I have tested BeconfiDent's toothpaste whitening previously, which yielded results.
The difficult thing, though, is that show the result, I think it's very difficult to photograph teeth. The before and after pictures look almost the same, although the difference is quite large in reality!
Anyway, now I have tested another teeth whitening, also from beconfiDdent, but this time with munskena.
And it was even better! You should do this 15 minutes a day, for 10 days. But I noticed a huge difference right away!
I missed putting extra gel where I have my "high fangs". This resulted in these canines not being bleached in the same way.
A miss by me, though blessing in disguise as I have, I can now show the difference much easier! :)
I did not have particularly yellow teeth before (despite coffee addiction), but in comparison, the canines are super yellow!
