We've been trying out Crest Whitening strips for few years now for tooth whitening. The product is a great deal and convenience at under $30, but has several challenges:
1.) You need to use it twice a day for 30 minutes to whiten your teeth for a week. It's comparable to other dental products for tooth whitening -- but the twice a day factor makes it a challenge.
2.) The strips only whiten your front teeth. It leaves no change to your back teeth and molars. It's a good value - but anyone looking closely can see a stark contract in the tooth color. The uneven whitening makes it a questionable deal - but is a good way to try out / experiment with tooth whitening without having to see (and pay) your dentist.
In summary - for around $30 - Crest Whitening Strips are a clever product to try out tooth whitening. The time commitment and uneven whitening can be drawbacks but its a good way to start out. What do you think? Have you tried these?
