Listerine Dissolving Whitening Strips: Convenient or Wasted Cash?

Listerine's quick dissolving strips are heralded as a more convenient way to whiten your teeth.  There's no dentist visit needed, and the strips dissolve.  For the Crest strips that we've used many times - you need to take the slimy, messy plastic strips off your teeth.  Listerine has eliminated that step.  But do they work?  

It takes around 5-10 minutes for them to dissolve - so if you are "hiding" your whitening from co-workers, keep in mind this gap.  Listerine expects results in around two weeks, but does not state the strength of the chemicals on the strip, which are a key factor to how much whitening you will experience.  

We'd recommend these if you are considering a non-dentist option.  They're convenient and save a mess.  If you've tried them - let us know how they worked versus the Crest Whitening Strips that have become the market leader in this space.  Here's what they look like on the store shelf with an average price around $25 to $30 for a two week supply:

The teeth whitening that whitened my teeth best was Achromasia 22%. I have tried the Opalescences and Nite White teeth whitener. They didn't work that well.

I used Listerine for a while.. but just couldn't stand the taste. Previously found that colgate white strips worked pretty well although they are kind of expensive.
Last month I found a free trial offer to teeth whitening tips which are free! I started using them last week.. and they work better than the colgate strips!

I'll try and find the site I got them off.. hope this helps anyone searching for real teeth whitening products! Postage was $6.95 and it only took 4 days to come through in the post. I have been using the tips for 2 weeks now, and my teeth have become 4 shades lighter!

Strips do work, but the problem is that it takes alot of applications. The reason is that the percentage of hydrogen peroxide in listerine is approx 4%, that equates to 12% carbamide peroxide, weak at best.
I suggest using a kit where
the gel is about three times as strong and is safe to use
when used as directed.
It worked for me.
