The only problem is … how to choose a reliable, cheap and not harmful kit? Frankly speaking, it is almost a myth, since there are numerous kits and all of them have their own pros and cons. Everything depends on the price, the way you use it, and the way you clean and maintain your teeth after the whitening process.

Of course, you can go to a dentist and let him do this for you. But I don’t think it is a nice variant. Since the procedure will cost a lot and most likely you will get the same effect as you can achieve at home. The most popular process costs not less than $300 and the most expensive Rembrandt teeth whitener kit costs only $19.00!!!!! Of course, it is not the professional laser treatment but it is not harmful as well.

Most kits are very effective on teeth with yellowish tinge. Their main disadvantage – they seldom practice what they pray. But they still make your teeth look whiter and better without paying the price!
