For bleaching, you need 30 ml of a 3% liquid( this is approximately two tablespoons of hydrogen peroxide).We rinse your mouth for about a minute. The solution in the mouth will foam a little - this is normal, since peroxide, reacting with a layer of contamination, forms bubbles.

After a minute, the teeth can be rinsed with water and cleaned.

The opinion of dentists

Dentists agree that whitening with hydrogen peroxide can be carried out independently, if all safety measures are observed.

Home whitening, of course, is very different from the procedures performed in clinics. Dentistry uses a 15 percent substance. On its basis, a mixture is prepared, which is combined with remineralizing gels containing glycerin. It protects teeth from possible destruction.


I make such a paste: half a teaspoon of soda per 20 drops of peroxide and 2 drops of lemon juice, the plaque removes perfectly, the teeth immediately noticeably whiter and, in principle, not very nasty to taste, like ordinary soda. .. and the gums do not bleed. Often, I think, it is impossible, but once a week, I think, there will be no harm. ..

I rinse my mouth for 3 weeks at night with 3% of hydrogen peroxide. The result is staggering. The plaque came off the teeth, there was no smell in the morning, and I still did not have such white and beautiful teeth. They are not snow-white, as in advertising. The color is smooth, natural, and I'm sure of my smile. I recommend to all.
