Sodium bicarbonate, hydrogen peroxide and urea peroxide contained in whitening toothpastes, although they have a whitening effect, lead to increased tooth sensitivity. Therefore, experts do not recommend using them all the time. Experts also say that all whitening pastes make only the surface of the tooth lighter, but not the tooth itself. In addition to whitening, manufacturers of toothpastes promise us complete protection against caries. Experts from the University of Saar (Germany) set out to test modern toothpastes. As a result of the experiment, scientists have come to the conclusion that no toothpaste can protect teeth from caries. Pastes do create a certain protective layer around the teeth, but it is too thin to prevent the destruction of enamel. There is still no consensus on the advisability of including various active substances in toothpastes, for example, vitamins, enzymes, extracts of various herbs, antibiotics. The only undoubtedly effective component is fluorine.

I ordered bleaching discs from America, which specialist Peter Snyakin spoke about above. My dentist recommended them to me.
This is an expensive pleasure, but still worth the purchase. I took a course of 2 weeks (I took the strongest concentration for strong enamel) and saw a significant wow result after 3 days of use.
Wore whitening strips for 1 hour every day. The effect lasts a long time, only requires constant maintenance (do not drink coffee, cola and wine). In addition, I used whitening toothpaste of the same company as the strips.
The tone of tooth enamel is given by nature, as well as its quality + there is a dependence on the composition of saliva, on the food and drinks that we use. If you need a white-toothed smile, but it is not there initially, you will have to regularly and periodically seek professional help from a dentist, since your own natural shade still "wins", and one-time dental manipulations will not permanently solve the problem.
From personal experience I can say that I noticed the difference: if, after drinking coffee / tea or something other "coloring", you brush your teeth with a whitening paste, the effect will be better than if you brush with a regular one. Since I smoke and really love coffee, I always have 2-3 tubes of different pastes, one of them is whitening, which I use without fanaticism, and 3-4 times a week, with two cleanings a day, every single dentist says, that they do not notice the consequences of smoking and drinking coffee :)
This is not a myth, but the effect is insignificant, rather supportive. I have not seen such a person whiten their teeth from scratch with the help of one paste. The problem with whitening pastes in exposure is that they are not in contact with the teeth long enough for whitening to occur.
If you really want to whiten your teeth, there is home whitening. A special gel is taken, which is placed in a mouthguard and put on the teeth. A person can spend either a night with a mouth guard, or some time during the day (in the morning 30 minutes and in the evening 30 minutes) - depending on the concentration. The home whitening course lasts two weeks - and it really works. True, mouthguards are not sold in the pharmacy and you still need to go to the dentist to make it (you can also buy the solution there). Taking into account the cost of the mouthguard - you can't save much on home bleaching - it will cost about the same as whitening in the dentist's office.
Does home bleaching in this case have any advantages over whitening at the dentist? Whitening is painful for some people at the dentist's office, but it is possible to dose at home. And then there is some particularly problematic tooth, yellower than the rest - and at home it can be modified gradually.
There are also whitening plates. You stick them on your teeth, walk around, and they have an effect. These are sold in America, but I have not seen them in our pharmacies.
It depends on what effect you want to achieve. Minus one tone is reality. My experience: Pearl drops minus one tone for two months of daily use.
Tooth whitening pastes are not a myth. By R.O.C.S. the whitening effect was not noticed, Brilliant is really good with the whitening complex of the same name, Rembrandt Sensitive is very effective, I did not have to spare the money spent, the dentist recommended.
The dentist "threw me" on whitening Zoom. Here it is really effective. But only later did I learn how painful and harmful it is. Not worth the pain. Even if they pay me a million, I will never repeat it. Pastes do not help at all, but there are homemade whitening kits - they are praised by many!
Reality. However, as already mentioned, the effect "WOW YOUR TEETH WERE BROWN AND BECAME WHITE SNOW!" will not - the teeth will only become slightly lighter. To achieve at least such an effect, you need to brush your teeth every day, twice a day and at least three minutes (which many do not know about), because the effect of any therapeutic paste depends on the exposure time of this very paste on the surface of the teeth.
But even the implementation of all these recommendations will not always have the desired effect - you may have plaque that can be removed only during professional cleaning at dentist.
So it is always better to consult with a specialist, and you will delight others with a beautiful smile =)
Just last week I went to the periodontist who forbade me to use whitening paste. He explains this by the fact that whitening pastes contain many whitening substances that harm the enamel of the teeth.
But this is not the most important thing. The most important thing is that a person cannot evenly apply the paste with a brush to his teeth, as well as brush. Why the enamel of the teeth becomes "multicolored".
But I do not exclude that this case applies directly only to my type of teeth
In fact, toothpaste can only whiten one tone maximum, since the paste is quite delicate and does not spoil the enamel at all. If you want to whiten your teeth so that you have a snow-white smile, then it is best to contact your dentist. There will be much more effect than toothpaste.
I observe oral hygiene perfectly: I brush my teeth in the morning, day and night. Only they are yellow like the sun anyway.
