Not strong enough for me!, 17 Mar. 2013
Whilst my teeth did appear shinier and possibly marginally whiter if I take a very optimistic view...I think my staining and discolouration goes too deep into the tooth for this product to be effective! I think however it would possibly be more beneficial for someone with mild discolouration or just to brighten an already white smile.
At a reasonable price it's worth a try if the latter is you. I also have very sensitive teeth but did not experience any increase in sensitivity with this product .
