Didn't Work for me.
If you think this equals to a laser whitening you will be disappointed 😞. I have been using it for about a month and i haven't seen a difference. I'm a coffee drinker and have never had a professional whitening, so i was hoping this natural way would do the job but it didn't. Maybe works as a &#34;maintenance&#34; after a professional whitening. Bummed!
