please.

• How many days before you see the results?
• As an ex-smoker, one of my front teeth is darker than the other, so should I cut a strip down to size and use that on my worst tooth first then carry on as per instructions?

Many thanks

I meant answer, sorry baby waking up.

reminds me, i've got a box of those to use up.. got bored with doing it before I'd even finished the week's worth
and my teeth get sensitive to it

Yes yes I use them and likemissmelly have lots to use up. I reckon after about 10 days I saw a difference.. I don't know about cutting them down to size, I'm not sure if it would stay in place. You could try..
