I have, naturally, decent white teeth even though I drink several cups of coffee a day.
But still there was a little difference with the foam teeth whitening "Dual Foam”From BeconfiDent!
”With BeconfiDent's Dual Foam Whitening, you get your dream smile naturally. No braces are required and you do the treatment in just 5 minutes a day. You do the treatment morning and evening for 3 weeks and the result corresponds to a treatment performed by a dentist. Dual Foam is now also sold at selected pharmacies.”
There are two different foams that you brush your teeth with instead of toothpaste.
"Foam 1" cleans. Brush for 1 minute.
"Foam 2" bleaches. Brush for 2 minutes.
In other words a little longer than when you usually brush your teeth for 2 minutes. The first foam tastes good of mint, the second a little more artificial but still perfectly okay. Thought it tasted like apple, but do not think that was the point;)
Geez so hard it was to take pictures of the teeth and get exactly the same light in two pictures, despite different occasions. But I succeeded in the end!
Before.
Answer yes, the dentist thought I should have braces in elementary school. But I refused;)
My high canines are just charming!
After.
Before after.
Do not think that anyone else would see the difference in reality, because I did not have yellow teeth before. But I think this would work if you have a bit yellower teeth.
The afterimage is taken after 3 weeks, but I saw about the same difference after 4 days (photographed then as well, and those pictures show no major difference from the end result)
Anyone else tested this?
