My teeth are somewhat sensitive. I use the Sensodyne Pronamel toothpaste. While my teeth are not super yellow, they do get stained easily because I drink tea. Rarely coffee and I don’t smoke. The teeth staining issue was something I’ve always remember having even before I drank tea. It is a familial trait dentists have told me so I can’t really prevent it. Funnily enough, i had less staining when I lived in London and other hard water areas, but I have grown and lived mostly in soft water areas.
In this box, there are 28 pouches, each with two strips, one upper, one lower. You wear them for
5 minutes a day. I put mine on before brushing my teeth at night. I think I forgot to put them for about 6 times in the whole thing, mostly toward the end and I would only skip one day.
Price: $29.99 CAD before tax, two day sale at SDM, usually around $50 otherwise.
Conclusion: The box claims that the whitening is subtle. Yes, so subtle that I’m not sure if it did anything. My teeth stain easily so this was probably not strong enough, and the whole process was easy though the strips did like to slide around on my teeth at times. I’m willing to try the other ones such as the Stain Guard ones and even those which are required to be on for 30 minutes. I don’t really recommend this product unless you have super sensitive teeth and relatively ok teeth since they do not whiten that well.
