Reviews
To avoid being told, but I know from my own experience that the whitening strips of enamel do not spoil .After using them for only a few hours, sensitivity appears.But if you follow the procedure at the right time, you will not be bothered.Five years ago I tried to whiten my teeth with a drug from another manufacturer.It was expensive, but after the third time it was used, it hurt me to talk.As a result, I threw those strips.
I was recommended by Crest 3d White, and I decided to buy them.For the first time I ordered only five packages, so that it would not be a shame to throw it away, if that.They cost me only 300 rubles.After the procedure, I realized that in a half-day the sensitivity of appears.Within 8 hours the teeth just ache.And I decided to whiten my teeth only on weekends.In a week I used no more than two packages.The result is noticeable.I was even asked if I bleached my teeth.And I used only 5 packs, having passed a course in 20 pieces.
I ordered more strips to whiten the teeth before important events.The result has been holding for two years.The enamel starts to get dark, but it's only visible to me.In my response I want to warn.Do not order bleaching products on Russian sites.There's a very big cheat!
Every girl wants to have a snow-white smile, and I'm no exception.I went to my dentist who offered me various chemical and laser whitening procedures for .I refused them.They just kill the enamel, and they are also very expensive.Then the doctor advised me to try the Crest 3d White tooth whitening strips.
After reading the reviews, I decided to buy them.Their composition is still a mystery to me.On the package it is not specified.After rinsing my mouth, I pasted a long plate on my upper teeth, and on the bottom - a short one.Do this carefully, because the adhesive properties of the plates leave much to be desired.The edges of the strips wrapped around their teeth and evenly distributed the gel.As a result, with the installation of plates was carried for at least 5 minutes.According to the instruction, the procedure should last two hours.At this time you can not drink and eat.
The teeth of the have become whiter, but only a little .An unpleasant surprise was that, it turns out, the fillings are not bleached.And it's on my front tooth.But since the enamel bleached very slightly, the difference in color is almost imperceptible.I want to warn that if the gel gets on the gums, there may be irritation.In general, the result is good.
I've heard about these strips for a long time, and now I decided to try them.For the first time I bought a set of 14 pieces, and I'm glad that I did not take more.Just want to say that Crest 3d White is coping with its task.Zubki these plates and really bleach.How they act, I did not understand.Some sticky little plates with adhesive tape and menthol smell will defeat the plaque on the teeth.
According to the instructions, for 15 minutes there is a light whitening of , for 30 minutes - classical, and for an hour - a super express result.The first procedure I spent 15 minutes.On the fifth day my teeth started to hurt.At the same time they were never sensitive.Applying strips in the evening, in the morning I woke up with aching pain.Even any sigh caused a sharp pain.It seemed that my teeth were just very tiny.But I wanted a snow-white smile, and I continued to perform bleaching procedures, however, in a day, and then in two.
I used only 10 records.Then it's just scary to use them.I can not imagine how people suffer a course in 20 days.Just want to say that has no special result .True, my lateral teeth were always yellow, and now one tone was white, and almost aligned in color with the front.
In my review I want to tell you how my Crest 3d White strips used strips.He had problems with his teeth, and the dentist recommended him these bleaching sheets.Dad had to do 10 procedures for 30 minutes.One day, half an hour, he could not stand it.Apparently, I stuck the strip on the gum, and irritation began.He immediately removed it and rinsed his mouth, but the gum still ached.Later, he began to glue the plates more carefully.Ten days later the tooth enamel became whiter and cleaner. The effect is stunning !If you do everything strictly according to the instructions and use the plates correctly, you can achieve whitening without any side effects.
I want to share my sad experience.I like to drink coffee and tea, so my enamel is yellow.After reading about the wonderful means of bleaching various rave reviews, I bought a package in an online store.The instructions say that the strips are suitable for sensitive teeth and beginners.After the first procedure, the teeth became slightly whiter, and had no side effects with .
The next day I held the strips for 30 minutes, as stated in the instructions.When I took them off, I discovered that there were "tears" a decent piece of gum.I decided to immediately go to the dentist, who explained to me that this is a chemical burn from the gel that fell under the gum.Now I need to do gingival plastic surgery, because the tooth is very bare.This pleasure is worth 8 thousand rubles.So everyone should decide for himself.Is it worth to conduct over their teeth such experiments on bleaching.
I have ivory tooth enamel.That is not very yellow, but not white.In addition, I really like cola and coffee, which also paint it.But I believe that the girl's teeth should always be beautiful, since a smile is her most attractive and fascinating weapon.And I decided to whiten my teeth.
After reading all possible comments and reviews, chose the Crest 3d White.On the first day of the strip, I held for 30 minutes .The result pleased me.With enamel descent came and it became noticeably whiter.The plates are fastened very simply, but we must make sure that they do not touch the gums.They say that the gel can damage the mucous membrane.For three days my tooth enamel turned white.But literally on the fourth day, side effects began.My teeth are not sensitive, but then they began to ache.I never felt such pain before.I could neither eat nor sleep.Lasts all this about a day.Then everything passes.But if you apply the strips again, the pain returns.
As a result, I did 8 procedures and decided that health is more important.By the way, every day the effect of whitening becomes less and less.Therefore, I stopped using Crest 3d White.After a while, teeth recovered, and the whitening effect disappeared.As if he were not there.
